Answer(ii) is correct to win 1 is the number of heads
Total: 54
Boys: 36
Girls: x
54 - 36 = x
x = 18
There would be 18 girls at the swim meet
The area of a trapezoid is found by averaging the bases and multiplying the height. to average the bases, you take 22ft + 14ft to get 36ft and then divide it by 2 since there are 2 numbers to average to get 18ft. Then you just multiply that by 8ft to get your area of 144ft^2 (square feet).
Answer:
Step 2: 36 + 21 = 57
Step 3: (36 + 21) x 2= 114
Step 4: 36 + 36 + 21 + 21 = 114
Step-by-step explanation:
<span>Let x= measure of sides that have common length
then from "the third side measures 5m less than twice the common length."
2x-5= third side
.
Because they gave us the perimeter we have:
11 = x+x+2x-5</span><span>11 = 4x-5
16 = 4x
4 m = x
.
third side:
2x- 5 =2(4)-5 = 8-5= 3m</span>
Length answers:
4m, 4m, and 3m
