Answer:
638
Step-by-step explanation:
The total number of responses is the value of a geometric series with first term 70 and common ratio 1-10% = 0.90. That sum is given by the formula ...
Sn = a1·(1 -r^n)/(1 -r)
where r is the common ratio, n is the number of terms, and a1 is the first term.
The sum of n=23 terms of the series with a1=70 and r=0.9 is ...
S23 = 70·(1 -0.9^23)/(1 -0.9) = 700(1 -0.9^23) ≈ 638
The model predicts 638 total responses over the first 23 days.
the answer is d. it is a false statment because -15 is less than -12
explanation -15 is less that -12
hope this helps
you need to make the fraction to 100
100/25=
you multiply 20x4
80
Answer:
25
Step-by-step explanation:
Let's call that number x
100/x = 4 now multiply both sides by x to get rid of fraction
100 = 4x divide both sides by 4
25 = x
This problem should not give you too much difficulty. The area of a triangle is (LxH)/2. The area of a rectangle is LxH. Calculate the area of each triangle and the three rectangles.
When added together, you should get 75.75cm².
I would show the work for you, but just work through it slowly, and you should get the same thing.
