\textit{internal division of a line segment using ratios} \\\\\\ P(-10,7)\qquad R(8,-5)\qquad \qquad \stackrel{\textit{ratio from P to R}}{4:5} \\\\\\ \cfrac{P\underline{Q}}{\underline{Q} R} = \cfrac{4}{5}\implies \cfrac{P}{R} = \cfrac{4}{5}\implies 5P=4R\implies 5(-10,7)=4(8,-5)

Tom, Michael and Jane visit the same sport club. Tom visits the club every 5th day, Michael every 6th day and Jane every 8th day
Sedaia [141]

Answer: December 3rd.

Step-by-step explanation:

To solve this question, we have to calculate the multiples of 5, 6 and 8 and then choose the lowest common multiple. After then, we add the number chosen to the date earlier given to derive our answer.

For Tom:

Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120

For Michael:

Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96, 102, 108, 114, 120.

For Jane:

Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120.

L. C. M = 120

It should be noted that when we use the calendar or calculate the number of days we have, August 5 will be 217 days.

The next day when the three of them will be at the sports club will be:

= August 5 + 120

= 217 days + 120 days

= 337 days

The 337th day will be December 3rd.

Sharla is 8 year older than her sister, patricia . The sum of their ages is 102.Find their ages.​
Alisiya [41]

Answer:

Patricia is 47 years old

Sharla is 55 years old

Step-by-step explanation:

Rewrite the first sentence as an equation: (S= Sharla) (P= Patricia)

S=P+8

Rewrite the second sentence as an equation:

S+P=102

1) Substitute P+8 as Sharla in the second equation:

P+8+P=102

2) Combine alike terms:

2P+8=102

3) Subtract 8 from both sides:

2P=94

4) Divide both sides by 2:

P=47

5) Substitute 47 as P in the <u>First</u> equation:

S=47+8

6) Solve:

S=55
