Miss boone has 3 bowls of fruit 1st bowl has 75 apples 2nd has 75 more than 1st 3rd has 36 less than 2nd how much fruit in all
nekit [7.7K]

Answer:

So she will have a total of 339 apples

Step-by-step explanation:

Given:

Total bowls = 3

First bowl have = 75 apples

Second has 75 more then that

Third 36 less then second

To Find:

Total fruits = ?

Solution:

AS given First bowl have = 75 apples

Now according to conditions

Second bowl have = 75 + First bowl have

                                = 75 + 75

                                 = 150 apples

Now

Third bowl have = Second bowl - 36

                            = 150 -36

                            = 114

Total Apples = First bowl apples + second bowl apple + third bowl apples

Putting in the values

Total apples = 150 + 75 + 114

                      = 339

So she will have a total of 339 apples

What is the length of BC on in the right triangle below? Non
skad [1K]

Answer:

C. 20

Step-by-step explanation:

You need you use the Pythagorean Theorem to answer this. We are given the lengths of both legs of the right triangle.

a^2 +b^2 = c^2

If we plug the number given to us into the formula, we get

(12)^2 + (16)^2 = c^2

144 + 256 = c^2

400 = c^2

\sqrt{400} = C

20 = C

2x = 4y + 8, x - 2y = 4
Evgen [1.6K]

Answer: x = 8, y = 2, coordinates (8,2)

Step-by-step explanation:

2x = 4y + 8 (divide by 2 to get value of x)

x = 2y + 4

(now substitute x into the second equation to find value of y)

2y + 4 - 2y = 4

2y - 2y = 4 - 4 (divide by 2 to get value of y)

y - y = 2 - 2

y = 2

Now plug in value of "y" to get value of "x".

x - 2(2) = 4

x - 4 = 4

x = 8

Coordinates (8,2)
