Answer:
Answer:
D ) 154
Step-by-step explanation:
a 1 = 13, d = 3;
S n = n/2 * ( a 1 + a n )
a 7 = a 1 + 6 d = 13 + 3 * 6 = 13 + 18 = 31
S 7 = 7/2 * ( 13 + 31 ) = 7/2 * 44 = 154

it will go onto its self 5 time
Step-by-step explanation:
The use of sine and cosine could give you the angle measuments of the triangle, along with the use of tangent. Not only could it give you the angle measurements but the lengths of the sides.
Last week, the Glee Club made 437 flowers. They made 322 more this week than last week. So this could be shown in this case as 437 + 759 (since 437 + 322 = 759). This equals 1,196 flowers. To find the remaining number of required flowers, we could represent this equation as 1,196 + x = 1,250, with x representing the number of flowers still needed. Since 1,250 - 1,196 = 54, they still need to make 54 paper flowers for their parade float. Substituted back into the equation, it would look like this:
1,196 + 54 = 1,250.
