Over the summer, Jackie played video games 3 hours per day. When school began in the fall, she was only allowed to play video games for half an hour per day. What is the percent decrese? Round to the nearest percent.

Answers

Answer 1

Answer: I believe if I am correct it would be 60% because 30 min goes into 3 hours 6 times so let's say 6 hours is a hundred percent 30 min is like 10 percent so via it would be a 60 percent drop tell me if I am wrong please would like to know the right way for this problem

Answer:

$36\pi$

Step-by-step explanation:

Since the radius of a circle is half of the diameter, the radius of this one is 12/2=6 feet. The formula for the area of a circle is $\pi r^2$ , which in this case is $\pi \cdot 6^2=36\pi$ . Hope this helps!

Answer:

36π

Step-by-step explanation:

A = π $r^(2)$

= π $(6)^(2)$

= π x 36

= 36π

. Priya changed the rate at which water flowed through thefaucet. Write an equation that represents the relationship of

w and t when it takes 3 minutes to fill the cooler with 1

gallon of water.

Answers

Answer:

w = (1/3)*t

Step-by-step explanation:

There is a proportion between the amount of water (w) and the time elapsed (t). For every 3 minutes a gallon of water is added to the cooler, this means that in 6 minutes 2 gallons will be added, in 9 minutes 3 gallons, and so on. Therefore, the relationship is:

w/t = 1/3 = 2/6 = 3/9

where t is in minutes and w in gallons

Rearranging gives:

w = (1/3)*t

We can check this equation replacing t with, for example, 6 minutes, to get:

w = (1/3)*(6) = 2 gallons

Final answer:

The question is mathematical, dealing with rates and linear equations. It seeks to establish a relationship between the volume of water (w) and time (t) when filling a cooler. The equation representing this relationship is w = t/3.

Explanation:

The subject of this question is in the field of Mathematics, specifically dealing with the concept of rates and linear equations. The question is asking to establish a relationship between the volume of water 'w' (in gallons) and the time 't' (in minutes). This relationship is a rate, and in this case, 1 gallon of water is filled in 3 minutes.

Therefore, the equation representing this relationship is: w = t/3.

In this equation, 'w' represents the volume of water in gallons, and 't' represents time in minutes it takes to fill the cooler. So, for example, if you want to fill the cooler in 6 minutes, you would substitute 6 for 't' in the equation to find out how much water you would have: w = 6/3 = 2 gallons.

Rewrite
16/9
as a mixed number.

Answers

The 16/9 can be written as the mixed number 1 7/9. This shows that the fraction represents one whole unit and an additional seven-ninths of another unit.

To rewrite the fraction 16/9 as a mixed number, we need to find the whole number part and the fractional part.

Step 1: Divide the numerator (16) by the denominator (9). This will give us the whole number part.

16 ÷ 9 = 1 with a remainder of 7

Step 2: Write the whole number part (1) followed by the fractional part, which is the remainder (7), over the original denominator (9).

So, the mixed number is 1 7/9.

The mixed number 1 7/9 represents the fraction 16/9. The whole number part (1) indicates that there is one whole unit, and the fractional part (7/9) represents an additional seven-ninths of a unit.

In conclusion, 16/9 can be written as the mixed number 1 7/9. This shows that the fraction represents one whole unit and an additional seven-ninths of another unit.

#SPJ6

To find the answer, to convert a improper into mixed, first take the denominator (9) and find how many times it can go into the numerator (16) FULLY. The answer is 1 time. 1 is the whole number. Then whatever is leftover is the new numerator, and the old denominator is the same. So your answer is 1 7/9
