The area for a trapezoid is given by the formula below, where a and b are the lengths of the two bases and h is the height of th
aivan3 [116]

Answer:

C

Step-by-step explanation:

Given

A = \frac{h(a + b)}{2}

Substitute the given values with h = a, then

16.5 = \frac{a(a+8)}{2} ( multiply both sides by 2 )

33 = a(a + 8) ← distribute

33 = a² + 8a ( subtract 33 from both sides )

0 = a² + 8a - 33 ← in standard form

0 = (a + 11)(a - 3) ← in factored form

Equate each factor to zero and solve for a

a + 11 = 0 ⇒ a = - 11

a - 3 = 0 ⇒ a = 3

However, a > 0 thus a = 3

Hence the height is 3 feet

Please help!!! ABCD is a square with diagonals intersecting at E. What is the length of BE
Snezhnost [94]

Answer:

BE = 4\sqrt2

Step-by-step explanation:

Given

The attached square

Required

Find BE

First, we calculate BD (the diagonal) using Pythagoras theorem.

BD^2 = BA^2 + AD^2

Since the shape is a square, then

BA = AD = 8

So:

BD^2 = 8^2 + 8^2

BD^2 = 2(8^2)

Take square roots

BD = \sqrt{2(8^2)

BD = \sqrt{2} * 8

BD = 8\sqrt{2}

BE is half BD.

So:

BE = \frac{1}{2} * BD

BE = \frac{1}{2} * 8\sqrt2

BE = 4\sqrt2

The after school craft center has 15 boxes of 64 crayons each. In 12 of the boxes , 28 of the crayons have not been used. All th
Korolek [52]

The <em><u>correct answer</u></em> is:

624 crayons.

Explanation:

In 12 of the boxes, 28 crayons have not been used; this leaves 64-28=36 crayons that have been used. 12(36) = 432 crayons have been used in these boxes.

3 full boxes have been used; this is 3(64) = 192 crayons.

Together this makes 432+192 = 624 crayons that have been used.

Finding the quotient of this answer
Mekhanik [1.2K]
30/36 or 5/6 because to divide by a fraction, you multiply by its reciprocal.To find the reciprocal of a fraction you can simply just flip the fraction so 6 / (5/6) is equal to 6*(5/6).This is equal to (6*5)/(6*6) or 30/36 or 5/6.
