Answer:
The length of the leg is 13.416
Step-by-step explanation:
To calculate one side of a right triangle from the other 2 sides we have to use Pythagoras
h = hypotenuse = 18
a = leg 1 = 12
b = leg 2 =
h² = a² + b²
we replace the known values and solve
18² = (12)² + (a)²
324 = 144 + (a)²
324 - 144 = (a)²
324 - 144 = (a)²
√180 = a
13.416 = a
The length of the leg is 13.416
Answer:
20 inches of ribbon.
Step-by-step explanation:
i did 80÷4=20
so every one bows need 20 inches of ribbon.
Let x be the number of dime then the number of quarter will be 35-x
1 dime = 10 c & 1 quarter = 25 c, so
(x*10)+(35-x)(.25) = 575
-15x = -300
15x = 300 & x = 20 (dime) & Quarter = 15
