You scored 7 out of 8 on a test. What percent did you get on the test? Remember the % sign on your answer.

Answers

Answer 1

Answer:

7/8=0.875

0.875 x 100= 87.5

so you would score 87.5%, but since test scores usually dont give decimals as a score, i would say to round it to an 88%, pretty good score

Step-by-step explanation:

Answer 2

Answer:

87.5%

Step-by-step explanation:

100/8 is 12.5. that means for each question you get correctly, you add another 12.5 percent to your final score. Got 7 problems? then 7 times 12.5 which is 87.5 so there's your answer is 87.5%.

A baseball coach order hats for his team. Each hat cost $10. The shipping charger is $6. The total cost of the order must be less than $125. Which inequality can be used to solve?

Answers

The answer should be:

10h + 6 < 125

Answer:

10x + 6 < 125

Step-by-step explanation:

Hi,

10x is the cost per hat. 6 is the charging fee. 125 is the total cost of the order. We put x because we don't know how many hats they're going to buy. 6 is the amount they pay no matter what. And < is used because the total cost has to be less than 125, not less than or equal to, but LESS than.

$7.25 for 5 liters

Step-by-step explanation:

If you get the unit rate of $4.47 for 3 liters it is 1.49 per liter.

1.49 x 5 = 7.45

Therefore, $7.25 for 5 liters is a better deal than $7.45 for 5 liters.

Triangle PQR is transformed to triangle P′Q′R′. Triangle PQR has vertices P(8, 0), Q(6, 2), and R(−2, −4). Triangle P′Q′R′ has vertices P′(4, 0), Q′(3, 1), and R′(−1, −2).

Plot triangles PQR and P′Q′R′ on your own coordinate grid.

Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P′Q′R′? Explain your answer. (4 points)

Part B: Write the coordinates of triangle P′′Q′′R′′ obtained after P′Q′R′ is reflected about the y-axis. (4 points)

Part C: Are the two triangles PQR and P′'Q′'R′' congruent? Explain your answer. (2 points)

Answers

Answer:

The scale factor from triangle PQR to P'Q'R' is 1/4.

The length of each side of the triangle is divided by 4, in other words it is multiplied by the scale factor of 4.

If P'Q'R" is reflected over the y-axis the new points would be: (1, 0) (0, 1) and (-2, 1).

No, the triangles are not congruent. There was a dilation of 1/4 in the triangles.

A fair coin is flipped 20 times. If the coin lands on
heads 13 times, which statement is true?
A. The coin lands on heads 3 less times than
expected.
B. The coin lands on heads 3 more times than
expected.
C. The coin lands on heads 5 less times than
expected.
D. The coin lands on heads 5 more times than
expected.

Answers

B because it’s a 50% chance of getting heads/tails and it landed 13 times out of 20 on heads so 3 more then 50% of 20
b because the coin has a 50% chance to land on heads or tails. Which means if its flipped 20 times it has a 50% chance to land on heads which is 10 times. The coin landed on heads 13 tikes which is 3 more than 10

The product of 45 and the counting number n is a perfect cube. find the least possible value for n.
PLS HELP.

Answers

I agree that the answe is 45

The counting number n is 75 which when multiplied with 45 gives perfect cube.

What is a perfect cube?

Numbers which are the triple product of the exact number are known as perfect cubes.

In other words, we can say the value produced by multiplying a whole number by three times itself is a perfect cube.

A number that may be expressed as three times the product of another integer is also termed as a perfect cube.

It is given in the question that the product of 45 and the counting number n is a perfect cube
So, we have to find the counting number n

First of all we will factorise 45

45 = 5 × 9

After factorising we get,

45 = 3×3×5

For 45 to become perfect cube we have to multiply the factors with 3×5²

45 = 3×3×3×5×5×5

∴ 3×5² = 75

Hence , the counting number n is 75 which when multiplied with 45 gives perfect cube.
