This morning, Megan and her dad had smoothies for breakfast. Megan made her smoothie with 1 cup of mango and 3 cups of strawberries. Her dad made a giant smoothie with 2 cups of mango and 6 cups of strawberries. Did the smoothies have the same ratio of mango to strawberries?

If correct I will give brainliest

Answers

Megan’s and her dad’s smoothies have the same ratio mango to strawberry

The smoothies have the ratio of mango to strawberries will be the same.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

This morning, Megan and her dad had smoothies for breakfast. Megan made her smoothie with 1 cup of mango and 3 cups of strawberries.

Then the ratio is given as,

⇒ 1 / 3

Her dad made a giant smoothie with 2 cups of mango and 6 cups of strawberries.

Then the ratio is given as,

⇒ 2 / 6

⇒ 1 / 3

The smoothies have the ratio of mango to strawberries will be the same.

A carpenter had a board that was 2 yard long. He used 18 inches on a project. How many feet long was the board when he was done?

2 1/2 feet

4 1/2 feet

3 3/4 feet

1 1/4 feet

Answers

Answer:

4 1/2 ft

Step-by-step explanation:

1 yard = 36 inches

2 yards = 2 × 1 yard = 2 × 36 inches = 72 inches

The board started with a length of 72 inches.

He used 18 inches.

72 in. - 18 in. = 54 in.

He has 54 in. left.

Now we convert 54 in. to ft.

1 ft = 12 in.

54 in. × (1 ft)/(12 in.) = 4.5 ft = 4 1/2 ft

This is the graph of f(x) = x+A/x+B. The grid lines in the graph are one unit apart. What is the value of A/B

Answers

The value of A/B is given as follows:

A/B = -2.

What are the asymptotes of a function f(x)?

The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.

From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:

B = -1 -> as x + B = 0 -> x = -B = -1.

When x = 0, y = -2, hence the value of A is obtained as follows:

A/-1 = -2

A = 2.

Then the division is given as follows:

A/B = 2/-1 = -2.

Answer:

Q1- total amount of negative balances: -95.75

Q2- Total amount of positive balances: 140.2

Q3- D:129.86

Q4- D: 37.84

Step-by-step explanation:

Q1- Add up all the negative numbers: (-19.00)+(-30.25)+(-46.50). this turns into: -19.00-30.25-46.50= -95.75

Q2- Add up all the positive numbers: 56.84+83.36= 140.20

Q3- use one of the numbers that were given to you and subtract account E from it and you should get the amount in account C. In this case we use $129.86.

So 129.86-46.50= 83.36

Q4- Add up both accounts. Account B is a negative amount and account A is a positive amount, we do -B+A

-19.00+56.84= 37.84

Answers

answer: 1/7

the formula for slope is rise over run, or y1-y2 divided by x1-x2. we can choose either number as y1 or y2 but it needs to stay consistent with x

so let’s plug in from your table.

0-1 divided by -7 -0
(you could also do 1-0 divided by 0-(-7))

-1/-7 which equals 1/7

so, your slope is 1/7

-3 + 6x. Which expression shows the correct factorization?
Here are the ones to pick from
1. -2 + -2 +6 +x
2. 6(-2 +x)
3. 6(-2 +x)
4. -3 (1 - 2x)

Answers

Answer:

Option #4

Step-by-step explanation:

Expand option #4

=-3(1-2x)

=-3 -2x*-3

=-3+6x which is what your original equation was.

becoz it is a multiple choice, we can go by elimination, hence when we expand #4, we will get -3+6x

Fatimah is driving at 1.5 km in 2 min. What is distance she covered in 2 1/4 h?

Answers

Answer:

101.25 km

Step-by-step explanation:

To solve, we need to first find how much she drives in one minute and then multiply that by the number of minutes she drives.

1.5 km = 2 minutes

divide both sides by 2.

1 minute = 0.75 km

2.25 hours = 2.25 * 60 = 135 minutes

Multiply the speed by the time to find distance.

135 * 0.75 = 101.25 km

Thus, she covered 101.25 km in 2 1/4 hours.

101.25km

Answers

Answer:

reflected across the y-axis, vertical compression by 1/2, shifted 4 to the left, shifted 1 down

Step-by-step explanation:

the negative sign indicates a reflection across the y-axis

the $\frac{1}{2}$ outside of the parentheses indicates a vertical compression because it is being multiplied and 0 < $\frac{1}{2}$ < 1

the 4 within the parentheses indicates a shift to the left because it is being added

the 1 outside of the parentheses indicates a shift down because it is being subtracted
