The sum of a rational number and irrational number is irrational.

a round swimming pool has a circumference of 66 feet. Carlos wants to buy a rope to put across the diameter of the pool. the rop

Answer:

$11.25
21 ft

Step-by-step explanation:

The formula for the circumference of a circle in terms of diameter is ...

C = πd

Then the diameter is ...

d = C/π

If we use π ≈ 22/7 and C = 66 ft, then we find the diameter to be ...

d = (66 ft)/(22/7) = (66 ft)(7/22) = 21 ft

The diameter of the pool is about 21 feet.

__

Since Carlos needs 4 more feet of rope, he will want to buy 25 feet of rope for a cost of ...

(25 ft)($0.45 /ft) = $11.25

Carlos will pay $11.25 for the rope.

Solve for x if x+3.5=4 1/3

WARRIOR [948]

Answer:

x = 5/6

Step-by-step explanation:

x + 3 1/2 = 4 1/3 (converting decimal to fraction)

x + 3 3/6 = 4 2/6 (creating common denominators)

x = 5/6 (removing 3 3/6 from both sides)

If my answer is incorrect, pls correct me!

!!!!!!!!!I AM CRYINGGGG!!!!!! PLZZZZ

andrey2020 [161]

Answer:

-x^2-2x-3

Step-by-step explanation:

Question 1: Just substitute in the values of f(x) and g(x) and simplify!

f(x) - g(x) = 4x^2-5x+3-(5x^2-3x+6)
f(x)-g(x) = 4x^2-5x+3-5x^2+3x-6
f(x)-g(x) = -x^2-2x-3

Tell me if this helps, and if you still need number 2 or if you can do it by yourself! (Hint: substituting also plays a role in question number 2.)

Hope this helps!!

The plan for the Thorne’s backyard play area, shaped like a trapezoid, is shown. The area of the play area is 286.56 square feet

lorasvet [3.4K]

The length of material needed for the border is the perimeter of the backyard play area

<h3>How to calculate the length of material needed </h3>

The area of the play area is given as:

$Area = 286.56$

The area of a trapezoid is calculated using:

$Area = 0.5 * (L1 + L2) * H$

Where L1 and L2, are the parallel sides of the trapezoid and H represents the height.

The given parameter is not enough to solve the length of material needed.

So, we make use of the following assumed values.

Assume that the parallel sides are: 25 feet and 31 feet long, respectively.

While the other sides are 10.2 feet and 8.2 feet

The length of material needed would be the sum of the above lengths.

So, we have:

$Length = 25 + 31 + 10.2 + 8.2$

$Length = 74.4$

Using the assumed values, the length of material needed for the border is 74.4 feet
