Answer: blank=2/3
Step-by-step explanation:
1/2/3+x/2x1/2
solve this then answer
What percentage of its capacity is 9 people?
<em> 12%</em>
What percentage of its capacity is 51 people?
<em> 68 %</em>
What percentage of its capacity is 84 people?
<em>112%</em>
1 ft = 12 inches
6 ft = 72 inches (multiply both sides by 6)
6 ft + 2 inches = 72+2 = 74 inches
6 ft, 2 inches = 74 inches
--------------------
1 ft = 12 inches
2 ft = 24 inches
2 ft + 1 in = 24+1 = 25 inches
2 ft, 1 in = 25 inches
--------------------
1 ft = 12 inches
3 ft = 36 inches
3 ft + 7 in = 36+7 = 43 inches
3 ft, 7 in = 43 inches
--------------------
To rewrite the problem a bit in equivalent form, we have a man who is 74 inches cast a shadow that is 25 inches long. The tree has a shadow of 43 inches. We want to find the height of the tree, which for now we'll call x
(tree height)/(tree shadow) = (person height)/(person shadow)
x/43 = 74/25
25x = 43*74
25x = 3182
x = 3182/25
x = 127.28 inches
The tree is 127.28 inches tall which is the same as 10 ft, 7.28 inches
because 127/12 = 10 remainder 7, then we add on the 0.28 portion
8x + 5 = 3x + 15 |subtract 5 from both sides
8x = 3x + 10 |subtract 3x from both sides
5x = 10 |divide both sides by 5
x = 2
