Answer:
% error = 3.3%
Step-by-step explanation:
Percent Error Formula:
% error = ( (MeasuredValue - AcceptedValue) / AcceptedValue ) * 100
% error = ( (12.7 - 12.3) / 12.3 ) * 100
% error = (0.4/12.3) * 100
% error = (0.03252033) * 100
% error = 3.25203252
% error = 3.3%

Answer:
91.66666666666667
Step-by-step explanation:
240,000/100 = 220,000/x
220,000 x 100 = 22,000,000
22,000,000 divided by 240,000 = 91.66666666666667
Answer:
This type of problem requires you to calculate the Percentage decrease
Step-by-step explanation:
Formula: Percentage Decrease=
Starting Value minus Final Value / Starting Value x 100
240,000 - 220,000 = 20,000
so 20,000/240,000 = 0.0833333333

Answer:
$37623.04
Step-by-step explanation:
The formula we'll use for this is the simple interest formula, or:
[tex]I=p*r*t[/tex]
Where:
P is the principal amount, $1088.00.
r is the interest rate, 839.5% per year, or in decimal form, 839.5/100=8.395.
t is the time involved, 4....year(s) time periods.
So, t is 4....year time periods.
To find the simple interest, we multiply 1088 × 8.395 × 4 to get that:
The interest is: $36535.04
Usually now, the interest is added onto the principal to figure some new amount after 4 year(s),
or 1088.00 + 36535.04 = 37623.04.
In a rectangle, PR=25 and the area is 168. What is the measure of PQ?

What is the classification of the triangle by its angles and by its sides?
Answer:
Step-by-step explanation:Triangles can be classified by their sides and by their angles. When classifying a triangle by its sides, you should look to see if any of the sides are the same length. If no sides are the same length, then it is a scalene triangle. If two sides are the same length, then it is an isosceles triangle.
please please help!! and explain!
angles in a triangle add up to 180
so x = 180 - ( 70 + 90 ) = 20
this is because the two other angles in the both of the identical triangles are 70 and 90

[tex]T_1 =0^{\circ}[/tex]
[tex]T_2 =-12\frac{1}{4}^{\circ}[/tex]
[tex]Time = 3\frac{1}{2}\ hr[/tex]
Required
Determine the change in temperature per hour
This is calculated as:
[tex]Rate = \frac{T_2 - T_1}{Time}[/tex]
[tex]Rate = \frac{-12\frac{1}{4}^{\circ} - 0^{\circ}}{3\frac{1}{2}\ hr}[/tex]
[tex]Rate = \frac{-12\frac{1}{4}^{\circ} }{3\frac{1}{2}\ hr}[/tex]
Convert to improper fractions
[tex]Rate = \frac{-\frac{49}{4}^{\circ} }{\frac{7}{2}\ hr}[/tex]
Express as:

Answer:
x = infinite amount of solutions
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Algebra I
TermsStep-by-step explanation:
Step 1: Define Equation
10x - 6 + 2x = 4(3x - 1) - 2
Step 2: Solve for x
Combine like terms: 12x - 6 = 4(3x - 1) - 2Distribute 4: 12x - 6 = 12x - 4 - 2Combine like terms: 12x - 6 = 12x - 6Add 6 on both sides: 12x = 12xDivide 12 on both sides; x = xHere we see that x does indeed equal x.
∴ any value x would work as a solution to the equation, hence we have infinite amount of solutions.
Answer:
The answer is infinite.
Step-by-step explanation:
So if you first simplify the problem you would have:
12x - 6 = 4 ( 3x - 1 ) - 2
I just combined like terms.
Then you distribute the 4 to the 3x and the negative 1.
So you would have 12x - 6 = 12x - 4 - 2
So once again you would combine like terms and get 12x - 6 = 12x - 6
If you simplified it out and subtracted like terms from both sides you would get 0 = 0 which is true so there is infinite solutions.
Determine whether the statement is true or false. If it is false, rewrite it as a true statement. Data at the ratio level cannot be put in order.
Answer:
False
Step-by-step explanation:
The statement is a false statement. We're asked to rewrite it as a true statement if it were false. Since it's false, we then try to rewrite it as a true statement, in so doing we are going to have it like this
"Data at the ratio level can be placed in a meaningful order."

jeremiah makes 4/5 of the free throw shots he attempts in basketball. Jeremiah likes to shoot free throws until he misses one. Let F be the number of shots it takes Jeremiah to miss his first free throw. Assume that the results of each shot are independent.
Answer:
Mean - 5
Standard Deviation - 4.5
Step-by-step explanation:
Just got it correct on Khan Academy :)
80% is her free throw shooting percentage.
What is Fraction?A fraction represents a part of a whole.
We can construct a fraction in which the numerator is how many shots she makes, and the denominator is how many shots she took overall.
We now have the following fraction:4/5
To convert this to a percentage, we want the denominator to be 20/20
4/5×20/20
80/100
0.8
Now multiply 0.8 with 100
0.8×100=80
Hence, 80% is her free throw shooting percentage.
