The students measured length during a science experiment,they got 12 cm.But the actual measurement was 14.25cm.what was the percent error?
Answers
Answer:
Percent error = 15.79%
Step-by-step explanation:
Given the following data;
Experimental value = 12cm
Actual value = 14.25cm
To find the percentage error;
Percent error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, it is given by this expression;
[tex] Percent \; error = \frac {experimental \;value - actual \; value}{ actual \;value} *100[/tex]
Substituting into the equation, we have;
[tex] Percent \; error = \frac {12 - 14.25}{14.25} *100[/tex]
[tex] Percent \; error = \frac {2.25}{14.25} *100[/tex]
[tex] Percent \; error = 0.1579 *100[/tex]
Percent error = 15.79%
Holly shipped a 5-pound package for $4. She shipped a 3-pound package for $3.60 and a l-pound l package for $3.20. A 10-pound package cost $5 to ship. The cost follows a pattern based on the
weight. Which expression could be used
to find the shipping cost for a package
of p pounds?
Answers
Answer:
the answer would be A
Step-by-step explanation:
The cost seems to start at 3 and increase by each pound times .20 cents. Ex: 1 x .20 =.20 + 3 =3.20
find the equation of a straight line passing through the point (1,2) and making an intercept of 3 on the positive y-axis.
Answers
Question: equation of the line.
Solution:
General equation of a line: y = kx+d,
whereby:
the point (y|x) lies on the line
When x = 0, y = d
The point (0|3) says that d = 3.
So far, the equation is y = kx +3 ……… (1)
Inserting the point (1|2) into (1):
2 = k(1) + 3 => 2–3=k => -1 = k
Putting k into (1):
y = -1x + 3 => y = -x + 3 => y = 3 - x
Answer:
y = 3 - x

A construction worker drops a hammer while building the Grand Canyon skywalk 4,000ft above the Colorado River. Use the formula t=h‾√4 to find how many seconds it takes for the hammer to reach the river. Round your answer to the nearest tenth of a second.
Answers
Answer:
The hammer reaches the river after 15.8 seconds.
Step-by-step explanation:
The formula to find for how long it takes for the hammer to reach the ground is given by:
[tex]t = \frac{\sqrt{h}}{4}[/tex]
In which h is the initial height.
A construction worker drops a hammer while building the Grand Canyon skywalk 4,000ft above the Colorado River.
This means that [tex]h = 4000[/tex].
So
[tex]t = \frac{\sqrt{4000}}{4}[/tex]
[tex]t^2 = \frac{4000}{16}[/tex]
[tex]t^2 = 250[/tex]
[tex]t = \sqrt{250}[/tex]
[tex]t = 15.8[/tex]
The hammer reaches the river after 15.8 seconds.

[tex]-\frac{3}{2}[/tex] < x or x > 4
Step-by-step explanation:
Convert the inequality to an equation.
2x² - 5x = 12
2x² - 5x - 12 = 0
Factor by grouping.
(2x + 3)(x - 4) = 0
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
2x + 3 = 0
x - 4 = 0
Solve for x.
x = -3/2
x = 4
Use each root to create test intervals.
The solution consists of all of the true intervals.

3x+y=4
Using substitution
Answers
Let get x from the first equation
-4x=+2y-10
x=-1/2y + 5/2
Now substitute the x in the second equation
3(-1/2y+5/2)+y=4
-3/2y + 15/2 + y =4
Move the terms without the y to the other side
-3/2y + y = -15/2 +4
Now multiple both side by 2
-3y +2y = -15+8
-y = -7
Y = 7 (ANSWER)
Now we substitute the y in the first equation so we can get the x
x = -1/2 (7) + 5/2
