did u need to add water or take water away to get from the 4 cup mark to the 1 liter mark

Answers

Answer:

You have to add water.

Step-by-step explanation:

I hope this helps! Have a great rest of your day!

The decision to add water to meet the 4 cup mark of water would be:

Yes, the water must be added.

What is volume?

"Volume" is described as the measure of a space that consists of length along with height and width.

Given that,

1 liter of water contains 1000 ml.

The capacity of a standard cup is 236.59 ml

If we take 4 cups, the total volume equals:

= 4 × 236.59

= 946.36 ml

Therefore, .23 cups or 53.64 ml of water would be required to be added.

the table shows the costs of different size jars of peanut butter. Which of the jars have the lowest unit rate?

Answers

Answer:

Step-by-step explanation:

Option C) 25-oz jar has the lowest unit rate

What is the unit rate?

Unit rate is the ratio of two different units, with the denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc

Given here the cost of a 12 oz jar is $3

so the unit rate of a 12 oz jar is = 12/3

                                                 = 4

similarly, the unit rates of all the jars from the given table are

 18 oz jar = 18/4.40

                = $4.09

25 oz-jar = 25/6.75

               = $3.703

32 oz jar = 32/8.25

               = $3.87

Hence the jar with the lowest unit rate is the 25 oz jar

Last month you purchased 6 individual songs and 1 albums for a total of $21.99.



This month you spent a total of $44.97 on 4 individual songs and 3 albums.

How much does each song and album cost

Answers

Answer:

Song =$1.50 Album =$12.99

Step-by-step explanation:

Lets assume Individual songs = x

albums=y

6x + y = 21.99-------- y= 21.99- 6x

4x + 3y= 44.97

Replace y in the second equation

4x+ 3(21.99-6x) = 44.97

4x +65.97- 18x = 44.97

14x= 21

x = 1.50

y= 21.99- (6*1.50)

= 12.99

If all the angles are equivalent (the same), the angles must each be 60 degrees because 60 times 3 angles equals 180.

Answers

Answer:

Sasha's grandma will need 48 square feet of fabric to sew the umbrella.

Step-by-step explanation:

Since Sasha's grandma is going to sew an umbrella for Sasha, which will be made of 4 identical triangles, if each triangle is 3 feet long and 4 feet high, to determine how many square feet of fabric does Sasha's grandma need, the following calculation must be done:

(3 x 4) x 4 = X

12 x 4 = X

48 = X

Therefore, Sasha's grandma will need 48 square feet of fabric to sew the umbrella.

Consolidate like terms:   2x = 2

Solve for x:  x = 1

Answer:

Step-by-step explanation:

To solve the equation, first you would multiply 3 times 2x and 3 times 1.  Then, you would write 6x plus 3 on the right side of the equation.  Then, you would subtract 3 from both sides of the equation.  You then will have 6x=4x+2.  Lastly, you would get an answer of x=1
