Answer:
[tex]23=0.50r+22[/tex]
Step-by-step explanation:
y=total amount of money
b=cost of admission
m=cost per ride
r= amount of rides
How to solve:
Step 1: Set up the equation in [tex]y=mx+b[/tex] format.
[tex]23=22+0.50r[/tex]
Step 2: Subtract 22 from both sides of the equation.
[tex]23-22=22+0.50r-22[/tex]
Step 3: Divide both sides by 0.50
[tex]\frac{1}{0.50} =\frac{0.50r}{0.50}[/tex]
Step 4: You are left with your answer.
[tex]r=2[/tex]

She turns around and begins to walk back home, but when she is halfway home (from where she turned around), she finds her phone. She turns back around to walk to Jenny's and arrives there at 10 am. How far apart are Cindy's house and Jenny's house?
Hint: Draw a diagram!
Answer:

Step-by-step explanation:
don't forget your phone so anyon doesn't ever have to do this
Cindy's house and Jenny's house are 1.33 miles distant from each other.
What is speed?Speed is defined as the rate at which an object is moving (covering a particular distance). It is a scalar quantity as it defines only the magnitude and not direction.
The SI derived unit for speed is meter per second (m/s).
Given,
Cindy leaves house at 9 am and reaches to jenny house at 10 am
Let the distance between Cindy and Jenny house is x
First, Cindy walks half way to jenny house = x/2
then Cindy take U-turn and walks half way to home = x/4
again Cindy take U-turn and reaches jenny house = 3x/4
Total distance walked by Cindy = x/2 + x/4+ 3x/4
= x/2 + x
= 3x/2
Speed of jenny is 2 miles per hour
She walks 3x/2 distance and reaches Jenny house in one hour
⇒ 3x/2 = 2
⇒ 3x = 4
⇒ x = 4/3
⇒ x = 1.33 miles
Hence, distance between Cindy's and jenny's house is 1.33 miles.

A bacteria that starts with 3 cells increases by 15% every hour.
Write an exponential growth equation that models the situation
How many bacteria cells will there be in 13 hours?
Answer:
Step-by-step explanation:
In order to determine the equation, consider that any exponential growth equation can be written as follow:
[tex]f(t)=A(1+r)^t[/tex]
where,
f(t): amount of bacteria after t hours
A: initial amount of bacteria = 3
r: growth rate in decimal form = 0.15 (15%)
t: time in hours
By replacing the previous values into the expression for f(t) you get;
[tex]f(t)=3(1+0.15)^t\\f(t)=3(1.15)^t[/tex]
Hence, the answer is f(t) = 3(1.15)^t
Now, replace t = 13 to determine the amount of bacteria after 13 hours:
[tex]f(13)=3(1.15)^13\\f(13)=18.46[/tex]
Hence, after 13 hours there are approximately 18 bacteria

Answer: 840
Step-by-step explanation: 50% is half. All I did was add 420 two time since 420 is half of what this person has to spend.
Answer:
the answer should be 210 dollars because first of all remember that when we are dealing with this problems of percents we need to divide first the percent which is 50% by 100 and you will get 0.50 so then you multiplied it.
0.50 times 420= 210

Step 1: Find area of inner square = 4 ft × 12 ft = 48ft2
Step 2: Find area of outer shape =

Step 3: Area of shaded region = area of outer shape – area of inner square
= 36 ft2 – 48 ft2
= 12 ft2
In the game 'rock, paper, scissors', both players make a fist with one hand. On the count of three, the players make either a rock (by keeping their hand in a fist), a sheet of paper (by holding their hand out flat), or a pair of scissors (by sticking out their first two fingers).
If both players make the same thing, it's a tie. If a rock and scissors are played, the rock wins. If scissors and paper are played, the scissors win. If paper and a rock are played, the paper wins.
a) Play at least 20 games of 'rock, paper, scissors' with a friend. Record the results as you go - write down who won, and what with.
b) After you've finished playing, organise your results into a table and use this to estimate some probabilities. Who was most likely to win? Were either of you more likely to play a certain object each time? Could you use this information to help you win more games next time?
If this is for a school assignment, not sure how someone else would record themselves playing rock paper scissors.
