Answer:

4 times as fast

Step-by-step explanation:

To determine how many time as fast, take the rate up and divide by the rate down

63 minutes

--------------------

15 minute 45 seconds

But we need to be all in the same units  so change second to minutes by dividing by 60

63 minutes

--------------------

15 minute 45/60 minutes

63 minutes

--------------------

15.75  minute

4 times

Answer:

4 times as fast

Step-by-step explanation:

We need to first convert everything to the same units. Let's change it to seconds. There are 60 seconds in a minute, so 63 minutes is 63 * 60 = 3780 seconds and 15 minutes, 45 seconds is 15 * 60 + 45 = 945 seconds.

Now, in order to find how many times as fast the rate going up was than the rate going down was, we divide the ascending rate by the descending rate:

3780 / 945 = 4

The answer is thus 4 times as fast.

Help!<br> What would d be?
Oxana [17]

Answer:

d = 17.5499287748 inches or 17.5 inches to 1 decimal place

Step-by-step explanation:

find the diagonal line passing through the middle of the bottom rectangle:

a² + b² = c²

10² + 8² = c²

100 + 64 = 164

c² = 164

c = √164

c = 12.8062484729

find d:

a² + b² = c²

12² + 12.80624847298² = c²

144+ 164 = 308

c² = 308

c = √308

c = 17.5499287748

therefore d = 17.5499287748 inches or 17.5 inches to 1 decimal place

Viefleur [7K]

Answer:

11 games

Step-by-step explanation:

17+6=23

23/2=11.5

Victoria can play 11 games. You'd usually round up, but in this case you can't play half a game so she'll play 11 games and have one quarter leftover.

Comparing Leaking Pool Problem
Blababa [14]

Answer:

<em>Pool 1 leaks faster than pool 2.</em>

Step-by-step explanation:

<u>Rates of change</u>

The rate of change (ROC) is a measure that compares two quantities, usually to know how fast one variable changes in time.

We are given two rates of change for two pools that are leaking. The first one loses 2/3 gallon in 15 minutes, and the other loses 3/4 gallon in 20 minutes.

To compare them, we are required to express time in hours. Recall one hour has 60 minutes, or equivalently, one minute has 1/60 hours. Converting both times, we have:

15 minutes = 15/60 = 1/4 hours

20 minutes = 20/60 = 1/3 hours

Now compute both rates of change:

Pool 1:

\displaystyle ROC_1=\frac{2/3}{1/4}=\frac{8}{3}\approx 2.67\ gal/h

Pool 2:

\displaystyle ROC_2=\frac{3/4}{1/3}=\frac{9}{4}= 2.25\ gal/h

Comparing both ratios, it's clear pool 1 leaks faster than pool 2.
