Area of the sign ( trapezoid ) :
A = ( a + b ) / 2 · h
where: a = 8, b = 5, h = 5
A = ( 8 + 6 ) / 2 · 5 =
= 14/2 · 5 = 7 · 5 = 35 ft²
Answer:
B ) 35 square feet
Answer:
Angle C = 142 degrees
Step-by-step explanation:
A+B = 90
B+C = 180
Rearrange first equation to get B = 90-A
Plug this into the second equation:
90-A + C = 180
C = A + 90
Plug in A, C = 52 + 90 = 142
Answer:
The vehicle covers 126 miles on 7 gallons of fuel.
Step-by-step explanation:
Given:
The distance traveled is directly proportional to the amount of fuel.
For
gallons of fuel distance traveled
miles can be given as:
∝ 

where
is constant of proportionality.
The vehicle covers
miles on
gallons.
So

Dividing both sides by 5.


∴ 
When
gallons

miles
∴ The vehicle covers 126 miles on 7 gallons of fuel.
Answer:
39 units by 51 units
Step-by-step explanation:
The painting is a scale factor of 1/3, so each side length is 1/3 of the original. To find the original multiply both side lengths by 3.
13x3 = 39
17 x 3 = 51
