Answer:

No

Step-by-step explanation:

To solve this equation you need to divide 975 by 72. After you divide those 2 numbers, you get 13/5... This means, that the scientist does not have enough distilled water for all 15 experiments. She only has enough for 13 experiments since about 1/2 is not a full amount.

Ilia_Sergeevich [38]

Answer:

t = 1/2 ÷ 1/4

t = 2 hours

Step-by-step explanation:

Time spent watching movies = 1/2 of an hour

This accounts for 1/4 of the total time thei spend at mount rushmore.

1/2 = 1/4t

Where t = total time they spent at mount rushmore (hours)

1/2 = 1/4t

Determine the equation to find t

t = 1/2 ÷ 1/4

= 1/2 × 4/1

= 4 / 2

= 2

t = 2 hours

The equation below was identified as representing the relationship between dollars spent
ankoles [38]

Answer:

The company should spend 20,000 dollars on advertising in order to avoid losing money.

Step-by-step explanation:

You know that the relationship between dollars spent on advertising X, and earnings P, for a particular company is:

P= 1.5* X -30,000

You want to know how much money the company should spend on advertising so that the company doesn't lose money. That is, the company has no losses but no profits. So this means that P must have a value of 0.

So, replacing:

0= 1.5*X - 30,000

Solving:

30,000= 1.5*X

30,000÷ 1.5= X

20,000= X

<u><em> The company should spend 20,000 dollars on advertising in order to avoid losing money.</em></u>
