Answer:
The range is 17
Step-by-step explanation:
67, 63, 72, 62, 64, 79, 74, 66
To find the range of the data, take the largest number and subtract the smallest number.
The largest number is 79
The smallest number is 62
79-62 = 17
The range is 17
A used-car salesperson purchased
a car for $4000 and sold it for 40%
more. What was the selling price of
the car?
Answer:
5,600 dollars he sold it for
Step-by-step explanation:
Basically if you cross multiply, you'll do 4,000 times 40. Then divide what you get from multiplying by 100, so do 160,000 divided by 100 in this case. Then when you get that 1,600, it isn't the final step. Lastly, you'll have to add 1,600 on to 4,000 to get the markup selling price. :)
N January, the price of a dozen eggs at a grocery store was $0.89. By June, the price had increased to $0.99. What was the percent of increase in the price, to the nearest tenth of a percent?
The initial price of eggs is $0.89 which is then increased to $0.99, so the percentage increase in the price is 11.23%.
What is Percentage?The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.
As per the given data in the question,
The price of dozen eggs = $0.89
The price increase by June = $0.99
The percentage increase in the price,
% increase = (0.99 - 0.89)/0.89 × 100
% increase = 11.2%
Therefore, the increase is 11.2%.

Dexter has a gift card for $20.00 to an electronics store. He also has a coupon for 25% off his entire purchase, so he will be paying 75% of the total cost. He plans to buy a video game for $10.00 and batteries for $2.00. Select the equation that represents how much money will be left on his gift card after his purchases if x represents his remaining balance.
What is the equation that represents his remaining balance?
Answer:
Step-by-step explanation:
x=20(.75)+2+10 (or 12 if it says that)
Answer:
The linear equation that represent the situation is [tex]x=20-0.75(10+2)[/tex]
The remaining balance on his gift card is $11
Step-by-step explanation:
Let x represent the remaining balance.
We know that the linear equation that represent the situation is equal to[tex]x=20-0.75(10+2)[/tex]
Solve
[tex]x=20-0.75(12)[/tex]
[tex]x=20-9[/tex]
x=$11

Prove or disprove the figure defined by points A, B, C, d is a rhombus
Answer:
It is not a rhombus, because all the internal angles are equal.
Step-by-step explanation:
A rhombus is a figure that has four sides of equal length, and 2 internal angles that are smaller than the other two internal angles.
First, let's look at figure ABCD.
We can see that all the sides have equal length by just counting the number of squares that each side takes (each side is 12 units long)
So now we need to see the angles.
Remember that if two lines are perpendicular, then the angle formed by those two lines is exactly 90°.
We can see that the segment BC is horizontal (the y-value of B is the same than the y-value of C)
While the segment CD is vertical (the x-value of C is the same than the x-vale of D)
Then one segment is horizontal, and the other is vertical, which means that the segments are perpendicular, thus the angle C is 90°.
Now we can do the same for segments CD and DA
We already know that CD is a vertical segment.
For segment DA we can see that the y-value of D is the same as the y-value of A, then this segment is horizontal, this means that segments CD and DA are perpendiculars, which means that D = 90°.
Because DA is parallel to BC, and CD is parallel to BA, we can conclude that:
A = 90°
B = 90°
Then all the angles are equal, so this is not a rhombus. (it is a square)

Completely simplify the rational expression LaTeX: \frac{7x}{3y} + \frac{12x}{9y}
Answer:
[tex]\frac{11x}{3y}[/tex]
Step-by-step explanation:
[tex]\frac{7x}{3y} + \frac{12x}{9y}[/tex]
To add the two fractions, you need a common denominator. In this case, the lowest common denominator (LCD) is 9y. That's because 9y is divisible by both 3y and 9y.
The first fraction must be changed so that its denominator is 9y. Do this by multiplying both numerator and denominator by 3.
[tex]\frac{7x}{3y}\cdot\frac{3}{3}+\frac{21x}{9y}=\frac{21x}{9y}+\frac{12x}{9y}\\=\frac{21x+12x}{9y}\\=\frac{33x}{9y}[/tex]
Finally, this answer can be simplified ("reduced") by dividing both numerator and denominator by 3, their greatest common factor.

If 3(2x) - 4(3x) + 3 = 0. Find the possible values of x
pls help
Answer: x=1/2=0.5
Step-by-step explanation:
Given
3(2x) - 4(3x) + 3= 0
Expand parenthesis
6x - 12x + 3 = 0
Combine like terms
-6x + 3 = 0
Subtract 3 on both sides
-6x + 3 - 3 = 0 - 3
-6x = -3
Divide -6 on both sides
-6x / -6 = -3 / -6
x = 1/2 = 0.5
