Answer:
15 percent of 90 hours = 13.5 hours
What is 15% of 90?
Y is 15% of 90
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 15% * 90
Converting percent to decimal:
p = 15%/100 = 0.15
Y = 0.15 * 90
Y = 13.5

Answer:
176.625 sq.ft, 4.8 sq.ft
Step-by-step explanation:
Area of circle=πr^2 or πd^2/4
11. Given,
d=15 ft
Now,
Area=πd^2/4
3.14*15^2/4
176.625 ft^2
Therefore, the area approximation is 176.6 sq.ft
12.
Given,
d=3.5 ft
Now,
Area= πd^2/8
3.14*3.5^2/8
4.8 sq.ft
I got the answer by dividing the area of circle by 2 as semicircle is half of circle.
Answer:
the answer is 2
Step-by-step explanation:
Answer: his weekly allowance is $8
The model to solve the problem is
X/2+8=12
Step-by-step explanation:
To get Eduardo's weekly allowance
Say it is x
Now he spent half of x on clothes and earns extra $8 more to end up with $12
Therefore
x/2+8=12
x/2=12-8
x/2=4
x=8
