Multiply the original price by the markdown, then subtract the result from the original price.
2.Find the amount by which the item was marked down
Multiply the original price by the percent by which it was marked down.
Original price * markdown
80 * 20%
*don't forget to convert the percent to a decimal by dividing the percent by 100
80 * 0.2
= 16
3. Find the new price
Subtract the amount by which the product was marked down from the original price;
original_price - markdown
80 - 16
= 64

6. What is the area of a parallelogram with a base of 40 mm, a side length of 15 mm, and height of 18 mm?
7. If the height of a rectangle is 8.8 m and the base is 7.9 m, what is the perimeter of the rectangle
8. If the base of a rectangle is 23cm and the area is 354 cm2, what is the height of the rectangle?
9. What is the area of a square with a perimeter of 44 mm?
10. What is the area of a square with a perimeter of 55 cm
Answer:
Step-by-step explanation:
To find the area of a parallelogram, multiply the base by the height:
Area = base x height
Area = 6.3 m x 27.3 m
Area = 171.99 m²
To find the height of a rectangle, divide the area by the base:
Height = Area / Base
Height = 420.92 mm² / 27.4 mm
Height ≈ 15.35 mm
The perimeter of a rectangle is given by 2 times the sum of the base and height:
Perimeter = 2(base + height)
133.2 mm = 2(30.6 mm + height)
133.2 mm = 61.2 mm + 2 height
2 height = 133.2 mm - 61.2 mm
2 height = 72 mm
Height = 72 mm / 2
Height = 36 mm
To find the height of a parallelogram, divide the area by the base:
Height = Area / Base
Height = 645 m² / 61 m
Height ≈ 10.57 m
The perimeter of a parallelogram is the sum of all its sides:
Perimeter = 2(base + side length)
Perimeter = 2(32 cm + 34 cm) + 2(height)
Perimeter = 2(66 cm) + 2(19 cm)
Perimeter = 132 cm + 38 cm
Perimeter = 170 cm
To find the area of a parallelogram, multiply the base by the height:
Area = base x height
Area = 40 mm x 18 mm
Area = 720 mm²
The perimeter of a rectangle is given by the formula: Perimeter = 2(base + height)
Perimeter = 2(7.9 m + 8.8 m)
Perimeter = 2(16.7 m)
Perimeter = 33.4 m
To find the height of a rectangle, divide the area by the base:
Height = Area / Base
Height = 354 cm² / 23 cm
Height ≈ 15.39 cm
The perimeter of a square is 4 times the length of one side. Since the perimeter is given as 44 mm, we can divide it by 4 to find the length of one side:
Side length = Perimeter / 4
Side length = 44 mm / 4
Side length = 11 mm
To find the area of a square, multiply the side length by itself:
Area = side length x side length
Area = 11 mm x 11 mm
Area = 121 mm²
The perimeter of a square is 4 times the length of one side. Since the perimeter is given as 55 cm, we can divide it by 4 to find the length of one side:
Side length = Perimeter / 4
Side length = 55 cm / 4
Side length = 13.75 cm
To find the area of a square, multiply the side length by itself:
Area = side length x side length
Area = 13.75 cm x 13.75 cm
Area ≈ 189.06 cm²

Answer:
The answer is D, On average, 2 out of 10 adults visited the museum most frequently.
Step-by-step explanation:
You can find this out by finding out how many adults there was total. You would do 31+14+17+8=70 and the you can see that 14 went to the museum so it would be 14/70. This fraction simplifies to 2/10.
Tanya is training a turtle for a turtle race. For every 1/2 of an hour that the turtle is crawling, he can travel 2/23 of a mile. At what rate is the turtle crawling in miles per hour?
Answer:
To determine at what unit rate the turtle is crawling, divide 3/20 mile by 1/6 hour.
Therefore, the unit rate is 9/10 of a mile per hour
Step-by-step explanation:
The rate of turtle crawling is 4/23 miles per hour.
Given that, the time taken by turtle to crawl = 1/2 hour and number miles crawled by turtle = 2/23 mile
What is the speed?The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.
Now, Speed = Distance/Time
= 2/23 ÷ 1/2
= 2/23 × 2/1
= 4/23 miles per hour
Hence, the rate of turtle crawling is 4/23 miles per hour.

A restaurant serves a 24-fluid ounce glass of soda that is 40% ice. How many fluid ounces of soda are served
Need help its a test!!!!
Answer:
14.4 fl ounces
Step-by-step explanation:
60% of 24 is 14.4
The percentage is calculated by dividing the required value by the total value and multiply it by 100.
100% = 24 fluid ounce
60% = 14.4 fluid ounce
The amount of soda in the glass of soda is 14.4 fluid ounces.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiply it by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
A glass of soda = 24 fluid ounce
A glass of soda = Soda + Ice
The percentage amount of ice in the glass of soda = 40%
The percentage amount of soda in the glass of soda.
= 100% - 40%
= 60%
A glass of soda = 24 fluid ounce
This can be written as,
100% = 24 fluid ounce
Multiply 60/100 on both sides.
60/100 x 100% = 60/100 x 24 fluid ounce
60% = 14.4 fluid ounce
Thus,
The amount of soda in the glass of soda is 14.4 fluid ounces.

Mae Ling earns a weekly salary of $310 plus a 7.5% commission on sales at a gift shop. How much would she make in a work week if she sold $4,700 worth of merchandise?
someone please answer ASAP i'll give brainlist to the best answer <3
Answer: 662.50 dollars
==========================================================
Explanation:
If she doesn't sell a single thing, she still earns the base weekly salary of $310. This is the smallest amount she can earn per week.
If she does make sales, then she'll earn an additional 0.075x dollars where x is the amount of sales made (the total value of the merchandise). The 0.075 is the decimal form of 7.5%
In total, she makes 0.075x+310 dollars per week. In this case, she sold x = 4700 dollars worth of goods, which means,
0.075x+310 = 0.075*4700+310 = 662.50
She earned 662.50 dollars for that week.

Cube Roots of Negative Numbers.
Thank you!♡
Answer:The cube root of a negative number is a complex number because there is no real number that, when cubed, gives a negative result.
To find the cube root of -1, we can express it in exponential form as -1 = 1 * e^(iπ), where i is the imaginary unit and π is pi.
The cube root of -1 can be calculated by applying De Moivre's theorem, which states that (r * e^(iθ))^(1/n) = r^(1/n) * e^(iθ/n), where r is the magnitude and θ is the argument of the complex number.
For n = 3, the cube root of -1 becomes:
(-1)^(1/3) = (1 * e^(iπ))^(1/3) = 1^(1/3) * e^(iπ/3) = e^(iπ/3).
Therefore, the cube root of -1 is e^(iπ/3), which can also be expressed as cos(π/3) + i * sin(π/3).
In trigonometric form, the cube root of -1 is (√3/2) + i * (1/2).

Heather deposits $7000 into an account that pays simple interest at a rate of 2% per year. How much interest will she be paid in the first 3 years?
Answer:
year after 3 year(s).
The formula we'll use for this is the simple interest formula, or:
Where:
P is the principal amount, $7000.00.
r is the interest rate, 2% per year, or in decimal form, 2/100=0.02.
t is the time involved, 3....year(s) time periods.
So, t is 3....year time periods.
To find the simple interest, we multiply 7000 × 0.02 × 3 to get that:
The interest is: $420.00
Usually now, the interest is added onto the principal to figure some new amount after 3 year(s),
or 7000.00 + 420.00 = 7420.00. For example:
If you borrowed the $7000.00, you would now owe $7420.00
If you loaned someone $7000.00, you would now be due $7420.00
If owned something, like a $7000.00 bond, it would be worth $7420.00 now.

Answer:
C. A cube that is 1 yard long, 1 yard wide, 1 yard high
Step-by-step explanation:
A unit cube has a volume of 1 cubic unit.
This means that the length, width, and height are all 1 unit.
Answer choice C is the only one that has a cube with the length, width, and height at 1 unit.
This means it is a unit cube because the volume will be 1 cubic unit.
So, C is the correct answer.
