the directions for lemonade say to put 2 cups of liquid concentrate into 1 gallon of water. if you only want to make 1 pint of lemonade, how many fluid ounces of concentrate should you use

Answers

Answer:

We need 2 fluid ounces of the liquid.

Step-by-step explanation:

We have that,

Ratio for the cups and the water = 2 cups : 1 gallon.

It is required to find the number of cups to be added in 1 pint of lemonade.

Since, we know,

1 cup = 8 ounces i.e. 2 cups = 16 ounces

1 pint = 16 ounces

1 gallon = 128 ounces

Thus, we have the relation between ratio of the cups and the liquid as,

(16)/(128)=(x)/(16)

i.e. x=(16* 16)/(128)

i.e. x=(256)/(128)

i.e. x = 2

Thus, we need 2 fluid ounces of the liquid.

Which Of These Equations Is Equivalent To 6 3/3 x 3 1/4 = 19? A. 3 1/4 ÷ 19 = 6 3/4 B. 19 ÷ 3 1/4 = 6 3/4 C. 3 1/4 ÷ 6 3/4 = 19 D. 6 3/4 ÷ 3 1/4 = 19

Answers

Final answer:

The equation that is equivalent to 6 3/3 x 3 1/4 = 19 is option B: 19 ÷ 3 1/4 = 6 3/4.

Explanation:

To find the equation that is equivalent to 6 3/3 x 3 1/4 = 19, we need to perform the operations on both sides of the equation. Let's start by simplifying the multiplication on the left side:

6 3/3 x 3 1/4 = 19

19/1 = 19

Now, let's examine each option:

A. 3 1/4 ÷ 19 = 6 3/4: This equation does not give us an answer of 19, so it is not equivalent.

B. 19 ÷ 3 1/4 = 6 3/4: This equation does give us an answer of 19, so it is equivalent.

C. 3 1/4 ÷ 6 3/4 = 19: This equation does not give us an answer of 19, so it is not equivalent.

D. 6 3/4 ÷ 3 1/4 = 19: This equation does give us an answer of 19, so it is equivalent.

Therefore, the equation that is equivalent to 6 3/3 x 3 1/4 = 19 is option B: 19 ÷ 3 1/4 = 6 3/4.

To simplify 12/84 find the greatest common factor, the greatest factor shared by both numbers.  In this case, it is 12 itself.  Divide both sides by 12 to get 1/7.

Jeff hikes 1/2 mile every 15 minutes,or 1/4 hour.Lisa hikes 1/3 miles every 10 minutes, or 1/6 hour.How far do they each hike in 1 hour ?2 hour?

Answers

Answer: They hike 30 miles and 20 miles in 1 hour respectively and they hike 60 miles and 40 miles in 2 hours respectively.

Step-by-step explanation:

Since we have given that

Number of mile Jeff hikes in every 15 minutes = (1)/(2)

As we know that

1 hour = 60 minutes

So, number of mile Jeff hikes in every 1 hour = (1)/(2)* 60=30\ miles

number of miles Jeff hikes in every 2 hours = 30* 2=60\ miles

Number of miles Lisa hikes in every 10 minutes = (1)/(3)

Number of miles Lisa hikes in every 1 hour = (1)/(3)* 60=20\ miles

Number of miles Lisa hikes in every 2 hours = 20* 2=40\ miles

Hence, they hike 30 miles and 20 miles in 1 hour respectively and they hike 60 miles and 40 miles in 2 hours respectively.

jeff hikes 1 mile every 30 min so in one hour he hiked 2 miles and in 2 hours he hiked 4 miles. im sorry but im not sure about lisa

Daniel is making a cube using blocks. The cube is solid and has no holes.How many cubes did Daniel use?



A.
81

B.
243

C.
486

D.
729

Answers

This answer uses NMF, which can be found out about in my profile:

We know that the length has to equal the width and height. This means that the amount of cubes used in total has to be the cube (power of 3) of the side length.

The answer is
floor#({3}√{x}) = {3}√{x}
where x is your possible answers and the statement is true.

If we do x = 81, then we can do
{3}√{81} ≈ 4.33
floor#(4.33) ≠ 4.33
therefore the answer is not 81

x = 243:
{3}√{243} ≈ 6.24
floor#(6.24) ≠ 6.24

x = 486:
{3}√{486} ≈7.86
floor#(7.86) ≠ 7.86

x = 729:
{3}√{729} = 9
floor#(9) = 9
Because they are equal, the number of cubes used is 729.
