A cylindrical juice glass is 8 centimeters tall and has a radius of 3 centimeters. If the glass is full, which of the following is closest to the volume of the filled portion? A) 28 cm C) 170 cm B) 226 cm D) 98 cm PLEASE HELP!​

Answers

Answer:

226

Step-by-step explanation:

You first have to find the volume of the cylinder, which you would do 3 squared, which is 9, times 8, which is 72, and then times pi, which gives you 226.1946711. Since they want the closest volume to that number, it would just be 226. If you are confused on the equation, the equation for the volume of a cylinder looks like this:  [tex]V=\pi(r^{2})(h) \\[/tex], where r is the radius and h is the height.

Select all the equations that are equivalent. 52 = 8n + 4 4(2n + 1) = 52 4 = 52 – 8n 4n = 48 n = 6

Answers

Answer:

52 = 8n + 4

4(2n + 1) = 52

4 = 52 – 8n

n = 6

Step-by-step explanation:

52 = 8n + 4

52 - 4 = 8n

48 = 8n

n = 48/8

n = 6

4(2n + 1) = 52

8n + 4 = 52

8n = 52 - 4

8n = 48

n = 48/8

n = 6

4 = 52 – 8n

4 - 52 = -8n

-48 = -8n

n = -48/-8

n = 6

4n = 48

n = 48/4

n =12

n = 6

52 = 8n + 4 is equivalent to 4(2n + 1) = 52 is equivalent to 4 = 52 – 8n is equivalent to n = 6

Gabby has $1,506 in a savings account that pays 2.5% simple interest. How much interest will she earn in 3 years?

Answers

Answer:

$112.95

Step-by-step explanation:

Use the simple interest formula, I = prt

Plug in the initial amount, interest rate, and number of years

I = prt

I = (1506)(0.025)(3)

I = 112.95

So, the interest created in 3 years is $112.95

I = PRT ; P=$1506 , R=2.5% , T=3 years

I = (1506)(.025)(3)
I = 37.65 (3)
I = $112.95

If you can help me, I would be very happy.

Stephanie is earning simple interest of 3.5% on her money each month. She currently has $1325 in her account. What will her balance be in 5 months?

Answers

Answer:

$1556.88

Step-by-step explanation:

Since Stephanie is earning simple interest and not compound interest, we can multiply her interest rate for each month by how many months we are calculating for.

0.035 x 5 = 0.175

Then multiply that by her current balance but change the 0 in front of the 0.175 to a 1 to reduce the number of steps we have to take. (It automatically adds what is earned in interest to her current balance.)

1.175 x 1325 = 1556.875

For Exercises 1 and 2, write and solve an equation to find each missing length. Round to the nearest tenth if necessary. An observer is standing 30 feet from a flagpole. She is looking at the top of the flagpole. How tall is the flagpole? Round to the nearest tenth if necessary.

Answers

Answer:

21.65 feets

Step-by-step explanation:

First we obtain the angle of elevation :

Using Pythagoras rule :

Cosθ = adjacent / hypotenus

Cos θ = 30 / 37

θ = cos^-1(30/37)

θ = 35.82°

Hence, height of flagpole :

Sin θ = opposite / hypotenus

Sin θ = x / 37

Sin(35.82) = x / 37

0.5853083 * 37 = x

x = 21.65 feets

Height of flagpole = 21.65 feets

Tremaine scored 54 three-point goals, 84 two-point field goals, and 106 free throws in 23 games. How many points did he score on average per game

Answers

Answer: 18.96

Step-by-step explanation:

From the question, Tremaine scored 54 three-point goals, 84 two-point field goals, and 106 free throws. The total point scored will be:

=(54 × 3) + (84 × 2) + (106 × 1)

= 162 + 168 + 106

= 436 points

The number of points scored on average per game will then be:

= 436 / 23

= 18.96 points per game
