Answer: 2.2235%
Step-by-step explanation:
The formula for percentage error os written as:
(Approximate value)/Exact value × 100
Here,
Approximate value = 8.50g/mL
Exact value = 8.69g/mL
Slotting the values into the formula will be:
= (Approximate value)/Exact value × 100
= (8.69 - 8.50)/8.50 × 100
= 0.19/8.50 × 100
= 0.0223529 × 100
= 2.2235%
Muitply by two on both sides then subtract then divide to find x
What u can do is turn the 10% into a decimal like .10 and then multiply it by 83 and then you would get 8.3 . I hope this was helpful
Answer:
C≈9.42m
Using any of this formulas
C=2πr
C=2πrd=2r
Solution:
C=πd=π·3≈9.42478m
<u>Answer:</u>
(x,y)→(y,x); A' is at (2, −7)
<u>Step-by-step explanation:</u>
According to the given image, the coordinates of the kite ABCD are:
A (-7, 2)
B(-5, 3)
C(-2, 2)
D(-5, 1)
Kite ABCD is then reflected over the line y = x, the main rule to find the coordinates of the images is (y, x).
So for point A (-7, 2), the coordinates of the point A' after reflecting over the line y=x will be A' (2, -7).
