So because trail Y has a negative slope, and X is perpendicular to Y the X has a positive slope. \ <---- neg slope y and / <----- pos slope x
Answer:
± 15 cm
Step-by-step explanation:
In the first case, since the measurement is 1 cm too long or too short, the error is ± 1 cm.
In the second case, the uncertainty or error is also ± 1 cm.
Now, since there are 15 cars, and there is an error of ± 1 cm in each measurement, by the error formula the total error in the sum of both cases is 15 × ±1 cm = ± 15 cm
So, the total error in both cases is ± 15 cm.
Answer:
15%
Step-by-step explanation:
profit=sp -cp
cp=sp-profit
=17250-2250
=15000
profit%= profit amount/cp *100%
=2250/15000×100
= 15
C.
If you properly distribute C it will give you the above equation.
1/4 * -x = -1/4x
AND
1/4 * 2 = 1/2
To get the area of the half circle, do π r².
Let's use 3.14 as pi.
First square 2 to get 4 then multiply it by 3.14 to get 12.56. Since this is a half circle we have to divide it by 2 for the area: 6.28.
Then for the triangle multiply 6 times 2 (12) then divide it by 2 to get 6. Then add the two together to get 12.28 then round to the nearest tenth to get a final answer of 12.3 m². Hope this helps!
