If 80% of an item is $280.00, what is the original price?
Answer:
$350.00
Step-by-step explanation:
$280 = 80%
$3,5 = 1%
$350 = 100%
if $280 is 80%
then every percent is $3,5
original price is 100%
so multiply 3,5 by 100
then you'll get 350
Wendell wants to make a wooden lid for a decorative box.
The lid needs to be 6 1/2inches wide and 8 1/2inches long with sides 2 inches deep.
Part A
Find the area of wood that Wendell will need to make the lid.
Drag numbers to complete the measurements.
Each tile may be used once or not at all.
The total area of wood that Wendell will need to make the lid is 350.5 square inches.
What is Area of Rectangle?The area of Rectangle is length times of width.
Surface area of the lid = area of top + area of bottom + area of four sides
The area of the top is equal to the product of the length and width of the lid:
Area of top = [tex]6\frac{1}{2}[/tex] inches × [tex]8 \frac{1}{2}[/tex] inches
= (13/2) inches × (17/2) inches
= 221/4 square inches
The area of each side can be found by multiplying the height (2 inches) by the perimeter of the lid (which is the sum of the length and width of the lid):
Perimeter of lid = 2 × ( [tex]6\frac{1}{2}[/tex] inches + [tex]8 \frac{1}{2}[/tex] inches)
= 2 × (13/2 inches + 17/2 inches)
= 60/2 inches = 30 inches
Area of one side = 2 inches × 30 inches = 60 square inches
Since there are four sides, the total area of the sides is:
Area of four sides = 4 × 60 square inches = 240 square inches
Therefore, the total area of wood that Wendell will need to make the lid is Area of top + area of bottom + area of four sides = 221/4 + 221/4 + 240 = 221/2 + 240 = 110.5 + 240 = 350.5 square inches.

Answer:
2nd answer $625 3rd ans 7.8kg
Step-by-step explanation:
2nd answer
1 employee = 6.35$ in1 hour
therefore 100 worker = 100X6.35
= 635$
Answer:
1 = 2 7/12
2 = $625
3 = 7.8kg
4 = 21
5 = 2.82
6 = 10.09
7 = 9.02
Step-by-step explanation:
1. - 2 1/4 + 1/3 = 2 7/12
2. - 6.25*00 = $625
3. - .65*12 = 7.8kg
4 - 2.31 / .11 = 21
5. - 8.46 / 3 = 2.82
6. - 6:3 = 2, so 2 + 0.09 + 8 = 10.09

Okay, so to work this problem out, you need to know how to do probabilities.
first, calculate how many total movies there are. There are:
8 comedy movies
+5 science fiction movies
+7 adventure movies
= 20 movies total
To find out the probability of NOT watching a comedy movie, you should take the total movies minus the number of comedy movies. Doing this will give you the proportion of movies that are not a comedy movie.
total movies - comedy movies = probability of not watching a comedy
20 total - 8 comedy = 12 not comedy
So, you know there are 12 movies that are not comedies out of the 20 total movies. You should write this as a proportion: 12/20. Now, simplify:
3/5 probability that it will not be a comedy.
3/5 can also be written as 0.60 and 60%
So, your final answer is written as any of these:
0.60, 3/5, and 60%

In Ponce De Leon Park, there is a flag pole that is exactly 50 feet tall. Nearby, there is a pine tree that appears to be nearly as tall as the flag pole. On a sunny afternoon, the flag pole is casting a 15-foot-long shadow on the ground. The pine tree is casting a 12-foot-long shadow on the ground at the same time.
Answer:
10 feet higher.
Pine tree measure = 40 feet in height
Step-by-step explanation:
This is because the Flag pole of 50 feet in measure cast a shadow of 15feet and nearby to the pine tree (meaning same dilation would occur for such shadow) where pine tree shadow is given measure of 12 feet.
Flag Pole multiplier = 50 / 15 = 3 1/3
Pine Tree true measure = 12 x 3 1/3 = 40 feet in height

A recipe for modeling clay requires 1/3 cup of salt. How many recipes of clay can Carla make with 7 3/4 cups of salt?
Answer:
About 23 cups
Step-by-step explanation:
Answer:
- The error is: (31/4) (1/3)
- The correct solution is: 93/4 =23 1/4 (Carla can make approximately 23 recipes with the clay).
Step-by-step explanation:
1. Carla must divide 31/4 ÷ 1/3 as following:
- Take the reciprocal of .
- Multiply the numerators and the denominators.
Then:(31/4) (1/3) = (31)/4 (3)/1 = 93/4
2. As a mixed number: 93/4 = 23 1/4
3. Therefore, Carla can make approximately 23 recipes with the clay.
- The error is:
- The correct solution is: (Carla can make approximately 23 recipes with the clay).

Initially only 2 cups of lemon juice are required. Divided by 2 is 1.
2 + 1 = 3
3 Cups are needed.

Which polynomial does the model represent?
A black square, two white rods, three black rods, three white unit blocks and one black unit block are shown.
A. –x³ + 2x² – 3x + 2
B. x² + x – 2
C. –x² – x + 2
D. –x² + x – 2
Answer:
Step-by-step explanation:
Assume black represents negative and white positive, square is x^2, rod is x and block is number:
-x^2 +2x -3x +3 -1
= -x^2 -x + 2
The answer is C.
Use the Pythagorean Theorem to find the value of x.
Answer:
10
Step-by-step explanation:
First, when looking at a triangle, using the Pythagorean Theorem, find the longest side, which in this case, would be 26. Take the side of 24, and multiply it by itself. So, 24 x 24. Which would equal 576. Because 26 is the biggest size in length on the triangle, both 24^2 + x^2 would equal 26^2. 26 x 26 = 676. Subtract 676 from 576 and get your answer of 100. Find the square root of 100, and get your answer of 10. a^2 + b^2 = c^2

Answer:
Jim carried 4 grocery bags.
Step-by-step explanation:
16 is the total, and if you divide that up by 4, you get 4 (you divide by 4 because it is in fourths). Because Byron carried 3/4's, you multiply four by three to get twelve. There is only one more fourth to complete the whole to get to 16, so Jim is carrying four bags.
To check this, we can take Byron's 12 bags (3/4), and subtract that from 16 (4/4):
16-12=4 (1/4), so our answer is correct
Answer:
4
