Answer:
3 and 4
Step-by-step explanation:
3) 1=-(-1)
1=1
0=0
4) 0=0
when both sides are equal means it is true.
Answer:
3/7 = 6/14
5/11 = 10/22
Step-by-step explanation:
3/7 < 5/11
Answer:
Perimeter = 90
Step-by-step explanation:
Let c = hypotenuse, 15 = b, and a = other leg
Given: c/a = 13/12, so a = 12c/13.
c^2 = b^2+a^2
Using Pythagorean Theorem: c^2 = 225 + 144c^2/169.
169c^2 = 169(225) + 144c^2
25c^2 = 169(225)
5c = 13(15)
c = 13(3) = 39.
and a = 12*39/13 = 12*3 = 36
You now can compute all three sides, and
thus obtain perimeter = 36+39+15 = 90.
There would be 65 doses in a 13 ounce bottle.
