Answer:
A: 70% B: 64%
Step-by-step explanation:
A CD usually sells for $14.00. If the CD is 20% off, and sales tax is 7%, what is the total price of the CD, including tax?
Answer:
the total price of the CD including tax is $11.984
Step-by-step explanation:
The computation of the total price of the CD including tax is shown below:
The Selling price of the CD is $14
CD is 20% off
And, the sales tax rate is 7%
So, the total price of the CD is
= ($14 - $14 × 20%) × (1.07)
= $11.2 × 1.07
= $11.984
Hence, the total price of the CD including tax is $11.984
Explain how to find a measure of angle ACD
without repositioning the protractor
Answer:
60 degrees
Step-by-step explanation:
ACD and ACB are complementary angles. Find ACB=30 degrees. Subtract 30 from 90 degrees. ACD=60 degrees.
Answer:
ACD=60
BCA=30
BCD=90
90-30=60
Jack pasted 2 leaves on each picture he made. He used 6 in all. How many pictures did jack made?
Answer:
Jack made 3
Step-by-step explanation:
You know why? The reason is he pastes 2 for each picture and he used all 6 so what is 2*3= 6 So that concludes that he made 3 pictures

PLEASE HELP WORTH 16 POINTS WILL REPORT LINKS
Answer:
Angle A = 30.8
Angle B = 33.2
Step-by-step explanation:
180 - 116 = 64
This means that the other two angles need to add up to 64.
I just plugged in numbers until it worked.
I got that x = 14.6
2x + 4
2(14.6) + 4
29.2 + 4
33.2
3x - 13
3(14.6) - 13
43.8 - 13
30.8
Those are your angles. To make sure they are correct you just need to add up all the angles and make sure that they equal to 180.
116 + 33.2 + 30.8 =
180

which property of equality should you use to solve the equation for x? -3x = 21
A. The division property of equality
B. The subtraction property of equality
C. The addition property of equality
D. The multiplication property of equality
Answer:
A. The division property of equality
Step-by-step explanation:
To get x you need to find a way to get it by itself, which can be done by dividing -3 from both sides of the equation (which is the division property of equality).
For example,
-3x=21
/-3 /-3
x=21/-3
x=-7
write the sentence as an equation. 153 added to n is the same as 143
Answer:
10
Step-by-step explanation:
153 - 143 = 10 (I'm not sure if this helped)
Answer:
n + 153 = 143
Step-by-step explanation:
In this sentence, we can use the keywords used to find the operations used in its equation form. The first part has the words "added to." This tells us we need to add. So, on one side of the equation, we have n plus 153. This is the same as, or equal to, 143.
n plus 153 is equal to 143.
n + 153 = 143
The answer is n + 153 = 143.
Good luck ^^
yeah the picture sums it up, I just dont remember how to do this
Answer and Step-by-step explanation:
To find the length of AB, we have to use Distance Formula.
Distance Formula takes two points on a graph, and puts it into the following formula to calculate the distance between those two points.
The formula:
D = [tex]\sqrt{(x_{2} - x_1)^2 + (y_2 - y_1)^2 }[/tex]
Where:
D = The Distance between two points
[tex]x_2[/tex] = The x value of the second point
[tex]x_{1}[/tex] = The x value of the first point
[tex]y_2[/tex] = The x value of the second point
[tex]y_{1}[/tex] = The x value of the first point
Point A will be the first point and point B will be the second point. All we have to do now is plug those points into the formula and solve.
[tex]\sqrt{(10 - 5)^2 + (0 - 10)^2 }\\\\\\\\\sqrt{(5)^2 + (- 10)^2 }\\\\\\\\\sqrt{25 + 100 }\\\\\\\\\sqrt{125}\\\\\\\\\sqrt{125} = 5\sqrt{5}[/tex]
The length of side AB is [tex]5\sqrt{5}[/tex] units, or 11.18 units.

On a recent survey, 40% of the 900 people surveyed preferred running.
How many people preferred running?
Answer: 550
Explanation:
Well first, you need to solve 40 percent of 900 (which is 360) then subtract it from the main amount (900)
So 900-360
Answer:
360
Step-by-step explanation:
So we have 40% and 900 people. Before we ask ourselves what is 40 percent of 900, lets ask ourselves what is 10 percent. So 10 percent of 900 would be 90 because you have to move the decimal point 1 unit to the left.
Now, 40 percent is 4 times the value of 10 percent so 40 percent of 900 has to be 360, because 90 times 4 is 360.
And you can check it by multiplying 900 x .40 which would be 360
Hope this helped, good luck :)

You have a poster that is 5 feet by 3 feet. You want to put a frame, with a uniform width, around the picture. The poster and the frame must have an area of 24 square feet. Find the width of the frame.
Please don't give me credit, but I want to say that;
1. You need a picture attached to this
2. Make sure you add if 5 feet is the length or width, in addition to the 3 feet
3. The width can't be a negative value, so eliminate the negative answers
4. For the second answer, why is there a coma preceding another value? The width can can only be one value
You can add all these elements

Answer:
x = 10.3
y = 5.8
Step-by-step explanation:
To find both x and y, you can use the formula [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
a and b would be the sides that touch the right angle
so to find x, you would do [tex]9^{2}[/tex] + [tex]5^{2}[/tex] = [tex]x^{2}[/tex]
this would be: 81 + 25 = [tex]x^{2}[/tex]
then add it and you get: 106 = [tex]x^{2}[/tex]
now do the square root of 106 to get: 10.3 = x
Now plug in your other values to get y: [tex]5^{2}[/tex] + [tex]3^{2}[/tex] = [tex]y^{2}[/tex]
do the same thing here: 25 + 9 = [tex]y^{2}[/tex]
add your numbers: 34 = [tex]y^{2}[/tex]
square root 34: 5.8 = y
the coordinates of the points A and B are (0,-2) and (3,0), what is the y intercept of the line AB
Answer:
The y-intercept of points A and B is -2.
Step-by-step explanation:
Point A is the y-intercept. You can tell by looking at the x and seeing that it is 0. This means the point is the y-intercept.
Hope this helps!
-Luna
Answer:
-2
Step-by-step explanation:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis). To solve this question, first, find the slope, then, plug one of the given points into the equation to isolate b.
1) Find the slope (m)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the given points (0,-2) and (3,0)
[tex]m=\frac{0-(-2)}{3-0}\\m=\frac{0+2}{3}\\m=\frac{2}{3}[/tex]
Therefore, the slope of of the line is [tex]\frac{2}{3}[/tex]. Plug this into [tex]y=mx+b[/tex] as m:
[tex]y=\frac{2}{3} x+b[/tex]
2) Find the y-intercept (b)
[tex]y=\frac{2}{3} x+b[/tex]
Plug in one of the given points: (0,-2) or (3,0)
[tex]0=\frac{2}{3} (3)+b\\0=2+b\\b=-2[/tex]
Therefore, the y-intercept of the line AB is -2.

HELP ASAP!!!
a bike rental company charges $12, which includes the first 30 minutes of biking. thereafter, the company charges an additional $0.25 per minute. write a numeric sequence for the first 5 minutes of the 30 minutes.
Answer:
0.4, 0.8, 1.2 ,1.6 ,2.0
Step-by-step explanation:
First we have to find what the question is really asking and get rid of unwanted or not needed information. It is asking to write a numeric sequence for the first 5 minutes of the 30 minutes.
Second we need to find the pattern. So lets divide $12 by 30. That will equal 0.4 a minute.
Last we add 0.4 for each minute. 0.4 is the first, then 0.8 is 2 minutes, then 1.2 and etc.
The numeric sequence is 0.4, 0.8, 1.2 ,1.6 ,2.0
The calculation is as follows:
Here we have to divide $12 by 30. That will equal 0.4 a minute.
Now if we add 0.4 for each minutes
So the series be like
0.4 for the first, 0.8 is 2 minute and so on.
