Answer:

127.75

Step-by-step explanation:

In this geometric series, it is clear that every number is half of the previous number. From that, we can continue on the series as shown below...

64+32+16+8+4+2+1+0.5+0.25

The series above is 9 total terms. We can add those together to get our answer.

64+32+16+8+4+2+1+0.5+0.25 = 127.75

Theo ate .7 of his candy bar. How many more tenths must he eat to finish the whole candy bar?

Julli [10]

Answer:

3 tenths

Step-by-step explanation:

One candy bar

= 1 candy bar

= 1.0, or 10 tenths (one tenth is 0.1)

If Theo eats 0.7 of a candy bar, we know that

1.0 - 0.7 = 0.3

0.3 = 3 *0.1 (one tenth)

Therefore, the answer is 3 tenths.

24. A tank can be filled by a pipe in 30 minutes and emptied by another pipe in 50 minutes. How many minutes will it take to fil

OleMash [197]

Answer:

75 minutes

Step-by-step explanation:

The rate at which the tank is filled up, F, and emptied, E, are respectively:

$F=\frac{V}{30}*60 = 2V/hour\\E=\frac{V}{50}*60 = 1.2V/hour$

Since V is the full volume of the tank, the time required to fill the tank if both pipes are open is given by:

$F-E=2V/hour-1.2V/hour = 0.8V/hour\\t= \frac{1}{0.8}=1.25\ hours = 75\ minutes$

It will take 75 minutes to fill the tank if both pipes are open.
