Answer:

h = 4.5 inches

Step-by-step explanation:

The area of a trapezoid is given by

A = 1/2 (b1+b2) h

We know A b1 and b2

20.25 = 1/2 (5+4)*h

20.25 = 9/2 h

Multiply each side by 2/9 to isolate h

2/9 * 20.25 = 2/9 *9/2 h

4.5 =h

Solve the system of equations by substitution
scoundrel [369]

Answer:

(x, y) = (1, 3)

Step-by-step explanation:

given the 2 equations

x + y = 4 → (1)

y = 3x → (2)

Substitute y = 3x into (1)

x + 3x = 4

4x = 4 ( divide both sides by 4 )

x = 1

Substitute x = 1 into (2) for corresponding value of y

y = 3 × 1 = 3

solution is (1, 3 )

A submarine was diving at 77.1 feet per minute. Which number represents the position of the submarine in relation to the surface
klasskru [66]

First, Multiply 77.1 by 8 to find how many feet the submarine has dived.

77.1 × 8 = 616.8

Since the question is asking the submarines position "in relation to the surface," this number needs to be negated.

616.8 ⇒ -616.8

<h2>Answer:</h2>

<u>The submarine is at </u><u>-616.80 ft</u><u> in relation to the surface, so </u><u>option B</u><u> is correct.</u>

9 out of 45 apples are red.the situation is looking for the (part, whole, percent)
erastovalidia [21]
The answer would be 20% divide 9 by 45 and you get the answer of 0.2. When we use percents, we multiply the value by 100 so 0.2 x 100 you move the decimal over 2 places to the right. This means it would be 20% of the whole.
