Answer:

n = 5

Step-by-step explanation:

5 * (n/5) = 5 / (n/5)

(5 * n) /5  = 5 * (5/n)          

n   = ( 5*5) / n

n = 25/n

n² = 25

n = 5

To calculate the change in volume of a box when cutout length increases from 0.3 inches to 1.2 inches using function notation, use the formula ΔV=f(l2)-f(l1), where f(l) represents the volume of the box given the length of the edge.

The change in volume when the cutout length increases from 0.3 inches to 1.2 inches can be represented in function notation as ΔV=f(l2)-f(l1), where f(l) represents the volume of the box as a function of the length (l) of the edge. Here, l1=0.3 and l2=1.2.

Given the formula for the volume of the box V = Length x Width x Height. Let's assume Width and Height remain constant. If initially the volume was V1=f(l1) and finally it became V2=f(l2), the change in volume will be ΔV=V2-V1 which equals f(l2)-f(l1).

For example, if the width and height of the box are 6 inches and 3 inches respectively, then the initial volume is V1 = 0.3 x 6 x 3 cubic inches and the final volume is V2 = 1.2 x 6 x 3 cubic inches. Therefore, ΔV = (1.2 x 6 x 3) - (0.3 x 6 x 3) cubic inches.

The change in the volume of the box when the cutout length increases from 0.3 inches to 1.2 inches can be calculated using the function ΔV = V(1.2) - V(0.3). Assuming the rest of the box's dimensions are constant, this results in a change in volume of 16.2 cubic inches.

To use function notation to represent how the volume of the box changes by if the cutout length increases from 0.3 inches to 1.2 inches, let us first define a function V(l) that represents the volume of the box as a function of the cutout length 'l'. If the initial cutout length is 0.3 inches and the final cutout is 1.2 inches, the change in length Δl would be 1.2 inches - 0.3 inches = 0.9 inches. We can express the change in volume, ΔV, as the function of the change in cutout length as follows: ΔV = V(1.2) - V(0.3).

Given that the volume of a rectangular box can be calculated by the formula volume = length × width × height, and assuming other dimensions of the box do not change, the function V(l) becomes:

V(l) = length × width × l

Let's consider an example where the dimensions of the box remain constant at 6 inches by 3 inches. The volume function would then be:

V(l) = 6 in. × 3 in. × l in.

The change in volume for an increase in cutout from 0.3 to 1.2 inches is then:

ΔV = V(1.2) - V(0.3) = (6 × 3 × 1.2) - (6 × 3 × 0.3) = 21.6 in.³ - 5.4 in.³ = 16.2 in.³.

Step-by-step explanation:

Because they just added the same equality. And when you move the -7 over the equal sign it makes it positive so it would be p^2 + 5 + 7 = 8p and that makes it p^2 + 12 = 8p

The property used by the kate to write the function p^2 + 5 = 8p - 7 as p^2 + 12 = 8p is the addition property of equality.

Given to us

When solving p^2 + 5 = 8p - 7.

Kate wrote p^2 + 12 = 8p.

As we can see Kate has simply added the number one, therefore, she had used the addition property of equality.

[tex]p^2 + 5 = 8p - 7\\\\p^2+5+7=8p\\\\p^2 + 12=8p[/tex]

So, [tex]x[/tex] represents the number of sandwiches and [tex]y[/tex] represents the number of wraps, so the profit on each food is

Answer:

Step-by-step explanation:

40%=0.4

0.4*25=10

To calculate 40 percent of 25, you use the equation 0.40 x 25. This equation multiplies the decimal form of 40 percent by the total, which in this case is 25, resulting in the value of the part that represents 40 percent.

To find 40 percent of 25, you can use the equation that incorporates the base value (25) and the percentage you want to find (40%). In this case, the equation you're looking for is 0.40 x 25, which will give you the answer for what is 40 percent of 25.

Percentages can be calculated by using the formula: 'part over total, times one hundred, equals percent'. For example, if you have 25 students and want to find out what 40% of that number is, you would calculate 40/100, which is 0.40, and multiply by 25. The equation 0.40 x 25 is thus used to solve for the desired percentage.

Answer:

x = 13.

So the 3 angles are a =  44, b = 47 and c = 89 degrees.

Step-by-step explanation:

If these are the angles  are the 3 angles of a triangle they sum to 180 degrees, so:

3x + 5 + 5x - 18 + 7x - 2 = 180

15x - 15 = 180

15x = 195

x = 195/15

x = 13.

To find the values of angles a, b, and c given by the expressions 3x + 5, 5x - 18, and 7x - 2, we set up and solve equations involving these expressions. Once we find the value of x, we substitute it back into the expressions to find the angles.

The question asks about angles given by the expressions a= 3x + 5, b= 5x - 18, and c= 7x - 2. In order to find the values of x and the corresponding values of angles a, b, and c, we need to set up and solve equations involving these expressions.

We can equate these expressions to given angles or to each other, and solve for x. Once we find the value of x, we can substitute it back into the expressions to find the angles.

For example, to find angle a, we substitute the value of x into the expression 3x + 5. Similarly, we substitute the value of x into the expressions 5x - 18 and 7x - 2 to find angles b and c, respectively.
