Logan measured a line to be 7.4 inches long. If the actual length of the line is 7.7 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?
PWEEESE HELP FOR BRAINLIEST PLEASEEEEEE
Answer:
4.0541
Step-by-step explanation:
I don't know if this is correct but this is what I got.
You would take the error and divide it by the theoretical value and then multiply that by 100.
7.7 - 7.4 = 0.3
0.3 ÷ 7.4 = 0.04054054
0.04054054 x 100 = 4.05405405 (simplify) = 4.0541%

Matthew has lived in NY for 10 years. Matthew earns $17.25 per
hour. He worked 5.8 hours on Friday, 4.5 hours on Saturday, and 8
hours on Sunday. How much money did Matthew earn in all on Friday,
Saturday, and Sunday?
Answer:18.3
Step-by-step explanation: 18.3 because 5.8 + 4.5 =10.3 then add 8 its 18.3
Answer:
$315.68
Step-by-step explanation:
We would first add up all of the hours, so that would be 5.8+4.5+8 to get 18.3 hours. Since it is saying $17.25 per hour we would multiply 17.25 and 18.3 to get 315.675. But, because we are dealing with money, our answer would be rounded to the nearest hundredth. So, Mathew earned $315.68 on Friday, Saturday, and Sunday altogether.

Answer:
A secant line contains a chord always
Step-by-step explanation:
A line intersecting in two points is called a secant line, in one point a tangent line and in no points an exterior line. A chord of a circle is the line segment that joins two distinct points of the circle. A chord is therefore contained in a unique secant line and each secant line determines a unique chord.

2y - 15 + 15 = 25 + 15
2y = 40
2y ÷ 2 = 40 ÷ 2
y = 20

g÷ 5/8 =1
basically its asking what divided by 5/8 = 1
Answer:
5/8 divided by 5/8 = 1
Step-by-step explanation:
First, you know that dividing by a fraction is the same as multiplying by its reciprocal, so dividing by 5/8 is the same as multiplying by 8/5.
[tex]g / 5/8 = 1\\g * 8/5 = 1[/tex]
Now, multiply both sides by 5 to get rid of the fraction.
[tex]8g = 5[/tex]
divide both sides by 8
[tex]g = 5/8[/tex]

Find the rate of change from 2012 to 2016
A. -10.5 students per year
B. 10.5 students per year
C. -11.25 students per year
D. 11.25 students per year
Answer:
D. 11.25 students per year
Step-by-step explanation:
rate of change
[tex] = \frac{400 - 355}{2016 - 2012} [/tex]
[tex] = \frac{45}{4} [/tex]
=11.25
The rate of change from 2012 to 2016 is 11.25 students per year.
Therefore, the correct answer is D.
Given that a graph is showing the number of students in a class.
We need to find the rate of change from 2012 to 2016.
Also, from the graph we can see the number of students in 2012 and 2016 was 355 and 400 respectively.
To find the rate of change from 2012 to 2016, we can use the formula:
Rate of change = (Final value - Initial value) / Time interval
In this case, the initial value is the number of students in 2012, which is 355, and the final value is the number of students in 2016, which is 400.
The time interval is 4 years (from 2012 to 2016).
Plugging these values into the formula, we get:
Rate of change = (400 - 355) / 4
= 45 / 4
= 11.25
Therefore, 11.25 students have changed between 2012 and 2016 with this rate of change.
