Tam needs a total of 2 pounds of vegetables for a soup recipe.
He already has 2/3 pound of carrot and 1/4 pound of celery

how many more pounds of vegetables does he need to buy?

Answers

Answer:

1 1/12 pounds

Step-by-step explanation:

2/3+1/4-2=-1 1/12

your answer would be 1 and 1/12. to get how many pounds he has already you need to find a common denominator, that denominator would be 12. so 2/3 turns into 8/12 and 1/4 turns into 3/12. add them together you get 11/12 which isn’t one pound yet. to get 1 pound you add 1/12 of a pound more. to get 2 pounds add 1 pound. since he didn’t have that 1 pound yet or that 1/12 of a pound yet they go together (1 and 1/12)

Answers

Answer: There are between 9 and 10 ounces of fluid in container B.

Step-by-step explanation: There are between 9 and 10 ounces of fluid in container B. To find the number of ounces in container B, divide the number of ounces in container A by 8. This gives 76 / 8 = <<76/8=9.5>>9.5 ounces. Since 9.5 is between 9 and 10, the correct answer is "There are between 9 and 10 ounces of fluid in container B."

9 and 10 fluid ounces in each

Find the percent equivalent 6 over 15.

Answers

Answer:

40%

Step-by-step explanation:

Because 15 is the denominator in 6/15, we might change the fraction to make 100 the denominator. In order to do it, 100 is divided by the numerator:

=40/100

Now that we know our fraction is 40/100, we can see that 40% of 6/15 is represented as a percentage.

therefore youre answer would be 40%

Answer: y= - 1/4x + 1/4

Step-by-step explanation:

Equation for those points

Y=-1/4x+1/9 is the answer

If x and y vary directly and y is 3 when x is 4, find y when x is 12.

Answers

Y is equal to 9 because it is an inverse equation so you would do 3/4 = x/12 then you would cross multiply and divide by 4 giving you 9

Answer: Y is 9 when X is 12.

Step-by-step explanation:

Here is how you do it.

1. Make a table of x and y

x: 4,

y:3,

2. Keep continuing the table with list of numbers until x=12

x:4,8,12

y=3,6,9.

As you can see, when x is 12 y is 9.

Answers

Answer:

There are 16 nickels and 15 dimes.

Step-by-step explanation:

let x = number of dimes

let y = number of nickels

x + y = 31

.1x + .05y = 2.30

Solve x + y = 31 for x

x = 31 - y

multiple the second equation by 100 to eliminate the decimals.

10x + 5y = 230  Substitute 31 - y for x

10(31-y) + 5y = 230  Distribute the 10

310 -10y + 5y = 230  Combine like terms

310 -5y = 230  Subtract 310 from both sides

-5y = -80  Divide both sides by -5

y = 16

There are 16 nickels.

Plug in 16 for y to solve for x

x + y = 31

x + 16 = 31  Subtract 16 from both sides

x = 15

There are 15 times.

Check:

10x + 5y = 230

10(15) + 5(16) = 230

150 + 80 = 230

230 = 230

Mr. Townsend needs to make 13 pairs of butterfly wings for costumes for a play. Each pair of wings is made with yard of fabric. The fabric costs $8 per yard.

You'll apply properties of multiplication in the following steps to find the total cost of the fabric.
1. Use multiplication to write an expression for the amount of fabric needed to make 13 pairs of wings. (2 points)

2. Multiply the amount of fabric by the price per yard to find an expression for the total cost.(2 points)

3. Use the associative and commutative properties to rearrange the terms in the expression to make it easier to calculate. Explain why the rearranged expression is easier to work with. (3 points)

4. Simplify your expression to find the total cost. Show your work. (3 points)

Answers

Answer:

Step-by-step explanation:

1. 13 x 8 - One pair of wings needs one yard of fabric, which is $8. Therefore, one pair of wings cost $8.

2. 104 - The result of multiplying 13 x 8

3. 13 x (4 x 2) - This is easier because smaller numbers are more familiar and understandable to our brains.

4. 13 x (4 x 2)

13 x 4 = 52

52 x 2 = 104

   

A runner completed a 26.2-mile marathon in 210 minutes.
- Estimate the unit rate, in miles per minute. Round your answer to the nearest hundredth.
- Estimate the unit rate, in minutes per mile. Round your answer to the nearest tenth.
- Another runner says, "I averaged 10-minute miles in the marathon." Is this runner talking about the unit rate described in part (a) or in part (b)?
- Explain your reasoning.

Answers

Answer:

0.123 miles per min

8 mins per mile

The runner is talking about part (b)

Part a) is miles per minute and the runner said they did 10 minutes every mile same thing as minutes per mile or part b

Step-by-step explanation:

Since your doing per minute you do you do the amount of miles over the amount of minutes so you can see how many miles the runner went in each minute

And when doing per mile its the same idea you just minutes over miles now so you get for every mile the number of minutes.
