Answer : The 5th day = 3 Celsius
Explanation:
the average of the first 4 day is 8
Which mean the combine temp on the first 4 day is 8 x 4 = 32
Now on the first 5 day the average temp is 7
Then the combine temp on the first 5 day is 7 x 5 = 35
Find the 5th day
4 days combine temp + 5th day = the combine temp of 5 days
32 + 5th day = 35
5th day = 35-32
5th day temp = 3C
Answer:
B. 14.075
Step-by-step explanation:
Answer:
Your answer is 12
Step-by-step explanation:
Start by multiplying 9 and 1 1/2. Then add 7 1/2. Now divide by 1 3/4
Using a system of equations, it is found that since 20 child bikes and 6 adult bikes would require more testing than the allocated time, it is not possible to build this amount.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable c: number of child bikes.
- Variable a: number of adult bikes.
Each child bike requires 4 hours to build, as do each adult bike. The company has 100 hours of testing, hence:
4c + 4a = 100.
c + a = 25.
With 20 child bikes and 6 adult bikes in a week, we have that c = 20, a = 26, hence:
c + a = 26
20 child bikes and 6 adult bikes would require more testing than the allocated time, it is not possible to build this amount.

Answer:
162.24 ft
Step-by-step explanation:
So you first find the area of one side.
5.2 x 5.2 = 27.4
Then you times it by 6, because a cube has 6 sides.
27.4 x 6 = 162.24 ft
