Each of four circles has a radius of 4 inches. A larger circle has an area equal to the total area of the four smaller circles. What is the length of the radius, in inches, of the larger circle?
The radius of the larger circle is 8 inches
What is a circle?A circle is a round plane shape, whose circumference consists of points equidistant from a fixed point.
To calculate the radius of the larger circle, we use the formula below.
Formula:
A = 4A'............. Equation 1Where:
A = Area of the larger circleA' = Area of the smaller circle.But,
A = πR².............. Equation 2A' = πr²........... Equation 3Where:
R = Radius of the larger circler = radius of the smaller circle.Substitute equations 2 and 3 into equation 1
πR² = 4πr²R² = 4r²R = 2r .............. Equation 4Given:
r = 4 inchesSubstitute this value into equation 4
R = 2×4R = 8 inchesHence, The radius of the larger circle is 8 inches.

Using linear function concepts, it is found that the correct statements are given by:
The value of 15000 represents the start-up cost.The company spends $57,000 to manufacture 2000 headbands.What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and it can also be interpreted as the initial value.In this problem, the cost of manufacturing H headbands is given by:
[tex]C(h) = 21h + 15000[/tex]
The y-intercept is of 15000, which means that the value of 15000 represents the start-up cost.
Manufacturing 2000 headbands, the cost is of:

1. Mike has four cards numbered one to four. He draws one card and records the number. Calculate the probability that the result will be:
A a multiple of three
B a multiple of two
C a factor of three
Answer:
A) [tex]\frac{1}{4}[/tex]
B)[tex]\frac{2}{4}[/tex]
C)[tex]\frac{2}{4}[/tex]
Step-by-step explanation
sample space (S) = {1,2,3,4}
n(S) = 4
multiples of three (a) = {3}
n(a) = 1
probability of a = [tex]\frac{n(a)}{n(S)}[/tex]
= [tex]\frac{1}{3}[/tex]
multiples of two(b) = {2,4}
n(b) = 2
probability of b = [tex]\frac{n(b)}{n(S)}[/tex]
= [tex]\frac{2}{4}[/tex]
factors of three(c) = {1,3}
n(c) = 2
probability of c = [tex]\frac{n(c)}{n(S)}[/tex]

Answer: 40/11 hours
Step-by-step explanation:
Since y represents the amount of time the car goes at 35 miles per hour, and it is given that the car spends no time at 35 miles per hour, y = 0.
We can plug y into the equation given to find x, which would be the time travelled at 55 miles per hour, or the total time in this case.
55x + 35*0 = 200
55x = 200
x = 200/55

What is a probability distribution?For a particular data generation process, a probability distribution represents the predicted outcomes of various values. The mean, standard deviation, skewness, and kurtosis are all features of probability distributions, which are characterized by the mean, standard deviation, skewness, and kurtosis.
The mean of the probability distribution is determined by the given formula,

Give three pros and cons of getting a pug, and the same for a poodle.
Answer:
Step-by-step explanation:
pugs;
pros= Pugs are small in size and thus, making them suitable for small-sized rooms or apartments. Pugs have a friendly and lapdog temperament, get along well with most people and pets. Pugs are low to medium-shed breeds, which implies you are less likely going to be troubled with shedding.
cons= Pugs are prone to various throats, ears, eyes, folds, facial infections, and breathing troubles; hence they will require regular health check-ups. Pug dogs are not highly trainable – it will be difficult to train a pug to do not-so-easy activities even if you hire a professional.
poodle;
pros=They don't shed. Poodles have long hair, instead of fur so they do not shed. ...
They're easy to train. The poodle's intelligence and eagerness to please make them easy to train. ...
They're good with children or other dogs. ...
They make great service dogs or therapy dogs.
cons= Their hair requires some serious maintenance. Because poodles can grow their hair long, they require a lot more maintenance than breeds with short, flat coats. ...
They require a lot of mental stimulation. ...
They can be emotionally sensitive.
Answer: brainliest please!
Pros of a Pug
! Pugs are small in size and thus, making adaptable small-sized rooms or apartments.
! Pugs have a friendly temperament and get along well with other people/pets.
! Pugs are low to medium-shed breeds which mean you are less likely going to be troubled with shedding.
! Can take simple commands without hiring a professional trainer/ train on your own
Cons of a Pug
! Gains weight easily and lack of daily exercises like a walk or run can easily have them gain weight and affect their health.
! Pug dogs are not highly trainable ~ can do simple tricks like:
sit, stand, run, fetch but not complicated ones
! Health risks ~ Pugs are prone to throat, ears, eyes, facial infections, and breathing troubles :; hence they will require regular health check-ups.

Pros of Poodle
! They don’t shed. Poodles have long hair, instead of fur so they do not shed.
! super easy to train compared to pugs and easily learn hard tricks and so.
! They're good with children or other dogs
! They make great service dogs or therapy dogs
Cons of Poodle
! Their hair requires some serious maintenance
! They can be emotionally sensitive
! IMPORTANT - They require a lot of mental stimulation
These pups have trained to live a luxurious lifestyle they’re rarely content to live as lap dogs. They will use their intelligence for less desired behaviors like digging, chewing, or excessive barking. If your lifestyle doesn’t allow you to provide ample mental stimulation for your dog, it might be worth considering another breed.

Ryan walked
small dogs.
Answer:
He walked 5 small dogs and 3 large dogs.
Step-by-step explanation:
We'll represent the number of small dogs Ryan walked 'x,' and the number of large dogs Ryan walked '8-x.'
49 = 5x + 8(8-x)
x=5
8-5=3
Therefore, Ryan walked 5 small dogs and 3 large dogs.

Solve the following system of equations.
Answer:
x= 0, y= -15
Step-by-step explanation:
Start by labelling the 2 given equations.
y= -2x -15 -----(1)
y= -15 +3x
y= 3x -15 -----(2)
Substitute (1) into (2):
-2x -15= 3x -15
3x +2x= -15 +15
5x= 0
Divide both sides by 5;
x= 0
Substitute x= 0 into (2):
y= 3(0) -15
y= -15
Answer:
Let eqn 1 be y = -2x -15
and Eqn2 be y-3x =-15
Substitute Eqn 1 into Eqn 2
where -2x-15-3x = -15
-5x = 0
X is 0
from Eqn1 the value of y Will be
-2(0) - 15
Value of y is -15
Therefore (X,y) = (0, -15)
