Answer:
12
Step-by-step explanation:
Since a circle is 360 degrees all you do is 360/30 since that's the angle of your original "piece" which would get you 12 pieces
1. We assume, that the number 320 is 100% - because it's the output value of the task.
<span>2. We assume, that x is the value we are looking for. </span>
<span>3. If 320 is 100%, so we can write it down as 320=100%. </span>
<span>4. We know, that x is 45% of the output value, so we can write it down as x=45%. </span>
5. Now we have two simple equations:
1) 320=100%
2) x=45%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
320/x=100%/45%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 45% of 320
320/x=100/45
<span>(320/x)*x=(100/45)*x - </span>we multiply both sides of the equation by x
<span>320=2.22222222222*x - </span>we divide both sides of the equation by (2.22222222222) to get x
<span>320/2.22222222222=x </span>
<span>144=x </span>
x=144
<span>now we have: </span>
<span>45% of 320=144</span>
Answer:
this means it shows half as a fraction turned into a decimal
Step-by-step explanation:
1/2=fraction form
0.5=decimal form
50%=percent form
half=word form
The rule for rounding is that if the fraction is less than 1/2, we round down; and if the fraction is more than 1/2, we round up.
Because 5/6 is a greater fraction than 1/2, we must round the existing whole number (8), up.
8 5/6 rounded to the nearest whole number is 9.
2y+2=18 Subtract 2
2y = 16 Divide by 2
y = 8 Answer is y = 8
