Answer: C.) $51
Step-by-step explanation:
$85.00 x 40%
85.00 x 0.40= 34
85.00-34=51.00
$51
Answer:
48
Step-by-step explanation:
0.8 times 60= 48
Answer:
120 units²
Step-by-step explanation:
Perimeter = PS + SQ + PQ
50 = SQ + SQ + (SQ -1)
51 = 3SQ
17 = SQ
17 -1 = 16 = PQ
The midpoint of the base is one leg of the right triangle whose other leg is the height of this isosceles triangle. That height is ...
h = √(17² -(16/2)²) = √225 = 15
Then the area is ...
A = (1/2)bh = (1/2)(16)(15) = 120 . . . . . square units
Perimeter of a square=4*side length
160=4*side length
40=side length
Therefore, 39.99999 (repeating 9s) is the maximum side length in feet for the perimeter to be less than 160. If it was 40 feet as the side length, then it would not be less than 160.
Hope this helps!
we can use formula
now, we can find a and b
Initially , price is 500
so,
At 
now, we can plug back
At 
we can use it and find b
now, we can solve for b
and we get
so,
