The height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning. When graphed,

the function gives a line with a slope of -0.6. See the figure below. Suppose that the height of the candle after 12 hours is 17.8 centimeters. What will be the height of the candle after 19 hours?

Answer:

  13.6 cm

Step-by-step explanation:

The slope of -0.6 tells you the change in height in 7 hours will be ...

  (-0.6 cm/h) · (7 h) = -4.2 cm

This is added to the candle height after 12 hours, so the height after 19 hours is ...

  17.8 cm -4.2 cm = 13.6 cm

For accounting purposes, the value of assets (land, buildings, equipment) in a business are depreciated at a set rate per year.
Scrat [10]

Answer:

So, option d is correct i.e,

V₀ = $393,000, b = 0.85, and the value after 7 years is $125,986.80

Step-by-step explanation:

The formula given is V(t)=V₀(b)^t

The value of V₀ (the actual worth) is:

V₀ = $393,000

The value of b is :

b= (1-15%) = (1-0.15) = 0.85

Value of assets after 7 years is:

t= 7, V₀ = $393,000, b=0.85

putting values in formula:

V(t) = Vo(b)^t.

V(7)= $393,000 * (0.85) ^ 7

V(7)= $393,000 * (0.320)

V(7)= $125986.80

So, option d is correct i.e,

Vo = $393,000, b = 0.85, and the value after 7 years is $125,986.80

Name two different numbers that round to 30 when rounded to the nearest ten
andrew11 [14]

For this case we have the following definition:

tens place: number of two digits whose absolute value is greater than zero.

Then, we have the following rounding rule:

If the previous number is greater than or equal to five, the next number increases by one unit.

We then have the following numbers rounded to 30 when rounded to the nearest ten:

26: twenty-six

27: twenty-seven

Answer:

two different numbers that round to 30 when rounded to the nearest ten are:

26: twenty-six

27: twenty-seven
