There are several information's already given in the question. Based on those given information's the answer can be easily deduced. 
Lateral area of the solid = 216 cm^2
Lateral edge of the solid = 9 cm
Let us assume the measure of the one side of the section = x
Then
216 = 4s * 9
216 = 36s
s = 6
From the above deduction, it can be concluded that the measure of the one side of the section is 6 cm. I hope that the answer has actually come to your help.

A waitress works 1.75 hours less in the afternoon than in the evening. If she works 5      1/8
gayaneshka [121]
Let x be the number of hours that the waitress works in the evening.

We know for our problem that she works 5 \frac{1}{8} in the afternoon and that she works <span>1.75 hours less in the afternoon than in the evening, so:
</span>x=5 \frac{1}{8} -1.75
<span>Since </span>\frac{1}{8} =0.125, we can rewrite our expression:
x=5.125-1.75
x=3.375

We can conclude that she works 3.375 hours in the evening, or expressed as a mixed fraction: 3 \frac{3}{8} hours.

A research organization wanted to estimate the average number of hours a college student sleeps per night during the school year
Alekssandra [29.7K]

Answer:

Step-by-step explanation:

Given given that

  • Lower confidence interval = 7.1
  • Upper confidence interval = 7.5
  • As such, We are 95% confident that it's somewhere between 7.1 and 7.5 hours per night

Average value = LCI + UCI /2 = 7.1 + 7.5 / 2

= 7.3hours per night, so we are 95% confident that it's somewhere between 7.1 and 7.5 hours per night which is eventually 7.3hrs per night.
