One side of a triangle is one-fourth the longest side. The third side is
8 feet less than the longest side. The perimeter is
118. Find all three sides.

The sides have lengths of______ ,___________ , and________ feet.

Answers

Answer:

Step-by-step explanation:

Let's call A the longest side. The others triangle sides are B and C.

We know that B = (1/4)*A and C = A - 8

The triangle's perimeter is: A + B + C = 118

Substituting the values of sides B and C, we have:

A + (1/4)A + (A-8) = 118

Adding common terms: (2 + 1/4)A = 118 + 8

(9/4)A = 126 then, A = 56 feet

B = (1/4)A = 14 ft

C = A - 8 = 48 feet

Randal's dad is installing a new pool in their backyard. The pool is a square and has an
area of 121ft? Randal's dad will then build a 4 ft wide deck to surround the pool.
What is the outside perimeter of the deck?

Answers

Answer:

76 feet.

Step-by-step explanation:

The side of the pool = square root of 121 = 11 feet.

With the deck the length of 1 side will be 11 + 2 *4 = 19 feet.

There are 4 sides in the outside perimeter so the answer:

= 4 * 19 = 76 feet.

Among the thirty largest U.S. cities, the mean one-way commute time to work is 25.8 minutes. The longest one-way travel time is in New York City, where the mean time is 38.5 minutes. Assume the distribution of travel times in New York City follows the normal probability distribution and the standard deviation is 7.2 minutes. Use Appendix B.3. What percent of the New York City commutes are for less than 26 minutes

Answers

Answer:

4.093%

Step-by-step explanation:

Here, we want to calculate the proportion of Newyork commutes that are less than 26 minutes

We start by calculating the z-score

z = (x - mean)/SD

here;

x = 26

mean = 38.5 minutes

SD = 7.2 minutes

Thus, we have;

z = (26-38.5)/7.2

z = -1.74

We proceed to use the standard normal distribution table to get the probability of P(x < -1.74)

That will be 0.04093

So the proportion will be this in %

That will be 4.093%
