The top number is 4 and t =1, so you need to replace t with 1, find the answer, then replace t with 2 through 4, then find the sum of all of them:

6^1-1 = 6^0 = 1

6^2-1 = 6^1 = 6

6^3-1 - 6^2 = 36

6^4-1 = 6^3 = 216

Sum = 1 + 6 + 36 + 216 = 259

The answer is B.

Answer:

B 259

Step-by-step explanation:

The sum is 4 terms, so we need to add the 4 terms

Term 1: 6 ^ (1-1) = 6^0 = 1

Term 2: 6^ (2-1) = 6^1 = 6

Term 3: 6^ (3-1) = 6^2 = 36

Term 4: 6^ (4-1) = 6^3 =216

The sum is 1+6+36+216 = 259

Explain how you know 21/100 is greater than 1/5

Nataly_w [17]

This problem can be solved using equivalent fractions. The first step in resolving this problem is to realize that fractions are best compared when they both have the same denominator. In this case, I will choose to make that common denominator 100. There is no need to rewrite the fraction $\frac{21}{100}$ as the denominator for this fraction is already 100. The fraction $\frac{1}{5} =\frac{20}{100}$ . This is achieved by multiplying both the numerator and denominator by 20. Now that the two fractions have the same denominator, we can easily see that $\frac{21}{100}$ is greater than $\frac{1}{5}$ because it is greater than its equivalent fraction.

Can someone please help me outt

Answer:

ASA

Step-by-step explanation:

We can see that the triangle has at least one similar side and one similar angle. We can also see that the triangles meet at a point, so they must have the same angle at that point where they connect. So that leads us to our answer being ASA since they have two similar angles and one similar side. This is the answer that I think is correct just by looking at the image. I haven't take this class since last year, so this is simply from memory. Correct me if I am wrong!
