Mrs. Hernandez is redesigning her craft room which is in the shape of a rectangular prism. She wants to add wainscoting, which is a wood wall covering, from the floor to halfway up the walls. There are two doors that are each 3 feet wide. How many square feet of wainscoting will she need to cover the space?

Answers

Answer 1

Answer:

312

Step-by-step explanation:

T.S.A : ( 2 × L × w ) + ( 2 × h × w ) + ( 2 × L × h ) = Area

9 - 3 = 6 - 3 = 3

( 2 × 12 × 3 ) + ( 2 × 8 × 3 ) + ( 2 × 12 × 8 ) = Area

72 + 48 + 192 = 312

A cylinder has a radius of 4.5 inches and a height of 15 inches. If the radius is doubled, how would it affect the original volume of the cylinder?

Answers

Answer:

The volume will be increased 4 times.

Step-by-step explanation:

Short mathy expl:

If the radius is "doubled" that is 2 times bigger. But in the volume formula, the radius is squared. So 2 times bigger AND squared makes it FOUR times bigger.

See the volume calculations:

original--

Vol = pi•r^2•h

= (3.14)•4.5^2•15

= 953.775

new/bigger radius--

Vol = 3.14•9^2•15

= 3815.1

So when the radius is doubled, going from 4.5 to 9, the volume goes from 953.775 to 3815.1

3815.1 is 4 times 953.775

Find the sum of the first 8 terms of the following series, to the nearest integer 48,60,75

Answers

The series is a geometric series and the sum of the first 8 terms of the series 48, 60, 75 is 952.32

How to determine the sum of the first 8 terms?

The series is given as:

48, 60, 75

The above series is a geometric series with the following parameters:

First term, a = 48

Common ratio, r = 1.25

The sum of n terms is:

[tex]S_n = \frac{a(r^n - 1)}{r -1}[/tex]

So, we have:

[tex]S_8 = \frac{48 * (1.25^8 - 1)}{1.25 -1}[/tex]

Evaluate

[tex]S_8 = 952.32[/tex]

Hence, the sum of the first 8 terms of the series is 952.32

Okay so your numbers are:

0, 2, 2, 4, 5, 1, 3, 4, 2, 4, 5, 0, 0, 1, 3, 4

You have to put them in order first:

0, 0, 0, 1, 1, 2, 2, 2, 3, 3, 4, 4, 4, 4, 5, 5

Now that its all in order you have to pull out the middle number.

Since there are 16 numbers its an even pile so you have to get the 2 middle numbers:

2, 3

Add them both together:

2 + 3 = 5

Then divide by 2:

5 ÷ 2

= 2.5

The amount of the money after 7 years with a rate of 13% with an initial amount of $400 will be $ 941.04.

What is compound interest?

Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.

Tanvi opened a savings account and deposited $400.00 as principal.

The account earns 13% interest, compounded annually.

Then the balance after 7 years will be

We know the compound interest formula.

A = P (1 + r)ⁿ

We have

P = $ 400

r = 13%

n = 7 years

Then we have

A = 400 x (1 + 0.13)⁷

A = 400 x 1.13⁷

A = 400 x 2.3526

A = $ 941.04
