A tree has a shadow length of approximately 9 feet. The distance from the tip of the tree to the tip of the shadow is bout 15 feet. How tall is the tree?

Please help!!!!!

Answers

Answer 1
this is a right triangle equation
so a^2 + b^2 = c^2
c^2 is the hypotenuse and the 15 feet

a^2 + 9^2 = 15^2
a^2 + 81 = 225
a^2 = 144

the square root of 144 is 12

the tree is 12 feet tall
Answer 2

Answer:

12

Step-by-step explanation:

if you draw the picture in your copybook you will see that there is a right triangle, we have the Pythagorean theorem i.e c=√a²+b²

15=√9²+x². the trees tall=X

15²=9²+x²

x²= 144

X= 12

The sum of the perimeters of 2 different squares is 68 feet, and the difference between their perimeters is 12 feet. What is the side length of

each square?

Answers

9514 1404 393

Answer:

10 ft7 ft

Step-by-step explanation:

The side lengths are 1/4 of the perimeter, so we can say ...

  the sum of side lengths is 68 ft/4 = 17 ft

  the difference of side lengths is 12 ft/4 = 3 ft

Using x to represent the side length of the smaller square, we have ...

  x + (x +3) = 17 . . . . . . the larger square has side length x+3

  2x = 14 . . . . . . . . . subtract 3

  x = 7 . . . . . . . . divide by 2

The side lengths of the squares are 7 feet and 10 feet.

A factory uses 3/4 of a barrel of raisins in each batch of granola bars. Yesterday, the factory

Write your answer as a fraction or as a whole or mixed number.

Answers

By solving a simple quotient with the mixed numbers/fractions, we will see that they made 2 batches.

How many batches of granola bars did the factory make yesterday?

We know that the factory uses 3/4 of a barrel for a batch of granola bars.

In this case, we know that yesterday they used (1 + 1/2) barrels of raisins, to see how many batches of granola bars they made, we need to take the quotient between the total amount used and the amount needed for a single batch.

N = (1 + 1/2)/(3/4)

The quotient can be written as:

N = (1 + 1/2)*(4/3) = 4/3 + 4/6 = 4/3 + 2/3 = 6/3 = 2

They made 2 batches.

Mile is obsessed with her new book she started. She read 185 pages in 2 days. If she keeps up this pace about how many pages will she have read after 5 days

Answers

Answer:

462.5 pages

Step-by-step explanation:

You find out how many books she reads in 1 day then you can multiply it by 5 to get 5 days.

If she reads 185 in 2 days. Divide 185 by 2 to get 1 day.

185/2 = 92.5 pages

Now multiply 92.5 by 5 to get how many pages she read after 5 days.

92.5 x 5 =    462.5 pages

18 bottles of water cost $9. How much does it cost for one bottle of water? How much bottles can you buy with $6?​

Answers

Answer:

Water cost 2$ you can buy 3 water bottles with 6$

Step-by-step

I did myself

Answer:

one bottle of water is 0.5 dollars. You can buy three bottles of water for $6

Step-by-step explanation:

since 9 divided by 18= 0.5, this is how it goes

18 bottles broken up into sections of one (one bottle in each section)

so you have to break up the dollars into cents to put an equal amount with each bottle. So you get 100 pennies for each dollar. There's only 9 dollars, so you split the pennies (that you broke from the 9 dollars) and put one in each section (each section still has one bottle) so each bottle with get one more penny with every round. The bottles take turns getting pennies. After you do all of them you will get 0.5 dollars for each bottle so that's how much the bottles cost.

The bottles cost 0.5 dollars.

Now we do this with 6 dollars instead of 9. You now know that each bottle cost 0.5 dollars so you have to do this

0.5 x 6 which = 3.

You can buy 3 bottles with $6.

I hope this helps!
