At the local food stand, the vendor sells small drinks for $1.25 each and large drinks for $2.50 each. They sold 155 drinks today and made $265. How many small drinks and how many large drinks did they sell?
Answer:
98 small drinks and 57 large drinks.
Explanation:
Let's call x the number of small drinks and y the number of large drinks.
If they sold 155 drinks, we can write the following equation:
x + y = 155
In the same way, they made $265, so
1.25x + 2.50y = 265
Because each small drink cost $1.25 and each large drink cost $2.50.
Now, we can have the following system of equations
x + y = 155
1.25x + 2.50y = 265
Solving the firs equation for y, we get:
x + y - x = 155 - x
y = 155 - x
Replacing this on the second equation:
1.25x + 2.50y = 265
1.25x + 2.50(155 - x) = 265
Then, solving for x, we ge:
1.25x + 2.50(155) - 2.50(x) = 265
1.25x + 387.5 - 2.50x = 265
-1.25x + 387.5 = 265
-1.25x + 387.5 - 387.5 = 265 - 387.5
-1.25x = -122.5
-1.25x/(-1.25) = -122.5/(-1.25)
x = 98
Finally, we can find the value of y replacing x = 98
y = 155 - x
y = 155 - 98
y = 57
Therefore, they sell 98 small drinks and 57 large drinks.

1) Considering a Normal Distribution, then we can write out the following:
[tex]P(X>5710)=P(X-\mu>5710-6000)=P(\frac{X-\mu}{\sigma}>\frac{5710-6000}{1000})[/tex]Note that we're dealing with probabilities.
2) Let's find out the Z-score resorting to a table, we get:
[tex]Z=\frac{x-\mu}{\sigma}=\frac{5710-6000}{1000}=-0.29[/tex]2.2) So we can infer from 1 and 2:
[tex]P(X>5710)=P(Z>-0.29)=0.6141[/tex]Notice that this distribution refers to 120 families

The sample standard deviation of the population with confidence interval of 95% is 13.57
What is standard deviation?Standard deviation gives a value that measures how much the given value differ from the mean.
How to find the sample standard deviationGiven data form the question
95% confidence interval
population mean of a normally distributed variable is 17.3 to 24.5
population was 76
Definition of variables
confidence interval = CI = 95%
mean = X = 17.3 to 24.5
taking the average, X = 21.45

What is the distance from Point B (-1, 11) to line y = -1/3x - 6?
Answer in simplest radical form
The distance from Point B (-1, 11) to line y = (-1 ÷ 3x) - 6 is 15.811.
The distance from the point B(-1 , 11) to the line y= (-1 ÷ 3x) - 6 is given by the distance formula d = (|Ax1 + By1 + C|) ÷ (√(A² + B²)).
Comparing the equation y= (-1 ÷ 3x) - 6 with the standard forms Ax + By+ C = 0.
It is clear that the coefficient of x, A = -1 ÷ 3.
The coefficient of y, B = -1. The constant C = -6 and the points x1 = -1 and y1 = 11.
Substituting these data in the equation the distance d = (|(-1÷3)×(-1)+ (-1)×11 + (-6)|) ÷ √((-1 ÷ 3)² + (-1)² ) solving the equation the distance d becomes,
d = 15.811.

The inverse function of a function f in mathematics exists a function that reverses the operation of f. The number of problems completed as input and returns the number of minutes worked exists m(p) = 6p - 54.
What is meant by inverse function?An inverse in mathematics is a function that "undoes" another function. In other words, if f(x) yields y, then y entered into the inverse of f yields the output x.
Given: P(m) = (m/6) + 9
Determine the inverse function
P(m) = (m/6) + 9
Represent P(m) as P
P = (m/6) + 9
Swap the positions of P and m
m = (p/6) + 9
We are to make p the subject.
Subtract 9 from both sides, then we get
m - 9 = (p/6) + 9 - 9
m - 9 = (p/6)

Answer:
y = -2x + 2
Step-by-step explanation:
so to find the slope of the graph we must do (rise)/(run)
when we see the graph we see that when it goes DOWN 2 it also goes RIGHT 1
RISE is up or down
RUN is left or right
since it is down it is negative
so
-2 / 1
that is just -2
that is the slope
the equation for slope intercept is y = mx + b where m is the slope and b is the y intercept
so far it is y = -2x + b
the y intercept is where it crosses the y axis
that point is 2 based off of the graph
so
y = -2x + 2 is your answer

What are the properties of parallel lines?If you extend a set of lines indefinitely, they will remain parallel and never cross each other even though they are on the same plane. The symbol || represents the collection of parallel lines. All parallel lines are always equally spaced apart. Investigate the characteristics of parallel lines.
When two lines in a plane are stretched infinitely in both directions and do not cross, they are said to be parallel.
To solve the given question we know,
angle 1= angle 2 and lines RV // TS
angle 4= angle 3(interior angles on parallel lines are equal)
angle 1=angle 4 (vertically opposite angles are equal )
angle 1= angle 3 (angle 4=angle 1)
angle 4=angle 2( angle 1=angle 4)
Now we can see that the sum of base angles of the diagram will be 180 because
180-angle 3= angle STV
angle 4=angleSTV+180 (angle 3=angle4)

Randy has $12 which he decides to put into his savings account. Every week Randy does chores to earn a $6 allowance which he continues to save and put into his savings account.Like Randy, Becky decides to be more responsible with her money and also save her money. Right now she owes her parents $8. Becky also earns $7 a week for doing chores, If both Randy and Becky save up beginning today whose savings account would reach $50first?A. RandyB. BeckyC. They would reach $50 at the same time.D. There is not enough given information to determine who will save up $50 first
Randy's initial money = $12
Randy's earnings per week = $6
Becky's initial money = -$6 (she owes )
Becky's earnings per week = $7
Number of weeks: x
The equation for each:
• Randy:
50 = 12 + 6x
• Becky:
50 = -6 + 7x
Solve each for x:
Randy:
50= 12 + 6x
50-12 = 6x
38 = 6x
38/6=x
x= 6.3
Becky:
50= -8 + 7x
50+8 =7x
58=7x
58/7=x
x= 8.28
Randy will take 6.33 weeks and Becky 8.28 weeks.
Answer:
A. Randy
I need whit math thats all(x-2) +(x+6)
To simplify the expression (x-2) +(x+6), you have to follow these steps:
1.Get rid of the parentheses:
(x-2) +(x+6)
x -2 + x + 6
2. Combine like terms:
x + x - 2 + 6
2x + 4
So the answer is 2x + 4
crate A exerts a force of 8320N and a pressure of 64N/cm2. crate B exerts a force of 9860N and a pressure of 29N/cm2. find the difference between the base areas of the crates in cm2
Answer:
difference in base areas = 210 cm²
Step-by-step explanation:
In order to calculate the difference in the base areas of the crates, we first need to find the base area of each crate.
To calculate the base area, we can use the formula for pressure and rearrange it to make area the subject:
[tex]\boxed{Pressure = \frac{Force}{Area}}[/tex]
⇒ [tex]Area = \frac{Force}{Pressure}[/tex]
Therefore:
•Base area of crate A = [tex]\mathrm{\frac{8320 \ N}{64 \ N/cm^2}}[/tex]
= 130 cm²
• Base area of crate B = [tex]\mathrm{\frac{9860 \ N}{29 \ N/cm^2}}[/tex]
= 340 cm²
Now that we know the base areas of each crate, we can easily calculate the difference between them:
difference = 340 cm² - 130cm²
= 210 cm²
Rewrite the expression (17x3 – 12x2 + 6x - 4)/(x – 1) in the form q(x) + r(x)/b(x) where q(x) = quotient, r(x) = remainder, and b(x) = divisor, using the synthetic division method.
Given that
The equation is
[tex]\frac{17x^3-12x^2+6x-4}{x-1}[/tex]and we have to convert it into the form of
[tex]\begin{gathered} q(x)+\frac{r(x)}{b(x)} \\ where\text{ q\lparen x\rparen is quotient, r\lparen x\rparen is remainder, and b\lparen x\rparen is divisor.} \end{gathered}[/tex]
