In this question, we're trying to find the cost of feeding the cats for a year.
We know that we use 12 cans to feed the cats
We also know that each can costs $0.60
To find how much the cafeteria spent on the cats, we need to see how much 12 cans cost, and multiply that by 52 to get our yearly cost
Solve:
12 · 0.60 = 7.2
12 cans = $7.20
Now multiply 7.20 by 52 to get our minimum yearly cost for the cats.
52 · 7.20 = 374.4
This means that it costs $374.4 to feed the cats for a year.
Answer
$374.40
Answer:
The three angles of the right-angled triangle are
a = 35°
b = 90°
c = 55°
Step-by-step explanation:
We are given the ratio of angles of a right-angled triangle
a:b:c = 7:18:11
Recall that the sum of interior angles in a right-angled triangle is always 180°
7x + 18x + 11x = 180
36x = 180
x = 180/36
x = 5
a:b:c = 7x:18x:11x
a:b:c = 7(5):18(5):11(5)
a:b:c = 35:90:55
a = 35°
b = 90°
c = 55°
Alternatively:
We are given that the smallest angle is 35°
a = 7x = 35
x = 35/7
x = 5
b = 18x
b = 18(5)
b = 90°
c = 11x
c = 11(5)
c = 55°
