Michael bought a stereo on sale for 20% off the regular price. The regular price of the stereo was $180. What was the sale price of the stereo?
Answer:
144
Step-by-step explanation:
Take the original price and multiply by the discount
180* 20%
180 *.20
36
Subtract this from the original price
180-36 =144
The sale price is 144
The hexagon has all sides the same length and opposite sides are parallel, but is not a rhombus. Why?!
Although the sides are equal, it isn't a rhombus because there is 6 sides and not 4.

Original Price
80%
$90
Answer:
You will pay $18 for a item with original price of $90 when discounted 80%. In this example, if you buy an item at $90 with 80% discount, you will pay 90 - 72 = 18 dollars.
Step-by-step explanation:
Answer:
Original Price is $450
Step-by-step explanation:
(Discounted price) = (100 percent - discount percent) x (original price)
90 = (100%- 80%) x y
y = 90 / 0.20
= 450
Cards for Candy Two ladies played cards for candy; the winner received one piece per game from the loser. When it was time for one of the ladies to go home, one lady had won three games, while the other lady had a profit of three pieces of candy. How many individual games had they played?
Answer:
6 games
Step-by-step explanation:
if one lady had 3 pieces of candy, that means she must have gotten them from the other lady. And since the other lady had only won 3 games, that means that she must have lost an additional 3, so she had to give her candy to the other lady.
The number of individual games they played is 6 games.
How many games did they play?Given the cards for Candy two ladies played cards for candy; the winner received one piece per game from the loser. When it was time for one of the ladies to go home, one lady had won three games, while the other lady had a profit of three pieces of candy.
If one woman had three candies, it is obvious that she must have obtained them from the other woman. She had to give her candy to the other lady because she had only won three games, implying that she must have lost three more.
Therefore, the number of individual games they played is 6 games.

what is causation in a scatter plot
Answer:
A scatter plot displays data about two variables as a set of points in the x y x y x y -plane and is a useful tool for determining if there is a correlation between the variables. Causation means that one event causes another event to occur. Causation can only be determined from an appropriately designed experiment.
Step-by-step explanation:
Example: Correlation between Ice cream sales and sunglasses sold. ... Causation takes a step further than correlation. It says any change in the value of one variable will cause a change in the value of another variable, which means one variable makes other to happen. It is also referred as cause and effect.

Given the equation (x - 1) ^ 2 + (y + 20) ^ 2 = 196 identify the center and radius
Answer & Step-by-step explanation:
In order to solve this problem, it is important that we know the original form of this equation.
(x - x1)² + (y - y1)² = r²
The equation we are given is: (x - 1)² + (y + 20)² = 196
Now that we know the original equation and the given equation, then we can conclude that the center of the circle is (1, -20). We can find the radius by calculating the square root of 196.
√196 = 14
So, the radius is 14.
Now, based on the given information, we know that the center of the circle is (1, -20) and the radius of the circle is 14.

The dimensions of the Surf City Community Pool are shown below.
How many cubic meters of water are needed to fill the entire pool?
A: 210
B: 525
C: 735
D: 1050
Answer:
C: 735
Step-by-step explanation:
We can split the pool into two 3D shapes.
The first rectangular prism on the left would equal 7 * 5 * 15 = 525 cubic meters
The second rectangular prism on the right would equal 7 * 2 * 15 =210 cubic meters.
In total, 525 + 210 = 735 cubic meters
Joshua owns a trucking company. For every truck that goes out, Joshua must pay the driver $25 per hour of driving and also has an expense of $2 per mile driven for gas and maintenance. On one particular day, the driver drove an average of 50 miles per hour and Joshua's total expenses for the driver, gas and truck maintenance were $625. Write a system of equations that could be used to determine the number of hours the driver worked and the number of miles the truck drove. Define the variables that you use to write the system.
Let h= the number of hours the driver drove
Let m= the number of miles driven
25h+2m=625
m=50h
System of equations are 25x + 2y = 625 and y = 50x
Where x represents number of hour of driving and y represent number of mile driven for gas and maintenance.
Since, Joshua pay the driver $25 per hour of driving
So for x hours pay $ 25x
And also has an expense of $2 per mile driven for gas and maintenance
So for y miles pay $ 2y
Thus, for the driver drove an average of 50 miles per hour
Equation is, y = 50 x
And since, Joshua's total expenses for the driver, gas and truck maintenance were $625.
So equation is, 25x + 2y = 625

Answer: X=4 ✌️
Step-by-step explanation:
what is the equation of a line that passes through the point (0,8) and is parallel to a line with a slope of 4/5?
Answer: The answer is y = 4/5x + 8.
Step-by-step explanation:
There is good reasoning behind why this is the answer. First, if you recall, parallel lines must have the same slope or they will at some point meet. With this information, you can pull from the given material that the slope for the equation you are trying to gather is 4/5.
Then, you can use the given point to find the y-intercept because the x-coordinate is 0 (directly on the y-axis) and your y-coordinate is 8. Your y-intercept is placed as a positive or negative value at the end of the equation (if in slope-intercept form), and because the 8 in the ordered pair is positive, you just need to add +8 to your equation.
With this information, you can conclude that the equation is y = 4/5x + 8.

Can someone help me with this question.
Answer:
Option A
Step-by-step explanation:
If a football team gains 15 yards on a play, it will be recorded as '+ 15' or '15'.
All other options would be represented by '-15', and not '15' that is asked in the question. A withdraw is taking away money, a number 'below zero' would be negative, and losing 15 points would be represented as '-15'.
Option A should be the correct answer.
Answer:
The answer to your problem is Option A or 1: A football team gains 15 yards on a play.
Step-by-step explanation:
This is the answer because all of the other situations have an integer of -15. Like LOSING points, or 15 meters BELOW all signify that those situations include a negative number. Your question is asking for a positive 15 not negative so Option 1 is the correct answer.

PLEASE HELP. BEST ANSWER GETS BRAINLIEST. Find x in the following right triangle
Answer:
12 dm
Step-by-step explanation:
Use the Pythagorean Theorem to find the missing length of the right triangle:
[tex]a^2+b^2=c^2[/tex]
We are given the hypotenuse's length of 13 dm, and a leg length of 5 dm.
Let the missing leg be 'b':
[tex]5^2+b^2=13^2\\\left \{ {{5^2=25} \atop {13^2=169}} \right. \\25+b^2=169\\25-25+b^2=169-25 \leftarrow \text{Subtraction Property of Equality} \\b^2=144\\\sqrt{b^2}=\sqrt{144}\leftarrow\text {Square Root Property of Equality}\\ \boxed{b=12}[/tex]
The missing side length should be 12 dm.
Answer:
12 dm
Step-by-step explanation:
We can use the Pythagorean theorem since this is a right triangle
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
5^2 + x^2 = 13^2
25 + x^2 =169
Subtract 25 from each side
x^2 = 169-25
x^2 = 144
Take the square root of each side
sqrt(x^2) = sqrt(144)
x = 12
