Step-by-step explanation:
Jeans cost $38. They are on sale for 45% off. What is the sale price?
Show your work, please
Answer:
$20.9
Step-by-step explanation:
First you find what 45% of the cost is:
0.45 x 38 = 17.1
Then, because this is a special/decrease in original price, you subtract:
38 - 17.1 = 20.9
$20.9
An auto dealer reduces the prices on the cars on the sales lot. The owner of the lot is planning on lowering the price of the cars by 4% each week. The original price was $22,000. B. Write the recursive routine.
How does knowing the coordinates of a point P in the Cartesian plane help you determine the trigonometric ratios associated with the angle formed between the initial and terminal arm for the angle? Use an example to help you explain.
The cosine and the sine of the angle are the x and y coordinates of P, respectively
The relationship between the coordinates and trigonometry ratiosAssume that the coordinate of a point P is:
P = (x,y)
The trigonometry ratios are represented using:
(cos(t), sin(t))= (x,y)
Where t represents the angle formed between the initial and terminal arm.
Hence, the cosine and the sine of the angle are the x and y coordinates of P, respectively

Answer:
(a) Grade 6
Step-by-step explanation:
You want to know which grade (6 or 7) has the higher mean score, based on the given dot plots.
RangeThe scores of Grade 6 range from 70 to 100. Those of grade 7 range from 50 to 80.
MeanBoth distributions are approximately symmetrical, but have slightly more scores farther below the middle of the range than above. This means the mean in each case will be slightly below the middle of the range.
Even so, the mean of Grade 6 scores will be substantially above the mean of Grade 7 scores. Grade 6 has the higher mean score.
__
Additional comment
Assume the mean of Grade 6 is 85, the middle of the range of scores. Subtract the fewest number of dots (4) from each column, and we have 2 scores 15 units below that assumed mean, and 2 scores at 5 units above that assumed mean. The total of these is 2(-15) +2(+5) = -20. This tells us the actual mean of Grade 6 scores is -20/20 = -1 from the assumed mean of 85. The Grade 6 mean is 84. This is higher than any Grade 7 score, so Grade 6 must have the higher mean.

Dana plans to use a survey of 60 randomly selected students at her school to predict the percentage of the 900 students at her school who will attend next week's school dance. How can Dana change her data collection plans to make her prediction closer to the actual result?
Answer:
See below ~
Step-by-step explanation:
Dana takes a survey of 60 students out of 900 total to see how many will attend the dance.
Based on whatever result she gets out of the 60 students, she can take that number and multiply it by 15 to get a closer prediction to the actual result.
This is because 60 x 15 = 900We are basic taking a ratio of the smaller portion so we can estimate the value of the larger groupIf your good at geometry please help me!
Jada's claim as a conjecture would be:
"All the segments in Δ ABC are parallel to the corresponding segments in Δ A'B'C' because both triangles are dilated from center P".
What is the implication of a dilation?
Whenever a shape is a dilation of another, we agree that the current shape and the dilated image's corresponding side lengths are in the same proportion and are all associated by the same scale factor, k.
What is the proof?
Attached are the images showing the parallelity of the segments and their corresponding lines.
Image 1 shows that Δ ABC and Δ A'B'C' are dilated from center p.Image 2 shows that Lines AB and A'B' run parallel to one another.Image 3 shows that lines CB and C'B' run parallel to one another.Image 4 shows that lines AC and A'C' run parallel to one another.
Hence, from the above, we can confirm that the above conjecture is true.

find the height and area of the equilateral triangle
As here we are given with an equilateral triangle, whose side is 3 cm, and we need to find the height and area of the equilateral triangle. So, for this let's recall that, the area of any equilateral triangle with side a is given by ;
[tex]{\boxed{\bf{Area_{(Equilateral\:\: Triangle)}=\dfrac{\sqrt{3}}{4}a^{2}}}}[/tex]So, if we substitute a = 3, in our Formula, it will yield to
[tex]{:\implies \quad \sf Area_{(Equilateral\:\:Triangle)}=\dfrac{\sqrt{3}}{4}(3)^{2}}[/tex]
[tex]{:\implies \quad \sf Area_{(Equilateral\:\:Triangle)}=\dfrac{\sqrt{3}}{4}(9)}[/tex]
[tex]{:\implies \quad \boxed{\bf{Area_{(Equilateral\:\:Triangle)}=\dfrac{9\sqrt{3}}{4}\:\:cm^{2}}}}[/tex]
Now, as we know that, for any triangle we also have a formula that is ;
[tex]{\boxed{\bf{Area_{(Triangle)}=\dfrac{1}{2}\times Base\times Height}}}[/tex]Now, Here as the triangle is equilateral, so it's base will just be same 3, and if we let height be H, so we will be having
[tex]{:\implies \quad \sf \dfrac{1}{2}\times 3\times H=\dfrac{9\sqrt{3}}{4}}[/tex]
[tex]{:\implies \quad \sf H=\dfrac{9\sqrt{3}}{4}\times \dfrac23}[/tex]

If a baseball card appreciates exponentially in value by 50% over 10 years, what is its annual appreciation (growth) rate? Please use a calculator, and answer to the nearest whole percent.
Using an exponential function, it is found that it's annual growth rate is of 4%.
What is an exponential function?An increasing exponential function is modeled by:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which:
A(0) is the initial value.r is the growth rate, as a decimal.In this problem, the card appreciates exponentially in value by 50% over 10 years, hence:
A(10) = 1.5A(0).
Thus:
[tex]A(t) = A(0)(1 + r)^t[/tex]
[tex]1.5A(0) = A(0)(1 + r)^{10}[/tex]
[tex](1 + r)^{10} = 1.5[/tex]
[tex]\sqrt[10]{(1 + r)^{10}} = \sqrt[10]{1.5}[/tex]
1 + r = 1.04.
r = 0.04.
0.04 x 100% = 4%.
It's annual growth rate is of 4%.
