Answer:
After correcting error of Mia and solving the expression[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)[/tex] we get 14.25
Step-by-step explanation:
The given expression is:[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)[/tex]
First I solve the expression, and then will point the error
[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)\\Converting \ \div \ sign \ into \ \times the \ term \ is \ inverted\\=0.38 \times 3 \times(-20)\times5\times(-1/8)\\=0.38\times 3 \times-20\times5\times-1/8\\=1.14 \times-20\times5\times-1/8\\=-22.8\times5\times-1/8\\=-114\times-1/8\\=\frac{-114}{-8}\\=14.25[/tex]
So, the mistake Mia did was when she inverted division sign into multiplication, she didn't invert the term next to division sign.
The step she did was: [tex]0.38 \times 5 \times(1/20)\times3\times(-8)[/tex]
While the correct step was: [tex]0.38 \times 3 \times(-20)\times5\times(-1/8)[/tex]
After correcting error of Mia and solving the expression[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)[/tex] we get 14.25

What is a Polynomial?Polynomial, a mathematical expression made comprised of numbers and variables arranged in specific patterns.
As per the given data:
We are given a table where in each row and each column an expression is written, we have to fill the table correspondingly after finding out the product of each row head and column head
For row with d and column with 2d²:
= d × 2d² = 3d³
For row with d and column with 11d:
= d × 11d = 11d²
For row with d and column with -4:
= d × -4 = -4d
For row with -9 and column with 2d²:
= -9 × 2d² = -18d²
For row with -9 and column with 11d:
= -9 × 11d = -99d
For row with -9 and column with -4:
= -9 × -4 = 36
The tables should be filled in the following order:

Answer:
3 (second option)
Step-by-step explanation:
g(x) is a piecewise function. To find g(3), you have to see which condition the number 3 satisfies.
Out of the options provided, the only condition 3 satisfies is x≥3.
The equation provided for x being greater than or equal to 3 is 6 - x.
Now we can plug in our x value of 3 and solve.
g(3)= 6 - 3
g(3)= 3

Part A
Which figures have a volume greater than 600 cubic inches?
A. Cylinder #1
B. Cone #1
C. Cylinder #2
D. Cone #2
E. Sphere
Part B
How many times greater is the volume of the Sphere than the volume of
Cone #1? Round your answer to the nearest tenth.
Answer:
A). Options (C) and (E)
B). 4.8 times
Step-by-step explanation:
Part A
Volume of cylinder (1) = πr²h
= π(6)²(5)
= 565.5 cubic inches
Volume of cone (1) = [tex]\frac{1}{3}\pi (r)^2h[/tex]
= [tex]\frac{1}{3}(\pi )(6)^2(5)[/tex]
= 188.5 cubic inches
Volume of cylinder (2) = πr²h
= π(6)²(15)
= 1696.5 cubic inches
Volume of cone (2) = [tex]\frac{1}{3}\pi (r)^2h[/tex]
= [tex]\frac{1}{3}\pi (6)^2(15)[/tex]
= 565.5 cubic inches
Volume of sphere = [tex]\frac{4}{3}\pi r^{3}[/tex]
= [tex]\frac{4}{3}\pi (6)^{3}[/tex]
= 904.8 cubic inches
Figure having volume greater than 600 cubic inches are cylinder (2) and sphere.
Options (C) and (E) are the correct options.
Part (B)
[tex]\frac{\text{Volume of sphere}}{\text{Volume of cone (1)}}[/tex] = [tex]\frac{904.8}{188.5}=4.8[/tex]
Therefore, volume of sphere is 4.8 times the volume of cone (1).

Which answer choice identifies the relevant information in the problem?
Sarah left the house at 12:15 p.m. to go to the store. She spent $42.20 on 2 books for her children and she spent $5.67 on a toys for her dog, Rover. Sarah arrived home at 1:00 p.m. How much did Sarah spend on each book
Answer:
Step-by-step explanation:
Given parameters:
Time of going out = 12:15pm
Amount spend on two books = $42.20
Amount spend toys = $5.67
Time of arrival = 1:00pm
The amount Sarah spent on each of the two books;
= [tex]\frac{total amount spent on the books }{number of books}[/tex]
Amount spent on each books = [tex]\frac{42.20}{2}[/tex] = $21.1 per book
The relevant information to solve this problem are the number of books and the cost of the book.

Use the graph and the translation (x,y) → (x + 4y + 2) to answer parts a and b below.
a. Enter the image of each vertex as an ordered pair.
A → A
B → B
C → C
Use the translation formula to determine the new points.
A' → [tex](5 + 4, -8 + 2) = (9, -6)[/tex]
B' → [tex](1 + 4, -1 + 2) = (5, 1)[/tex]
C' → [tex](-7 + 4, -3 + 2) = (-3, -1)[/tex]
A' = (9, -6)
B' = (5, 1)
C' = (-3, -1)
The new coordinates are obtained as A'(-4, 7), B'(3, 1) and C'(-3, -1) respectively.
How to transform a graph of the function?The graph of a function can be transformed by either shifting it in the right, left, up or down.
When the transformation is rightwards, the function becomes as f(x - a).
For left shifting it is f(x + a).
And, for up and down shift it is a + f(x) and a - f(x) respectively.
The new coordinates after the transformation is given as follows,
Apply the given transformation (x,y) → (x + 4,y + 2) as below,
The coordinates of A' are (-8 + 4, 5 + 2) = (-4, 7).
The coordinates of B' are (-1 + 4, -1 + 2) = (3, 1).
The coordinates of C' are (-7 + 4, -3 + 2) = (-3, -1).
Hence, the coordinates after the transformation become as A'(-4, 7), B'(3, 1) and C'(-3, -1).

John gets a new job and receives a $500 signing bonus. After that, he makes $200 a day. How much money does he make after 4 days?
Answer:
John makes a total of $1,300.
Step-by-step explanation:
We know that before his bonus, John already has $500. Then, he gets $200 every day for 4 days.
200 x 4 = $800
So, over the course of those 4 days, Johnny makes $800. Now, let's add this to the rest of his money.
800 + 500 = $1,300
Therefore, John makes a total of $1,300.

Answer:
x = -149/20
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
2(x + 469/20) = 32
Step 2: Solve for x
Distribute 2: 2x + 469/10 = 32Isolate x term: 2x = -149/10Isolate x: x = -149/20Step 3: Check
Plug in x to verify it's a solution.
Substitute: 2(-149/20 + 469/20) = 32Add: 2(16) = 32Multiply: 32 = 32Here we see that 32 does indeed equal 32. ∴ x = -149/20 is a solution of the equation.
And we have our final answer!
