Answer:
4 times more
Step-by-step explanation:
80/20=4
Answer:
1/5
Step-by-step explanation:
For Monday
The fraction of homework Chain completed =
40% of her homework
= 40% = 40/100
= 2/5
For Tuesday
The amount of home work left =
= 1 - 2/5
3/5
The fraction of homework Chain completed on Tuesday = 2/3
= 2/3 Of 3/5
= 2/3 × 3/5
= 2/5
Let the total complete homework be represented by 1
Hence:
The Fractional part of her homework left for her to complete after Tuesday =
1 - (2/5 + 2/5)
Lowest common denominator is 5
= 1 - (2 + 2/5)
= 1 - (4 /5)
= 1/5
Answer:

149 engines in 9th year
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
From a look at the photo and the data plot can be represented by the function, so we can pick 2 points in our given graph
- (x1, y1) = (2,60)
- (x2, y2) = (5,99)
The standard form of a linear equation is:
y = mx + b where:
- m is the slope
- b is the y-intercept
We know the slope of the function can be found as following:
so in this situation we have:
<=> 
=> y = 13x + b (1)
Because the line goes through point (2,60) so we substitute it into (1):
60 = 13*2 + b
<=> b = 60 - 26 = 34
=> y = 13x + 34
Now we will substitute x=9 to find the engines produced by company in 9th year as:

Hence, the company will produce 149 engines in 9th year
