Barbara sells iced tea for $1.49 per bottle and water for $1.25 per bottle. She wrote an equation to find the number of bottles she needs to sell to earn $100. 1.25x + 1.49 = 100 What error did Barbara make in writing the equation? the number of bottles of water.
Answer:
she didnt write an x next to the 1.49 in her equation. she is writing an equation for how many bottles she is selling but according to her equation she is selling water for 1.25$ times x amount of bottles and selling only one ice tea

Out of the 90 customers at Eva's boutique35 wore a size extra-large. What is the probability that a randomly selected customer wore a size extra-large? Write your answer as a fraction or whole number. P(extra - large) =
Answer: 7/18
Step-by-step explanation:
Number of customers at Eva's boutique = 90
Number of customers who wore a size extra-large = 35
The probability that a randomly selected customer wore a size extra-large will be:
= Number of customers who wore a size extra-large / Number of customers at Eva's boutique
= 35 / 90
= 7/18
Therefore, the probability that a randomly selected customer wore a size extra large is 7/18.

how many perfect squares are there between 2 and 140
Answer:
11
Step-by-step explanation:
4, 9, 16, 25, 36, 49, 64, 81, 100, 121
There are 10 numbers who are perfect squares.
What is Square of a number?When an integer is multiplied by the same integer, the resultant number is known as a square number. For example, when we multiply 5 × 5 = 52, we get 25. Here, 25 is a square number. Square numbers are always positive, they cannot be negative because when a negative number is multiplied by the same negative number, it results in a positive number.
Properties of Square NumbersThe properties of square numbers are listed below which helps to identify them easily.
Square numbers always end with the digits 0, 1, 4, 5, 6, and 9. For example, 25, 49, 81, 100, etc are perfect squares, whereas, 37, 48, 22, etc are not considered to be perfect square numbers.The number of zeros at the end of a square number is always even. This means if a number has an odd number of zeros at the end, then the number is not a square number. For example, 400, 3600 are square numbers, whereas, 10, 250, and 360 are non-square numbers.If a number has 1 or 9 as its last digit, then its square number ends with 1. For example, the square of 9 is 81, and the square of 11 is 121.If a number has 4 or 6 as its last digit, then its square number ends with 6. For example, the square of 4 is 16, and the square of 26 is 676.The square of even numbers is always even, and the square of odd numbers is always odd. For example, the square of 12 is 144, and the square of 13 is 169.Square numbers are always positive because two negative signs multiplied by each other result in a positive sign. For example, (-6)2 = -6 × -6 = 36 . Here, the product is 36 and it is a positive square number.Given:
2 and 140
Now, the perfect squares are:
√4=2
√9=3
√16 =4
√25=5
√36=6
√49=7
√64=8
√81=9
√100=10
√121=11

Write the equation of the line that passes through (−3,1) and (2,−1) in slope-intercept form
Answer:
[tex]y=-\frac{2}{5}x-\frac{1}{5}[/tex]
Step-by-step explanation:
The equation of a line is y = mx + b
Where:
m is the slopeb is the y-interceptFirst, let's find what m is, the slope of the line.
Let's call the first point you gave, (-3,1), point #1, so the x and y numbers given will be called x1 and y1.
Also, let's call the second point you gave, (2,-1), point #2, so the x and y numbers here will be called x2 and y2.
Now, just plug the numbers into the formula for m above, like this:
[tex]m = -\frac{2}{5}[/tex]
So, we have the first piece to finding the equation of this line, and we can fill it into y=mx+b like this:
[tex]y=-\frac{2}{5}x + b[/tex]
Now, what about b, the y-intercept?
To find b, think about what your (x,y) points mean:
(-3,1). When x of the line is -3, y of the line must be 1. (2,-1). When x of the line is 2, y of the line must be -1.Now, look at our line's equation so far: [tex]y=-\frac{2}{5}x + b[/tex]. [tex]b[/tex] is what we want, the -[tex]-\frac{2}{5}[/tex] is already set and x and y are just two 'free variables' sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the two points (-3,1) and (2,-1).
So, why not plug in for x and y from one of our (x,y) points that we know the line passes through? This will allow us to solve for b for the particular line that passes through the two points you gave!
You can use either (x,y) point you want. The answer will be the same:
(-3,1). y = mx + b or [tex]1=-\frac{2}{5} * -3 + b[/tex], or solving for b: [tex]b = 1-(-\frac{2}{5})(-3)[/tex].[tex]b = -\frac{1}{5}[/tex]. (2,-1). y = mx + b or [tex]-1=-\frac{2}{5} * 2 + b[/tex], or solving for b: [tex]b = 1-(-\frac{2}{5})(2)[/tex]. [tex]b = -\frac{1}{5}[/tex].See! In both cases, we got the same value for b. And this completes our problem.
The equation of the line that passes through the points (-3,1) and (2,-1) is [tex]y=-\frac{2}{5}x-\frac{1}{5}[/tex]

Mr. Kumar is getting his house renovated. 1/5 th of the work has been completed in 2 months. How much time will it take for the entire work to be completed?
Answer:
10 months
Step-by-step explanation:
If it takes 2 months to do 1/5th, it will take 4 months to do 2/5, 6 months to do 3/5, 8 months to do 4/5, and 10 months to do 5/5 or in other words the whole thing.
The remaining work will take 8 month.
What is Algebra?Algebra is the branch of mathematics that represents problems in the form of mathematical expressions. It involves variables like x, y, z, and mathematical operations like addition, subtraction, multiplication, and division to form a meaningful mathematical expression.
Given:
As, 1/5 th of the work has been completed in 2 months.
let the total time taken to complete the work is 'x' month.
1/5 * x = 2
x= 5*2
x=10 month
Hence, remaining work will take (10 - 2) = 8 month.

A rectangle has vertices at: A(0, 0), B(0, 9), C(4, 9), D(4, 0) What is the perimeter of the rectangle?
Answer:
Rectangle Perimeter = 26
Step-by-step explanation:
Rectangle ABCD , Length = parallel horizontal sides are AB & CD, Breadth = parallel vertical sides = BC & AD
AB segment joining A (0,0) - B (0,9) = 9 units. CD joining C (4, 9) & D (4,0) = 9 units. So, Length = 9 units
BC segment joining B (0,9) - C (4,9) = 4 units. AD joining A (0,0) - D (4,0) = 4 units. So, Breadth = 4 units
Perimeter of rectangle = 2 (Length + Breadth)
= 2 (9 + 4)
= 13 x 2 = 26

So first things First You are going to put a Dot on 2 on the y-axes, then the fraction is you Slope- Rise over- run
so you're going up 4 and over 5
Hope this helps !
Answer:
See attachment :)
Step-by-step explanation:
The given equation is in slope-intercept form, which lists the slope and the y-intercept of the line.
Slope-intercept form is [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept. The y-intercept, 2, is a point on the y-axis where the line intersects with the axis. So, we can graph the given intercept on the y-axis, (0,2).
The slope, [tex]m[/tex], is [tex]\frac{4}{5}[/tex]. The slope is the rise of the line over the run, or [tex]\frac{rise}{run}[/tex]. For this equation, then, we rise 4 units and run 5.
We'll start from the y-intercept, a point we know will be on our line. From this point, move up 4 units, and right 5. A negative slope would run to the left, but this is a positive line, so the run will go to the left. Now, we are on the point (5,6). From this point, we can repeat this [tex]\frac{rise}{run}[/tex].
A few of the following points are (10,10), (14,15), and (18,20). Now, draw a line connecting these points. This line is a graph of our equation.
I've attached a photo of the graphed line.

.Find the area of the figure
Answer:
Area of the figure = 171 in²
Step-by-step explanation:
Composite figure given in the picture comprises of three figures, two right triangles and one rectangle.
Area of the composite figure = Area of two right triangles + Area of the rectangle at the center
Area of one right triangle = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(12)(9)[/tex]
= 54 in²
Area of the rectangle = Length × Width
= 7 × 9
= 63 in²
Area of the composite figure = 2(54) + 63
= 108 + 63
= 171 in²
