Answer:
Step-by-step explanation:
did you get the answers???
X = large boxes and y = small boxes
x + y = 70.....x = 70 - y
60x + 65y = 4300
60(70 - y) + 65y = 4300
4200 - 60y + 65y = 4300
5y = 4300 - 4200
5y = 100
y = 100/5
y = 20 <=== the small boxes weigh 20 lbs
x + y = 70
x + 20 = 70
x = 70 - 20
x = 50 <== and the large boxes weigh 50 lbs
Answer:
314.16 sq mm
Step-by-step explanation:
formula for area of a circle = pi(r^2)
if the diameter is 20mm then the radius is 10 mm
When you plug in pi(10mm^2) you get 314.16 sq mm
Greater
If we get common denominators
1/2=15/30
3/15=6/30
15>6 therefore 1/2>3/15
