Answer:
25150
Step-by-step explanation:
First, we have to see that this is an arithmetic sequence... since to get the next element we add 5 to it. (a geometric sequence would be a multiplication, not an addition)
So, we have a, the first term (a = 4), and we have the difference between each term (d = 5), and we want to find the SUM of the first 100 terms.
To do this without spending hours writing them down, we can use this formula:
If we plug in our values, we have:
S = 50 * (8 + 495) = 50 * 503 = 25150

THE MEDIAN IS THE MIDDLE NUMBER IS 86 AND 90
Answer:
BC = 60
Step-by-step explanation:
3X + X = 80 <---- X = BC
3X + X = 4X
4X = 80 <---- DIVIDE BOTH SIDES BY 4
4X ÷ 4 = X
80 ÷ 4 = 20
20 × 3 = 60
Answer: approximately 5.5814 calories
==================================
We start off with this ratio
4.3 ounces : 24 calories
Divide both parts of the ratio by 4.3 so that we end up with 1 ounce on the left side
4.3 ounces : 24 calories
4.3/4.3 ounces : 24/4.3 calories
1 ounce : 5.5814 calories
This value is approximate to four decimal places.
