Answer:
$2.40
Step-by-step explanation:
Zack needs a total of 4 feet of balsa wood which costs $0.05 per inch.
Note that 4 feet = 48 inches.
The overall cost will be ($0.05/in)(48 in) = $2.40
So we need to find the sum of the first 5 terms.
You have told me that the first term is 10 meters, and that r = 0.5 per term.
With this knowledge, we can use the formula s_n=a₁((1-r^n)/(1-r)).
Plugging in the terms that we know...
s₅=10((1-0.5⁵)/(1-0.5))
s₅=10(0.96875/0.5)
s₅=10(1.9375)
s₅=19.375
With s₅, we can determine that the ball has traveled a total of 19.375 meters after 5 bounces.
What do you want us to answer?
Answer:
L8
Step-by-step explanation:
We turn that upside-down
86 '? '88 '89 '90 '9I
Then obviously we can tell that ? is to be replaced by 87
86 '87 '88 '89 '90 '9I
Then we turn it back right-side up again, and we have:
I6, 06, 68, 88, L8, 98
Answer: L8
Hope this helps ;)
4x + 8 = 4x +8
This means that there are in fine solutions since the expressions are equaled to each other.
