Raphael bought 2/3 pound bag of sugar. He used 3/4 of it for baking. How many pounds of sugar did he use?

Answer:

(x, y ) → (x + 2, y + 3 )

Step-by-step explanation:

consider the coordinates of the centres of circles A and B

A (- 1, - 1 ) and B (1, 2 )

- 1 → 1 in the x- direction is + 2

- 1 → 2 in the y- direction is + 3

then translation rule is

(x, y ) → (x + 2, y + 3 )

Based on the line of best fit, the length of this catfish can be predicted to be 38 inches.

Given the following data:

A line of best fit is also referred to as a trend line and it can be defined as a statistical (analytical) tool that is used in conjunction with a scatter plot, in order to determine whether or not there's any correlation between a data.

From the graph of the data, we have the following linear equation:

[tex]y=\dfrac{1}{2}x+18[/tex]

Substituting the value of x, we have:

[tex]y=(\dfrac{1}{2}\times40)+18[/tex]

[tex]y=20+18[/tex]

[tex]\bold{y = 38 \ inches.}[/tex]

Answer:  135 + x = 258; x = distance driven on second day (in km).

Step-by-step explanation: Another alternative way to write the equation could be "258 - 135 = x" where x = distance driven on second day (in km).

"x" itself in the case of these equations would be 123km.

The circumference of the outer circle is 72 and circumference of the inner circle is 66.Therefore, the circumference of the outer circle is 6ft greater than the circumference of the inner circle.

We know that the circumference of a circle is given by the formula C = 2πr, where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle.

Given that the circumference of the inner circle is 66ft, we can find its radius by dividing the circumference by 2π:

r = C/2π = 66/(2π) ≈ 10.52ft

The distance between the inner and outer circles is 3ft, so the radius of the outer circle is 3ft greater than the radius of the inner circle:

r_outer = r_inner + 3ft = 10.52ft + 3ft = 13.52ft

Now, we can find the circumference of the outer circle using the same formula as before:

C_outer = 2πr_outer ≈ 72ft

Finally, to find the difference between the circumference of the outer circle and the circumference of the inner circle, we subtract the circumference of the inner circle from the circumference of the outer circle:

C_difference = C_outer - C_inner ≈ 72ft - 66ft = 6ft

Therefore, the circumference of the outer circle is 6ft greater than the circumference of the inner circle.

Zia weighs 4 ounces more than Pia .First, we need to convert Pia's weight from mixed numbers to an improper fraction and then convert the result to ounces to make it comparable to Zia's weight.

Pia's weight = 1 3/4 pounds

= (4*1 + 3)/4 pounds

= 7/4 pounds

= (7/4) * 16 ounces

= 28 ounces

Now we can compare Zia's weight and Pia's weight.

Zia's weight = 32 ounces

Since 32 ounces is greater than 28 ounces, Zia weighs more than Pia.

To find out how much more Zia weighs than Pia, we can subtract Pia's weight from Zia's weight.

Zia's weight - Pia's weight = 32 ounces - 28 ounces = 4 ounces

Therefore, Zia weighs 4 ounces more than Pia.

In summary, we first converted Pia's weight from pounds to ounces by multiplying it by 16. Then we compared the weights of Pia and Zia in ounces and found that Zia weighs more than Pia. Finally, we found the difference between their weights by subtracting Pia's weight from Zia's weight, which showed that Zia weighs 4 ounces more than Pia.

Step-by-step explanation: prime factorize and find common factors, only count those once, take the rest and the common factors and multiply

Answer:

  173.82 cm²

Step-by-step explanation:

You want the area of a regular octagon, given its side length is 6 cm.

A regular n-gon can be divided into n congruent isosceles triangles, each with its a.pex at the center of the polygon. The a.pex angle will have a measure of 360°/n.

The central angle of one sector of a regular octagon is 360°/8 = 45°. That means the triangle interior angle at A or B will be ...

  ∠OAM = (180° -45°)/2

  ∠OAM = 67.5°

The apothem of a regular polygon is the distance from its center to the midpoint of one side. Here, it is the length of segment OM.

We know ∠OAM is 67.5°. The side OM of triangle OAM is related to the side AM by the tangent function:

  Tan = Opposite/Adjacent

  tan(67.5°) = OM/AM

Since M is the midpoint of the 6 cm length AB, the measure of AM = 3 cm. That lets us find OM:

  OM = AM·tan(67.5°) = (3 cm)tan(67.5°)

  OM ≈ 7.2426 cm

The area of the octagon will be 8 times the area of a sector triangle. This, ...

  A = 8(1/2sa) . . . . . . . . . . where s is the side length, and a is the apothem

  A = 4(6 cm)(7.2426 cm)

  A ≈ 173.82 cm²

__

Additional comment

Effectively, we have found a formula for the area of any regular n-gon using only the side length.

  a = s/2·tan(90° -180°/n)

  A = ns/2·a = (1/2)ns·(1/2)s·tan(90° -180°/n)

  A = ns²/(4·tan(180°/n))

For this octagon, the formula gives ...

  A = 8·(6 cm)²/(4·tan(22.5°)) ≈ 173.82 cm²

The formula A = (n/2)sa is often written A = 1/2Pa, where P is the perimeter (=ns).

You may notice that many regular polygon area problems give inconsistent values for the side length and apothem. Specifying one is sufficient for finding the area. Specifying numerical values for both is trouble.

The percentage of students scoring 84 or more in the exam is 99.18%.

Given, Mean test score = 72,

Standard deviation = 5.

We are supposed to find the percentage of students scoring 84 or more in the exam.

To find the percentage of students scoring 84 or more in the exam, we will use the following steps:

First, we need to find the z-score associated with 84.

Let us assume that z is the z-score corresponding to the value 84, then;

z = (84 - 72) / 5 = 2.4

Now, we have the value of z, we can find the percentage of students scoring 84 or more in the exam using the normal distribution table.

The percentage is the area under the normal distribution curve to the right of the z-score.

To find the area using the normal distribution table, we need to look for the value 2.4 in the z-table. Since 2.4 is not exactly listed in the z-table, we will use the value for 2.4 closest to it.

Using the z-table, the value closest to 2.4 is 0.9918.

Therefore, the percentage of students scoring 84 or more in the exam is;

P(Z > 2.4) = 0.9918 × 100 = 99.18%.

Step-by-step explanation:

The closest distance that a cinema can put seats to the screen is approximately 3.2 meters.

the trigonometric functions are real functions that relate an angle of a right-angled triangle to ratios of two side lengths. They are widely used in all sciences that are related to geometry, such as navigation, solid mechanics, celestial mechanics, geodesy, and many others.

We can use trigonometry to find the closest distance that a cinema can put seats to the screen.

Let "d" be the closest distance between the screen and the seats. Then, we can form a right triangle with the distance "d" as the adjacent side, the height of the screen (7.3 m) as the opposite side, and the height of the customer's eyes above the floor (1.2 m) plus the height of the seat above the floor (which we can assume is 0.5 m) as the hypotenuse.

Using the tangent function, we can write:

tan(31°) = (7.3)/(d + 1.7)

Solving for "d", we get:

d = (7.3)/(tan(31°)) - 1.7 ≈ 3.2 m

Therefore, the closest distance that a cinema can put seats to the screen is approximately 3.2 meters.

An average proportion is the sum of a set of proportions divided by the number of proportions.

It represents the average or typical value of the proportions in the set, and can be used to estimate the overall proportion or percentage of a larger population

To estimate the total number of students in the district who are interested in playing hockey, we can first find the proportion of students in each sample who said yes, and then use the average proportion across all four samples to estimate the proportion of students in the district who are interested.

Finally, we can multiply this proportion by the total number of students in the district to estimate the total number of interested students.

The proportion of students in each sample who said yes is:

Sample 1: 4/30 = 0.1333

Sample 2: 5/30 = 0.1667

Sample 3: 5/30 = 0.1667

Sample 4: 3/30 = 0.1000

The average proportion across all four samples is:

(0.1333 + 0.1667 + 0.1667 + 0.1000) / 4 = 0.1417

To estimate the total number of interested students, we can multiply this proportion by the total number of students in the district: Total interested students = 0.1417 x 4,000 = 567.

If  a deadly disease infected the hummingbird population, what would most likely happen to the plants option (b) They would become endangered

If a deadly disease infected the hummingbird population, it would most likely lead to a decrease in the pollination of plants that rely on hummingbirds for pollination. Without the hummingbirds to transfer pollen between flowers, these plants would have a reduced rate of successful pollination, which would result in a decrease in their ability to reproduce.

However, it is unlikely that the plants would die within hours or become endangered immediately, nor would they need to migrate. The effect of the loss of hummingbird pollinators on the plants would depend on the specific plant species, their pollination requirements, and the availability of alternative pollinators. Some plants may be more adaptable to using alternative pollinators, while others may suffer more severe consequences. It is also possible that the loss of hummingbirds could lead to a decline in the populations of other animals that depend on the plants, creating a ripple effect in the ecosystem.

Therefore, the correct option is (d) They would become endangered

Using the surface area of the rectangular prism we know that the dimensions of the base are 2in x 2in.

A three-dimensional solid form with six faces, including rectangular bases, is called a rectangular prism.

A rectangular prism also refers to a cuboid.

A cuboid and a rectangular prism have the same cross-section.

The surface area of the rectangular prism: A=2(wl+hl+hw)

Insert values: A=2(wl+l+hw)

232=2(wl+28l+28w)

232 = 2wl + 56l + 56w

We know that w and l are equal as: w = l as the base is square:

So, we can write:

232 = 2wl + 56l + 56w

232 = 2w² + 56w + 56w

232 = 2w² + 112w

2w² + 112w - 232 = 0

2w² + w(116 - 4) -232

2w² + 116w - 4w - 232

2w(w+58) -4(w+58)

Then, we have:

w+58 = 0 ⇒ w = -58

2w-4 = 0 ⇒ w = 2

Since the base measurements cannot be negative.

Then, the dimensions of the base are: 2in x 2 in

The comparison of variance that is true for the given average per month is "May > July".

Variance is a metric for gauging how dispersed a set of data is. The average of the squared discrepancies between each data point and the data set mean is used to compute it. Data points with a high variation are dispersed throughout a wider range of values, whereas those with a low variance are grouped more closely together. In statistics, variability is frequently used to examine data distribution and contrast the variability of various data sets. It is frequently stated in terms of the original data's square units, such square metres or square dollars.

From the given table the average per month is:

April: $6 million - $2.5 million = $3.5 million below average

May: $6 million - $2 million = $4 million below average

June: $6 million + $3.1 million = $9.1 million above average

July: $6 million - $1.6 million = $4.4 million below average

Advik spends $24.50 at the home goods store on a bird bath and $2.79 a bag for multiple mulch bags. His total before tax for the purchase is $66.35. 15 sacks of mulch were bought by Advik.

Let's start by first finding the total cost of the bird bath and the mulch bags.

The cost of the bird bath is $24.50.

Let's use "x" to represent the number of bags of mulch that Advik purchased. Each bag costs $2.79, so the total cost of the mulch bags is 2.79x.

The total cost of the purchase before tax is $66.35. So we can write an equation:

24.50 + 2.79x = 66.35

To solve for x, we can first subtract 24.50 from both sides:

2.79x = 41.85

Then we can divide both sides by 2.79:

x = 15

So Advik purchased 15 bags of mulch.

Step-by-step explanation:

The interior angles of a triangle sum to 180°.

Given the ratio of the interior angles of a triangle is 1 : 1 : 4 then:

x + x + 4x = 180°

Solve the equation for x:

⇒ 6x = 180°

⇒ x = 30°

Therefore, the angle measures are:

So the angle measures from least to greatest are 30°, 30° and 120°.

Answer:

30 , 30 , 120 .

Step-by-step explanation:

Given :

To find :

Solution :

As we know that the angle sum property is 180° , that is the sum of all the interior angles is 180° .

Let us take the given ratio to be 1x:1x:4x .

Sum of these= 1x + 1x + 4x = 6x .

So we can create a equation as ,

==> 6x = 180°

==> x = 180°/6

==> x = 30°

Now we can find the angles as ,

Hence the angles of the triangle are 30° , 30° and 120° .
