You earn $5.25 per hour. How much will you earn in 25 hours? (multiple choice)
(A) $207.20 (B) $129.50 (C) $131.25 (D) none of these

Answers

Answer 1

Step-by-step explanation:

Look for keywords

when you see "per" that means theres a rate (something happens every unit of time)

To write a rate you divide whatever happens by whatever unit of time youre useing

In this example our rate is 15$ per hour which can be written as:

15$/1 hour (but we usually dont write it if theres a 1)

You can think of this as a regular fraction

[tex] \frac{15}{1 \: hour} \times 25 \: hour[/tex]

Here the hour will cancel and youre left with $

A summer camp tournament starts with 1024 players. After each round, half the players are eliminated. How many players remain after 7 rounds?

I know the answer is 8, but I want to know how to solve it.

Answers

Divide 1024 by its half and keep dividing every number by its half and that is how you solve it
A formula we could use for this... 1024(1/2)^x

That is because this would be equal to 1024 times 1/2, x number of times.

A group of students were surveyed about which type of party they would most want to attend.

boy | girl | total
bowling: 9 6 15
painting: 15 10 25
skating: 6 14 20
total: 30 30 60

What is the experimental probability that the next student randomly selected will be a boy who would most want to attend a skating party?

Answers

Answer:

10%

Step-by-step explanation:

first, we need to know how many boy would attend the skating party. the number is 6. Now, to find the probability, we need to use the percent that 6 is of the total. if we look at the bottom of this table, we see the total people surveyed is 60 people. now, since 60/6=10, 6 is 10 percent of 60. the probability is therefore 10%

A man is trying to zombie-proof his house. He wants to cut a length of wood that will brace a door against a wall. The wall is 4 feet away from the door, and he wants the brace to rest 2 feet up the door. About how long should he cut the brace?

Answers

Answer:

Assuming you're rounding to the nearest tenth, he should cut the brace 4.5 feet long.

Step-by-step explanation:

Since this is a right triangle, you can use the a^2 + b^2 = c^2 easily.

You can use either 2 or 4 as the a or the b.

After filling in the equation, 2^2 + 4^2 = c^2, you can calculate it to find it is 4 + 16 = c^2.

If you add 16 + 4, you get 20. So now, you need to find the square root of 20 which is 4.4721 but if you round to the nearest tenth, you get 4.5^2.

He should cut the brace to 4.5 square feet.

I hope this helps :))
