Answers

Answer:

A and B

Step-by-step explanation:

QUESTION A:

Find the GCD (or HCF) of numerator and denominator

GCD of 15 and 30 is 15

Divide both the numerator and denominator by the GCD

15 ÷ 15

30 ÷ 15

Reduced fraction:

1/2

Therefore, 15/30 simplified to lowest terms is 1/2.

Thus, option d is your answer

QUESTION B:

Find the GCD (or HCF) of numerator and denominator

GCD of 12 and 3 is 3

Divide both the numerator and denominator by the GCD

12 ÷ 3

3 ÷ 3

Reduced fraction:

4/1

Therefore, 12/3 simplified to lowest terms is 4/1 or 1/4.

Thus option a is your answer

Answers

Answer:

4/13

Step-by-step explanation:

The total number of marbles is 4 + 9 = 13.

The probability of choosing a yellow marble is the number of yellow marbles divided by the total number of marbles. Since there are 4 yellow marbles, the probability of choosing a yellow marble is 4/13.

Kimo paid $24 for the shirt which was 75% of the regular price. What was the regular price?

Answers

18, never never trying to find the percentage you have to move the decimal two places over So instead of 75% it would be .75 then you multiply .75 by the original price
18 because if you search up “what’s 75% of 24?” It will say 18

Jill and Kyle get paid per project. Jill is paid a project fee of $45 plus $10 per hour. Kyle is paid a project fee of $20 plus $14 per hour. Write an expression to represent how much a company will pay to hire both to work the same number of hours on a project.

Answers

The answer is 65+24h. Explanation below.

We will be using (h) to represent the amount of hours. For Jill, the expression will be 45+10h and for Kyle the expression will be 20+14h. Fee+hourly pay x hours.

To get the total amount the company will pay to hire both Jill and Kyle, you must combine both of their expressions. So 45+20= 65, and 10+14=24. So now the expression= 65+24h

So the answer is that the company will be paying 65+24h dollars to hire both Jill and Kyle:)

Answer:

65+24h

Mollie wants to know which type of book is most commonly checked out by visitors of herlocal public library. She surveys people in the children’s reading room between 1:00 and 2:00 on a Saturday afternoon. Is Mollie’s sample ​representative​ of the population? (6.1)

a.) Yes, Mollie’s sample is representative because she went on a Saturday afternoon.
b.) Yes, Mollie’s sample is representative because she only asks people in the children’s section
of the library.
c.) No, Mollie’s sample is not representative because she went on a Saturday afternoon.
d.) No, Mollie’s sample is not representative because she only asks people in the children’s
section of the library.

Answers

It’s d, only going on Saturday afternoon would mean it doesn’t represent the majority of the population, so a is out, as well as b because the children aren’t the only population; there are adults at the library. Lastly, although the c could be an option, Saturday afternoon doesn’t have as much of an impact as only asking children so d is the best option.

(PLSSS HELP)A bag contains 10 marbles: 5 are green, 3 are red, and 2 are blue. Ivanna chooses a marble at random, and without putting it back, chooses another one at random. What is the probability that both marbles she chooses are red?

Answers

Answer:

[tex]\frac{1}{15}[/tex]

Step-by-step explanation:

Let's first find the probability that she chooses a red marble the first time.

There are 10 marbles and 3 red marbles, therefore the probability of choosing a red marble is:

[tex]\frac{3}{10}[/tex]

The second time, there are only 9 marbles remaining as she does not put the marble back. In addition, assuming she drew a red marble, there are only 2 red marbles left. Therefore the probability she chooses a red marble the second time is:

[tex]\frac{2}{9}[/tex]

Now, we multiply the two fractions:

[tex]\frac{3}{10}*\frac{2}{9}=\frac{6}{90}=\frac{1}{15}[/tex]

Therefore the probability that boht marbles she chooses are red is:

[tex]\frac{1}{15}[/tex]

Answer:

1/15

Step-by-step explanation:

There are 10 marbles in total, 3 are red which makes a probability of 3/10.

After Ivanna randomly selects a red marble, there are 9 total marbles left and 2 red remaining. This makes the probabilty of 2/9. And since the equation asks for the probabilty of both events to be true, multiply the equation. below is how I worked out the solutions.

3/10 * 2/9 = 1/15

A car used 1/64 of a gallon of gas to drive 1/4 of a mile how many miles can the car travel using 1 gallon of gas

Answers

Answer:

16 miles

Step-by-step explanation:

I took 1/64 and divided the 64 by 4, since it takes 4/64 of a gallon to drive one mile. I got 16 from that division, making the answer 16 miles.

4/4 = 1 mile

4/64 gal = 1 mile

16 x 4 = 64

You multiply 1/4 by 64 which will give you 16

Which of the following statements is not true about the graph of a system of equations with infinitely many solutions? please answer correctly!

Answers

Answer:

The lines will have one positive y-intercept and one negative y-intercept is not true about the graph of a system of equations with infinitely many solutions.

Step-by-step explanation:

A system of equations with infinitely many solutions suggests on the graph, the equations will appear to be the same (they will look like one graph) because all points on each equation are equal. This suggests that it's impossible for the y-intercepts to be different, which is why the "lines will have one positive y-intercept and one negative y-intercept " is a false statement.
