Answer:

7. D) 180

7. C) 24%

7. D) 2 out of 9

7. D

Step-by-step explanation:

36 doesn't go into 5

45 doesn't go into 4

60 doesn't go into 9

180/4 = 45

180/3 = 60

180/5 = 36

180/9 = 20

We can make this problem even easier by converting the denominator from 25 to 100. This can be done with multiplication (x4)

Whatever you do to the denominator, you must also do to the numerator, so if we multiply both sides by 4, we get 24/100, which is equivalent to .24

total: 81 pieces of jewelry

18/81 or 2/9 (divide numerator and denominator both by 9)

.67 = 67/100

.607 = 607/1000 or 60.7/100

.07 = 7% or 7/100

.067 = 6.7% or 6.7/100

Answer: the answer is letter "D" (180)

hope it helped! :)

$12 is 1/4 of how much money (m)?

Answers

Answer:

48

Step-by-step explanation:

If 12 is only 1/4 of the whole (48) you just have to multiply it by 4 to get the remaining 3/4.

Answer:

48

Step-by-step explanation:

If 12 is 1/4 of the total amount, multiply 12 by 4 to get the total amount of money (m).

-----

2/4 would be 24, which is half of the total amount.

3/4 would be 36, which is 3 quarters of the total amount

4/4 (1) would be 48, which is the total amount.

There are 4 green marbles and 7 silver marbles in a bag. You randomly choose one of the marbles. What is the probability of choosing a green marble?

7/11
4/11
4/7
7/4

Answers

Answer:

4/11

Step-by-step explanation:

there are 4 green out of 11 total

Answer:

B.

Step-by-step explanation:

First, you will need to find out how many marbles there are total, which is 11. After doing so, you are able to eliminate two of your answer choices already (C. and D.). Next, identify how many green marbles are in there, which is 4. You are able to identify that A. can be eliminated as well. With you finding probability, the total amount will be on the bottom. So, you can see that there is a 4/11 or about 36% chance that a green marble will be picked.

An angle measures 48.4° less than the measure of its complementary angle. What is the measure of each angle?

Answers

Answer:

The angles are 69.2 degrees and 20.8 degrees

Step-by-step explanation:

Complementary angles, when added together, = 90°

We’ll call the first unknown angle a and the second angle b

b = a - 48.4

a + b = 90

So let’s substitute in for b in the second equation:

a + a - 48.4 = 90

2a - 48.4 = 90

2a = 138.4

a = 69.2

69.2 - 48.4 = 20.8 = b

Now, does a + b = 90?

69.2 + 20.8 = 90

Marty went shopping for school supplies. He bought a package of pens for $2.25, a package of paper for $3.25, a notebook for $5.75, and a package of folders for $3.75. What was the range of prices for the school supplies that Marty bought?

Answers

Answer:

$3.50

Step-by-step explanation:

to find the range you take the highest number and the lowest number and subtract them

so with that, let us do just that-

$5.75, $3.75, $3.25, $2.25

$5.75-$2.25

=$3.5

and since we're dealing with money we must add a '0' to the end of the decimal- $3.50

good luck :)

Answers

Answer:

1,142.5 or 1,143

Step-by-step explanation:

Part A: Start by writing out the equation a2 + b2 = c2. Since both sides a and b are known, fill it in. So, now it is 38 squared + 29 squared = c2. Next, you have to find the square roots for both sides, or legs. For 38 squared, it will be 38 x 38 = 1,444. For 29 squared, it will be 29 x 29 = 841. Now that we both legs, we add that together: 1,444 + 841, which equals 2,285. Then, you need to divide 2,285 by 2, which is 1,142.5

Since you need to round, it would be 1,143.

Part B: 1,143

The answer is 1,143.
