Answer:
Step-by-step explanation:
Answer:
a= 73.2
b =36.6
c = 76.2
Step-by-step explanation:
Perimeter of the triangle is the distance round the triangle.
Let the 3 sides be a, b and c
Side a of the triangle is twice as long as side b. This means
a = 2b
Side c is 3 feet longer than side a. This means
c = a + 3
The perimeter of the triangle is 93 feets. Formula for finding the perimeter of the triangle is
(a + b + c)/2
Therefore,
93 = (2b + b + 2b + 3)/2
93 = (5b + 3)/2
5b + 3 = 93 × 2 = 186
5b = 186 - 3 = 183
b = 183/5 = 36.6
a = 2b = 2 × 36.6 = 73.2
c = a + 3 = 73.2 +3 = 76.2
The answer is this
42%, 17/40, 0.43
First, find the total amount of box tops:
3760 + 2301 + 1855 = 7916
Next find the percent that Mr Aceves class contributed:
3760/7916 = about .47 or 47 percent.
The percent Mrs Bacas class contributed:
2301/7916 = about .29 or 29 percent
The percent Mr Canyons class contributed:
1855/7916 = about .23 or 23 percent.
After, find 47 percent of $600, because Mr Aceves class contributed 47 percent of the total box tops.
.47 * 600 = $282
Next find 29 percent of $600, because Mrs Bacas class contributed 29 percent of the total box tops.
.29 * 600 = $174
Lastly find 23 percent of $600, because Mr Canyons class contributed 23 percent of the total box tops.
.23* 600 = $138
