A scientist estimated that a mixture would need 3 milliliters of a chemical to balance. The actual amount needed was 7 milliliters. What was the percent error of the scientist's estimation?A. 133.33%
B. 3%
C. 42.86%
D. 57.14%

Answers

Answer 1
Answer:

Answer:

57.14%

Step-by-step explanation:

Error(E)is defined as the percentage difference an estimate(e) amount is from the actual(a) amount. The actual amount need was 7 mililters and the estimate was 3 mililiters.

Error is defined as:

E=(a-e/a)*100

E=(7-3/7)*100=57.14

The percet error if the scientists estimation is 57.14%

Find the shaded region. Round to the nearest tenth.

Answers

That's a circle less what's called a segment, the white part of the circle.

The circle has area A = πr² = π(8.35)²

The circular sector formed by the 100° angle is a fraction of A so has area

S = (100/360) A

The isosceles triangle in the sector has two sides that are radii and an included 100° angle so area

T = (1/2) ab sin θ = (1/2) (8.35)(8.35) sin 100°

The circular segment has area S-T so the area of the pink region is

P = A - (S-T) = A+T-S = π(8.35)² + (1/2) (8.35)² sin 100° - (100/360) π(8.35)²

= (8.35)²(π -(100/360)π + (1/2) sin 100°)

= (8.35)²((260/360)π + (1/2) sin 100°)

I hate ruining a nice exact answer with an approximation, but they asked.

What is the area of a parallegram that has a base of 12 3/4 in and a height of 1/2 in

Answers

So the parallelogram Formula is B×H
Plug in 
12 3\4 ×1\2
51\4 × 1\2 
51\8 = 6.375
So if you solve you will be gated 6.375 
area=base times height
base=12 and 3/4
height=1/2
area=12 and 3/4 times 1/2
12 and 3/4=12+3/4
area=(12+3/4) times 1/2
distribute using distributive propery a(b+c)=ab+ac
area=12 times 1/2+3/4 times 1/2
area=6+3/8
area=6 and 3/8 square inches (square inches=in^2))
