Number of people in the office=13
Number of office lines=66
Given that all the 6 phones started ringing at once, the number of groups of 6 people that that can answer the lines will be:
13C6
=(13!)/(6!7!)
=1,716
Answer:
D. 14 times
Step-by-step explanation:
The population of New York City is about 8.18 × 10^6. This is an estimation. The population of Las Vegas is about 5.84 × 10^5. This is also an estimation. We want to determine the number of times that population of new York is more than that of las Vegas. It's like saying how many las Vegas are the in New york.
This is done by dividing the population of new York by the population of las Vegas. It becomes
8.18 × 10^6 / 5.84 × 10^5
= 14.00684931507
Approximately 14 times
Answer:
The value of 'a' will be:
Step-by-step explanation:
Given the formula
Let us solve the equation for 'a'
Flip the equation
Add -m to both sides
Divide both sides by 2
Therefore, the value of 'a' will be:
Answer:
Area and side length of rhombus.
Step-by-step explanation:
Directly proportional: If the first variable is multiplied by a constant, the other will also be multiplied by a constant.
Rhombus is a quadrilateral with equal side lengths.
Area increases with a quadratic relationship as a corresponding length increases if the angles do not change. If side length is multiplied by A, the area will be multiplied by A^2. If side length is doubled, the area will be 4 times greater.
Total cost is usually directly proportional to ticket price.
If number of tickets are doubled, the total cost will double.
Hours worked is usually proportional to money earned.
If one works twice as long, money earned will be twice as much.
Distance is proportional to time spent when speed is constant if travelling in a straight line. If time is twice as long, the distance traveled will double.
