1. Divide cost by the pounds so you get the cost of one pound:
1.25 / 2.5= .5
1 pounds of bell peppers costs .50$
2. The beef cost most per pound: 9.56 / 4=2.39
3. He would have paid 11.05 for 8.5 pounds because when you divide 15.30 by 8.5 to get cost per pound and subtract .5 to get .50$ less per pound, then multiply by 8.5 to get the cost for 8.5 pounds, you get 11.05$
Answer:
468.4 meters
Step-by-step explanation:
Find the width of the rectangle.
The area of a rectangle is A=length*width. Substitute the values of length and area and solve for width.
A=length*width
8,400=140*width
60= width
Use the width of the rectangle to find the circumference of the semicircles. Since each semicircle is half of a circle, the perimeter of the two semicircles is equal to the circumference of one circle.
The circumference of a circle is equal to pid, where d is the diameter. The diameter of the semicircle is the same as the width of the rectangle.
So, the diameter is 60 meters. Substitute the diameter into the formula for the circumference and simplify using 3.14 for pi.
≈188.4
(2 times 140)+ 188.4
So, the perimeter of the track is 468.4 meters.
Answer:
x = 12
Step-by-step explanation:
9x + 7 and 115 are alternate exterior angles and are congruent, then
9x + 7 = 115 ( subtract 7 from both sides )
9x = 108 ( divide both sides by 9 )
x = 12
I think it’s D because if you divide 25/20 you get 1.25 and the similar pair would be 15/12.
