Answers

first find common denominator, i went with 30. multiply the numerators, they should be 12/30 and 25/30. now just subtract 25/30-12/30 which gives us 13/30.
ANSWER: 13/30 or 26 minute difference

The number of hours Kelly drove longer than Joshua is 13/30 hours.

What is a fraction?

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

The number of hours driven by Kelly.

= 5/6 hours

The number of hours driven by Joshua.

= 2/5 hours

Now,

The difference between the number of hours driven by Kelly and Joshua.

= 5/6 - 2/5

= (25 - 12)/30

= 13/30

Thus,

Kelly drove 13/30 hours longer.

Step-by-step explanation: since all the angles in the triangle equal 180, you take the angle you already have, 76, But because the sides are equal, the angle adjacent to the 76 is also 76. Now you add 76 and 76, 152, then you subtract that from 180, which is 28. You now take the 28 and put it equal to the 3x-5 and solve for x.

A store called Surfmania sells a $170 surfboard for 30% off. Another store, Coolwaves, advertises the same $170 surfboard for 10% off, but then offers to reduce that sale price by 20%. Which store has the better deal, and what is the savings compared to the other store? Surfmania, $3.40 in savings Surfmania, $3.40 in savings Surfmania, $5.60 in savings Surfmania, $5.60 in savings Coolwaves, $3.40 in savings Coolwaves, $3.40 in savings Final prices are the same. Final prices are the same.

Answers

Answer:

Surfmania, $3.40 in savings

Step-by-step explanation:

First, find the price with Surfmania:

170(0.7)

= 119

Find the price with Coolwaves now:

170(0.9)

= 153

153(0.8)

= 122.4

Now, find the amount in savings:

122.4 - 119

= 3.4

So, Surfmania has the better deal with $3.40 in savings.
