Answer: 2 inches, 3 inches, or 3.125 and 2.083


Explanations:
The simplest way is to take 20% of the 2.5 inches and go that much above & below 2.5 inches.

2.5 x 20% = 2.5 x 0.20 = 0.5

So 2.5 - 0.5 = 2 inches was predicted
And 2.5 + 0.5 = 3 inches was predicted.

The more complicated way is to see number + 20% of that number = 2.5, and what number - 20% = 2.5.

Which solution sounds more like what you’re doing in class right now?

If it’s the more complicated way:

0.8x = 2.5 (80% of the predicted rain value equals 2.5)
x = 3.125 inches was predicted

1.2x = 2.5 (120% of the predicted rain value equals 2.5)
x = 2.083 inches was predicted

Sorry, this is probably confusing. Let me know what questions you have.

A TV can be purchased from the manufacturer for $160. An online retailer sells the same
Triss [41]

Answer:

(a) $208

(b) $224.

Step-by-step explanation:

A TV can be purchased from the manufacturer for $160. An online retailer sells the same TV with a 30% markup from the manufacturer’s price, and a superstore sells the same TV for a 40% markup from the manufacturer’s price.

(a) Therefore, the price of the TV when purchased online will be  

160(1 + \frac{30}{100}) = 208 dollars (Answer)

(b) And the price of the same TV when purchased at the superstore will be  

160(1 + \frac{40}{100}) = 224 dollars (Answer)

The perimeter of the rectangle below is 42 inches. Find the value of X.<br> Please help
nirvana33 [79]

Answer:

x = 4

Step-by-step explanation:

42 = 5x + 5x + ( x - 3 ) + ( x - 3 )

42 = 12x - 6

48 = 12x

x = 4

Perimeter is the length around the rectangle (or any other shape). For rectangles, it's found by adding the side lengths. In this case, it required algebra to solve for x.

How do you know where and when the graph crosses the horizontal asymptote?
Genrish500 [490]
The horizontal asymptote is the line which the curve approaches to cross but never crosses the boundary. The horizontal asymptote can be identified when the exponent in the denominator<span> of the function is larger than the exponent in the numerator. If not, no horizontal asymptote exists. WHen there is, we equate the denominator to zero and get x</span>
