Nevaeh is going to invest in an account paying an interest rate of 4.6%
compounded quarterly. How much would Nevaeh need to invest, to the
nearest cent, for the value of the account to reach $125,000 in 9 years?

Answers

$24,761.07

This is because we do $125000/1.046^36
As the interest rate 4.6% added to the original 100% is 104.6% or 1.046
The power is 36 as it is compounded 36 times as 9 years, 4 times a year

Yani is creating a mural on a patio that measures 3 m long by 2 m wide. He is using 1 cm by 1 cm tiles. How many tiles will he need to use for the mural to cover the whole patio?

Answers

Answer: 60,000 tiles

Step-by-step explanation:

First find the area of the mural.

= 3 * 2

= 6 m²

The find the area of the tiles.

= 1 * 1

= 1 cm²

I m² = 10,000 cm²

There is therefore:

= 6 * 10,000

= 60,000 cm²

That is the area that needs to be covered in cm²

Seeing as each tile is 1cm², the number of tiles needed is:

= 60,000 / 1

= 60,000 tiles

Answer: the answer is 60,000 tiles

by the way that kinda seems like a lot of tiles to place like how long is that gonna take.

He measures and determines that he needs 24 feet of fencing. When he arrives at home improvement store, he realized fencing is priced at $0.25 per inch how much will it cost to fence it

Answers

Answer:

It will cost 72 dollars to fence the perimeter

Step-by-step explanation:

First of all, we will have to make sure that we are working with the same units.

To do this, we will have to convert our units which are given in feet to inches.

1 foot = 12 inches

24 feet = 288 inches.

We now have the total length of what he needs to be 288 inches.

The fence costs 0.25 dollars per inch.

Therefore 288 inches will cost 0.25 X 288 = $ 72

Joe uses 2 1/4 yards of yellow ribbon to make a bow

Answers

Answer:

11 and 1/4 yards of ribbon

Step-by-step explanation:

Hope this helps you! :)

Answer:

11 1/4 or 11.25 yards

Step-by-step explanation:

He uses 2 1/4 yards for 1 bow

Multiply 2 1/4 by 5

2 1/4 = 9/4

5 = 5/1

9/4 x 5/1

9x5 = 45 , 4x1 = 4

45/4, now divide 45 by 4

you get 11 1/4 same as 11.25 yards to make 5 bows

The circumference of a circle is approximately 3.14 times the length of its diameter. Which inequality can be used to find all possible diameter lengths, d, if the circumference of a circle is more than 50 cm? 3.14 d less-than 50 3.14 d greater-than 50 50 d greater-than 3.14 50 d less-than 3.14

Answers

Answer:

3.14 d greater-than 50

(i also need help with one of my questions >~<)

Step-by-step explanation:

Since the circumference of a circle is approximately 3.14 times the length of its diameter, mathematically speaking:

C = 3.14d  

That expression must be greater (>) than 50:

3.14 d > 50

So, the correct option is; 3.14 d greater-than 50

A rectangle has a perimeter of 56 cm and an area of 96cm^2. Its length is 4 more than five times its width. What is the lenght and width of the rectangle?

Answers

Answer:

L= 24cm

W= 4cm

Step-by-step explanation:

Given data

Perimeter= 56cm

Area= 96cm^2

Let the width be x

W= x cm

L= 5x+4

P=2L+2W

56= 2(5x+4)+2x

56= 10x+8+2x

56-8= 12x

48= 12x

x= 48/12

x= 4cm

L= 5x+4

L= 5(4)+4

L= 20+4

L= 24cm

Is there a linear relationship between height and volume? Explain how you know.

Answers

Answer:

Yes

Step-by-step explanation:

The volume is for example the area of a circle times the height. If you divide the volume of a cylinder by the amount the radius is squared multiplied by pi, to calculate its height.

Yes, there exists a linear relationship between the height and the volume.

What is a linear relationship?

A linear relationship is a relationship between the variables in a linear fashion. The relations ships can positive, negative, and neutral. Volume is a scalar quantity that is expressed in three-dimensional space.

Example of volume for the area of a circle is times the height. If we divide the volume of a cylinder by the amount of R it can be squared and multiplied by pi, to find its height.

Find out more information about the volume.
