Large fluffy towels were on sale at a discount of 30%. If the sale price was $8.40, what was the original price?
Answer:
$ 12
Step-by-step explanation:
Think that, Original price of a towel is $ 100
Using the above we can create a equation like this. Let the Original price of the towel given in the question be x.
Original price Discount Sale price
100 30 70
x 8.40
Now let's make an equation like this,
[tex]\frac{100}{x} =\frac{70}{8.40}[/tex]
Use cross multiplication and solve for the x
100 × 8.40 = 70 x
[tex]840=70x[/tex]
[tex]\frac{840}{70} =\frac{70x}{70}[/tex]
[tex]x=12[/tex]
Therefore, the original price is $ 12

A company has developed a training procedure to improve scores on the
SAT. Following the training, 100 high school students take the SAT. The average math score is 517, with s = 90. Assuming u = 500 for the math SAT, test
the null hypothesis. Did the training significantly improve scores (a = .05,
directional)?
Answer:
The calculated t-test = 1.717 < 1.6604 at 0.05 level of significance
Null hypothesis is accepted at 0.05 level of significance
A company has developed a training procedure is significantly improve scores
Step-by-step explanationStep(i):-
Given sample mean (x⁻ ) = 517
sample standard deviation (s) =90
Mean of the Population (μ) =500
Null Hypothesis :- H₀ : (μ) =500
Alternative Hypothesis : H₁ : μ ≠ 500
Step(ii):-
Test statistic
t = \frac{x^{-} -mean}{\frac{s}{\sqrt{n} } }
t = \frac{517 -500}{\frac{90}{\sqrt{100} } }
t = 1.717
Level of significance
∝ = 0.05
t₀.₀₅ = 1.6604
The calculated t-test = 1.717 < 1.6604 at 0.05 level of significance
Conclusion:-
Null hypothesis is accepted at 0.05 level of significance
A company has developed a training procedure is significantly improve scores

C.
Principal = $220, Interest = $200
D.
Principal = $220, Interest = $20
what is the answer.
Answer:
B. Principal = $200, Interest = $20Step-by-step explanation:
Principal + Interest = TotalWe have:
Principal = 200 and Total = 220The interest is:
220 - 200 = 20Correct choice is B

Does anyone know what the slope for C = 22.5 - (1/160)m
The slope of the linear equation, [tex]C = 22.5 - (\frac{1}{160}) m[/tex], is: [tex]-\frac{1}{160}[/tex]
Recall:
A linear equation in slope-intercept form is given as: y = mx + b."m" is the slope."b" is the y-intercept.Thus, given the linear equation:
[tex]C = 22.5 - (\frac{1}{160}) m[/tex],
C represents y
m represents x
[tex]-\frac{1}{160}[/tex] represents the slope (m)
22.5 represents b.
Therefore, the slope of the linear equation, [tex]C = 22.5 - (\frac{1}{160}) m[/tex], is: [tex]-\frac{1}{160}[/tex]

a 6-pack of undershirts cost $13.98 this $3.96 less than the cost of buying 6 individual shirts. if each undershirts costs the same amount, how much does each undershirts cost when purchased individually
Answer:
Each undershirt costs $2.99 when purchased individually.
Step-by-step explanation:
The problem says that $13.98 is $3.96 less than the cost of buying 6 individual shirts which means that the total cost of buying 6 individual shirts is $17.94.
To find the price of 1 individual shirt, you divide 17.94 by 6. When you do this, you get $2.99. $2.99 is the cost of each undershirt when purchased individually.

As mentioned in the question, a loan of $4500 is given at an interest rate of 12% compounded each year.
What is compound interest?Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.
Here
(a)
The amount owed at the end of 1 year
= 4,500 × 12/100
= 540
Amount = 540+4,500
= $5,040
(b)
The amount owed at the end of 2 years
= 5,040 × 12/100
= 604.8
Amount = 5040 + 604.8
Amount = $5644.8

∠A and \angle B∠B are supplementary angles. If m\angle A=(8x-25)^{\circ}∠A=(8x−25) ∘ and m\angle B=(7x-5)^{\circ}∠B=(7x−5) ∘ , then find the measure of \angle B∠B.
An38
Step-by-step explanation:
The measure of angle B is 93°
Here,
∠A and ∠B are supplementary angles.
∠A = (8x - 25)° and ∠B = (7x - 5)°
We have to find ∠B.
What are Supplementary angles?
Two Angles are Supplementary when they add up to 180 degrees.
Now,
∠A and ∠B are supplementary angles.
Hence, ∠A + ∠B = 180°
Here, ∠A = (8x - 25)° and ∠B = (7x - 5)°
Put in above equation we get;
(8x - 25)° + (7x - 5)° = 180°
15 x - 30 = 180
15 x = 210
x = 14
So, Measure of ∠B = (7x - 5)° is;
∠B = (7x - 5)° = ( 7 * 14 - 5) = 98 - 5 = 93°
Hence, The measure of angle B is 93°.

Answer:
ST = 164.21 m
Step-by-step explanation:
The fraction RU/UV have to be equal to RS/ST, because the triangles are similar:
190/120 = 260/ST
Multiply both sides by ST:
190ST/120 = 260
Multiply both sides by 120:
190ST = 260•120
Divide both sides by 190:
ST = 31200/190
ST = 164.21 m

The rest of the graphs fail the vertical line test. This means some inputs (x values) contain more than one output (y value).
Answer:
C
Step-by-step explanation:
If a vertical line intersects the graph in some places at more than one point, then the relation is NOT a function.
answer choices A, B, and D intersect at more than one point vertically. Therefore, C is the correct answer.

how to find domain and range of a function
Answer:
The domain is found depending on the information you're given. In a table, the domain is found by taking all the x values given and listing them least to greatest. Same with ordered pairs. In a graph, the domain is found by first seeing if there are any restrictions and then find the x values that work and have one output.
The range is found the same way, but with the y values.
