Answers

Answer:

90deg

Step-by-step explanation:

If the angles are supplementary, that means mA + mB = 180*

we know that

mA = (2x + 8)deg

mB = (2x + 8)deg = mA

mA + mB = 180deg

mB + mB = 2mB = 180deg

mB = 90deg

Note, that we did not need to compute x even, because the angles were the same.

a model plane has a scale of 1 in: 2 ft. if the real plane is 12 ft tall then how tall is the model plane.

Answers

Answer:

6ft tall

Step-by-step explanation:

Given we know that the scale is 1 in 2ft.

Using this information we know we could divide 12/2=6. We also know that we could multiply 2×6=12. Therefore, we know that the model plane is 6ft tall.

I hope this helps!

Which of the following do you use to tell whether a relationship is
proportional or not?

Answers

Answer:

The correct option to tell whether a relationship is proportional or not is;

[tex]\dfrac{y}{x}[/tex]

Step-by-step explanation:

A proportional relationship is a relationship between two variables, 'x', and 'y' such that they have equivalent ratio, such that all values of variable 'y' are given by the product of the values of the variable 'x' and a constant, 'k'

Therefore, y = k · x, from which we have;

[tex]\dfrac{y}{x} = k = Contant[/tex]

Therefore we can use [tex]\dfrac{y}{x}[/tex] to tell whether a relationship is proportional or not proportional.

Answer:

g has an average rate of change of zero at the intervals [-5,4] and [-2,2]

Step-by-step explanation:

When we talk of the average rate of change, we mean the change in y values divided by the change in x values

Once the change in y-values is zero, then over that interval, the average rate of change is zero

at the point t =- 5, g(t) = 6; at the point t = 4, g(t) = 6

As we can see here, within the interval [-5,4]; the average rate of change is 0

This same pattern is repetitive at points or ranges where we have same values for g(t)

such as;

[-2,2]

A store has a 20% off sale on pants. The price of the pants before the discount was $48.

What was the sale price of the pants?

Answers

Answer:

$38.40

Step-by-step explanation:

20% of $48 is 9.60

48- 9.60= 38.40

Answer:

$38.40

Step-by-step explanation:

1. convert the percentage into a decimal by dividing x/100.

         20/100 =  0.2

2. multiply by the original price.

         0.2 * 48 = 9.6

3. subtract the discount.

         $48 - $9.60 = $38.40
