I am not 100% positive but I think it is 4117.66
Answer:
A. y(3) + x = total cost
B. Shoe rental is $2.
Step-by-step explanation:
A. 4(3) + 2 = 14
B. If 4(3) = 12, and the total cost is $14. Then the shoes cost $2.
4(3) = 12 + 2 = 14
63+12x<15
12x<-48 (subtract 63 from both sides)
x<-4 (divide out the 12)
Answer:
x = 21.013155617496
Step-by-step explanation:
we have a right triangle then ,
Then
Then
x ≈ 21
Answer:
<em>97.5 sq. ft.</em>
Step-by-step explanation:
Im presuming the question asks to find area of the shaded region.
First of all, the total figure is a rectangle. We can write an expression(in words) for the shaded area.
<em>Shaded Area = Area of Rectangle - Area of Small Triangle(White) - Area of Large Triangle(White)</em>
Now, we find respective areas.
Area of rectangle:
length * width = (5+10) * (12) = 15 * 12 = 180
Area of Small Triangle (white):
A = (1/2) * base * height = (1/2) * 5 * (12-3) = (1/2) * 5 * 9 = 22.5
Area of Large Triangle (white):
A = (1/2) * base * height = (1/2) * 10 * (12) = 60
Now, we find area of shaded region:
<em>Shaded Area = Area of Rectangle - Area of Small Triangle(White) - Area of Large Triangle(White)</em>
<em>Shaded Area = 180 - 22.5 - 60 = 97.5 sq. ft.</em>
