PLZ HURRY ITS TIMEDDD

Dafna11 [192]

Answer:

Option C. 4(20-16y): Each side measures 20-16y units.

Step-by-step explanation:

we know that

The perimeter of a square is equal to

$P=4b$

where

b is the length side of the square

we have

$P=(80-64y)\ units$

substitute the given value in the formula

$(80-64y)=4b$

solve for b

Divide by 4 both sides

$(20-16y)=b$

Rewrite the expression

$b=(20-16y)\ units$

Alternative Method

we have

$P=(80-64y)\ units$

Factor 4

$P=4(20-16y)\ units$

Each side measures (20-16y) units.

In the smoky mountains of Tennessee, the percent of moisture that falls as snow rather than rain is approximated by P = 10.0 ln

Mars2501 [29]

Answer:

A. About 4,900 ft

Step-by-step explanation:

We want h such that ...

5 = 10·ln(h) -80

8.5 = ln(h) . . . . . . . add 80, divide by 10

e^8.5 = h ≈ 4914.8 . . . . take the antilog

h ≈ 4900 . . . . feet
