Answer: no ten times is not smaller then 100
Step-by-step explanation:
The radius is √25=5 in this case.
find the area of each triangles first. (the pentagon can be divided into 5 isosceles triangles)
the two equal sides are 5 each, the angle between them is 360/5=72 degree, so the base side is 2*5*sin36, and the height is 5*Cos36
the area of each triangle is (1/2)*2*5*Sin36*5*Cos36
the total area of the 5 triangles is: 5*(1/2)*2*5*Sin36*5*Cos36
use a calculator: A≈59.44
Answer:
x=2
Step-by-step explanation:
5x-7=5-x
5x=12-x
6x=12
x=2
Answer:
12
Step-by-step explanation:
divide 110 by 9 and the answer is 12.2, since 2 is below 5 you round back to the nearest whole number and you'll receive 12.
One cubic foot of sand should be $11.25. You can find this answer by dividing the first price by 3, because there are 3 feet in a yard.
