Answer:

129 square foot

Step-by-step explanation:

<u>Step 1: Convert height of the door to inches</u>

Height of the door = 10 feet 8 inches

1 feet = 12 inches

10 feet = y inches

<em>Cross Multiply</em>

y = 120 inches

Height of door in inches = 120 + 8 =128 inches

<u>Step 2: Find the surface area of one side of the door</u>

Surface area = length x width

length = 128 inches

width = 145 inches

Surface area = 128 x 145

Surface area = 18560 inches

<u>Step 3: Convert surface area from inches to square foot</u>

Surface area = 18560 inches

1 square foot = 144 inches

         y           = 18560 inches

<em>Cross multiply</em>

144y = 18560

y = 18560/144

y = 128.89 rounded off to 129 square foot.

Therefore, you should report 129 square foot surface area to the hardware store.

The sum of three numbers is 8. The third is 9
Ierofanga [76]

Answer:

→<u> </u><u>First</u><u> </u><u>value</u><u> </u><u>is</u><u> </u><u>1</u>

→<u> </u><u>Second</u><u> </u><u>value</u><u> </u><u>is</u><u> </u><u>2</u>

→<u> </u><u>Third</u><u> </u><u>value</u><u> </u><u>is</u><u> </u><u>5</u>

Step-by-step explanation:

• let numbers be x, y and z

{ \tt{z = 8y - 9 -  -  - (eqn \: 1)}} \\  \\ { \tt{10x = 8y - 7 -  -  - (eqn \: 2)}} \\  \\ { \tt{x + y + z = 8 -  -  - (eqn \: 3)}}

• from eqn 2, make x the subject:

{ \tt{x =  \frac{8y - 7}{10} }} \\

• substitute all variables in eqn 3:

{ \tt{ \frac{8y - 7}{10}  + y + 8y - 9 = 8}} \\  \\ { \tt{8y - 7 + 10y + 80y - 90 = 80}} \\  \\ { \tt{98y = 177}} \\  \\ { \boxed{ \tt{ \: y = 1.8}}}

• find z

{ \tt{z = 8y - 9}} \\  \\ { \tt{z = 8(1.8) - 9}} \\  \\ { \tt{z = 14.4 - 9}} \\  \\ { \boxed{ \tt{ \: z = 5.4 \: }}}

• find x:

{ \tt{x =  \frac{8(1.8) - 7}{10} }} \\  \\ { \tt{x =  \frac{7.4}{10} }} \\  \\ { \boxed{ \tt{ \: x = 0.74 \: }}}

Rounding to nearest value:

{ \boxed{ \rm{x = 1}}} \\ { \boxed{ \rm{y =2 }}} \\ { \boxed{  \rm{z = 5}}}
