**Answer:**

**D. **

**Step-by-step explanation:**

We have been given a table of values. We are asked to find the equation that shows the relationship between x and y.

x y

0 0

1 5

2 10

3 15

Upon looking at our given table, we can see that with each increase in x value, the value of x increases by 5. This means that slope of our given line is 5.

We can also see that initial value or y-intercept is 0.

Upon substituting our given values in slope intercept form of equation, we will get:

**Therefore, our required equation is and option D is the correct choice.**

X y

0 0

1 5

2 10

3 15

The answer is y = 5x

we can check this by plugging in the numbers from the table:

5 = 1(5)

5 = 5

This makes this answer correct because it makes the equation true.

0 0

1 5

2 10

3 15

The answer is y = 5x

we can check this by plugging in the numbers from the table:

5 = 1(5)

5 = 5

This makes this answer correct because it makes the equation true.

Question

A bag holds 500 grams of sand. About how many grains of sand are in the bag? There are about 1,000 grains of sand in 1 gram.

Solution 1

500000 is the answer you are looking for my friend :D

Solution 2

1,000=1 gram so you would multiply 1,000 by 500 which is 500,000. So 500,000 grains of sand. Hope this helps!

Question

Sara got 88, 90, 75, 78, 100, 54, 90, 100, 45, and 60 on her English tests. Lee got 77, 67, 99, 79, 100, 65, 79, 89, 58, and 67 on his English tests. What is the mean of Sara's English tests? What is the mean of Lee's English tests? please answer both questions

Solution 1

The mean is the average, so I added up all the numbers and divided that by the number of tests:

**Sara's mean: 78**

**Lee's mean: 78**

Solution 2

Sara:

88, 90, 75, 78, 100, 54, 90, 100, 45 and 60

add them all up which is 780

then divide by the number of test results you have which is 10

780/10

Sara's mean is 78 on her test scores.

Lee:

77, 67, 99, 79, 100, 65, 79, 89, 58, 67

add them all up which is 780

divide by the number of test results 10

780/10

Lee's mean is 78 on her test scores.

88, 90, 75, 78, 100, 54, 90, 100, 45 and 60

add them all up which is 780

then divide by the number of test results you have which is 10

780/10

Sara's mean is 78 on her test scores.

Lee:

77, 67, 99, 79, 100, 65, 79, 89, 58, 67

add them all up which is 780

divide by the number of test results 10

780/10

Lee's mean is 78 on her test scores.

Question

Translate the sentence into an equation.The difference of a number times 3 and 8 is 2. Use the variable c for the unknown number. How do I figure this out?

Solution 1

I hope that this is what you are looking for....

**C X 3(8) = 2**

The parenthesis means to multiply again.

Hope that this helps... :)

The parenthesis means to multiply again.

Hope that this helps... :)

Solution 2

-3c+8=2 you minus 8 on both sides of the equation then you'll get -6 then divide -3c by -6 so c equals to 2 c=2

Question

How many times can 448 go into 8

Solution 1

It goes in 56 times. 448/8=56

Solution 2

It could go into it 56 times. You could have just divide it but heres the answer

Question

The school's basketball team lost 4 times as many games as they won. They also tied 5 fewer games than they won. If they played 43 games, how many did they lose?

Solution 1

Let w won games, t tied games, s lose games

s=4w

t=w-5

s+t+w=43

4w+(w-5)+w=43

6w=48

w=7

s=4*7=21 games lost

s=4w

t=w-5

s+t+w=43

4w+(w-5)+w=43

6w=48

w=7

s=4*7=21 games lost

Question

How do you find the area of a congruent triangle ?

Solution 1

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 equal

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 m³ B) 2212 m³ C)2614 m³ D)105 m³

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.
