Answer:
28+104 = 132cm^2
Step-by-step explanation:
We can find the area of this figure by breaking it into two separate pieces. The top is a rectangle and the bottom is a trapezoid.
A rectangle = l*w = 7*4 = 28 cm^2
A trapezoid = 1/2 (b1+b2) *h = 1/2 (19+7) *8 = 1/2 (26)*8 =104 cm^2
Add these areas together
28+104 = 132cm^2
Answer:
wire left for square = 100 - (14+14+4+4) cm
= (100 - 36) cm
= 64 cm
so
side of square = 64/4 = 16 cm
Answer: 7.25 gallons
Step-by-step explanation:
Convert 13¹/₂ to a whole number with a decimal:
= 1/2 = 0.5
= 13.5 gallons of gas
If the gas reduces by 6.25 gallons, the amount of gas remaining will be:
= Starting amount - Amount reduced by
= 13.5 - 6.25
= 7.25 gallons
Answer:
v = 6
Step-by-step explanation:
3/v = 2/4
We can use cross products to solve
2v = 3*4
2v = 12
Divide each side by 2
2v/2 = 12/2
v =6
