<span>When you calculate results that are aiming for known values,
the </span>percent error<span> formula
is useful tool for determining the precision of your calculations. The formula
is given by: The experimental value is your calculated value, and the
theoretical value is your known value.</span>
% error = | ( experimental – theoretical) / theoretical | *
100
% error = | (44 – 45.5) /45.5| * 100
<span>% error = 3.30 %</span>
Answer:
To be a function, each input must only have one output. In this case, input 4 has two outputs, so (4 , -2) can be removed for it to be a function.

Answer:
there were a total of 55 people at the party.
Step-by-step explanation:
In order to create the equation representing this scenario we first need to represent each step in a formula. Since the total number of people is represented by x we can multiply 3/5 by x and subtract 9 from that. This would then be equal to 24 like so...
3/5x - 9 = 24
Now that we have the formula we can perform opposite operations to isolate x and solve for it.
3/5x - 9 = 24 ... add 9 on both sides
3/5x = 33 ... divide both sides by 3/5
x = 55
Finally, we can see that there were a total of 55 people at the party.
1/162
2*3=6
6*3=18
18*3=54
54*3=162
Split the figure into sections to find the area. The rectangle area is 70cm^2. The triangle area is 5•3.5, or 17.5cm^2. Add them together.
The total area of the figure is 87.5cm^2
