Answer:
16
Step-by-step explanation:
(2 means squared) (c is the hypotenuse)
a2+b2=c2
a2+ (12×12) = (20×20)
a2+144=400
a2=256
a=16
Answer:
The dimensions of the piece of metal can be represented by x and x+10.
Now, 2 in squares are being cut out of each corner.
So the new dimensions are x-4 (2in from each side) and x+10-4 or x+6.
When you fold it up, the height becomes 2 and the base has dimensions x-4 and x+6. Now plug this into the volume formula.
V=l*w*h
1302 = (x+6)(x-4)(2)
651 = x2+2x-24
0 = x2 + 2x-675
0 = (x+27)(x-25)
x=-27 reject since lengths cannot be negative or x=25.
So your original dimension for the piece of metal are 25 by 35.

Answer:
7/12
Step-by-step explanation:
Divide both the numerator & denoniminator by 7.
49 / 7 = 7
84 / 7 = 12
7/12
1 yr = 12 months
- 2931/12 = - 244.25 per month
Answer:
v < 2
Step-by-step explanation:
1+4v<9
Subtract 1 from each side
1-1+4v<9-1
4v < 8
Divide each side by 4
4v/4 <8/4
v < 2
