On September 1, a dress was priced at $90. On October 1, the price was reduced by 20%. On

What percent of the original price was the FINAL price?
F.

45%
55%
60%
77.5%
J.
K.
Answer:
I wouldn't say this is entirely correct, but I think it's 45%.
Step-by-step explanation:
If you started with $90 and it was reduced 20%, than 25% MORE, the final percentage that was lowered would be the 20% and 25% added together.
The answer is 45%.
(Please do tell me if I got this wrong!!)
The original price reduced to 60%.
What is a percentage?A percentage is a ratio or number that can be expressed as a fraction of 100. Additionally, it is denoted by the symbol "%."
On September 1, a dress was priced at $90. On October 1, the price was reduced by 20%.
That means,
the price is now = $90 - (90 x 20 /100) = $72
On November 1, the price was further reduced by 25% of the October 1 price.
The price is now = $72 - ( 72 x 25 / 100) = $54
To find the percentage of original price;
The percentage of original price
= 5400 / 90
= 60%
Therefore, the final price is 60% of the original price.

The diameter of a dime is 17.91 mm. The diameter of a strand of human hair is
Answer:
The average strand of hair is 25.4μm
Step-by-step explanation:
Diameter of dime is 2.985×10² times of diameter of human hair.
The correct option is B.
What is ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given,
Diameter of dime = 17.91mm
Diameter of human hair = 6.0×10⁻²mm
Ratio of diameter of dime to diameter of human hair = 17.91/6.0×10⁻²
= 2.985×10²
Hence, 2.985×10² times of diameter of human hair is diameter of dime.

Find The Mean, Median, and mode range of 13, 25, 7, 28, 42, 7, 15, 23, 1, 17.
Step-by-step explanation:
Mean :
13 + 25 + 7 + 28 + 42 + 7 + 15 + 23 + 1 + 17.
= 178
178 ÷ 10
= 17.8
Median =
13, 25, 7, 28, (42, 7,) 15, 23, 1, 17
= 42 + 17
= 59 ÷ 2
= 29.5
Range :
42 - 1
= 41
Hope it helps :))
Answer:
Mean- 17.8 Median- 16 Mode- 17.8
Step-by-step explanation:
1. Put the numbers in ascending order.
1, 7, 7, 13, 15, 17, 23, 25, 28, 42
2. Look for the median. The median is the number located in the middle of a set of numbers. In this case, the median is going to be between 15 and 17 because they are both in the middle. This means that the median will be 16.
1, 7, 7, 13, 15, 17, 23, 25, 28, 42
3. Find the mode. The mode is the number you see the most in a set of numbers. In this case, there are two 7's so 7 is the mode of this set.
1, 7, 7, 13, 15, 17, 23, 25, 28, 42
4. Find the mean. The mean is the overall average of a set of numbers. To find the average, find the sum of all the numbers in the set and divide it by the number of integers there are. In this case, there are ten integers, so we'll find the sum (178) and divide it by 10 to get a mean of 17.8.
[tex]\frac{1+7+7+13+15+17+23+25+28+42}{10}[/tex] = 17.8
5. Find the range. The range is basically the difference between the lowest and highest values in a set of numbers. The lowest number is 1 and the highest is 42. So, we'll subtract the two to get a range of 41.
1, 7, 7, 13, 15, 17, 23, 25, 28, 42
42 - 1 = 41
A prism has a volume of 225 cubic meters.
A prism has a length of 7.5 meters, width of w, and height of 5 meters.
Which is the correct substitution for finding the width of the prism?
V = l w h. 225 = 7.5 + w + 5.
V = l w h. 5 = 15 times 225 times h.
V = l w h. 7.5 = 7.5 times w times 5.
V = l w h. 225 = 7.5 times w times 5.

x=
y=
z=
Answer:
Step-by-step explanation:
A 45 degree angle in a right triangle produces 2 equal sides. In this case z and the perpendicular line are equal. So that's were we'll start. Then you move on to the 60 degree angle to get x and y.
Finding z
z^2 + z^2 = (24√2) Combine the left
2z^2 = 24^2 * 2 Divide both sides by 2
2z^2/2 = 24^2/2
z^2 = 24^2 Take the square root of both sides
√z^2 = √24^2
z = 24
Finding x and y
The perpendicular = 24. Because it is a 60 degree angle that's given, we can do this without a calculator.
Tan 60 = opposite over adjacent
sqrt(3) = Perpendicular / z Multiply both sides by z
z*sqrt(3) = perpendicular
The above calculation tells us the perpendicular is 24
z*sqrt(3) = 24 Divide by sqrt 3
z = 24/√3
z = 24/1.73
z = 8√3
Finding x
Use Pythagoras to determine x
Perpendicular^2 + (8√3)^2 = x^2
24^2 + 8^2*3 = x^2
576 + 192 = x^2
768 = x^2
√x^2 = √768
x = 27.71

Ray M J and Ray M L are connected at point P, forming angle J M L. A ray M K sharing the same point forms a bisector. A ray M H also sharing the same point from the diagonally down from the right. The angle J M K measure 41 degrees and angle L M H measure 132 degrees.
The correct classification for the angle JML is an acute angle.
What is an acute angle?
An acute angle has a measure, or it's smaller, than a right angle.
Therefore, the acute angle is the small angle which is less than 90°
let's find the measure of ∠JML
Hence,
∠JML = ∠JMK + ∠KML
∠KML = 180 - 132 = 48 degrees.
Therefore,
∠JML = 41 + 48 = 89 degrees.
Therefore, the correct classification for the angle JML is an acute angle.

A car dealership sells SUVs and passenger cars. For a recent year, 70 more SUVs were sold than passenger cars. If a total of 340 vehicles were sold, determine the number of each type of vehicle sold.
Answer:
135 cars; 205 SUVs
Step-by-step explanation:
Let c = number of cars sold.
Let s = number of SUVs sold.
s = c + 70
c + s = 340
Substitute s in the second equation with c + 70 and solve for c.
c + s = 340
c + c + 70 = 340
2c = 270
c = 135
s = c + 70
s = 135 + 70
s = 205
Answer: 135 cars; 205 SUVs

Step-by-step explanation:
The side of the square is k.
The area of the square is k².
The diameter of the circle is k.
For a circle, radius = diameter/2.
The radius of the circle is k/2.
Formula for area of circle: A = πr².
Here, the radius, r, is k/2.
The area of the circle is π(k/2)² = (πk²)/4
The shaded area is the difference between the area of the square and the area of the circle.
shaded area = k² - (πk²)/4
We are told that the shaded area = A
A = k² - (πk²)/4
Multiply both sides of the equation above by 4.

Step-by-step explanation:
this is a nice parallelogram.
that means it has 2 pairs of equal and parallel sides (opposite of each other), 2 pairs of equal angles (also opposite of each other).
as in every quadrilateral the sum of all angles is 360°.
and because of the 2 pairs of equal (yet opposite) angles, every angle combines with one of its neighbors to 180°.
so,
(3x + 5) + (8x - 12) = 180
3x + 5 + 8x - 12 = 180
11x - 7 = 180
11x = 187
x = 17
and then the angle P is
3x + 5 = 3×17 + 5 = 51 + 5 = 56°
