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>
Answer:
D
Step-by-step explanation:
Answer:
The scale factor of all radii of circle Y to all radii of circle Z is 2.5
Step-by-step explanation:
we know that
The radius of circle Y is 4 units
The radius of circle Z is 10 units
To find the scale factor of all radii of circle Y to all radii of circle Z, divide the radius of circle Z by the radius of circle Y
10/4=2.5
Answer:
-2x + 5
Step-by-step explanation:
y-5= -2(x-0)
y= -2x + 5
Answer:
Step-by-step explanation:
sum of ratio=2+9+4=15
1st angle=2/15×180=24°
2nd angle=9/15×180=108°
3rd angle=4/15×180=48°
