a 12 foot tall building casts on 8 foot long long shadow. how long of a shadow will a 5 foot tall women have

Answers

This is just a basic proportion. 5/8 = x/12. So the 5 foot tall women would have a 7.5 foot shadow.
Final answer:

Using the concept of similar triangles and the given ratio of a building's height to its shadow, it was calculated that a 5-foot tall woman would cast a shadow that is approximately 3.33 feet long.

Explanation:

The question deals with similar triangles where the ratio of the height of an object to the length of its shadow is constant if the sun's rays are considered to be parallel. Given that a 12-foot tall building casts an 8-foot long shadow, we can use this ratio to determine the length of the shadow that a 5-foot tall woman will cast.

First, find the ratio of the building's height to its shadow's length:

Height of the building / Length of shadow = 12 feet / 8 feet = 1.5

Since the ratio should remain the same, we can set up a proportion for the woman:

Height of the woman / Length of her shadow = 5 feet / x (the unknown length of the shadow)

Now solve for 'x' using cross multiplication:

12 / 8 = 5 / x12*x = 5*8x = (5*8) / 12x = 40 / 12x = 3.33 feet (approximately)

Therefore, the shadow cast by the 5-foot tall woman will be approximately 3.33 feet long.

Round to the nearest ten thousand: 68,231

A. 69,000

B. 70,000

C. 68,000

D. 60,000

Answers

The number 68,231 is closer to 70,000 than it is to 60,000

So the answer is choice B

Another way to see this answer is to drop everything after the 6 (which is what is in the ten-thousands digit place) and replace all of those dropped digits with 0s. We add 1 to the digit we didn't get rid of because the 8 after the 6 is larger than 5
Hello there!

Your answer would be (68,00) because when rounding to the nearest 10th, we basically look at the tenth place.

6(8).

 Number 8 is the 10th place, and it is over 5 to pass to line.

It goes right back up.
Your answer would be the (option b)

A. 69,000 
B. 70,000 
C. 68,000 
D. 60,000

Answer:

5 is a constant. (it has no variables)

x + 2 is not a constant. It does, however, have two terms, x and 2.

This rules out a and b.

A pool pump fills 1/6 of the pool in 1/3 hour. How much of the pool is filled in one hour

Answers

1/2 way because to get to a full hour with 1/3 you have to multiply by three so you multiply 1/6 by 3 and get 3/6 which is simplified to 1/2. Hope I helped!
For this, we can just multiply 1/6 by 3 since you have to multiply 1/3 by 3 to get to one hour ( basically just adding 1/6 every 1/3 of an hour until the full hour).
1/6•3=3/6=1/2
So, half of the pool will be filled in one hour.

Kylie is on a swing the swing moves back and forth every 5 seconds. About how many minutes would it take Kylie to go back and forth one hundred times? Can you help me figure the minutes out in a fraction?

Answers

31/2 is what i got....its like 87% right

The fraction of the total time in minutes is therefore 8 1/3 minutes, which is equal to 25/3 minutes when expressed as an improper fraction.

To determine the amount of time it would take for Kylie to swing back and forth 100 times, we must first understand that the period of the swing, the time it takes to complete one full cycle back and forth, is 5 seconds. Therefore, we can calculate the total time for 100 swings by multiplying the period by the number of swings:

Total time (seconds) = Period (seconds per swing) * Number of swings

Total time (seconds) = 5 seconds/swing * 100 swings

Total time (seconds) = 500 seconds

To convert seconds into minutes, we divide by the number of seconds in a minute, which is 60:

Total time (minutes) = Total time (seconds) / 60 seconds/minute

Total time (minutes) = 500 seconds / 60 seconds/minute

Total time (minutes) = 50/6 or approximately 8 minutes and 20 seconds.

The fraction of the total time in minutes is therefore 8 1/3 minutes, which is equal to 25/3 minutes when expressed as an improper fraction.

at the park, 4/7 of the children are boys. if there are 8 boys at the park, how many are girls?

Answers

There are 4/7 boys, so there are 3/7 girls.

Let the total number of children be x.

4/7x = 8
1/7x = 8 ÷ 4
1/7x = 2
3/7x = 2 x 3
3/7x = 6

There are 6 girls.
6 because 4/7 boys means a ratio of 4:3, so twice 4 to make 8 means twice 3 to make 6.

You had $50. You spent 10% of the money on clothes, 20% on games, and the rest on books. How much was spent inborn books?

Answers

Answer:

$35 was spent on books

Step-by-step explanation:

We must figure out the percent out of $50 that the books are worth

This is 70%

Now we need to figure out how much 10% is out of $50

50 divided by 10

10 percent of the books is 5 dollars

Now to find 20% we do 5+5=10 because it is just x2 of 10%

So we have spent 15 dollars on clothes and games

So now all we must do is 50-15=35

This is how we get our answer!

Pls mark me brainliest! Hope this helps :D

After spending 10% on clothes 20% on games I spent $35 on books.

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, You had $50. You spent 10% of the money on clothes, 20% on games, and the rest on books.

Therefore, The expression that represents the context is,

$(50 - (10/100)×50 - (20/100)×50).

= $(50 - 5 - 10).

= $35.

SO, $35 she spent on books.
