Answer:
The percentage of error in the question is 75%.
Step-by-step explanation:
To find the percentage of error, we need to subtract the actual value from the value that was expected, divide the result by the expected value.
He predicted that the crop would produce 8 bushels so this is our expected value. The actual value, which is the number of bushels produced, is 14.
- If we make the calculation (14 - 8) / 8 = 6 / 8.
- And then multiply the result by 100 to find the percentage, (6 / 8) x 100 = 75.
So the percentage of error in the question is 75%.
I hope this answer helps.
Answer:
30 inkjet printers
30 laser printers
Step-by-step explanation:
Let x be inkjet printer
Let y be the laser printer
Total printer produced per day = 60
This implies that x+y = 60
The company has 120 labor hours per day. If it has 1 labor hour to make a inkjet printer and 3 labor hours to make a laser printer, we will have
x + 3y = 120
So we have
x + y = 60 ........(1)
x + 3y = 120 ........(2)
Subtract equation 1 from 2
We have
2y = 60
y = 60/2
y = 30
Put y= 30 into equation 1
x + y = 60
x + 30 = 60
x = 60 -30
x = 30
Therefore we have 30 inkjet printers and 30 laser printer.
Answer : $757
explanation: 57.75 + 9.50 = 67.25
67.25/757
Answer:
14
Step-by-step explanation:
To find the perimeter, you need to add the lengths of each side.
In order to find the length of each side, imagine each side of the given triangle is the hypotenuse of an imaginary triage and use the Pythagorean Theorem (a² + b² = c²).
For the top side, I see an imaginary triangle with one side of 3 and the other side of 1. This means the length of the top of the given triange is √10:
3² + 1² = c²
9 + 1 = c²
10 = c²
√10 = c
For the left side, my imaginary triangle has one side of 5 and the other is 1. The length of this side is √26:
5² + 1² = c²
25 + 1 = c²
26 = c²
√26 = c
For the right side, I see a triange with two sides of 4 and the hypotenuse is √32.
This means the triangle in our question has side of √10, √26, and √32
If I add all of these up on a calculator, I get 13.918 which rounds up to 14 because the question wants the nearest whole unit.
