Remark
You can use a formula to get the right answer. Otherwise you will use a lot of paper adding 100 numbers together.
Givens
A = 1
L = 100
n = 100 numbers to be added together. There are 100 numbers between 1 and 100 numbers inclusive.
Formula
Sum = (A + L)*n/2
Solution
Sum = (1 + 100)*100/2 Substitute in the givens. Add what is inside the brackets
Sum = (101) * 100 / 2 Divide by 2
Sum = 101* 50 Multiply
Sum = 5050 Answer
Answer:
4. No because 2×4=8 but 5×4 doesn't equal 18
Answer:
Step-by-step explanation:
Distance Janie walked
First add canvert 1/4 by multiplying by 2/2 to get a commmon denominator.
Now find a common denominator for 3/5 and 5/8 by multiplying 3/5 by 8/8 and 5/8 by 5/5.
Now add them.
miles
You can also convert all to decimals and add.
3/5 = .6
1/4 = .25
3/8 = .375
.6 + .25 + .375 = 1.225
Also 1 = 1.225
Answer:
Pace in miles per hour =
Step-by-step explanation:
Distance ran in 33 minutes =
33 minutes =
1 minute =
60 minutes =
60 minutes = miles
