The area of a polygon is <span>A=perimeter×apothem÷2
</span>you know <span>A=500</span><span> and apothem = 10\
</span>
<span>500=<span><span>P×10/</span>2
</span></span>you should get that the perimeter is 100<span> from the algebra
</span>
<span>part 1 is 100, the perimeter is 100
</span>
The 100 * 7.95
1.89 + 3.72 = 5.61
10.75 - 5.61= 5.14
5.14 x 100= 514
0.64 x 100= 64
(You can skip out the multiplying by 100 but doing this step makes it easier to do without a calculator)
514/64= 8.3
Round the number down to 8 and this is your answer.

Answer:
The test statistic is -1.00
Step-by-step explanation:
Test statistic (Z) = (sample mean - population mean) ÷ sd/√n
sample mean = 38.8miles/gallon, population mean = 39miles/gallon, sd = 2.2miles/gallon, n = 120vans
Z = (38.8 - 39) ÷ 2.2/√120 = -0.2 ÷ 2.2/10.95 = -0.2 ÷ 0.20 = -1.00 (to 2 decimal places)
Answer:
3/4x-6=42
x=64
Step-by-step explanation:
Let the number of students be x hence 3/4 of this number will be 3/4x
Since the number was 42 if they were 3/4x less six, it means minus six hence
3/4x-6=42
Therefore, the equation will be
3/4x-6=42
Solving the equation
3/4 x=42+6=48
3/4x=48
X=62
