Mr.Williams' class built this platform for a school event. They also built a model of the platform in which 1 foot was represented by 2 inches. What is the volume of the platform? What is the volume of the model?

Answers

Answer 1

Answer:
For every 1ft in the original, the model used 2in

1ft:2in

There are 12inches in a foot, so we could also write the ratio as

12in:2in

12/2=6 So the model is 6X smaller than the original

The length of the original was 9ft

L=9ft

The width of the original was 4ft

W=4ft

The height of the original is 6ft

H=6ft

The volume of the original is:
V=L*W*H
V=9*6*4=216ft³

Now lets find the dimensions of the model...

If the length of the original was 9 feet we just divide that number by 6 to find the length of the model.

9/6= 1 1/3 ft

The length of the model is 1 1/3ft or 16in

If the width of the original was 4 feet we just divide that number by 6 to find the width of the model.

4/6= 2/3 ft

The width of the model is 2/3ft or 8in

If the height of the original was 6 feet we just divide that number by 6 to find the height of the model.

6/6=1ft

The height of the model is 1ft or 12 inches

The volume of the model is...

V=l*w*h=16in*8in*12in=1536in³

Answer:

D. offer possible answers to historical questions.

Step-by-step explanation:

An argument is a statement which a historian proposes. In order to back up the statement the historian provides proof. The argument is then read by other historians and the proof is analyzed. After the analysis if other historians come to the same conclusion which the statement points to then the argument is accepted.

So, this is the way to offer possible answers to historical questions.

This is because they want to make sure their possible answers are correct, reliable and accurate.

A: around 32 to 33 men, using proportions I know that .65 of the people surveyed were men making it 130 men. Out of those 130, .25 like to play sports, so I multiplied 130x.25 to get 32.5 men, however we can’t can’t have half a male right?!

B. If 200 people were surveyed, men and women, .10+.15/ .25 of those people like reading... so I multiplied 200x.25 to get 50. Meaning 50 people like reading.

C. If we know 130 men were surveyed then we’d subtract that amount from 200 which is the overall amount of people to get the amount of women surveyed which is 70.

4 percent of a number is what fraction of that number??

Carl puts $1.10 in his penny bank every day in the month of July (31 days) his total saving was 55.00 at the end of June. What’s the best estimate for Carl’s savings at the end of July

Answers

He saves $1.10 everyday in July.

So he will have ($1.10 x 31) = $34.10 saved in July.

His total savings will be ($34.10 + 55)

Hence he will have a total of $89.10 at the end of July.

ANSWER:
He will have $89.10 at the end of July.

You will need to find how much he got on July so you will need to multiply 1.10 and 31.

1.10 time 31 is 34.1

Then subtract 55-34.1=20.9

Answer:20.9
