Given Info: "The dashed triangle is the image of the solid triangle"
So the "before" is the large solid triangle and the "after" is the smaller dashed triangle.
The horizontal side of the solid triangle is 15 units. The corresponding side for the dashed triangle is 3 units. Dividing the two values gives: 3/15 = 1/5 = 0.2
Make this value negative. The reason why is due to the fact that we have a sort of reflection going on as we're scaling down the figure.
So the final answer is -0.2
Answer:
Step-by-step explanation:
Given
<em>Decimal Grid = Hundredths</em>
To solve for each:
We have:
For Amber:
For Grace:
This means that Grace shaded 60 of the hundredth models.
Decimal shaded is:
For Marsha:
Multiply this by 100, to get the number of shaded
This means that Marsha shaded 170 of the hundredth models.
Decimal shaded is:
A, B and C working together will finish same piece of work in 10 days
A can do a piece of work in 20 days. That is A is doing the work at a rate of 1 / 20. Therefore
B = 1 / 30
C = 1 / 60
A, B and C working togehter their rate will be added together =
A + B + C = 1 / 20 + 1 / 30 + 1 / 60 = 1 / 10
so they can work together to finish same piece of work in 10 days
