PLEASE ANSWER ASAP Michael read 14 books in 26 months. At the same rate, about how many books can he read in 48 months?
Answer:
Well, lets break this down.
If you try to add 26 + 26 it would be 52, which is above 48.
So, we have to find how many books he can read in one month.
All we have to do, is divide!
14 = dividend
26 = divisor
Step 1:
Start by setting it up with the divisor 26 on the left side and the dividend 14 on the right side like this:
26⟌14 Then do the rest, ill wait.
once you have a answer, that is how much he reads a month.
now multiply by 48.
A rectangle that is 2 inches by 3 inches has been scaled by a factor of 7.
1. What are the side lengths of the scaled copy?
2. Suppose you want to scale the copy back to it's original size. What scale factor should you use?
Answer:
To get the new scaled copy length and width just multiply by seven (2x7 & 3x7)
New length would be 14 because it's "seven times" the original size
New width would be 21
Step-by-step explanation:
1.) 14 and 21
2.) 14 divided by 7 will give you 2
and 21 divided by 7 will give you 3
The answer for question 2 would be to divide your new answers (21 and 14) by the scaled factor of 7.

-8x + 40 greater than -16
Answer:
x > 7
Step-by-step explanation:
First, you start off with :
-8x + 40 > -16
Then you subtract 40 on both sides.
You get -8x > -56.
Next, you divide -8 on both sides. Cancel out the -8/-8.
After dividing, you have x > 7
Therefore the answer is x > 7!

X+Y=4.25
16.90X+4Y=36.35
What are the values of X and Y
Answer:
Y = 2.75X = 1.5Step-by-step explanation:
X+Y=4.25
16.90X+4Y=36.35
That means that;
X = 4.25 - Y
Substituting X into the second equation is;
16.90 * (4.25 - Y) + 4Y = 36.35
71.825 - 16.90Y + 4Y = 36.35
71.825 - 12.90Y = 36.35
71.825 - 36.35 = 12.90Y
Y = 35.475/12.90
Y = 2.75
X = 4.25 - Y
= 4.25 - 2.75
= 1.5
From the computation done, the value of X is 2.75 and Y is 1.5.
The following information can be depicted:
X + Y=4.25 .... i
16.90X + 4Y=36.35 ..... ii
From equation i
X = 4.25 - Y
We'll substitute X into the second equation and this will be:
16.90(4.25 - Y) + 4Y = 36.35
71.825 - 16.90Y + 4Y = 36.35
71.825 - 12.90Y = 36.35
Collect life terms
71.825 - 36.35 = 12.90Y
Y = 35.475/12.90
Y = 2.75
Since X = 4.25 - Y
X = 4.25 - 2.75
X = 1.5

Yuppietown has two food stores, La Boulangerie, which sells bread, and La Fromagerie, which sells cheese. It costs $1 to make a loaf of bread and $2 to make a pound of cheese. If La Boulangerie’s price is P1 dollars per loaf of bread and La Fromagerie’s price is P2 dollars per pound of cheese, their respective weekly sales, Q1 thousand loaves of bread and Q2 thousand pounds of cheese, are given by the following equations: Q1 = 14 − P1 − 0.5P2 and Q2 = 19 − 0.5P1 − P2. (a) For each store, write its profit as a function of P1 and P2. Then find their best-response
Answer:
Step-by-step explanation:
Given that:
Q1 = 14 − P1 − 0.5P2
Q2 = 19 − 0.5P1 − P2
Recall that:
Profit = Total revenue - Total cost
π₁ = P₁Q₁ MCQ₁
π₁ = P₁(14 - P₁ - 0.5P₂) - Q₁
π₁ = 14P₁- P₁² - 0.5 P₁P₂ - 14 + P₁ + 0.5P₂
π₁ = 15P₁ - P₁² - 0.5P₁P₂ + 0.5P₂ - 14
π₂ = P₂ (19 - 0.5P₁ - P₂) - 2(19 - 0.5P₁ - P₂)
π₂ = 19P₁ - 0.5P₁P₂ - P₂² - 38 + P₁ + 2P₂
π₂ = 21P₂ - P₂² - 0.5 P₁ P₂ + P₁ - 38
The profit functions are π₁ & π₂
The best-response function from firm 1 is;
π₁ = 15P₁ - P₁² - 0.5P₁P₂ + 0.5P₂ - 14
[tex]\mathbf{\dfrac{\partial \pi_1}{\partial P_1}= 15 - 2P_1 -0.5P_2 =0}[/tex]
[tex]\mathbf{P_1= \dfrac{15-0.5P_2}{2}}[/tex]
The best-response function from firm 2 is;
π₂ = 21P₂ - P₂² - 0.5 P₁ P₂ + P₁ - 38
[tex]\mathbf{\dfrac{\partial \pi_2}{\partial P_2}= 21 - 2P_2 -0.5P_1 =0}[/tex]
[tex]\mathbf{P_2= \dfrac{21-0.5P_1}{2}}[/tex]
Here we must find the profit for each one of the two stores.
For La Boulangerie the profit is: (14 − P1 − 0.5*P2)*(P1 - $1)For La Fromagerie the profit is: (19 − 0.5P1 − P2)*(P2 - $2).Remember that profit is defined as the difference between the revenue and the cost.
For La Boulangerie we know that they sell Q1 thousand loaves. Each loaf costs $1. Each loaf is sold by P1
Then the profit is just:
P = Q1*(P1 - $1) = (14 − P1 − 0.5*P2)*(P1 - $1)
Which is already written only in terms of P1 and P2.
Similarly, for the other store we will get the profit:
P' = Q2*(P2 - $2) = (19 − 0.5P1 − P2)*(P2 - $2)
Now we must get their best response, which is given by deriving it with respect to the price and making it equal to zero:
For the first store we have:
dP/dP1 = $1 + 14 - 0.52*P2 - 2*P1 = 0
Now we solve it for P1:
P1 = ($1 + 14 - 0.52*P2)/2
Similarly, for the other store we have:
dP'/dP2 = 19 - 0.5*P1 - 2*P2 + $2 = 0
Solving it for P2 it gives:
P2 = (19 - 0.5*P1 + $2)/2

Show your work
PLEASE HELP DUE TODAY THANK YOU SO MUCH.
.
Answer:
63 men said no.
Step-by-step explanation
3/5 * 2/2 = 6/10, 6/10 - 3/10 (women) = 3/10 meaning 7/10 men said no. 90*1.7 = 153, 153-90=63
Answer:
30%. Remember the question is what percentage?
Step-by-step explanation:
Given Informations:
Men = 90
Women = 60
Total number (men + women) = 150. ...... (1)
For Yes Members,
3/5 of the people said YES.
3/5 of 150 = 90 ....... (2)
This means that out of 150, 90 people said YES.
However, we dont know what ratio are men or women all we can deduce is that 90 said YES.
From the question, 3/10 are women that said YES.
Meaning 3/10 of 90 are women = 27. .. (3)
27 women said YES therefore
90 -27 = 63 Men said YES.
FOR NO Members,
If 90 out of 150 said yes, then 60 said NO.
However, we dont know the ratio of Men and Women that said NO. What we can do is to solve it from the known to the unknown.
For Men,
The total number is 90.
63 said YES, therefore (90 - 63 ) definitely said NO.
= 27 Men said NO (4)
For Women,
The total number of women is 60
27 said YES, Therefore (60 - 27) said NO
= 33 women said NO. ( 5)
The question is what percentage of Men said NO?
Percentage =
number of men that said NO / The total number of Men * 100
= 27/90 * 100
=30%
To Prove the Answer
If you agree with Eq 2, which says 90 people said yes. Therefore, (150 -90) = 60 said NO.
Remeber the 60 is inclusive of Men and Women.
Let's see, if we will get 60 when we add the number of men and women we got that said NO.
Add the value in Eq 4 + Eq 5.
27 + 33 = 60.

write an equation to solve for x 3x + 21 6x-60 will mark brainiest
Answer:
3x + 21 = 6x - 60Step-by-step explanation:
parallel angles are equal
3x + 21 = 6x - 60
combine similar terms:
3x - 6x = -60 - 21
-3x = -81
x = 81/3
x = 27
now, plugin the value of x=27 back into the equation to get the angle:
= 3x + 21
= 3(27) + 21
= 102
= 6x - 60
= 6(27) - 60
= 102
as you noticed, both values are equal 102 = 102 because its a parallel angles
so the equation is 3x + 21 = 6x - 60

Assume a recent sociological report states that university students drink 4.10 alcoholic drinks per week on average, with a standard deviation of 1.9101. Suppose Jason, a policy manager at a local university, decides to take a random sample of 125 university students to survey them about their drinking habits. Determine the mean and standard deviation of the sampling distribution of the sample mean alcohol consumption. Provide your answer with precision to two decimal places.
Answer:
4.10
0.17
Step-by-step explanation:
From the question, we know that
A recent sociological report stated that university students drink 4.10 alcoholic drinks per week on average, with a standard deviation of 1.9101.
Also, we're tasked with finding the mean and standard deviation of the sampling distribution of the sample mean alcohol consumption.
To find the mean of the sampling distribution, we take the sample mean of the same of that university students as a direct substitute. This then means that the mean of the sampling distribution of the sample mean alcohol consumption is 4.10 alcoholic drinks per week on average.
On the other hand, the standard deviation of the sampling distribution of the sample mean alcohol consumption is taken to be the division of the standard deviation of the sample mean. Mathematically, we have
Standard Deviation, S = 1.9101 / √125
Standard Deviation, S = 1.9101 / 11.18
Standard Deviation, S = 0.17
Therefore, the Standard Deviation is 0.17
Answer:
The values are
[tex]\mu_{\= x } = \mu = 4.10[/tex]
And
[tex]\sigma _{\= x} = 0.38202[/tex]
Step-by-step explanation:
The population mean is [tex]\mu = 4.10[/tex]
The standard deviation is [tex]\sigma = 1.9101[/tex]
The sample size is n = 125 students
Generally the mean of the sampling distribution of the sample mean is equivalent to the population mean
i.e [tex]\mu_{\= x } = \mu = 4.10[/tex]
Generally the standard deviation of the sampling distribution of the sample mean alcohol consumption is mathematically represented as
[tex]\sigma _{\= x} = \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]\sigma _{\= x} = \frac{1.9101 }{\sqrt{125} }[/tex]
=> [tex]\sigma _{\= x} = 0.38202[/tex]

Multiply the sides of the equation by ( b + 5 ) :
[tex]7 =2 \times (b + 5)[/tex]
[tex]7 = 2b + 10[/tex]
Subtract the sides of the equation minus 10 :
[tex]7 - 10 = 2b[/tex]
[tex] - 3 = 2b[/tex]
Divided the sides of the equation by 2 :
[tex]b = - \frac{3}{2} \\ [/tex]
