Answer:
c = 1
Step-by-step explanation:
"10 is 8% of a": 0.08a = 10, or <u>a = (10/0.08)</u>
"5 is 4% of b": 0.04b = 5, or <u>b = (5/0.04)</u>
"c equals b/a": c = (b/a)
----
What is the value of c?
c = (b/a)
c = ((5/0.04)/(10/0.08))
c = (5/0.04)*(0.08/10)
c = (5/10)*(0.08/0.04)
c = (1/2)*(2)
<u>c = 1</u>
Answer:
b
Step-by-step explanation:
3 1/2 x 3 x 1/2= 5.25 or 5 and 1/4

Dilation makes things bigger
Answer:
Half an inch
Step-by-step explanation:
Perimeter of the frame = 28 inches
Length fo the frame = 7 + x + x = (7 + 2x) inches
Width of the frame = 5 + x + x = (5 + 2x) inches
Perimeter of a rectangle is given as: 2(length) + 2(width)
Therefore:
28 = 2(7 + 2x) + 2(5 + 2x)
Solve for x
28 = 2*7 + 2*2x + 2*5 + 2*2x
28 = 14 + 4x + 10 + 4x
Collect like terms
28 = 14 + 10 + 4x + 4x
28 = 24 + 8x
Subtract 24 from both sides
28 - 24 = 24 + 8x - 24
4 = 8x
Divide both sides by 8
4/8 = 8x/8
½ = x
Width of the frame = x = ½ of an inch
