A school club uses a telephone chain to inform members of changes in plans. The club president calls 2 members, each of whom calls 2 members, and so on. The process must be repeated 5 times. How many members are in the club?
Answer:
63 members
Step-by-step explanation:
Since each person calls 2 persons each, there is an exponential increase of 2 for each level. Since it starts with the president as 1 person, and increases exponentially by 2 for each level of phone call, we have a geometric progression of first term, a = 1 and common ratio r = 2. Since the process of phone calls must be repeated 5 times, our last term is 2⁵. So, our geometric progression is 2⁰ + 2¹ + 2² + 2³ + 2⁴ + 2⁵ = 1 + 2¹ + 2² + 2³ + 2⁴ + 2⁵
We now sum the geometric progression
The sum of a geometric progression with r > 1 is
S = a(rⁿ - 1)/(r - 1)
substituting r = 2, a = 1 and n = 6 since we have 6 terms, we have
S = 1(2⁶ - 1)/(2 - 1)
= (64 - 1)/1
= 63
So, we have 63 members in the club.
We could have also found this by summing up individually the terms in the series. We have 1 + 2¹ + 2² + 2³ + 2⁴ + 2⁵ = 1 + 2 + 4 + 8 + 16 + 32 = 63
You found a unit rate that compares dollars earned per hours worked at the coffee shop.Is there another unit rate you could write for this relationship? What does that unit ratemean in the context of the situation? What is the related constant of proportionality?
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete. However, I'll assume the following.
Unit Rate = $10 per 2 hours
Solving further, we have that:
1. Yes, there is another unit rate that can be written.
Unit Rate = $10 per 2 hours
Convert Rate to fraction
[tex]Unit\ Rate = \frac{\$10}{2\ hours}[/tex]
Divide numerator and denominator by 2
[tex]Unit\ Rate = \frac{\$5}{1\ hour}[/tex]
Simplify:
[tex]Unit\ Rate = $5/hour[/tex]
2. The unit rate implies that the earnings is $5 per hour
3. The constant of proportionality
Let y represent the earnings
x represent work hours.
We have:
[tex]y = kx[/tex]
Where k = constant of proportionality
In this case:
[tex]y = 10[/tex]
[tex]x = 2[/tex]
Substitute these values in [tex]y = kx[/tex]
[tex]10 = k * 2[/tex]
[tex]10 = 2k[/tex]
Divide both sides by 2
[tex]5 = k[/tex]
[tex]k = 5[/tex]
Hence: The unit of proportionality is 5

Adam gets a bonus of 30% of £80 Katy gets a bonus of £28
what is the difference between the bonus Adam gets and the bonus Katy gets?
Answer:
£4
Step-by-step explanation:
Adam: 30% of £80
Katy: £28
First, let's fund Adam's bonus. We know that 30% is equal to 0.3. Then, we can multiply £80 by 0.3. This results in £24.
We also know that Katy made £28. Now we need to find the difference.
The difference between Adam and Katy is £4.

Step-by-step explanation:
Trina and Jessie went on a vacation to Hawaii. Trina went scuba diving and reached an elevation of −85.6 meters, which is below sea level. Jessie went hang-gliding and reached an altitude of 87.9 meters, which is above sea level. Who is closer to the surface of the ocean?
Answer:
Step-by-step explanation:
LEt the surface of the ocean be at the zero level i.e at 0metres
If Trina went scuba diving and reached an elevation of −85.6 meters, which is below sea level, the distance between Trina and the sea level will be:
D = 0-(-85.6)
D = 0+85.6
D = 85.6m
If Jessie went hang-gliding and reached an altitude of 87.9 meters, the distance between Jessie and the sea level will be:
D = 87.9-0
D = 87.9m
Since the distance of Trina is less than that of Jessie, this means that Trina is closer to the surface of the ocean

A line with slope -3 passes through the points (5,2) and (9,y). Find y.
plz help!
Answer:
y is 10
Step-by-step explanation:
first take your imformation and put it into the y intercept from.
Which is y=mx+b
so take the cordinates (5,2) and put it into the y-intercept form.
the 5 is x and the 2 is the y, so
2=m*5+b
Then take the slope of -3 and put it in the y-intecept from
2=-3*5+b
then solve for b
2=-3*5+b
2=-15+b
+15 on both sides
17=b
now you know the equation of the line is
y=-3x+17
now plug in your x to find the y of that cordinate
on the line.
y=-3*9+17
solve
y=-3*9+17
y=-27+17
y=10
Another store, Healthy Pets, sells dog food in 50-pound bags for $92.13 per bag. If one bag of food from Pets Galore costs $48.15, how much would Seth save by buying 150 pounds of dog food from Pets Galore instead of from Healthy Pets?
Answer:
$140.91
Step-by-step explanation:
50 pounds = 1 bag
150 pound bags = 150 ÷ 5
3 bags
Another store, Healthy Pets, sells dog food in 50-pound bags for $92.13 per bag.
1 bag = $92.13
3 bags = x
Cross Multiply
x = 3 × $92.13
$276.39
If one bag of food from Pets Galore costs $48.15
1 bag = $48.15
3 bags = x
x = 3 × $48.15
x = $135.48
The amount would Seth save by buying 150 pounds of dog food from Pets Galore instead of from Healthy Pets is
$276.39 - $135.48
= $140.91

Isaiah wants to begin eating a more balanced diet. He thinks he should consume 2,000 calories each day. Recommended the percentage of carbohydrates, fats? And proteins he should consume. Also, tell Isaiah how many grams of each he should consume daily
Answer:
A balance diet is a healthy diet that contains different food intakes.
Step-by-step explanation:
A balance diet may be defined as a diet which contains different varieties of food in certain proportions and quantities so as supply the requirements of the body for proteins, vitamins, calories, minerals and nutrients. It is a healthy diet that helps to maintain and improve the overall health.
For a balance diet, a person needs to take proper amount pf carbohydrates, fats and proteins so that the body gets the required energy in terms of calories for the day.
In the context, Isaiah wishes to consumes 2000 calories of energy in one day for a healthy diet. So according to the United States government recommended diet for the consumption of 2000 calories per day, Isaiah should have 15% of protein, 30% of fat and 55% of carbohydrate. And in terms of gram, she should take 75 gram of protein (300 cal), 67 gram of fat (600 cal) and 275 grams of carbohydrates (1100 cal).
