You can calculate percentages by first finding what 10% of a value is and then what 5 or 1% is. From there you can multiply to find multiples and then add to get the required percentage. The example below shows this.
<span>What is 35% of $40?<span>Step 1<span>What is 10% of $40?10% of $40 = $40 ÷ 10 =<span> $4</span></span><span>10% is a relatively easy percentage and can be found by<span> dividing by 10</span>.</span></span><span>Step 2<span>3 x $4 = $1230% of $40 = $12</span>30% is 3 times ( 3 x) 10% so we multiply what 10% of $40 is by 3</span><span>Step 3<span>What is 5% of $40?5% of $40 = $4 ÷ 2 =<span> $2</span></span><span>5% is half of what 10% is so divide what 10% is by 2 .</span></span><span>Step 4<span>What is 35% of $40?$12 + $2 = $14</span><span>Add what</span></span></span>
The 5 represents 5 thousand
Answer:
60 weeks
Step-by-step explanation:
Factor both numbers 12 and 15:
Find LCM(12,15). The common factor is only 3, multiply ths common factor by all factors that remain. Then
This means that the fewest number of weeks that will pass before both machines are cleaned again in the same week is 60 weeks.
F inverse? then :
let's consider 3x + 9 as y.
so :
y = 3x + 9
y - 9 = 3x
x = y/3 - 3
now replace y with x and you get the inverse.
f^-1 (x) = x/3 - 3
Answer:
(-6, 4)
Step-by-step explanation:
Given the coordinate points (-3,1). If The point (-3,1) is moved 3 places in the negative y direction and 2 places in the positive x direction the required coordinate will be expressed ss;
X' = (-3-3, 1+3)
X = (-6, 4)
Hence the resulting coordinate will be at:(-6, 4)
