Answer:
C. 72 sorry if its wrong
Step-by-step explanation:
trapezoid formula : A= 1/2h(B+b)
plug in:
A= 1/2×6(10+14)
A= 3(24)
A= 72
Answer:
GI = 18; GE = 12; IE = 6
Step-by-step explanation:
The key to the question is to realize or find out what a centroid is and what it does. You can solve this question by knowing three things.
- The centroid is the meeting point of the three medians ( a median is a line that connects the midpoint of the side opposite a given vertex).
- The centroid divides the median in a ratio of 2:1. The longest segment is from the vertex to the centroid.
- The shortest segment is from the centroid to the midpoint of the side opposite the given vertex.
Point two is what you have to focus on.
GE/EI = 2/1
GE = 12 Given
Solution
GE / EI = 2/1 Substitute for the given
12 / EI = 2/1 Cross multiply
2*EI = 12 * 1 Simplify the right
2 * EI = 12 Divide by 2
EI = 12/2 Divide
Part Two
GI = EI + GE
GI = 6 + 12
GI = 18
EI = 6
Answer: 50
Find the area of the triangles then multiply by 2.
1/2 x 5 x 10 = 25
25 x 2 = 50
<span>The rate is the ratio and the unit rate is the rate when the denominator is 1.
$279 for 9 tickets.
=> rate = $279 / 9 tickets => unit rate = $ 31/ ticket
$18 for 6 volleyballs.
=> rate = $ 18 / 6 volleyballs => unit rate = $ 3 / volleyball
4 fouls in 20 minutes.
=> rate = 4 fouls / 20 minutes => unit rate = 0.2 fouls / minute
36 strikeouts in 54 innings.
=> rate = 36 strikeouts / 54 innings => unit rate = 0.67 strikeouts / inning
