Answer:
He will charge $28.
Step-by-step explanation:
We know that Jamal charges $3.50 per square yard.
Now we need to find the area in the image, it may be kinda hard to see it, but we can think of the image as a rectangle of 4yd by 3yd where we subtracted the area of a square of side length equal to 2yd.
The area of the rectangle is:
A = 4yd*3yd = 12 yd^2
And the area of the square is:
a = (2yd)^2 = 4 yd^2
The area of our image (equal to the difference between the area of the rectangle and the area of the square) is:
Area = A - a = 12 yd^2 - 4 yd^2 = 8 yd^2
Area = 8 yd^2
And he charges $3.50 per square yard, then for 8 square yards he charges 8 times that amount, which is:
C = 8*$3.50 = $28
Answer:
y = -2x+5
Step-by-step explanation:
2x+y=5
Subtract 2x from each side
2x-2x +y=-2x+5
y = -2x+5
So to start you should get x and y on the same side and get the numbers on one side. Then you should cancel out a variable. Because both y’s are 1 and they are opposite charges they will both cancel out to 0. Then add what is remaining which is the 2x and the 3x and equal that to +9-4 which equals 5. You want x to be all by itself so you would divide both sides by 5 and get that x=1. Then you would just substitue and solve for y. Hope this helped!
There are several information's already given in the question. Based on the information's provided, the answer can be easily deduced.
Distance covered by the hang glider = 303 miles
Time taken by the hang glider for covering the distance = 8 1/2 hour
= 17/2 hours
Then
Average rate of flight = Distance/ Time
= 303/(17/2) miles per hour
= (303 * 2)/17 miles/hour
= 606/17 miles/hour
= 35.65 miles/hour
I hope the procedure is clear enough for you to understand.<span />
