T=d/r
plug in your numbers and divide then you have your answer.
The triangles are said to be similar, so the measures of sides in the larger triangle are proportional to the measures of sides in the smaller triangle. The measures of the two long sides have the ratio 182:65, so we expect the ratio of the shortest sides to be the same:
... ? : 45 = 182 : 65 . . . or . . . ?/45 = 182/65
Multiplying the equation by 45 gives us
... ? = 45·(182/65) = 126
The appropriate choice is ...
... C. 126
15 people
8 older than 30
9 have facial hair
over 30 and facial hair= 5/15
5/15= 33.3%
3 launchers + shipping = $50
shipping = $5
so to find the price of just the launchers we do $50-$5=$45
so 3 ballons = $45
divide be 3 to find the price of one launcher $50 / 3 = $15
The total cost she needs is 11000 times 5 which is 55,000. so you do 5 times 5000 for her annual grant is 25000 and 900 times 5 is 4500. now you add 25000 plus 4500 is 29500. 29500 is what she has. 55,000 minus 29500 is 25,500. 25,500 is what she needs now. now she has a loan of 400 per year. 400 times 5 is 2,000. 25,000 minus 2,000 is 23,000. so the answer is that she needs to borrow 23,0000.
