Assuming the shape is a piece of a circle, you can determine the ratio of the shape to a full circle. A full circle will have 360 degree but this shape is only 40 degree. Then the ratio would be: 40/360= 1/9 full circle.

Then, using the circle area formula, the area of the 1/9 circle would be: 
full circle area= pi * r^2
full circle area= 22/7 * 6^2
full circle area= 792/7
1/9 full circle area= 792/7*9= 88/7 = 12.57

jane and jill were simplifying the expression (2x2+x) +2(-x2+×) and obtained different answers . who is right and why?​
Romashka [77]

Answer: who ever arrives at the answer x=0/3 =0 is correct

Step-by-step explanation:

Even though I need supporting details from the individual answers of Jane and Jill to pass my own judgment.

Given the expression

(2x²+x) +2(-x²+×)=0

Let's us open the bracket

2x²+x-2x²+2x=0

Collecting like terms

2x²-2x²+x+2x=0

3x=0

x=0/3

x=0

Which of the following statements explains how to solve for w in the equation A = lw?
gladu [14]

Answer:

Divide both sides by l.

Step-by-step explanation:

The equation that we have to solve in this problem is

A=lw

where

A is the area

l is the length

w is the width

Here we want to solve the equation for w, the width. It means that we have to isolate this variable.

In order to do so, we proceed as follows:

1) We divide by l on both sides:

\frac{A}{l}=\frac{lw}{l}

2) We simplify l on the right side, so we get:

\frac{A}{l}=w

So, we have solved for w.

Therefore, the correct answer is

Divide both sides by l.

The function y=60/x relates y, the time in hours that it takes Michael to travel to his grandparents’ house, to x, his average s
Paha777 [63]

Answer:

b) 60 is the distance in miles that must be travelled to get to Michael's grandparents' house

Step-by-step explanation:

hello

at the speed of x mph in 1 hour he travels x miles

so in 60/x hour he travels 60 miles

so 60 is the distance in miles that must be travelled to get to Michael's grandparents' house

another way to see it is as below

distance = vitesse * time so

time = distance / vitesse

hope this helps
