To find a surface area of a cube you want to find the area of ONE side first. Since we know that the area of a square is s^{2}, and we know that the side is 8.5, we can square it.

8.5^{2} = 72.25

Since the area of one side is 72.25, and the number of sides in a cube is 6, we should multiply 72.25 by 6

=433.5

Your answer for the first problem should be 433.5 if I am not mistaken.

The second problem simply asks to write the fraction as a repeating decimal

17/7 = <span>2.428571428571

We can see that the decimal digits of 428571 repeats, you would put the bar over it. Good luck!</span>

Safety regulations require that the time between airplane takeoffs (on the same runway) will be at least 3 minutes. When taking
Alenkinab [10]

Answer:

1.96 planes

Step-by-step explanation:

The computation of the number of planes is shown below:

As we know that

System Inventory  is

= Flow rate in the system × Throughput time

where,

Flow rate is

= Frequency of taken off

= 16 planes ÷ hour

= 16 ÷ 60 Planes per minute

Throughput time  is

=  runway waiting time + runway Run time

= 33 seconds +  6 minutes × 60 seconds + 48 seconds

= 441  seconds

= 441  per 60 seconds

Therefore the number of planes is

= \frac{441}{60} \times \frac{16}{60}

= 1.96 planes

Janae's savings account has $50 on September 19. If she plans to save $5 every day, how much money will Janae have in her saving
Akimi4 [234]

Janae will have $ 95 in her account after 10 days.

<h3>What is an Arithmetic Progression?</h3>

A sequence of numbers that has a fixed common difference between any two consecutive numbers is called an arithmetic progression (A.P.)

Given,

Amount in Janae's account = $ 50

Amount she wishes to save for 10 days = $ 5

This scenario models an arithmetic progression(A.P)

In an A.P,

a _n = a + (n-1)d

where a _n = nth term, a is the first term, n is the no. of terms and d is the common difference.

In this question, a = 50, n = 10, d = 5 and we have to find out a _n

Therefore, a _n = 50 + (10-1)x5

                         = 50 + 45 = 95

Answer:- Janae will have $ 95 in her account after 10 days.
