Answer

$\boxed {d= \frac{19}{3}}$

Solution

Simplify both sides of the equation.

$\frac{7}{3} + \frac{-7}{3}$

We are left with d = 4+ $\frac{7}{3}$

Add

$\frac{12}{3}+\frac{7}{3} =\frac{19}{3}$

Hence, d = $\frac{19}{3}$

Ellis is painting wooden fenceposts before putting them in his yard. They are each 5 feet tall and have a diameter of 1 foot. Th

Naya [18.7K]

Answer:

39.25 cubic feet of paint will be needed by Ellis.

Step-by-step explanation:

Volume of a cylinder:

The volume of a cylinder of radius r and height h is given by:

$V = \pi r^2h = 3.14r^2h$

How much paint will Ellis need to paint all the surfaces of the 10 fenceposts?

This is the combined volume of these 10 fenceposts.

They are each 5 feet tall and have a diameter of 1 foot.

Radius is half the diameter, so $r = \frac{1}{2} = 0.5$ . Also $h = 5$

10 fenceposts:

Each has the same volume, so:

$V = 10(3.14)r^2h = 31.4(0.5)^2(5) = 39.25$

39.25 cubic feet of paint will be needed by Ellis.

The ratio of dogs to cats in a park is 10 to 9. If there are 50 dogs then how many cats are there

serious [3.7K]

Knowing the ratio for dogs to cats is 10:9

To get to 50 dogs they multiplied 10x5

So multiply 9x5 as well to get the number of cats

Cats = 45

A circular garden with a radius of 8 feet is surrounded by a circular path with a width of 3 feet.

Vladimir [108]

Answer:

178.98 ft2

Step-by-step explanation:

we know that

The area of the circular path alone is equal to subtract the area of the circular garden from the area of the complete circle (circular garden plus circular path)

$A=\pi (r_2^2-r_1^2)$
