Answer:
$240
Explanation:
12 × 8 = 96 _________ area in square feet
96 × 2.50 = 240 _________ in dollars
Answer:
(x - 4)² + (y + 9)² = 5²
Step-by-step explanation:
The standard form equation is
(x - h)² + (y - k)² = r²
(h, k) is the center
r is the radius
----------------------------
Given (h, k) = (4, -9) and r = 5
(x - 4)² + (y + 9)² = 5²
4 minutes 34 seconds will takes to empty the tank, if the starts completely full and oil drained at a rate of 2.5 per minute.
Step-by-step explanation:
The given is,
Tank is shaped like a cylinder that is 3 ft long with a diameter of 2.2 ft.
Oil drained at a rate of 2.5 per minute.
Step:1
Time taken to dry the oil tank is,
T = ....................................(1)
Step:2
Volume of the oil is,
.................................................(2)
Where, r - Radius of Cylinder
r = 1.1 ft
From eqn (1),
V = × × 3
= 11.40398
Step:3
From equation (1)
=
= 4.56
= 4.56 minutes
T = 4 minutes 34 seconds
Result:
Time taken to dry the oil tank is 4 minutes 34 seconds, if a cylinder is 3 ft long with a diameter of 2.2 ft and oil is drained at a rate of 2.5ft^3 per minute.
8(w-2)=2w+44
We move all terms to the left:
8(w-2)-(2w+44)=0
We multiply parentheses
8w-(2w+44)-16=0
We get rid of parentheses
8w-2w-44-16=0
We add all the numbers together, and all the variables
6w-60=0
We move all terms containing w to the left, all other terms to the right
6w=60
w=60/6
w=10
