Answer:
Step-by-step explanation:
Part A:
Given that the mattress is sold for 50% off of the retail price, let the retail price of the mattress be x, then
50% of x = 1200
⇒ 0.5x = 1200
⇒ x = 1200 / 0.5 = 2400
Therefore, the retail price of the mattress, before the discount is $2,400.
Part B:
Given that the store marks up the retail price to 150% of the wholesale price. Let the whole sale price be p, then
(100% + 150%) of p = 2400
250% of p = 2400
2.5p = 2400
p = 2400 / 2.5 = 960.
Therefore, the wholesale price, before the markup was $960
Answer:
Step-by-step explanation:
m=1, (10,5)
y=mx+b
5=1(10)+b
5=10+b
b=-5
y=x-5
I assume h is the hypotenuse on a triangle. We use trigonometric functions in order to find the value of h. Also, since side g is not specified whether it is adjacent or opposite angle f. We solve using every possible function and see from the choices the correct answer.
h = 27 sin 54 = 21.84
h = 27 cos 54 = 15.9
Therefore, most likely the correct answer is A.
Answer:
1. Top: 18 (cm²)
2. Left: 12 (cm²)
3. Front: 24 (cm²)
4. Bottom: 18 (cm²)
5. Back: 24 (cm²)
6. Right: 12 (cm²)
Surface area: 108 (cm²)
Step-by-step explanation:
You can find the surface area of this rectangular prism by using the grid.
We know that in order to find the area of a rectangle, we must multiply the length by the height. Let me make this clearer.
In the grid, the top has a length of 3 centimeters and a height of 6 centimeters. To find the area, we multiply these side lengths.
Now, we know that the area of the top is 18 centimeters.
Simply find the area of each side, then combine the areas at the end to find the <u>SURFACE</u> area.
Answer:
240
Step-by-step explanation:
Since David has 60 fewer storybooks than Huiling, take the total number of storybooks, which is 460 and minus it by 60.
460-60=400
Now, there are 5 units, 5units=400
1unit=80
Since Jenny has 3 times as many storybooks as David, Jenny has 3 units, 3unit=80x3=240
