Formula
---------------------------------------------------
Volume of the paint = πr²h
---------------------------------------------------
Find Volume of the paint in the bucket
---------------------------------------------------
Volume of the paint = 3.14 x 3.5² x 8 = 307.72 in³
---------------------------------------------------
Find the cost of the paint
---------------------------------------------------
1 in³ = $0.05
307.88 in³ = $0.05 x 307.72
307.88 in³ = $15.39 (nearest hundredth)
---------------------------------------------------
Answer: The paint cost $15.39
---------------------------------------------------
Answer: 85
Step-by-step explanation:
To solve this problem, we want to use the order of operations, or PEMDAS.
Parenthesis
Exponent
Multiply
Divide
Add
Subtract
To be more specific, you evaluate the expression in the order from top to bottom. To clarify, it is multiply OR divide, depending on which comes first, left to right. This also applies to add OR subtract.
------------------------------------------------------------------------------------------------------------
20÷(5-3)+5²(3) [solve parenthesis]
20÷(2)+5²(3) [solve exponent]
20÷2+25(3) [solve multiply or divide, left to right]
10+75 [solve add or subtract]
85
700,000
Look at the ten thousands place. There is a 7, which is greater than five, so that means you have to round the number 6 up to a seven
6a³-18a²-1620a
Collect 6a:
6a(a²-3a-270)
6a(a-18)(a+15)
