A donut shop bakes 4 dozen donuts every 18 minutes. Find the average rate to the nearest hundredth.

Veseljchak [2.6K]

Answer: 2.67 donut/minute
To find the average rate, you need to know the donut production and the time needed. In this question, the unit used is dozen donut and minutes. Assuming you want the rate to have donut/minute then the calculation would be:

Rate:
4x12 donuts / 18 minute
48 donut /18 minute
2.67 donut/minute

What is the value of 7 ^−3 ^ −1 for = −2 and = 4?

andrey2020 [161]

Answer:

d. −7/32

Step-by-step explanation:

The expression that we have to evaluate in this problem is:

$7x^{-3}y^{-1}$

We have to evaluate this expression for:

x = -2

y = 4

We start by rewriting the expression by rewriting it using the following:

$a^{-n}=\frac{1}{a^n}$

So the expression can be rewritten as

$7x^{-3}y^{-1}=\frac{7}{x^3 y}$

Now we observe that:

$(-2)^3=(-2)(-2)(-2)=-8$

Therefore, by substituting x = -2 and y = 4 into the expression, we find:

$\frac{7}{(-2)^3\cdot 4}=\frac{7}{-8\cdot 4}=-\frac{7}{32}$
