The art museum had a total of 224 visitors on Tuesday. Visitors older than 18 paid $12 for admission. Visitors 18 years or younger paid $8 for admission. The museum collected a total of $2,520. How many visitors were 18 or younger?

Answers

Given:
total of 224 visitors
older than 18 paid $12
18 and below paid $8
total collection 2,520

Let l be visitors older than 18 and m be visitors 18 and below.

l + m = 224
12l + 8m = 2,520

l = 224 - m
12(224 - m) + 8m = 2520
2688 - 12m + 8m = 2520
-4m = 2520 - 2688
-4m = -168
m = -168/-4
m = 42 number of visitors 18 and below.

l = 224 - m
l = 224 - 42
l = 182 number of visitors older than 18.

12(182) + 8(42) = 2520
2184 + 336 = 2520
2520 = 2520

The school printer has purchased a new color printer that can produce 75 pages in 5 minutes. If the printer were to print only 1 minuets, how many pages would it produce?

Answers

15 pages

Step-by-step explanation:

This is a fairly simple problem meaning it has very few steps. If it makes 75 pages in 5 minutes you need to find out what the PPM or Page Per Minute is.

To find that you simply divide 75 by 5 and get 15 and in one minute the printer prints 15 pages.

Hope it will help :)

Final answer:

The number 1.452 x $10^3$ in scientific notation can be written as the ordinary number 1452 by shifting the decimal point three places to the right.

Explanation:

The given number is in scientific notation and we need to convert it into an ordinary number. It uses a decimal number between 1 and 10 (inclusive) and multiplies it by a power of 10.

In the given expression 1.452 x $10^3$ , the $10^3$ means we need to shift the decimal place in 1.452 three places to the right. This is because the exponent is positive. After shifting, the number becomes 1452.
