You would multiply one side by the other side (doesnt matter what sides) and once you have that answer you multipy that answer by the remaining side

Question

Each question mark represents a missing exponent. Find the missing value of the exponent needed to make the equations true. (6^3)^?=1
Please explain how you got your answer. Thanks!

Solution 1

The exponent is 0 because anything with the exponent 0 equals 1.

(6^3)^0=1

(216)^0=1

1=1

(6^3)^0=1

(216)^0=1

1=1

Question

Which statements about prisms are always true if the top base is directly above the bottom base? -The bases are congruent
-The bases can be any shape
-The lateral faces are congruent
-The lateral faces are rectangles

Solution 1

I believe it is the bases are congruent because that means they are similar in shape but can be varying in size.

Solution 2

The bases are congruent and equalÂ

Question

Sara got 98, 100, 65, 78, 98, 46, 100, 100, 45, and 50 on her reading test. Lee got 97, 67, 89, 99, 100, 45, 79, 89, 58, and 67 on his reading test. What is the mean of Sara's reading test? What is the mean of Lee's reading test? please help with both questions.

Solution 1

A **mean **is an **arithmetic **average of a set of **observations. Sara's mean** score is 78, while **Lee's mean** score is 79.

A **mean **is an **arithmetic **average of a set of **observations.** it is given by the formula,

**Mean **= (Sum of observations)/Number of observations

Given the **reading **score of **Sara **are 98, 100, 65, 78, 98, 46, 100, 100, 45, and 50. Therefore, the **mean **will be,

Mean= (Sum of **observations**)/**Number **of observations

Mean = (98+100+65+78+98+46+100+100+45+50)/10

Mean = 780/10

Mean = 78

Given the **reading score **of Lee are 97, 67, 89, 99, 100, 45, 79, 89, 58, and 67. Therefore, the **mean **will be,

Mean= (**Sum **of observations)/Number of **observations**

Mean = (97+67+89+99+100+45+79+89+58+67)/10

Mean = 790/10

Mean = 79

Hence, **Sara's mean** score is 78, while **Lee's mean** score is 79.

Solution 2

**Answer:**

Saras Mean on her reading test is 78

Lee's Mean on his reading test is 79

**Step-by-step explanation:**

You add grades for Sara's test together and then you will divide by the= number of graded test there were and you will get 78.

You add Lee's Grades for the test together and divide by the number of graded test there were and you will get 79.

Question

A decorative fish tank is in the shape of a right rectangular prism is shown in the diagram. What is the volume of the fish tank? A) 18 mÂ³ B) 2212 mÂ³ C)2614 mÂ³ D)105 mÂ³

Solution 1

To solve for the volume of a prism, you have to do B*h/3. So whatever your height is, multiply by the area of the base to get the volume.Â

Question

The table shows the weekly change in the water level in a swimming pool. After 4 weeks, the pool owner adds water to return the water level back to the original level. Raising the water level by 1 inch requires 320 gallons. The water hose has a flow rate of 5.75 gallons of water per minute. Will it take less than an hour to fill the pool back to return the water level to the original level? Explain your reasoning. Week: Â Â Â Â Â Â Â Â Â Â Â Â Â 1 Â Â Â Â Â Â Â 2 Â Â Â Â Â Â 3 Â Â Â Â Â Â Â 4
Change (in.): Â Â Â Â Â Â - 1/2 Â Â Â Â Â 3/4 Â Â Â Â -1 1/8 Â Â Â -1 3/8
The original question does not mention anything about the water levels.

Solution 1

So we just need to raise the pool back to original level

in total, the pool drained a total of 1 and 3/8 inches

so we need to find out how long it would take to raise the pool by 1 and 3/8 inches

1 inch=320 gallons

1 and 3/8=320 times 1 and 3/8=320 and 960/8=440

he needs to put in 440 gallons

it is 5.75 gallons per minute

find out how many minutes it will take

440=5.75 times x minutes

divide both sides by 5.75

76.521=xminutes

round

77 minutes

1 hour=60 minutes

77>60

it will take more than 1 hour to make the pool back to original level

Question

The probability of winning a game is 25% . How many times should you expect to win if you play 36 times ? 1. 3 times
2. 7 times
3. 9 times
4. 11 times

Solution 1

25% of 36 = 0.25 x 36 = 9

**Answer: 9 times**

Solution 2

The answer is 9 times. If u struggle w probability like I do u can do it a different way w/our decimals. (Only works for 25,50 and 75%). U can take 25 and know itâ€™s 1/4 of one hundred. U take the 4 and divide. 36/4 = 9. This way is easier for me but if I like the decimal way the. Go for it. My mind works in mysterious ways. ;)

Question

Raul walks 3/8 of a mile to school Laurie walks two thirds of a mile to school how much longer is Lori's walk then Raul's walk

Solution 1

Hello!

First you have to make the denominators the same

2/3 = 16/24

3/8 = 9/24

Now you subtract them

16/24 - 9/24 = 7/24

The answer is 7/24

Hope this helps!

Question

A miner descended 1200 feet into a mine. While in the mine, he then rose 450 feet and then descended 150 feet. What was the miner's net gain or loss in altitude? 1500 ft 600 ft â€“1500 ft â€“900 ft

Solution 1

The net loss is 1150

Solution 2

So, let's solve it!

If he rose 450:

1200 + 450 = 1650

If he descended 150:

1650-150 = 1500

**1500 feet, his net gain is -300 feet, his loss is 300 feet**

If he rose 450:

1200 + 450 = 1650

If he descended 150:

1650-150 = 1500
