Answer:

x = 9.5

Step-by-step explanation:

We see that the entire length of DF is equal to 34. That means segment DE and segment EF must combine to equal 34:

3x - 6 + x + 2 = 34

4x - 6 + 2 = 34

4x - 4 = 34

4x = 38

x = 9.5

The length of a rectangle is 9 inches more than half the width. Find the length if the perimeter is 60 inches.

valentina_108 [34]

Answer:

Length = 10.435 inches

Step-by-step explanation:

Let the length be l

Let the width be w

Since the length is 9 inches more than half the width.

Then;

L = 0.5w + 9

Perimeter of a rectangle is;

P = 2Lw

Thus;

P = 2w(0.5w + 9)

Since perimeter = 60

Then;

2w(0.5w + 9) = 60

w² + 18w = 60

w² + 18w - 60 = 0

From quadratic formula;

w ≈ 2.87 in

L = 0.5(2.87) + 9

L = 10.435 in

Help! I don’t understand this

Papessa [141]

Answer:

1/2

Step-by-step explanation:

A sample space is a collection or a set of possible outcomes of a random experiment.

I have created the sample space for these data and attached it. As you can see there are 16 possible outcomes.

To find the probability that the total showing is greater than 9, simply identify the number of values in the sample space that are greater than 9.

(I have highlighted these in yellow).

Therefore, P(X>9) = 8/16 = 1/2
