Answer:

Step-by-step explanation:

4/3 ÷ 2 = 2/3.

2/3 water waters 1/5 plants in the house.

2/3 x 5 = 10/3.

1/5 x 5 = 1.

10/3 = 3 1/3.

3 1/3 liters of water are needed to water all the plants in the house.

The function w=30-3/4n represents the weight w in pounds of the papers in tyrones newspaper delivery bag after he delivers n new
adoni [48]

Answer:

domain (−∞,∞)

range (−∞,∞)

n = 40 and it refers to the fact that after delivering 40 newspapers, there will be no paper left in the bag

Step-by-step explanation:

To find the zero, we equate the linear equation to zero

w = 30 - 3n/4

3n/4 = 30

3n = 120

n = 120/3

n = 40

What this mean in this context is that the the bag becomes empty after he has delivered 40 newspapers or we can say that the maximum number of papers the bag can take is 40

The range refers to the number on the y-axis

Here the range is (−∞,∞)

The domain refers to the x axis values

We have (−∞,∞)

Mike had 280 dollars to spend on 8 books.After buying them he had 16 dollars. How much did each book cost?
adell [148]
Well, you can't really determine the price of 1 book, but you can find out the average cost.

280 - 16 = 8x (x = cost of 1 book)
264 = 8x
264/8 = 8x/8
33 = x

So the average cost of one book is 33$( A little expensive if I do say so myself)
Hope this helped!

Kathie spent $38 on a fruit salad. She bought bananas, mangoes, and pineapples. Bananas cost $1 per pound, mangoes cost $2 per p
devlian [24]

Answer: X * 1 + Y * 3 + Z * 2 = 45

Step-by-step explanation: we will use bananas, apples and mangoes as the unknowns of the equation.

The value that you multiply to the unknowns will be multiplied by the price that corresponds to it.

These 3 products must be added to result in the total value that is 45.

X * 1 + Y * 3 + Z * 2 = 45

A small school has three foreign language classes, one in French, one in Spanish, and one in German. How many of the 34 students
serg [7]

Answer:

Statement 1 is sufficient

And the solution is 12

Statement 2 is insufficient

Step-by-step explanation:

Statement 1 : There are 27 students enrolled in the French class,and 49 students enrolled in either the French class,the Spanish class,or both of these classes.

Let S = number of Spanish-only students

F = number of French-only students

B = number of students taking both, which is the number the prompt question wants.

Given that;

S + B = 34

F + B = 27

S + F + B = 49

The equations above are from the question and statement 1.

Solving for B, we have;

(S + B) + (F + B) = 34 + 27

B + S + B + F = 61

S + B + F = 49

B + 49 = 61

B = 61 - 49 = 12

Therefore statement 1 is sufficient to give a specific and numerical solution to the question.

Statement 2: One half of the students enrolled in the Spanish class are enrolled in more than one foreign language class.

The statement 2 states that half of the students enrolled in the Spanish class are also enrolled in one foreign language but did not specify which proportion or fraction of them are enrolled in german or french therefore a specific numerical solution cannot be derived from this statement.

Hence, statement 2 is insufficient.
