Write the equation out: (total cost: 0.35C[per carton] + 75[delivery charge]) ≤ 500. Subtract 75 on both sides and it would be: 0.35C ≤ 425. Divide 0.35 on both sides and you'll get C ≤ 1214. Therefore, the maximum # of cartons that Elvira can buy is 1214 cartons of milk.

What is the m 52 40 45 54

lidiya [134]

Answer:

○ $\displaystyle 54°$

Step-by-step explanation:

Use the Triangular Interior Angles Theorem to figure this out:

180° = [3x]° + [2x]° + [5x]°

$\displaystyle \frac{180°}{10°} = \frac{[10x]°}{10°} \\ \\ 18 = x$

Plug this back into the m∠L to get 54°.

I am joyous to assist you anytime.

If y varies directly as the x^2 and y = 200 when x = 5, what is the value of y when x = -3?

gayaneshka [121]

As the variation is direct we have:
$y = kx ^ 2
$
We must find the value of k.
For this, we use the following data:
y = 200 when x = 5
Substituting values we have:
$200 = k5 ^ 2
$
Clearing k:
$k = 200/5 ^ 2

k = 200/25

k = 8$
Then, the function is:
$y = 8x ^ 2
$
We evaluate the function for x = -3
$y = 8 (-3) ^ 2

y = 8 (9)

y = 72$
Answer:
the value of y when x = -3 is:
c.
72
