Answer:

D. $25,400

Step-by-step explanation:

Let x represent the score during December.

We have been given that during 1 months of a recent year, a certain charitable organization received an average (arithmetic mean) of $20,600 per month in donations.

The total score for 11 months would be 11\times 20,600=226600.

We can set our given information in an equation as:

\text{Average}=\frac{\text{Sum of all data points}}{\text{Total number of data points}}

\frac{226,600+x}{12}=21,000

\frac{226,600+x}{12}*12=21,000*12

226,600+x=252,000

226,600-226,600+x=252,000-226,600

x=25,400

Therefore, the organization received $25,400 in donations during December and option D is the correct choice.

A skydiver is falling at approximately 28 feet per second. Find the skydiver's change in altitude
Free_Kalibri [48]

9514 1404 393

Answer:

  -140 feet

Step-by-step explanation:

The relation between speed, distance, and time can be written ...

  distance = speed × time

  distance = (28 ft/s)(5 s) = 140 ft

In 28 seconds, the skydiver changed position by 140 feet. Since the direction is presumed to be down (falling), the change in altitude is -140 feet.

stealth61 [152]

Answer:

Total cost of Theo's purchases in terms of k and p=2.49(k + p) + 5.99

Step-by-step explanation:

Cost of k key chain=$2.49

Cost of p photo frames=$2.49

Cost of a T-shirt=$5.99

Total cost of all items=cost of k key chain + cost of p photo frame + cost of The shirt

=2.49k + 2.49p + 5.99

Factorise

2.49 is common to both k and p

=2.49(k + p) + 5.99

Total cost of Theo's purchases in terms of k and p=2.49(k + p) + 5.99

Carol has only 20p and 10p coins in her purse she has three times as many 20p coins and 10p coins if Carol has ?4.20 altogether,
irinina [24]

Suppose that Carol has x 10p coins in her purse. Since she has three times as many 20p coins as 10p coins, then she has 3x 20p coins in her purse.

x coins of 10p value $0.10x and 3x coins of 20p value $0.60x.

In total this amount of money is $(0.10x+0.60x)=$0.70x that is exactly $4.20. Thus, you get the equation

0.70x=4.20.

Solve it:

x=\dfrac{4.20}{0.70}=6.

Carol has 6 coins of 10p and 3·6=18 coins of 20p.
