Answer: 2.833
Step-by-step explanation:
Add up the amount of light bulbs: (7+6+4).
Divide 17 (^the sum^) by 6 (the amount of 75 watt bulbs).
Answer:
m= 4
b= -12
( 4, -12)
Step-by-step explanation:
m= y2- y1/ x2-x1
m= 12 - 4/ 4 - 2
m= 8/ 2
m= 4
y= 4x + b
(2,4)
4= 4(4) + b
4= 16 + b
-16+4= b
-12= b
b= -12

Volume of a Cylinder: V = πr²h
- V is volume
- r is radius
- h is height
Step-by-step explanation:
<u>Step 1: Identify</u>
Radius <em>r</em> = 12 ft
Height <em>h</em> = 19 ft
<u>Step 2: Find Volume</u>
- Substitute in variables [Volume of Cylinder]: V = π(12 ft)²(19 ft)
- Evaluate exponents: V = π(144 ft²)(19 ft)
- Multiply: V = 2736π ft³
- Substitute π: V = 2736(3.14) ft³
- Multiply: V = 8591.04 ft³
Answer:
<u>x = 1.07</u>
Step-by-step explanation:
13 ( 6x - 9) = -33
78x - 117 = -33 ( opening brackets and multiplying )
78x = 84 ( - 117 taken to the other side makes it positive)
x = 84 / 78
x = <u>1.07</u>
