A=1/2bh
1st step: Multiply both sides by 2
2A=bh
2nd step: Divide both sides by h
2A/h=b
The equation is used to find the area of a triangle. The problem is asking to use this formula to find the formula to find the height of a triangle.
b=base of the triangle
h= height of the triangle
A= Area of the traingle
Although, if other geometry based problems use these problems it's just base and height and Area.
Answer:
10:18
Step-by-step explanation:
when you multiply both of the ratios of paint by 2 you get 10 and 18 which makes the same shade if green paint because the ratio is just 2 times more if the original ratio (9:5)
Answer:
5
Step-by-step explanation:
-5 minus -10 = 5
l m a o i used a calculator. Is ur problem even -5 minus -10?
Do you mind if I re-arrange it slightly before we solve it ?
You said 20x + 3.00y ≥ 500
Subtract 20x
from each side: 3.00 y ≥ -20x + 500
Divide each side by 3 : y ≥ -20/3 x + 500/3
Make it an equation,
and graph this line: y = -20/3 x + 500/3
The line is made out of all points where 'y' is EQUAL to
1/3 of (-20x + 500).
The inequality wants to see all the points that are equal to it
AND all the points that are greater than that.
So the graph of the inequality is the line AND every point that's
anywhere above the line. It's called the "half-infinite plane"
bounded by the line.
Answer:
Part a - 25 pieces
Part b - 4 sheets
Step-by-step explanation:
<u>Part a</u>
Think of this in terms of how many "units" can the total paper be cut into. Easiest way to keep track of units is by their area. In other words, take the total area and see how many unit areas fit into it:
Number of units = total area / unit area
N = (85 x 60) / (20 x 10)
N = 5100 / 200
N = 25.5
Therefore the greatest number of pieces the paper can be cut into is 25 units (the 0.5 doesn't count since it's not a full pieces).
<u>Part b</u>
Again, back to units. This time the "total" is 100, and our unit size is 25.5. So:
Number of units = total gifts / gifts per unit
N = 100 / 25.5
N = 3.9
Therefore 4 sheets of wrapping paper will be needed (you need to round the 3.9 up because wrapping paper sheets only come in whole numbers for the purposes of this question).
