Answer:

1/9

Step-by-step explanation:

8/9 ÷ 8/1

8/9 x 1/8 = 8/72

The GCF for 8 and 72 is 8

\frac{8}{72}÷\frac{8}{8}=\frac{1}{9}

Answer:

C. 29.50p + 15 = 133

Step-by-step explanation:

p is the number of people going to concert

so the total cost of tickets: $29.50 times the number of people = 29.50p

and add the parking cost $15

so the total is 133 = 29.50p + 15 or 29.50p + 15 = 133

What is the sum of the lengths, in centimeters, of the two legs of a 30-60-90 right triangle, if the length of the hypotenuse is
Nesterboy [21]

The sum of the lengths of two legs of the 30°-60°-90° right triangle is 6.69 centimeters. Using the ratio of sides for the 30°-60°-90° triangle, the sum is calculated.

<h3>What is the ratio of sides for the 30°-60°-90° triangle?</h3>

The ratio for the 30°-60°-90° triangle is 1:√3:2 or x:x√3:2x

where x corresponds to the length opposite the 30° angle and x√3 is opposite of the 60° angle and 2x is opposite to the 90° angle.

<h3 /><h3>Calculation:</h3>

It is given that the triangle is a right triangle with angles 30°-60°-90°

For such a triangle, the ratio of side lengths is x: x\sqrt{3}:2x

we have the length of the hypotenuse is 2\sqrt{6}

So, 2x = 2\sqrt{6}

⇒ x = \sqrt{6}

So,

the other length of the other leg is x√3 = √6 × √3 = 3 √2

Then, the sum of these two legs = √6 + 3√2 = 6.69 centimeters.

The diameters of Douglas firs grown at a Christmas Tree Farm are normally distributed with a mean of 4 inches and a standard dev
leva [86]

Answer:

The proportion of trees greater than 5 inches is expected to be 0.25 of the total amount of trees.

Step-by-step explanation:

In this problem we have a normal ditribution with mean of 4.0 in and standard deviation of 1.5 in.

The proportion of the trees that are expected to have diameters greater than 5 inches is equal to the probability of having a tree greater than 5 inches.

We can calculate the z value for x=5 in and then look up in a standard normal distribution table the probability of z.

z=\frac{x-\mu}{\sigma}=\frac{5-4}{1.5}=0.67

P(x>5)=P(z>0.67)=0.25  

The proportion of trees greater than 5 inches is expected to be 0.25 of the total amount of trees.
