the question is not so clear
is it (x+3)/3 or what you have written is correct
Step-by-step explanation:
Figure the fraction of box tops each class collected, then multiply the prize money by that fraction.
Total box tops = 3760 +2301 +1855 = 7916
Mr Coronado's class's fraction: 3760/7916 × $600 = $284.99
Mrs De Souza's class's fraction: 2301/7916 × $600 = $174.41
Mr Nost's class's fraction: 1855/7916 × $600 = $140.60
Answer:
6,280 ft³
Step-by-step explanation:
To find lateral surface area, use the formula L = 2
rh, then plug in the values:
L = 2(3.14)(25)(80)
L = 12,560 ft³
Since its a half cylinder, we have to divide this by 2:
12,560/2 = 6,280
So, the lateral area of the roof is 6,280 ft³
Answer:
7.
lateral surface area of traingular prism=perimeter of traingle ×length=[5+3+4]×6=72cm²
curved surface area=2[area oftraingle]=2×1/2×4×3
=12cm²
now
total surface area=72cm²+12cm²=84cm²
8.
volume of traingular prism=area of traingle ×length
=1/2×12×3.4×4=81.6cm³
