Therefore,
Answer:
2/3
Step-by-step explanation:
To find the slope solve the equation in the form of y=mx+b.
4x-6y=18
-6y= -4x+18
y= 2/3x-3
The slope is 2/3.
Answer:
≈ 39.3 in²
Step-by-step explanation:
The area of the sector is calculated as
A = area of circle × fraction of circle
= πr² × 
= π × 10² × 
= 
≈ 39.3 in² ( to 1 dec. place )
Answer:
b) 70.6
Step-by-step explanation:
To calculate average you need to add up all the numbers and divide by the quantity of numbers. They are calculating with mph, with ten hours, so there will be ten numbers. First you do 73 x 6 (6 because of 6 hours of 73 mph) which is 438. Then you do 67 x 4 which is 268. you add it up, then find a total of 706. Then you divide it by ten to find the answer 70.6
