If they ring at 8am and you're trying to find the next time they ring do 45+45=1 hour and 30 minutes and 30+30+30= 1 hour and 30 minutes and you end up with 9:30 am. so your answer is 9:45 AM

Write each ratio statement as a fraction and reduce to lowest terms if possible:
qwelly [4]

The answers are:

18 to 24 =  \frac{18}{24} = \frac{3}{4}

5 to 15 =  \frac{5}{15} = \frac{1}{3}

14:42 =  \frac{14}{42} = \frac{1}{3}

15 cents to 18 cents = \frac{15}{18}  = \frac{5}{6}

Explanation:

To write a fraction using a ratio, simply use the first number as the numerator (top number), in this case, the numbers 18, 5, 14, and 15, and the second or biggest number as a denominator (bottom number), in this case, the numbers 24, 15, 42 and 18. This means the fractions are  \frac{18}{24},  \frac{5}{15}, \frac{14}{42} , and  \frac{15}{18}.

The second step is to reduce or simplify the fractions, which means the numbers in a fraction are divided by the same factor (a number that divides another without a remainder). Additionally, to do this, it is important to reduce the fraction to its minimum.

\frac{18}{24} divide this by 6, which is equivalent to \frac{3}{4}

\frac{5}{15} divide this by 5, which is equivalent to \frac{1}{3}

\frac{14}{42} divide this by 14. which is equivalent to \frac{1}{3}

\frac{15}{18} divide this by 3, which is equivalent to \frac{5}{6}

Tammy's home cost her S184,000. She lives in an area with a lively real estate market, and her hormincreases in value by 3.5%
Ivenika [448]

Answer:

  • D. $103800

Step-by-step explanation:

<u>Initial value of house:</u>

  • $184000

<u>Yearly increase rate of value:</u>

  • 3.5%

<u>Time </u>

  • 13 years

Since the increase is concerning the current price it would be exponential growth.

<u>The function would be:</u>

  • V(t) = 184000*(1 + 3.5/100)^t, where V is the value after t years

<u>For t= 13 we get:</u>

  • V(13) = 184000*(1.035)^13 = 287800

<u>Profit made would be:</u>

  • 287800 - 184000 = 103800

Correct option is D.
