13 because the scale factor is 1/3
Answer:
£135
Step-by-step explanation:
Original price = 100%
Percentage increase = 20%
New price = 100% + 20% = 120%
If 120% = £162
What about 100% = ?
= (100 x 162) ÷ 120
= 16200 ÷ 120
= £135
Step-by-step explanation:
Use ToA method (tan = opposite / adjacent)
For this question we have to use pythagoras' Theorem to find the adjacent side.
take a as the length of the adjacent side.
given b = 12
c = 13
By pythagoras' Theorem,
Now we can find tan(x)
tan(x) = Opposite / adjacent
60 is thaks for points
Step-by-step explanation:
I think
Answer: y = (-1/2)x + 1 which is the same as y = -0.5x + 1
We'll use y = mx+b with m as the slope and b as the y intercept
The slope is m = -1/2 = -0.5 because we go down 1 each time we move to the right 2 units. We have rise = -1, run = 2, so slope = rise/run = -1/2 = -0.5.
The y intercept is where the line crosses the y axis, so b = 1
Use m = -1/2 and b = 1 to go from y = mx+b to y = (-1/2)x+1
