The length of each base of a trapezoid is shrunk to one-third its original length and the height of the trapezoid is tripled.
Lisa claims that the area of the new trapezoid is one-third the area of the original trapezoid.
Which expression best uses the dimensions of the new trapezoid to compare its area to the area of the original trapezoid in order to
determine if Lisa's claim is accurate?
A
lh + b) 3h
C С
3(02+)31
D

9514 1404 393

Answer:

  A

Step-by-step explanation:

The formula for the area of the original trapezoid is ...

  A = 1/2(b1 +b2)h

Using 1/3 the base length and 3 times the height, the area of the new trapezoid is ...

  A = 1/2((1/3b1) +(1/3b2))(3h)

  = (1/2)(1/3)(b1 +b2)(3h)

  = 1/6(b1 +b2)3h . . . . . . . . matches choice A

Williams is planning a party. He spent 110.74 to buy 9.8 pounds of candy for favors. What was the cost per pound of the candy

1. These are the first sentences in the short story, "The Gift of the Magi," by O. Henry:

"One dollar and eighty-seven cents. That was all. And sixty cents of it was in pennies."

Model the scenario with an equation. Let q be the number of quarters, d be the number of dimes, and n be the number of nickels.

25 q + 10 d + 5 n + 60 = 1.87
0.25 q + 0.10 d + 0.5 n + 0.60 = 187
q + d + n + 60 = 187
25 q + 10 d + 5 n + 60 = 187

2. These are the first sentences in the short story, "The Gift of the Magi," by O. Henry:

"One dollar and eighty-seven cents. That was all. And sixty cents of it was in pennies."
