Answers

Answer 1

Answer:

8/10

Step-by-step explanation:

I think that you are probably looking for 0.8 as a fraction because it is a decimal already.

So, 0.8 means %80 such as 8 points out of 10 points

This can be represented as 8/10

There are also many other ways to write it, but it will always simplify down to 4/5. Example: 8/10, 16/20, 24/30

Leonard took ten 15-point quizzes in his geometry class. His total points on the 10 quizzes is 135. What was his mean score? What information is unnecessary to find out the answer?

Answers

Answer:

The mean score is 13.5 points per question.

Step-by-step explanation:

Leonard took ten 15-point quizzes in his geometry class.

His total points on the 10 quizzes is 135.

We expect him to score 10 × 15 = 150 points , if he got all the questions right.

But now he scores 135 points in the 10 questions.

The mean score = Total points scored ÷ tota number of questions

i.e the mean score = 135 ÷ 10 = 13.5

So Leonard scored 13.5 points per question.

Prove the identity cos(x-y)-cos(x+y)=2sinx siny

Answers

Answer:

see explanation

Step-by-step explanation:

Using the Addition/ Subtraction formulae for cosine

Consider the left side

cos(x - y) - cos(x + y)

= cosxcosy + sinxsiny - (cosxcosy - sinxsiny) ← distribute

= cosxcosy + sinxsiny - cosxcosy + sinxsiny ← collect like terms

= 2sinxsiny = right side ⇒ proven

Susan is saving money to buy a game. The game costs $30 , and so far she has saved two-thirds of this cost. How much money has Susan saved?

Answers

Answer:

Susan has saved 20 Dollars so far

$20 because 2/3 of 30 is 20. You can do this by dividing 30 by 3. That is 10. Therefore 10 is 1/3. But since you need 2/3 you must times that by 2, which is 20.

The 1984 movie footloose made $8,556,965 in its opening weekend. The 2011 remake of footloose made $15,556,113 in its opening weekend. What is the absolute and relative change in opening weekend earnings from the original footloose to its remake? Round your answer for relative change to the nearest hundreth of a percent. Do not round until your final answer.

Answers

Answer:

absolute change: $6,999,148
relative change: 81.79%

Step-by-step explanation:

The absolute change is the difference between the earnings numbers:

$15,556,113 -8,556,965 = $6,999,148

The relative change is the ratio of this difference to the original amount:

$6,999,148/$8,556,965 × 100% ≈ 81.794748% ≈ 81.79%
