Help Me Answer Question 8a And B, And Ill Give U 10 Points Lol

Answers

Answer 1

Answer:

Step-by-step explanation:

Find h when v = 20 and r = 3

Putting values in the formula

20 = (3.14)(3)2h

20 = (3.14)(9)h

20 = 28.26h

20/28.26 = h

R when v = 100 and h = 5

100 = (3.14)r2(5)

100/5 = 3.14r2

20 = 3.14r2

20/3.14 = r2

6.36 = r2

Square root on both sides

2.52 = r

If a town with a population of 500 doubles in size every 80 years, what will the population be 160 years from now?

Answers

Answer: 2000

Step-by-step explanation:

From the information, we are informed that a population of 500 doubles in size every 80 years. Therefore, the population in 160 years will have doubled twice i.e 160/80 = 2 times

First time doubling = 500 × 2 = 1000

Second time doubling = 1000 × 2 = 2000

Problem #3
The velocity (v) of an object is equal to its initial velocity (vo) plus the product of its acceleration
(a) and the elapsed time (1). write an equation that expresses time in terms of the other variables.

Answers

Answer:

[tex]\displaystyle t=\frac{v-v_o}{a}[/tex]

Step-by-step explanation:

Equations

It's given that the velocity (v) of an object is equal to its initial velocity (vo) plus the product of its acceleration (a) and the elapsed time (t).

The equation that expresses the above relationship is

[tex]v =v_o+at[/tex]

We must write an equation that expresses time in terms of the rest of the variables given above.

Swap the equation:

[tex]v_o+at=v[/tex]

Subtract vo:

[tex]at=v-v_o[/tex]

Divide by a:

[tex]\boxed{\displaystyle t=\frac{v-v_o}{a}}[/tex]

How many multiples of 5 are there in between 100 and 300?

Answers

Answer:

39 multiples

Step-by-step explanation:

Consider AP:

105, 110, ..., 295

As multiples of 5 between 100 and 300

The first term is 105, the common difference is 5, the last term is 295.

Use the nth term formula:

105 + 5(n - 1) = 2955(n - 1) = 190n - 1 = 190/5n - 1 = 38n = 39

Answer:

Solution given:

first term [a]=100

last term[l]=300

common difference [d]=5

second term[b]=100+5=105

now

we have

l=a+(n-1)d

substituting value

300=100+(n-1)5

300-100=(n-1)5

200/5=n-1

40=n-1

n=40+1

there are 41 multiple in between 100 and 300/including it but no including its 41-2=39 multiple

Madison saves 40% of all that she earns for washing cars. So far she has saved $72. How much has she earned in all?

Milan bought a table for Rs 3600. He sells it to Kirtim at a profit of Rs 205. Kritim sells it at
Rs 4968 to Aayush. Find the percentage profit of Kritim.

Answers

Answer:

23.41%

Step-by-step explanation:

Kirtim's purchase price was 3600 + 205 = 3805,

Kirtim sold the table for 4968 for a profit of 4968 - 3805 = 1163

Assuming requirement is for profit on revenue, so

P = 100 * (1163/4968) = 23.41%

A three foot long deli sandwich must be split into three pieces so that the middle piece is twice as long as the shortest piece, and the shortest piece is 8 inches shorter than the longest piece. How long should the three pieces be?

Answers

Answer:

Step-by-step explanation:

Let us represent:

Short pieces = x

Middle pieces = y

Long pieces = z

A three foot long deli sandwich must be split into three pieces

x + y + z = 3

The middle piece is twice as long as the shortest piece

y = 2x

The shortest piece is 8 inches shorter than the longest piece.

x = z - 8

z = x + 8

We substitute

x + y + z = 3

x + 2x + x + 8 = 3

5x = 8 - 3

5x = 5

x = 5/5

x = 1

y = 2x

y = 2 × 1

y = 2

z = x + 8

z = 1 + 8

z = 7

How long should the three pieces be?

Answer:

Option (3)

Step-by-step explanation:

Formula to calculate the surface area of a cardboard box in the shape of a cube is,

Surface area = 6(Side)²

If the length of the each side of the box is = 3 feet

Surface area of the cube = 6(3)²

                                          = 6 × 9

                                           = 54 square feet

Therefore, Surface area of the box in the shape of a cube is 54 square feet.

Option (3) is the correct option.
