Find the unit rates,
then find which has the better value


10 oz, $2.50 or 14 oz, $3.65​

Answers

Answer 1

The unit rate among these for the better values is: 0.25

What further instances of unit rates can you give?

These are a few illustrations of unit rates :The distance travelled in one hour is measured in miles per hour (mph); the price of an item is measured in pounds; and the price of an electrical kilowatt-hour is measured in kWh.

- Price per gallon - the price of a liquid per gallon.

The quantity of calories in one serving of food is known as the "calories per serving."

Now , divide the price by the weight to obtain the unit rate.

The unit rate for the first choice is:

2.50 / 10 = 0.25

The unit rate for the second choice is:

3.65 / 14 = 0.26

Due to its lower unit rate, the first choice is therefore more advantageous.

The right rectangular prism shown has a
volume of 115 cubic yards. What is the length
of the prism?
width is 2 1/2 and hight is 5 3/4

Answers

Therefore, the length of the rectangular prism is 16 yards.

How to find length of rectangular prism?

To find the length of a rectangular prism, you need to measure the distance between its two opposite faces that are parallel to each other.

Here are the steps you can follow to find the length of a rectangular prism:

Identify the two opposite faces of the rectangular prism that are parallel to each other.

Choose one of these faces and measure its length using a ruler or tape measure. This will be the length of the rectangular prism.

If the rectangular prism is too large to measure directly, you can use a formula to calculate its length. The formula for finding the length of a rectangular prism is:

length = volume / (width x height)

To find the length of the rectangular prism, we can use the formula for the volume of a rectangular prism, which is:

Volume = length x width x height

We are given that the width is 2 1/2 and the height is 5 3/4. We also know that the volume is 115 cubic yards. So, we can plug these values into the formula and solve for the length:

115 = length * 2.5 * 5.75

Dividing both sides by (2.5 x 5.75), we get:

length = 115 / (2.5 * 5.75)

length = 16

the ratio h:m is 5:4 and the ratio m:t is 3:2. write the ratio h:m:t in its simplest form

Answers

The ratio of h:m:t in its simplest form is 15:12:8.To find the ratio of h:m:t, we need to use the given ratios h:m = 5:4 and m:t = 3:2 and simplify them to express them in terms of h, m, and t.

From the ratio h:m = 5:4, we can write:

m = (4/5)h

Similarly, from the ratio m:t = 3:2, we can write:

t = (2/3)m

Substituting the value of m from the first equation into the second equation, we get:

t = (2/3)(4/5)h

Simplifying this expression, we get:

t = (8/15)h

Therefore, the ratio of h:m:t can be expressed as:

h : m : t = h : (4/5)h : (8/15)h

Simplifying this ratio by multiplying all the terms by the least common multiple of the denominators (15), we get:

h : m : t = 15h : 12h : 8h

Simplifying further by dividing all the terms by the greatest common factor (h), we get:

h : m : t = 15 : 12 : 8

(i.e., /- 0.05).

Answers

The probability that your survey will provide a sample proportion within 0.05 of the population proportion = 0.8818

Here,  people end up tossing 10% of what they buy at the grocery store

So, the probability of occurance P = 0.1

q = 1 - p

q = 1 - 0.1

q = 0.9

Also, the sample size (n) = 90

Now the standard error of the distribution of sample means would be,

s = [tex]\sqrt{\frac{p\times q}{n} }[/tex]

s = 0.032

We need to calculate the probability that your survey will provide a sample proportion within 0.05 of the population proportion.

z₁ = (-0.05)/(0.032)

z₁ = -1.5625

z₂ = (+0.05)/(0.032)

z₂ = +1.5625

p(z-score between -1.5625 and +1.5625) = 0.8818

How to solve proportional graph?

The graph of a proportional relationship is always a straight line through the origin.

Therefore, the graph is a relationship between the variables volumes in litres and gallons. The litres is on the y axis while the gallons is on the x axis.

Hence, let's use the graph to convert the volumes.

11 gallons = 50 litres

40 litres = 8.8 litres

A tank has a volume of 120, 000 cm cube.

1 litre  = 1000 cm³

The capacity of the tank in gallons can be found as follows:

1000 cm³ = 1 litres

120,000 cm³= ?

volume in litres = 120,000 / 1000

volume in litres = 120 litres

From the graph,

36 litres = 8 gallons

120 litres = ?

cross multiply

volume in gallons = 120 × 8  / 36

Step-by-step explanation:

Given a graph showing the relationship between (imperial) gallons and litres, you want equivalents for 11 gallons, 50 litres, and 120000 cm³.

a) 11 gallons

You have correctly read the graph, which tells you 11 gallons is about 50 litres.

b) 40 litres

Therefore , the solution of the given problem of triangle comes out to be    h/s = h/√(h² - s²)..

A triangle is exactly what?

If a polygon has at least one additional segment, it is a hexagon. Its form is a straightforward rectangle. Something like this can only be distinguished from a regular triangular by edges A and B. Euclidean geometry only creates a portion of the cube, despite the precise collinearity of the borders. A triangular has three sides and three angles.

Here,

Triangle ABC and triangle ACD are both right triangles with a common hypotenuse, as shown by the given diagram.

Let's write the lengths of the sides AB or AD as s and the hypotenuse AC as h. (since both triangles have a common side with length s).

The Pythagorean formula can now be used to determine the length of each triangle's third side:

Triangle ABC's third side's length (BC) can be calculated using this formula:

=> BC = √(h² - s²).

The third side's (CD) length in the triangle ACD is also determined by:

=> CD = √(h² - s²).

By dividing each triangle's hypotenuse's (h) length by one of its sides' (s) lengths, the following result is obtained:

In the triangular ABC,

=> h/s = h/ √(h² - s²).

What are two possible expressions equal to the product of 2 and 1 3/6

Answers

The product of 2 and 1 3/6 can be expressed as either 18/6 or 3

The product of 2 and 1 3/6 can be found by multiplying 2 by the mixed number 1 3/6. To do this, we need to convert the mixed number to an improper fraction, then multiply it by 2. Here are two possible expressions that are equal to the product of 2 and 1 3/6

Improper fractions

2 x 1 3/6 = 2 x (1 + 3/6) = 2 x (6/6 + 3/6) = 2 x 9/6 = 18/6

Therefore, the product of 2 and 1 3/6 is equal to 18/6.

Decimals

We can also convert the mixed number 1 3/6 to a decimal and then multiply it by 2. To convert the mixed number to a decimal, we divide the numerator (3) by the denominator (6), which gives us 0.5. Then we add the whole number (1) to get 1.5.

2 x 1.5 = 3

Therefore, the product of 2 and 1 3/6 is equal to 3.

Point B has coordinates ​(3,​1). The​ x-coordinate of point A is -3. The distance between point A and point B is units. What are the possible coordinates of point​ A?

Answers

We have two possible values for y, we have two possible Coordinates for point A: (-3, 1 + √((units)² - (3 - (-3))²)) and (-3, 1 - √((units)² - (3 - (-3))²)).

Here are the terms and steps we'll use in the solution:

1. Point B coordinates: (3, 1)
2. Point A x-coordinate: -3
3. Distance formula: √((x2 - x1)² + (y2 - y1)²)

Let's find the possible coordinates of point A:

Step 1: We know the x-coordinate of point A is -3, so its coordinates will be in the form (-3, y).

Step 2: Apply the distance formula to find the distance between point A (-3, y) and point B (3, 1):

Distance = √((3 - (-3))² + (1 - y)²)

Step 3: Square the distance equation to eliminate the square root:

Distance² = (3 - (-3))² + (1 - y)²

Step 4: Plug in the given distance value and solve for y:

(units)² = (3 - (-3))² + (1 - y)²

Step 5: Solve for (1 - y)²:

(1 - y)² = (units)² - (3 - (-3))²

Step 6: Take the square root of both sides:

1 - y = ±√((units)² - (3 - (-3))²)

Step 7: Solve for y:

y = 1 ±√((units)² - (3 - (-3))²)

Since we have two possible values for y, we have two possible coordinates for point A: (-3, 1 + √((units)² - (3 - (-3))²)) and (-3, 1 - √((units)² - (3 - (-3))²)).

an a-frame tent is in the shape of an isosceles triangle. the base of the triangle is 7 ft and the two congruent sides are each 6 ft. what is the height of the tent

Answers

The height of the tent is approximately 4.87 feet.

To find the height of the tent, we need to first determine the length of the altitude (perpendicular line) drawn from the apex (top point) of the triangle to the base. Let's call this length "h".

We can use the Pythagorean theorem to find "h". Let's draw a line from the apex of the triangle to the midpoint of the base, which will split the isosceles triangle into two congruent right triangles. Then we have

h^2 + (7/2)^2 = 6^2

h^2 + 49/4 = 36

h^2 = 36 - 49/4

h^2 = 95/4

h = sqrt(95)/2

The answer of the given question based on Return on Investment is (a) 19.64% , (b) $51,575 , (c)  -28.30% , (d)  $42,000.

What is Investment?

Investment is the act of allocating resources, like money, time, or effort, with the expectation of generating a return or profit in the future. Investment can take many forms, including purchasing stocks, bonds, mutual funds, real estate, or other financial assets.

The main goal of investment is to grow wealth over time by generating returns that exceed the rate of inflation. There are several types of investment strategies, such as value investing, growth investing, income investing, and diversification, that investors can use to achieve their financial goals.

a. ROI = (final value - initial value)/initial value * 100%

ROI = (67000 - 56000)/56000 * 100% = 19.64%

b. ROI = (final value - initial value)/initial value * 100%

$24,756 = 48% * initial value

initial value = $24,756 / 0.48 = $51,575

c. ROI = (final value - initial value)/initial value * 100%

ROI = ($62.56 - $87.24)/$87.24 * 100% = -28.30%

The negative ROI indicates a loss in investment.

d. The lowest price is $25 and the highest price is $67, so the total return on investment is:

Total Return = 1000 shares * ($67 - $25) = $42,000.

]]] explanation:

you operate a tour service that offers the following rates: $600 per person if 30 people (the minimum number to book the tour) go on the tour. for each additional person, up to a maximum of 130 people total, the rate per person is reduced by $3. it costs $7380 (a fixed cost) plus $390 per person to conduct the tour. how many people does it take to maximize your profit?

Answers

67 people can maximize the profit.

Let's aasume that x represent the number of people.

so, the number of people on the tour = x + 50

The cost function would be:

C = 6000 + 32x

and the revenue:

R = (200 - 2x)(50 + x)

R = 10000 - 100x + 200x - 2x^2

R = 10000 + 100x - 2x²

So, the profit would be:

P = R - C

P = 10000 + 100x - 2x² - 6000 - 32x

P = 4000 + 68x - 2x²

Now we take the derivative of profit function:

P' = 68 - 4x

Consider P'(x) = 0

68 - 4x = 0

4x = 68

x = 17

So, the number of people on tour: 50+17 = 67

This means that 67 people can maximize the profit.

and the profit would be:

P = 4000 + (68 × 17) - (2 × 17²)

The graph that shows the residual plot for the height and weight of the 10 players is B. Graph B.

How to find the residual plot ?

To find the residual plot, you need to use the data on height and weight of 10 players shown on the table, and compare it to figures you get from the formula given of y = -146.7 + 4.76 x.

Doing this, we find two residuals being:

x = 68

Predicted y = -146.7 + 4.76(68) = 175.88

Actual y = 170

Residual = Actual y - Predicted y = 170 - 175.88 = -5.88

x = 70

Predicted y = -146.7 + 4.76(70) = 185.3

Actual y = 185

Residual = Actual y - Predicted y = 185 - 185.3 = -0.3

These points of (68, - 5.88) and ( 70, - 0.3) tally with Graph B so this is the residual plot.

angle is constructed with its base on the x-axis and its upper two vertices on the parabola . what are the dimensions of the rectangle with the maximum area? what is the area?'

Answers

The double integral of sin(xy) over the rectangle r equals 1 when a is approximately equal to 0.986, with 0 ≤ a ≤ π.

The iterated integral to compute the double integral over the rectangle r = {(x,y) : 0 ≤ x ≤ π, 0 ≤ y ≤ a} of sin(xy) is given by:

∫∫r sin(xy) dA = ∫₀^a ∫₀^π sin(xy) dx dy

Integrating with respect to x first, we have:

∫₀^a ∫₀^π sin(xy) dx dy = ∫₀^a [-cos(πy) + cos(0)] dy

= ∫₀^a (1 - (-1)^n) dy

= a - (a/π)sin(πa)

For what values of a is ∫∫r sin(xy) dA equal to 1?

We need to solve the equation:

a - (a/π)sin(πa) = 1

Multiplying both sides by π, we get:

aπ - a sin(πa) = π

Now, let f(a) = aπ - a sin(πa) - π. We need to find the values of a such that f(a) = 0.

Using numerical methods, we can find that there is only one solution in the interval [0,π], which is approximately a = 0.986.

Therefore, the double integral of sin(xy) over the rectangle r equals 1 when a is approximately equal to 0.986, with 0 ≤ a ≤ π.

A circle has a Centre at (1,2). One point on its circumference is (-3,-1). What is the radius of the circle?

Answers

Answer:

5

Step-by-step explanation:

In the given question,

center of the circle C = (1, 2)

let P be the point (-3, -1) on the circle (on circumference)

radius of the circle is equal to the distance between the center and any point on its circumference.

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex] (distance between two points)

therefore,

[tex]r = \sqrt{(-3 - 1)^2 + (-1 - 2)^2}[/tex]

[tex]r = 5[/tex]

you are using. Also find
(b) critical z-value (not the p-value!)
(c) test value

Answers

After answering the provided question, we can conclude thatAs a result, null hypothesis there is sufficient evidence to support John's claim that more than 25% of Wenatchee residents prefer Taco Bell.

What is null hypothesis?

A null hypothesis is a type of statistical hypothesis that asserts that a specific set of observations has no statistical significance. Sample data is used to assess the viability of theories. H0 represents what is referred to as "zero" on occasion. The researchers make the assumption that there may be a relationship between the factors. The null hypothesis, which is on the other hand, claims that no such relationship exists. Although it may not appear to be significant, the null hypothesis seems to be an important part of research.

(a) p = 0.25 for the null hypothesis

p > 0.25 is an alternative hypothesis.

To test this hypothesis, we can use the z-Test for proportion.

(b) \s(c) (c) The test value can be calculated using the z-Test for proportion formula:

(p - p) / (p(1-p)/n) = z

where p represents the sample proportion, p represents the hypothesised population proportion, and n represents the sample size.

p = 63/200 = 0.315, p = 0.25, and n = 200 in this case. When we enter these values into the formula, we get:

z = (0.315 - 0.25) / √(0.25 * 0.75 / 200) = 2.34

The result of the test is 2.34.

(d) Because the test value (2.34) is greater than the critical z-value (1.645), the null hypothesis is rejected. As a result, there is sufficient evidence to support John's claim that more than 25% of Wenatchee residents prefer Taco Bell.

Papa John's is offering a special on large pizzas. The advertisement reads "Purchase any large pizza at regular price and pay only $6 for each additional large pizza". If Ralph purchased 7 pizzas for $58 (tax free), writing your equation from problem #3 in slope intercept form, you find the regular price of the first large pizza Ralph purchased to be $____________________________. (Your answer should be a whole number, do not include the dollar symbol or a decimal)

Answers

Answer:

22

Step-by-step explanation:

To find out how much the other pizzas cost you need to do 7-1 because that is the other 6 pizzas not including the 1st pizza. Then multiply 6 x 6 because that is the total cost for the other pizzas after the first pizza bought. This means that the pizzas cost 36 dollars without the first pizza. Then do 58-36 for the first pizza cost which is 22 dollars. Therefore the regular price of the first large pizza is 22 dollars. If you were to write it in slope intercept form it would be Y=6x+16 {x[tex]\geq[/tex]1} with Y representing the cost and x representing the pizza. You would need a domain as if you were to buy 0 pizza it wouldn't mean that it would cost you 16 dollar. Which is why you want the domain to be greater than or equal to 1 because if you bought 1 pizza it would cost 22 dollars
