Answer:
V ≈ 2011 cm³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = area of base × perpendicular height
V = πr²h ( r is the radius and h the height )
Here r = 8 and h = 10, thus
V = π × 8² × 10
= π × 64 × 10 = 640π ≈ 2011 cm³ ( to nearest whole number )
Answer:
40
Step-by-step explanation:
Let the number be y
-1/2 × y = -20
y = -20 ÷ -1/2
y = 20 × 2
y = 40
Answer:
4x+50y+11
hope this helps :) plz brainliest

Answer:
Multiply it by 100%
Step-by-step explanation:
1/2 = 1/2×100% = (1/2×100)% = 50% . . . . . for example
_____
Equivalently, express the ratio with 100 as the denominator.
... 1/2 × 50/50 = 50/100 = 50%
_____
It can be useful to think of "%" as a shorthand way to write "/100".
Answer: y = 20x+75
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
The cost (y) must be equal to the product of the cost per hour of installation (20) and the number of hours that it takes (x); plus the fixed cost of parts and installation (75).
Mathematically speaking:
y = 20x+75
