Answer:
The area of he field that is not reached by the sprinkler = 168.56
Step-by-step explanation:
Side of the square field (a) = 28 m
Diameter of circular area (D) = 28 m
Radius of circular area (r)= 14 m
Area made by square field
= 784
Area made by circular field
= 615.44
Field is not reached by the sprinkler A' =
Put the values of &
A' = 784 - 615.44
A' = 168.56
Therefore the area of he field that is not reached by the sprinkler = 168.56
Squares, rectangles, and parallelograms.
Answer:
She needs to sell for 64 more hours
Step-by-step explanation:
Yes, so the Y intercept of the linear regression line is 250 ( it is on the y-axis at point [0,250]. You can also see that for every 2x the number on the y axis decreases by 50. This means that the slope is -25. Now put what we know into the equation for a line - y=mx+b
y = -25x +250
Answer:
Two buses leave towns 760 mi apart at the same time and travel toward each other. One bus travels
18 mi/h slower than the other. If they meet in
5 hours, what is the rate of each bus?
~~~~~~~~~~~~~~~~
Let x be the rate of the slower bus, in miles per hour.
Then the rate of the faster bus is (x+18) mph, according to the condition.
The slower bus covered 5x miles before the buses meet each other.
The faster bus covered 5*(x+18) miles before they meet each other.
The sum of distances covered by buses is 3x + 5*(x+18).
It is equal exactly 760 miles. It gives you an equation
5x + 5(x+18) = 760.
Simplify and solve for x:
5x + 5x + 90 = 760,
10x = 760 - 90,
10x = 670 ====> x = 670%2F10 = 67.
Thus you found the rate of the slower bus. It is 67 miles per hour.
Then the rate of the faster bus is 67 + 18 = 85 mph.
Solved.
