<h2>Answer:</h2>

4.82 × 10⁻⁴

<h3>Explanation:</h3>

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

A triangular frame has sides that measure 15'-7",20'-4" and 26'-2". What is the total length of three sides?

tatuchka [14]

we know that

$1\ foot=12\ inches$

$1'=12"$

<u>Part 1) </u>

we know that

side 1=15'-7"

side 2=20'-4"

side 3=26'-2"

To find the total length of three sides sum the three sides

so

total length=side 1+side 2 +side 3

substitute

total length=15'-7"+20'-4"+26'-2"

total length=(15'+20'+26')+(7"+4"+2")

total length=(61')+(13")

remember that

12"=1'

13"=12"+1"=1'+1"

substitute

total length=(61')+(1'+1")

total length=(62')+(1")---------> 62'-1"

therefore

<u>the answer is</u>

the total length of three sides is 62'-1"

PLEASE HELP PLA

aleksley [76]

Answer:

$y = -x+8$

Step-by-step explanation:

The side that is parallel to BC is EF

Find the slope of EF:

$m = \frac{2-4}{6-4} =\frac{-2}{-2} =-1$

Easiest way is just put the formula in point-slope form and simplify.

Let's use point F, which is (6,2)

$y -2=-(x-6)$

Simplify:

$y-2=-x+6$

Add 2 on both sides:

$y = -x+8$

Hope this helped

Answer:

B) 77.5 square feet

Step-by-step explanation:

cut shape into rectangle and triangle

area of rectangle = x*y

area of rectangle = 5*13

area of rectangle = 65

area of triangle = (z-x)*(y-w)/2

area of triangle = 5*3/2

area of triangle = 7.5

Total area = 65 + 7.5

Total area = 77.5, B)
