Answer:
B BC=EF
Step-by-step explanation:
You know that angle B=angle E and that angle C=angle F
You need to knows that segment BC=segment EF because they are between the known angles (ASA, Angle Side Angle).
Start by defining your variables. Let the length be L and the width W. Note that W = 2L/3.
Use the Perimeter formula: P = 2W + 2L. Substituting,
P = 2[2L/3] + 2L, or P = 4L/3 + 2L, or P = 4L/3 + 6L/3 = 10L/3 = 210 feet
Then 10L = 630 feet, and L = 63 feet. Thus, W = 2L/3 = 2(63 feet)/3 = 42 feet.
Answer:
85.6%
Step-by-step explanation:
To get two overall performance of Harry, we need to calculate his average score.
Average is also known mean score.
Mean = sum of the score/Total math subjects offered
Mean = 95+ 90+85+40+100+100+85+90/8
Mean = 685/8
Mean = 85.6
Hence her overall performance is 85.6%
The measure of central tendency used is 85.6%
