Given the following expressions:

Tamiku [17]

Step-by-step explanation:

Step 1:

A . 5 with an exponent of 3 times 5 with an exponent of -4

= $5^{3} * 5^{-4}$ = $5^{3-4}$ = $5^{-1}$ = 1/5

B . (1/4) with an exponent of 3 times (1/4) with an exponent of 2

= $(1/4)^{3} * (1/4)^{2} = (1/4)^{3+2} = (1/4)^{5} = 1/1024$

C. Same as above

D. $\\\frac{(-7)^{5} }{(-7)^{7} } = (-7)^{5-7} = (-7)^{-2} =1/7^{2} = 1/49$

Step 2 :

All the above expressions have a value between 1 and 2

Shipping rates for Company A and Company B are shown in the tables below. Which company has shipping rates that you can represen

meriva

Company B; the ratios of cost to weight are equivalent.

Step-by-step explanation:

Step 1:

In the equation, $y=kx$ k is the constant of proportionality.

If the values are in accordance with $y=kx$ , the values of k will be constant for all the values.

So we determine the values of k for both the companies and see which has a constant k.

If $y=kx, k = \frac{y}{x}$ . In these tables, y is the total cost and x is the weight in lbs.

Step 2:

For company A,

when $y=10.55, x=1, k = \frac{10.55}{1} = 10.55,$

when $y=10.85, x=2, k = \frac{10.85}{2} = 5.425,$

when $y=11.15, x=3, k = \frac{11.15}{3} = 3.71666.$

For company B,

when $y=2.75, x=1, k = \frac2.75}{1} = 2.75,$

when $y=5.50, x=2, k = \frac{5.50}{2} = 2.75,$

when $y=8.25, x=3, k = \frac{8.25}{3} = 2.75.$

So company B has a constant value of $k=2.75$ .

which choice shows 13⋅(7⋅4) correctly rewritten using the associative property and then correctly simplified? 13⋅4⋅7

Cloud [144]

The answer choice which represents the correctly rewritten form of the expression is; (13⋅7)⋅4.

<h3>Which answer choices represents the expression according to the associative property?</h3>

It follows from the task content that tee expression given is; 13⋅(7⋅4).

However, it follows from the associative property of multiplication and addition is such that the equivalent expression can be rewritten as;

(13⋅7)⋅4.
