3 = $9.81
1 = $?
To find this you have to do 9.81/3.
Hope this helps and have a nice day!!
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:
7
Step-by-step explanation:
If each pack of green beans makes 12 bowls of soup then it would take 7 packs to make 84. 84/12=7
Answer:
Perimeter of the rectangle = 96 meters.
Step-by-step explanation:
Let the width of the rectangle = K
So, the length of the rectangle = 5K
Area = 320 sq meters
Now, Area of a Rectangle = Length x Width
⇒ 320 = K x 5K
or,
So, the vlue of K = 8 or, K = -8
But as K represents a length hence, K ≠ -8
So, the <u>width of the rectangle = 8 meters</u>
and the<u> length of the rectangle = 8 x 5 = 40 meters</u>
Now, Perimeter = 2(length + width)
= 2(8 + 40) = 96 meters.
So, the perimeter of the rectangle = 96 meters.
Let
and
. By the product rule,

By the power rule, we have
and
, but
are functions of
, so we also need to apply the chain rule:


and we have


So we end up with

Replace
to get everything in terms of
:

We can simplify this by factoring:
