Answer:
12.56x^2+452.16
Step-by-step explanation:
A=pie r^2
(4x-24)/2= 2x-12 which is your radius
(2x-12)^2=4x^2+144
Pie=3.14ish
3.14(4x^2+144)
12.56x^2+452.16
Answer:
25
Step-by-step explanation:
6(x-5) = 4x+20
6x-30=4x-20
6x25=150-30=120
4x25=100+20=120
Answer: Holding a tray
Step-by-step explanation:
The lateral surface area consists of 2 sides with 11 unit long and 4 unit high, and 2 sides with 8 unit long and 4 unit high. Each side is a rectangle. So basically you use area of rectangle to determine the lateral surface area
lat sa = 2 × area of rectangle + 2 × area of rectangle
In this case, it will be
lat sa = (2 × l × h) + (2 × w × h)
lat sa = (2 × 11 × 4) + (2 × 8 × 4)
lat sa = 88 + 64
lat sa = 152
The lateral surface area is 152 squares unit
Answer:
Step-by-step explanation:
She makes $325 a week, so go to the 8th row, for weekly income of $300 to $400. She claims 2 exemptions, so go to the third column labeled 2. The value is 2. That means the $2 is withheld from her paycheck on top of the 6.25% for FICA. The total is therefore:
$2 + (0.0625) ($325)
$22.3125
Rounded to the nearest cent, that's $22.31.
