Ms. Aniston asked seven students in her class to collect pet food cans for a local animal shelter. The dot plot shows the number of food cans collected by each student. Each dot represents one student. What is the median of the data set? A. 9 B. 7 C. 6 D. 8

Answers

Answer: The answer is going to be 7

Step-by-step explanation: So for this problem it is important to know what a median is. The median is essentially the center number when everything is written out. So you want to take your line plot and write out each number on the bottom as many times as a dot appears above it. For this problem that would look like 6, 6, 7, 7, 8, 9, 9. Since you have seven numbers the center would be the 4th one. In ascending order out of these numbers the 7 occurs fourth thus giving you your answer.

What is the slope of the line that passes through the points (9,4) and (9, -5)? Write your answer in simplest form.

Answers

Answer:

The slope of the line is undefined, and the equation of the line is x = 9.

Step-by-step explanation:

Given the points

(9, 4)(9, -5)

Finding the slope between (9, 4) and (9, -5)

It is clear that the value of x = 9 is the same in both points.

It means no matter what the value of y is, the value of x remains the same.

It means the line is vertical.

Therefore, the slope of the vertical line is undefined, because the value of x is not changing.

Thus, the slope of the line is undefined, and the equation of the line is x = 9.

Step-by-step explanation:

The cube containing 125 = 5³ blocks will have a edge dimension of 5 blocks. The perimeter of one square face will be 4 times the edge dimension of the face, so will be 4×5 blocks = 20 blocks.

If 20 blocks = 20 units, then the edge of one block is 1 unit. Its volume is 1 unit³, or 1.

The appropriate choice is (A) 1 unit³ for the block volume.

how many times does 8 go into 70

Answers

8.75 times
Hope this helps
Ty

8 goes into 70 exactly 8 times, with a remainder of 6.

When dividing 70 by 8, we follow these steps:

Divide the first digit of the dividend (7) by the divisor (8). In this case, 7 divided by 8 is 0 with a remainder of 7.

Bring down the next digit of the dividend (0) and divide it by the divisor (8). 0 divided by 8 is 0.

Since there are no more digits in the dividend, the division process is complete.

The quotient is the result of the division, which is 8. The remainder is the value left over after division, which is 6 in this case.

Therefore, 8 goes into 70 exactly 8 times, with a remainder of 6.

Oscar and Carla deposit $1,000.00 into a savings account which earns 10% interest compounded annually. They want to use the money in the account to go on a trip in 2 years. How much will they be able to spend?

Answers

Answer:

They will be able to spend $1210

Step-by-step explanation:

At the start, there will be $1000 in the savings account that will earn 10% of the current savings(1000) so 1000*(10/100)=$100 so after 1 year in the savings account there will be $1100 the same procces will happen for the next year

2nd year:1100*(10/100)=$110

total=$1100 + $110=$1210

A box of cereal states that there are 75 calories in a three fourths 3/4​-cup serving. What is the unit rate for calories per​ cup? How many calories are there in 2 cups of the​ cereal?

Answers

Answer:

a) The unit rate for calories per​ cup is 100 calories per cup

b) 200 calories in 2 cups of cereal.

Step-by-step explanation:

A box of cereal states that there are 75 calories in a three fourths 3/4​-cup serving.

a) What is the unit rate for calories per​ cup?

This is calculated as:

3/4 cup = 75 calories

1 cup = x

Cross Multiply

3/4x = 75 calories × 1

x = 75 calories /3/4 cup

x = 75 ÷ 3/4

x = 75 × 4/3

x = 100 calories per cup

The unit rate for calories per​ cup is 100 calories per cup

b) How many calories are there in 2 cups of the​ cereal?

From the above question

3/4 cup = 75 calories

2 cups = x

Cross Multiply

3/4x = 75× 2

x = 150 ÷ 3/4

x = 150 × 4/3

x = 200 calories

There are 200 calories in 2 cups of cereal.

8x+5=133

8x=128

x=16

Step-by-step explanation:

16 books

Answer:

He bought 16 books

Step-by-step explanation:

cost = flat fee + books * cost per book

133 = 5 +b*8 where b is the number of books

133 = 5+8b

Subtract 5 from each side

128 = 8b

Divide each side by 8

128/8 = 8b/8

Jack usually mows his lawn in 3 hours. Marilyn can mow the same yard in 6 hours. How much time would it take for them to mow the lawn together?​

Answers

Step-by-step explanation:

Jack mows 1 lawn in 3 hours

= 1/3 lawn in 1 hour

Marilyn mows 1 lawn in 6 hours

= 1/6 lawn in 1 hour

Together, they can mow 1/3 + 1/6

= 1/2 lawn in 1 hour.

Hence they will need 2 hours to mow the lawn.

The sum of three numbers is 4. The second number is 1 more than twice the first. The sum of the first and third is –1. Find the numbers.

Answers

1st condition: x + y + z = 4
2nd condition: y = 2x + 1
3rd condition: x + z = - 1 <=> z = - x - 1

Based on the 2nd and 3rd, we replace the 1st as following:

x + 2x + 1 - x - 1 = 4 <=>

2x = 4 <=>

x = 2

Since x = 2, we solve the 2nd as following:

y = 2x + 1 <=>

y = 2*2 + 1 <=>

y = 4 + 1 <=>

y = 5


Same thing for the 3rd:

z = - x - 1 <=>

z = - 2 - 1 <=>

z = - 3

1. The first number is equal to 2.

2. The second number is equal to 5.

3. The third number is equal to -3.

Let the first number be a.Let the second number be b.Let the third number be c.

Translating the word sentence into an algebraic expression, we have;

The sum of three numbers is 4:

[tex]a+b+c=4[/tex]   ....equation 1.

The second number is 1 more than twice the first:

[tex]b=2a+1[/tex]    ....equation 2.

The sum of the first and third is –1:

[tex]a+c=-1[/tex]    ....equation 3.

From eqn. 3, we have:

[tex]c=-1-a[/tex]   ....equation 4.

Substituting into eqn. 1, we have:

[tex]a+2a+1+(-1-a)=4\\\\3a+ 1-1-a=4\\\\2a=4\\\\a=\frac{4}{2}[/tex]

a = 2

To find the value of b:

Step-by-step explanation:

using eq from problem 4)   y = -45x + 1080

then use the point slope formula with the slope of the above line at -45 and plug in your given point of (8, 240)

y-y1 = m(x-x1)   where m is the slope above

y-240 = -45 (x - 8 )  this is an equation for the line but the teacher probably wants the slope intercept form... the formula is y = mx + b

soooo...

y-240 = -45x + 360

y = -45x +360 + 280

y =  -45x + 640

A man has a garden measuring 40m by 24m. He wants to divide it equally into the minimum number of square plots

Answers

Complete question :

A man has a garden measuring 40m by 24m. He wants to divide it equally into the minimum number of square plots. what is the length of each square plot?

Answer:

8 m

Step-by-step explanation:

Given that :

Dimension of garden = 40m by 24m

Length of garden = 40m

Width of garden = 24m

To Obtain the length of each square plot if the garden is divided into minimum number of square plots ; we take the highest common factor of the dimension:

Length (40) = 1, 2, 4, 5, 8, 10, 20, 40

Width (24) = 1, 2, 3, 4, 6, 8, 12, 24

The highest common factor here is 8 ;

Thus, the length of each square plot is 8m
