The area of a rectangle is 47.5 square centimeters. The
base of the rectangle is 5 centimeters. What is the height of
the rectangle in centimeter?

Answers

SHORT ANSWER: 84cm

Let width = w

Let length = w + 5

The area of a rectangle is found by multiplying its width by length and the problem states that the area is 84 cm2.

(Width)(Length) = 84

(w)(w + 5) = 84

w2 + 5w = 84

w2 + 5w - 84 = 0

(w + 12)(w -7) = 0

w + 12 = 0

w = -12

The width of a rectangle can't be NEGATIVE!!! Forget about that!

w - 7 = 0

w = 7

Now go back to naming the variables and replace the w with 7.

Length = w + 5 = 7 + 5 = 12

Width is 7 cm. Length is 12 cm.

Check it. Is 7 x 12 = 84? Yes.

Answer:

9.5

skateboarding ramp is 12in. high and rises at an angle of 23 degrees. How long is the base of the ramp? Round to the nearest inch.

Answers

Answer:

the length of the base of the ramp is 28.27 inches

Step-by-step explanation:

The computation of the length of the base of the ramp is shown below:

Let us assume x be the length of the base of the ramp

Now the following formula should be used

tan = opposite ÷ adjacent

tan 23 degrees = 12 ÷ x

x = 12 ÷ tan 23 degrees

= 12 ÷ 0.42447482

=28.27 inches long

Hence, the length of the base of the ramp is 28.27 inches

Experimental probability of rolling a 3 is:

P(E) = number of times event occurred/ number of experiments P(E) = 44/270 = 22/135

Theoretical probability of rolling a 3 is:

P(T) = number of favorable outcomes/number of total outcomesP(T) = 1/6
