Answer: 12 x 8
Step-by-step explanation: The other three are not the basic multiplication facts from 0 - 12.
Answer:
Step-by-step explanation:
Unfortunately it's not clear what you mean by 6 Σ 2 3(0.5)^n-1. I am going to assume that you mean summing up from n = 2 to n = 6 of the expression 3(0.5)^(n-1). Note that the "n-1" must be enclosed in parentheses.
a(2) = 3(0.5)^(2 -1) = 3(0.5) = 1.5
a(3) = 3(0.5)^(3 -1) = 3(0.5)^2 = 0.75
a(4) = 3(0.5)^(4 -1) = 3(0.5)^3 = 0.375
a(5) = 0.1875
a(6) = 0.09375
Sum these up to find the final answer.

Answer:
56.81 seconds is the team’s best time for the race
Step-by-step explanation:
Here, we want to give the team’s best time for the race
from the question, we should understand that the best times are the smallest in values since it is a race
The smallest time here is 56.81 seconds and thus that is the team’s best time for the race
Answer:
x = 13
Step-by-step explanation:
- 3 (x + 4) + 15 = 16 - 4x
- 3x - 14 + 15 = 14 - 4x
- 3x + 4x = 14 + 14 - 15
x = 13
It is 77/10 because you have to multiply the whole number by the denominator and that gives you 70. Then you add the value of the numerator to 70, which is 77. so the answer is 77/10
