Since all of a squares sides are the same length, we can use 3.2 cm in the following equations:
P= 2L + 2W and A= L x W
P= 2(3.2) + 2(3.2) which is the same as P= 4(3.2)
P= 12.8 cm
A= 3.2 x 3.2
A= 10.24 cm^2
Answer:
Step-by-step explanation:
First turn them into improper fractions.
16 3/4 ----> 67/4
4 2/3 -----> 14/3
67/4÷14/3= ?
Now use keep, change, flip strategy
67/4×3/14= 201/56
Now simplify 3 33/56

Answer:
4 hours
Step-by-step explanation:
The general formula for distance, rate and time is:
d = rt, where distance is the product of rate multiplied by time
Given that one train is moving at a rate of 70 mph and one is moving at a rate of 62 mph in the opposite direction, the combined distance over time is equal to 528 miles. Using the variable 't' for time:
70t + 62t = 528
Combine like terms: 132t = 528
Divide both sides by 132: 132t/132 = 528/132 or t = 4 hours
Answer: 55 miles per hour
Step-by-step explanation:
Here is the complete question:
Seth's family plans to drive 220 miles to their vacation spot. They would like to complete the drive in 4 hours.
Find the average speed in miles per hour needed to make the trip in the desired.
From the question, Seth's family plans to drive 220 miles to their vacation spot and they would like to complete the drive in 4 hours.
Average speed is calculated as distance travelled divided by the time taken. This will be:
Speed = Distance/Time
Average speed = 220/4
Average speed = 55 miles per hour
