23 20' 48" is the same as _____. Round to the nearest hundredth of a degree.

boyakko [2]

So this is read as 23 degrees, 20 minutes, and 48 seconds. Each degree has 60 minutes and each minute has 60 seconds, somewhat like time. You must start from right to left for this to work. This may seem complicated but the way to find this is as follows:
23+(20+(48/60))/60. A simpler way to see this is by first taking 48/60 which is .8. Now you take 20+.8 which is 20.8 and you divide it by 60 once more. This comes out to be approximately .35. Now you have converted the seconds and minutes to degrees so you add 23+.35 which is 23.35. Therefore your answer is 23.35 degrees.

Answer:

$x=2\\y=22\\or\\(2,22)$

Step-by-step explanation:

$x+y=24\\y=11x$

Subtitute y in the first equation.

$x+y=24\\x+11x=24\\12x=24\\x=\frac{24}{12}\\ x=2$

Now replace x in either equation to find y.

$y=11x\\y=11(2)\\y=22$

A young couple purchases their first new home in 2011 for $95,000. They sell it to move into a bigger home in 2018 for $105,00

mart [117]

Given:

The value of home in 2011 is $95,000.

The value of home in 2018 is $105,000.

To find:

The exponential model for the value of the home.

Solution:

The general exponential model is

$y=ab^x$ ...(i)

where, a is initial value and b is growth factor.

Let 2011 is initial year and x be the number of years after 2011.

So, initial value of home is 95,000, i.e., a=95,000.

Put a=95000 in (i).

$y=95000b^x$ ...(ii)

The value of home in 2018 is $105,000. It means the value of y is 105000 at x=7.

$105000=95000b^7$

$\dfrac{105000}{95000}=b^7$

$\dfrac{21}{19}=b^7$

Taking 7th root on both sides, we get

$\left(\dfrac{21}{19}\right)^{\frac{1}{7}}=b$

Put $b=\left(\dfrac{21}{19}\right)^{\frac{1}{7}}$ in (ii).

$y=95000\left(\left(\dfrac{21}{19}\right)^{\frac{1}{7}}\right)^x$

$y=95000\left(\dfrac{21}{19}\right)^{\frac{x}{7}}$

Therefore, the required exponential model for the value of home is $y=95000\left(\dfrac{21}{19}\right)^{\frac{x}{7}}$ , where x is the number of years after 2011.
