Solve 4 + (4 + 2) ÷ 4 x 4 - 22
| \(\frac{1}{4}\) | |
| \(\frac{2}{3}\) | |
| 1\(\frac{1}{2}\) | |
| 6 |
Use PEMDAS (Parentheses, Exponents, Multipy/Divide, Add/Subtract):
4 + (4 + 2) ÷ 4 x 4 - 22
P: 4 + (6) ÷ 4 x 4 - 22
E: 4 + 6 ÷ 4 x 4 - 4
MD: 4 + \( \frac{6}{4} \) x 4 - 4
MD: 4 + \( \frac{24}{4} \) - 4
AS: \( \frac{16}{4} \) + \( \frac{24}{4} \) - 4
AS: \( \frac{40}{4} \) - 4
AS: \( \frac{40 - 16}{4} \)
\( \frac{24}{4} \)

The greatest common factor (GCF) is the greatest factor that divides two integers.
If a car travels 325 miles in 5 hours, what is the average speed?
| 75 mph | |
| 50 mph | |
| 25 mph | |
| 65 mph |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)What is the distance in miles of a trip that takes 6 hours at an average speed of 20 miles per hour?
| 30 miles | |
| 175 miles | |
| 275 miles | |
| 120 miles |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)Solving for distance:
distance = \( \text{speed} \times \text{time} \)
distance = \( 20mph \times 6h \)
120 miles
If the ratio of home fans to visiting fans in a crowd is 5:1 and all 44,000 seats in a stadium are filled, how many home fans are in attendance?
| 24,000 | |
| 24,750 | |
| 36,667 | |
| 32,000 |
A ratio of 5:1 means that there are 5 home fans for every one visiting fan. So, of every 6 fans, 5 are home fans and \( \frac{5}{6} \) of every fan in the stadium is a home fan:
44,000 fans x \( \frac{5}{6} \) = \( \frac{220000}{6} \) = 36,667 fans.
