Answer: 7.5

Step-by-step explanation: Because Noah has five dollars, 100% of 5 is 5, and 50% of 5 is 2.5 so Diego has 7.5 dollars.

Answer:

$7.5

Step-by-step explanation:

There are two ways to solve this:

1) First, write the equation:

150% of 5

Then calculate:

[tex]\frac{150}{100} *5[/tex]

Finally, simplify 1 zero with the 0 in 15:

1.5 * 5

= $7.5

2) For the second way, because 150 is more than over 100 (percent), you deduct 150 and 100:

150 - 100 = 50

Then find 50% of 50:

[tex]\frac{50}{100} *5[/tex]

Then cancel 1 zero in 100 with the zero in 50:

0.5 * 5

= 2.5

Finally, add the product with the original amount of Noah:

5 + 2.5

= $7.5

The distance traveled after t seconds is given by:

[tex]d = |-\frac{(2t^2 + 2t + 1)e^{-2t}}{4}|[/tex]

Here we know that the particle moves along a straight line with the velocity:

[tex]v(t) = t^2*e^{-2t}[/tex]

Remember that the velocity is the rate of change of the position, so if we want to find the distance traveled after t seconds, we need to integrate this between 0 and t, we will get:

[tex]\int\limits^t_0 {t'^2*e^{-2t'}} \, dt' = -\frac{(2t^2 + 2t + 1)e^{-2t}}{4}[/tex]

That is the expression that gives the distance traveled after t seconds, if we want to get it more exactly, we should take the absolute value, then we get:

Probability in sandwich choices analysis refers to the likelihood of a particular sandwich being chosen, based on factors such as taste, price, and availability.

1. To calculate the total number of possible sandwiches, we need to consider the number of options for each category: bread, protein, cheese, and vegetables.

Bread: There are 3 options - Italian, white, and wheat.

Protein: There are 4 options - tuna, ham, turkey, and beans.

Cheese: There are 4 options - provolone, Swiss, American, and none.

Vegetables: There are 5 options, and since we need to choose two, we use combinations. Therefore, there are (5 choose 2) = 10 possible combinations of vegetables: lettuce and tomatoes, lettuce and peppers, lettuce and onions, lettuce and pickles, tomatoes and peppers, tomatoes and onions, tomatoes and pickles, peppers and onions, peppers and pickles, and onions and pickles.

To calculate the total number of possible sandwiches, we multiply the number of options for each category:

3 x 4 x 4 x 10 = 480

Therefore, there are 480 different possible sandwiches.

2. Since Andre only cares about the ham, lettuce, and tomatoes, we only need to consider the number of options for vegetables. He needs to choose two vegetables, so we need to count the number of possible combinations of lettuce, tomatoes, and the remaining vegetables. Since we don't care about the bread or cheese, we can ignore those options.

There are (3 choose 2) = 3 possible combinations of vegetables that would make Andre happy: lettuce and tomatoes, lettuce and peppers, or tomatoes and peppers. Since we don't care about the bread or cheese, there are no restrictions on those categories, so there are 4 options for cheese and 3 options for bread, for a total of 12 possible sandwiches that would make Andre happy.

3. To calculate the probability of randomly choosing a sandwich that would make Andre happy, we divide the number of sandwiches that would make him happy by the total number of possible sandwiches:

3/480 = 1/160

Therefore, the probability is 1/160, or approximately 0.00625. This means that if we were to randomly choose a sandwich, there is a 0.625% chance that it would be a sandwich that would make Andre happy.

The complete question is:

1. A submarine sandwich shop makes sandwiches with one kind of bread, one protein, one choice of cheese, and two vegetables. How many different sandwiches are possible? Explain your reasoning. You do not need to write out the sample space.

Breads: Italian, white, wheat

The cube's surface area would be 96m².

The surface area of the right rectangular prism is 37.5 ft².

The height of the prism is 4/3 in.

The approximate lengths of the sides of the base is height of 9 cm and a base of 8.2 cm.

To find the surface area, first find the side length of the cube. The volume of a cube is V = s³, where s is the side length. So:

64m³ = s³ => s = (64)^(1/3) = 4m

Now, the surface area (SA) of a cube is given by the formula SA = 6s². Plugging in the side length:

SA = 6(4m)² = 6(16m²) = 96m²

To find the surface area of the right rectangular prism:

First, find the Lateral Area (LA): LA = Perimeter × height

Perimeter = (2 ft + 1 1/2 ft) × 2 = 7 ft

Height = 4 1/2 ft

LA = 7 ft × 4 1/2 ft = 31.5 ft²

Now, find the Surface Area (SA): SA = LA + 2B

SA = 31.5 ft² + 2(3 ft²) = 31.5 ft² + 6 ft² = 37.5 ft²

To find the height h of the prism:

First, find the Base Area (B): B = Length × Width

B = 3 in × 7 in = 21 in²

Now, use the Surface Area (SA) formula to find the Lateral Area (LA):

SA = LA + 2B => LA = SA - 2B

LA = 68 2/3 in² - 2(21 in²) = 68 2/3 in² - 42 in² = 26 2/3 in²

Now, use the Lateral Area (LA) formula to find the height (h):

LA = Ph => h = LA / P

Perimeter (P) = 2(Length + Width) = 2(3 in + 7 in) = 20 in

h = (26 2/3 in²) / 20 in = 4/3 in

The right triangular prism has two equilateral triangular bases and three rectangular sides. Since the distance between the bases is 9 cm, we can use the surface area of the prism to find the total area of the three rectangular sides:

Surface area = 2 * A (triangle bases) + Lateral area (rectangular sides)

319.5 cm² = 2 * 29.1 cm² + Lateral area

Lateral area ≈ 261.3 cm²

Each of the three rectangular sides has a height of 9 cm and a base of 8.2 cm.

the solution to the system of equations is x = 7.14 and y = 13.57.

In mathematics, an equation is a statement that asserts the equality of two mathematical expressions, usually containing one or more variables.

Given equations are:

5 - 0.7x = 0.2y ...........(1)

-y + 0.4x = 4.3 ...........(2)

To solve for x and y, we can use the elimination method, which involves multiplying one or both equations by a constant to eliminate one of the variables. Here's how we can do it:

First, let's multiply equation (1) by 5 and equation (2) by 2 to eliminate the y variable:

25 - 3.5x = y (multiplying equation (1) by 5)

-2y + 0.8x = 8.6 (multiplying equation (2) by 2)

Now we can substitute the expression for y from equation (1) into equation (2) and solve for x:

25 - 3.5x = 0.2(25 - 3.5x) (substituting y from equation (1))

25 - 3.5x = 5 - 0.7x

-2.8x = -20

x = 7.14

Substituting this value of x back into equation (1), we can solve for y:

5 - 0.7(7.14) = 0.2y

y = 13.57

Therefore, the solution to the system of equations is x = 7.14 and y = 13.57.

By using ALEKS graphing calculator, we get the same values of x and y.

the correct answer is option b) 0.11. To find the experimental probability of drawing a K or 6, we need to first determine how many K's and 6's are in a standard deck of cards.

A standard deck of cards contains 52 cards, divided into four suits: hearts, diamonds, clubs, and spades. Each suit contains 13 cards, including an ace, numbered cards 2-10, and face cards (jack, queen, king).

Out of the 52 cards in the deck, there are four K's and four 6's, for a total of eight cards that satisfy the condition of being a K or 6.

To calculate the experimental probability of drawing a K or 6 from the table, we need to add up the frequency of drawing a K and the frequency of drawing a 6, and then divide by the total number of draws (100).

From the table, we see that the frequency of drawing a K is 4, and the frequency of drawing a 6 is 7. Therefore, the total frequency of drawing a K or 6 is:

4 (K's) + 7 (6's) = 11

So the experimental probability of drawing a K or 6 is:

11/100 = 0.11

Therefore, the correct answer is option b) 0.11.

The horizontal distance between the center of circles P and Q is 11.70 units

The scale factor of dilation from circle P to Q is 2.5

The horizontal distance between their centers?

From the figure, we have the centers to be:

P = (-5,4)

Q = (6,8)

The distance is then calculated using:

d = √(x2 - x1)^2 + (y2 - y1)^2

So, we have:

d = √(6 + 5)^2 + (8 - 4)^2

Evaluate the sum

d = √137

Evaluate the root

d = 11.70

Hence, the horizontal distance between the center of circles P and Q is 11.70 units

The scale factor of dilation from circle P to Q

We have their radius to be:

P = 2

Q = 5

Divide the radius of Q by P to determine the scale factor (k)

k = Q/P

k = 5/2

Length is a physical quantity that describes the distance between two points. It is typically measured in units such as meters, feet, inches, centimeters, or kilometers. Length can refer to the size of an object or the distance traveled by an object over a period of time. In geometry, length refers to the size of a line segment, which is the distance between two points in a plane. In physics, length is a fundamental concept that is used to describe the size of objects and the distances between them, and is an important factor in many calculations involving motion, energy, and other physical phenomena.

To find the length of side z, we can use the Law of Sines, which states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle.

Using this law, we have:

[tex]z/sin(141°) = x/sin(25°)[/tex]

Solving for z, we get:

[tex]z = x*sin(141°)/sin(25°)[/tex]

[tex]z = 830*sin(141°)/sin(25°)[/tex]

z ≈ 2329.9 cm

a quadratic function means it has an "x²" based term as highest x exponent.

the request here simply means that both zeros must be equal and 5.

remember, factoring the function expression tells us the zeroes right away.

now we reverse the process.

we know the zeroes (5 - two times).

so we define the factors to have the desired zeroes :

y = (x - 5)(x - 5)

you see what i did there ? we need to have a quadratic equation, and therefore 2 zeroes. both with the value of 5.

y = (x - 5)(x - 5) = x² - 5x - 5x + 25 = x² - 10x + 25

A quadratic function with only one zero can be derived using the vertex form of a quadratic function, where h equals the zero. Hence, a possible quadratic function with five as the only zero is f(x) = (x - 5)^2.

In mathematics, a quadratic function is written in the form f(x) = ax2 + bx + c.

Water output rate for Mitchell family's sprinkler was 20 L per hour and for Garcia family's sprinkler was 15 L per hour. Their sum is 35 L per hour and total water output was 1075L of water.

Let's denote the water output rate of the Mitchell family's sprinkler by x and the water output rate of the Garcia family's sprinkler by y. We know that the sum of the two rates is 35 L per hour, so equation:

x + y = 35

We also know that the Mitchell family's sprinkler was used for 35 hours, so it produced a total of 35x liters of water. Similarly, the Garcia family's sprinkler was used for 25 hours, so it produced a total of 25y liters of water. The combined total output of 1075L of water will be written as:

35x + 25y = 1075

We use first equation to solve for one of variables in terms of the other. For example, we solve for y:

y = 35 - x

Now substitute this expression for y into second equation:

Answer:

To find the average rate of change of a function over an interval, you can use the formula:

average rate of change = [f(b) - f(a)] / (b - a)

where a and b are the endpoints of the interval.

In this case, you have the function g(x) = log2(x + 3) - 4 and the interval [-2, 5]. So, plugging in the values, you get:

average rate of change = [g(5) - g(-2)] / (5 - (-2))

First, let's evaluate g(5) and g(-2).

g(5) = log2(5 + 3) - 4 = log2(8) - 4 = 3 - 4 = -1

g(-2) = log2((-2) + 3) - 4 = log2(1) - 4 = 0 - 4 = -4

Now you can substitute these values into the formula:

average rate of change = (-1 - (-4)) / (5 - (-2))

= 3 / 7

And the average rate of change of g(x) over the interval [-2, 5] is 3/7.

In mathematics, ratios demonstrate how frequently one number is contained in another. For example, if there are 8 oranges and 6 lemons in a fruit plate, the ratio of oranges to lemons is 8 to 6. In a similar vein, the orange-to-whole-fruit ratio is 8, whereas the lemon-to-orange ratio is 6:8. A ratio is an ordered pair of integers a and b represented as a / b, where b is not zero. A ratio is an equation that equates two ratios. For example, if there is one male and three girls (for every boy she has three daughters), 3/4 are girls and 1/4 are boys.

If the concentrate-to-water ratio is 1:7, it signifies that the final product requires 7 parts water for every 1 part concentrate. As a result, the total number of components in the combination is 1+7=8.

To produce 5 litres of the cold drink, we must first establish the quantity of concentrate necessary to make 8 parts, and then multiply this figure by 5 litres.
