Answer:
A) 9^7
Step-by-step explanation:
For this type of problem, since they both have the same base, you can add the exponents together and have the base remain the same. So you would have 5+2 = 7.
Now, to find how many people are not there, all you have to do is subtract the amount of seats and the people there.
112- 70= 42
Now since there are 7 seats per row and 42 is divisible by 7, you can divide 42 by 7.
42÷7= 6
So, 6 rows were empty.
Answer:
the answer is c
Step-by-step explanation:
Area of a triangle = 1/2 x base x height
Area = 1/2 x 8.7 x 8.6
Area = 37.41 square feet
0.2, 0.3, 0.4, 0.5 if 0 doesnt count then exclude 0.2.
-0.2 + 0.2 = 0
-0.2 + 0.3 = 0.1
-0.2 + 0.4 = 0.2
-0.2 + 0.5 = 0.3
