4x+17+x+23+80=180. Now combine like terms.
5x+120=180
5x=60
X=12
79 dollars plus its 40% times 4 equals 442.4 that plus 12% equals 495.488 rounded up to 495 dollars and 49 cents
The answer is to what is 5/2 divided by 1/4 is 10
Answer: The length is 15 inches and breadth is 9 inches
Step-by-step explanation:
Given : Area of rectangular sheet = 135 square inches
Perimeter of rectangular sheet = 48 square inches
Now Area of rectangular sheet =
= 135 square inches
perimeter of rectangular sheet =
= 48 square inches
Thus
= 24 square inches
Thus Length = 15 inches
Breadth = 9 inches
To find the time to reach the maximum height you can subtract the constant 6 and write the function as:
h'(t) = -16t^2 + 50t
Then factor it: h'(t) = -2t(8t-25)
Then find the two roots:
t =0 and
8t - 25 = 0 ⇒ t = 25/8 = 3.125
The vertex is in the half between 0 and 3.125, i.e. [0+3.125]/2 = 1.5625
Then the time searched is approximately 1.56 seconds.
