Answer:
$131.25
Step-by-step explanation:
Take the $175 price and divide it by 0.25, which is the decimal version of 25%. You should get 43.25 which is 25% of 175. Then subtract 43.25 from 175 to get the final answer of $131.25 for the CD player if Martin buys it on Wednesday.

Answer:
Step-by-step explanation:
The answer choices don’t make sense. The volume of a cylinder of height 45mm and radius 5mm = π5²*45 = 1125π mm³.
Three of the answer choices are larger than 1125π.
:::::
volume of one cone = πr²h* ⅓
Volume of cylinder section = πr²h
Total volume = πr²h*⅔ + πr²h = πr²h*5/3 = π5²*15*5/3 = 625π
Answer:
226 cm^2
Step-by-step explanation:
It’s literally a rectangular prism If you put it together. The side with 2 cm and 11 cm , the surface area is 22 and since this is a rectangular prism, that means there is a second of the same kind. Then you get the larges box, since you know that the top side is 11 and the left side is 7, you multiply that * 2 which you then get 154. You add that up with the side that you solved before so 154 + 44 = 198. You then figure out the left side 7 * 2 * 2 (because there are two of them). 28 + 198 = 226 cm^2.
Answer:
68.04 cm^3
Step-by-step explanation:
The volume of the prism is given by
V = Bh
where B is the area of the base and h is the height
B - area of the triangle
B = 1/2 bh = 1/2 (5.4) (3.6) = 9.72
The volume is
V = 9.72*7
68.04 cm^3
