Answer:
800 20 1
50| | | |
4 | | | |
pretty much a rectangle with 800 20 1 at the top
50 4 on the side
and split the numbers in the box - i tried to recreate it as much as possible
oh then in each little box you have to multiply the numbers so
50 x 800 = 40,000 in the box
50 x 20 = 1,000 in the next box
50 x 1 = 50 in the next box
4 x 800 = 3,200
4 x 20 = 80
4 x 1 = 4
then you add all of them which would be 44,334

Answer:
7 1/12 cups of flour

Two friends go out to eat and order the same meal. They pay a 6% sales tax and a 20% tip on their meals. The total bill, including tax and tip, is $27.72. How much did each meal cost before tax and tip? (Assume that the friends pay a tip on the cost of the meals only.) IF CORRECT I WILL GIVE BRAINLIEST!!
Sales tax and tip will increase the price of an item.
The cost of each meal is: $10.89
Let the cost of both meals be x.
A 20% tip means that, the current price is:
[tex]Price = x \times (1 + 20\%)[/tex]
A 6% sales tax on the meal means that, the current price is:
[tex]Price = x \times (1 + 20\%) \times (1 + 6\%)[/tex]
So, we have:
[tex]Price = x \times (1 + 0.20) \times (1 + 0.06)[/tex]
[tex]Price = x \times (1.20) \times (1.06)[/tex]
[tex]Price = x \times 1.272[/tex]
The amount paid is $27.72
So, the equation becomes
[tex]27.72= x \times 1.272[/tex]
Make x the subject
[tex]x = \frac{27.72}{1.272}[/tex]
[tex]x = 21.78[/tex]
So, the cost of each meal is:
[tex]Each= \frac{21.78}{2}[/tex]
[tex]Each= 10.89[/tex]
Hence, the cost of each meal is: $10.89

The rectangle below has sides measuring 6cm and 5 cm. What is the area of this rectangle
Answer:30 cm
Step-by-step explanation:
Area is found by two side lengths multiplied together, the two side lengths in the problem are 5cm and 6cm, 5 times 6 is 30, (plus add the measurement) which is 30 cm. :))
The area of the rectangle which has sides that measures 6cm and 5cm is 30 cm²
How to calculate the area of the rectangle?The rectangle has two sides that measures 6cm and 5cm respectively
The formula for calculating the area of a rectangle is length multiplied by width
The area of the rectangle can be calculated as follows
= 6 × 5
= 30 cm²
Hence the area of the rectangle is 30 cm²

Suppose a scatter plot indicates that there is a positive linear association between two quantitative variables. Which of these statements MUST
be correct about the line of best fit for the data in the scatter plot?
Answer:
As the x increases, the y increases. The line will have a positive slope.
A Scatter Plot has points that show the relationship between two sets of data and the points are plotted on horizontal and vertical axes.
The statement about the line of best fit for the data in the scatter plot is the line must have a positive slope.
What is a scatter plot?A Scatter Plot has points that show the relationship between two sets of data. The points are plotted on horizontal and vertical axes.
We have,
A positive linear association between two quantities variables.
Positive linear association means:
If one variable increases as the other variable increases.
Negative association means:
If one variable increases and the other variable decreases.
No association means:
There is no relationship between the variables.
Thus the statement about the line of best fit for the data in the scatter plot is the line must have a positive slope.

Is x-10 a factor of f(x)=5x^3+60x^2+109x+90
Answer:
No
Step-by-step explanation:
Given values are
f(x) = 5x^3+60x^2+109x+90
x = -10.
Given Polynomial is 5x^3+60x^2+109x+90 .
= (90)+(5.x^3)+(60.x^2)+(109.x)
By putting x = (-10) we can rewrite it as
= (90)+(5.(-10)^3)+(60.(-10)^2)+(109.(-10))
= (90)+(-5000)+(6000)+(-1090)
= 0
The remainder of given polynomial is 0.

Mr. Alcazar bakes cookies in batches of 60 and batches of 90. If he bakes 6 batches of 60 cookies, how many cookies does he bake?
Answer:
Mr. Alcazar baked 810 cookies.
Step-by-step explanation:
Given that Mr. Alcazar bakes 6 batches of 60 cookies and five batches of 90 cookies, to determine the amount of cookies that he cook, the following calculation must be performed:
(6 x 60) + (5 x 90) = X
360 + 450 = X
810 = X
Therefore, according to the calculation that has been made, Mr. Alcazar baked 810 cookies.

Answer:
Table:
1: f(x) = 5
2: f(x)= 6
5: f(x) = 9
Points: (1,5), (2,6), and (5,9)
Step-by-step explanation:
1. The function f(x) = x + 4 means that 4 is added to the input, x, to get the output, y.
[tex]f(x) = 1 + 4 = 5[/tex] [tex]f(x) = 2 + 4 = 6[/tex] [tex]f(x) = 5 + 4 = 9[/tex]Therefore, when x = 1 then f(x) = 5, x = 2 then f(x) = 6, and x = 5 then f(x) = 9.
2. Now, to find the points, we must know that x is the x-coordinate and f(x) is the y-coordinate of the point. Because of this, the points are:
[tex](1,5)[/tex] [tex](2,6)[/tex] [tex](5,9)[/tex]Therefore, the points are (1,5), (2,6), and (5,9).
