Answers

Answer:

$292.50

Step-by-step explanation:

Equation - A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 2.5%/100 = 0.025 per year.

Solving our equation:

A = 260(1 + (0.025 × 5)) = 292.5

A = $292.50

The total amount accrued, principal plus interest, from simple interest on a principal of $260.00 at a rate of 2.5% per year for 5 years is $292.50.

Your Answer Should Be: A=$292.50

A cylindrical shaped swimming pool has a diameter of 30 feet and a water height of 4.5 feet. How many cubic feet of water is contained in the pool? Use 3.14 for pi. Round your answer to the nearest cubic foot.

Answers

Answer:  A

Step-by-step explanation:

The question asks about how much space the cylinder can hold. That's how i know they are really asking for the volume of the cylinder.

Next, the volume of a cylinder is V= πr²h

R is the radius

h is the height

π= 3.14 (in this question).

We know that the diameter is 30, and that the radius is always 1/2 of the diameter. To find the radius, find 1/2 of 30. Whenever you see something of something, just turn the "of" into the multiplication sign. So just do 1/2 x 30= 15.

R= 15

H= 4.5

Pi= 3.14

Now we can plug into the formula:

Using pemdas, do exponents first. Then multiply from left to right.

V= πr²h

V= 3.14x15²x4.5

V= 3.14x225x4.5

V= 706.5x4.5

V= 3,179.25

3,179.25  rounds rounds to just 3,179 because first you round the .25 to point 3, and because 3 is under 5, it rounds down. The answer is A

PLS NO LINK thanks :)

Answers

Answer:

Step-by-step explanation:

here you go it in there

Answer:

Probability is 64%

Step-by-step explanation:

Given the smaller circle which is shaded whose radius is denoted by r and  the largest circle whose radius is denoted by R

                     r = 3 inches

                    R = 5 inches

Step 1 : To calculate the area of shaded region.

Area of circle =

⇒ Area =    

          =   square inches

Step 2 : To calculate the area of larger circle.

Area of circle =

⇒ Area =    

            =  square inches

Step 3 : Calculate the probability that a point chosen from shaded region

Probability = Area of shaded region/Area of larger circle.

                  =  /

                  =  

                  =  0.36 = 36%

Step 4 : calculate the probability that a point chosen inside the larger circle is not in shaded region.

Probability = 1 - 0.36

                  = 0.64 = 64%

Hence the probability is 64%

Answers

Answer:

Brainliest please

Step-by-step explanation:

Simplifying

3x + -1s = r

Reorder the terms:

-1s + 3x = r

Solving

-1s + 3x = r

Solving for variable 's'.

Move all terms containing s to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-1s + 3x + -3x = r + -3x

Combine like terms: 3x + -3x = 0

-1s + 0 = r + -3x

-1s = r + -3x

Divide each side by '-1'.

s = -1r + 3x

Simplifying

s = -1r + 3x
