6% OF 56% X 60% X 40%

Answers

Answer:

Step-by-step explanation:

6% of 56 is 10.71

6% of 60 is 10

6% of 15

hopefully this answers your question

6% of 56 is 10.71

6% of 60 is 10

6% of 15

After this, I think you may want to multiply 10.71, 10, and 15. Unless you were trying to separate all the numbers. If you weren't, its 1606.5!

Write an equation of the line that passes through 9,2 and is parallel to the line y=5/3x+9

Answers

Answer:

Equation: I believe its y=5/3x-13

Step-by-step explanation:

In the "y=5/3x+9" equation, 5/3 is the slope. You then take the slope (5/3) and the points (9,2) and add it to the equation "y+y1=m(x-x1)":

y-y1=m(x-x1)

distribute 5/3: y-2=5/3(x-9)

y-2=5/3x-45/3

y-2=5/3x-15

-add 2 on both sides-

y=5/3x-13

I might be wrong- but its worth a try ;-;

Step-by-step explanation:

The formula for the volume of a sphere is ...

  V = 4/3πr^3

A sphere with a diameter of 20 yards has a radius of 10 yards, so its volume is ...

  V = 4/3π(10 yd)^3 = 4000π/3 yd^3 ≈ 4188.79 yd^3

Rounded to tenths, that's approximately 4188.8 yd^3.

Finishing off the sentences below in the pic:

The area of each circle is exactly 2.25 pi square inches.

(As the area of a circle is: Area = pi x radius^2).
Therefore the area is: 1.5^2 x pi
Area: 2.25pi


There are TWO identical circles in the cylinder.

(Think of a cylinder and recall that a cylinder has a circle on the top and bottom of the 3-D shape, therefore a cylinder has two identical circles)


So the total area of all the circles is 4.5pi square inches.

(Adding the area of the two identical circles together, where 2.25pi + 2.25pi = 4.5pi)
