Amanda buys 4 tickets to the baseball game for $24 each. Which equation
shows the closest estimate of the total amount Amanda spends?
Which equation shows the closest estimate of the total amount Amanda spends
Answer:
$96
Step-by-step explanation:
Given that,
The total number of tickets = 4
Cost of each baseball = $24
We need to find the equation that shows the closest estimate of the total amount Amanda spends.
Total cost = No. of tickets × Cost of each baseball
= 4×24
= $96
Hence, the total cost is $96.

Firat slide is for #1, and second one is for #2
Answer:
#1 is the AA postulate
Step-by-step explanation:
It is the AA postulate because both triangles have congruent angles, making the triangles similar.
1. By using Angle-Angle (AA) Similarity Postulate triangle PRQ and STU are similar.
2. By using Angle-Angle (AA) Similarity Postulate triangle ABC and DEC are similar.
What is Similarity of Triangles?If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are comparable. Similar figures are described as items with the same shape but varying sizes, such as two or more figures.
Given:
1. From Figure
In triangle PRQ and STU
<RPQ = <UST
and, <PQR = <STU
Thus, By using Angle-Angle (AA) Similarity Postulate
triangle PRQ and STU are similar.
2. From Figure
In triangle ABC and DEC
<ACB = <ECD (Vertical opposite angle)
and, <BAC = <CDE (Alternate Interior Angle)
Thus, By using Angle-Angle (AA) Similarity Postulate
triangle ABC and DEC are similar.

What is the rate of change of function g?
Answer:
The rate of change of function g is: 3/2
Step-by-step explanation:
Given the table of function g
x y
2 4
4 7
6 10
8 13
We know that rate of change is also termed as the slope of the function.
Thus,
let us take any two points, let say
(2, 4) and (4, 7)
Determining the slope between (2, 4) and (4, 7)
(x₁, y₁) = (2, 4)
(x₂, y₂) = (4, 7)
Using the formula
Rate of change or Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [7 - 4] / [4 - 2]
= 3 / 2
Thus, the rate of change of function g is: 3/2

Find (x³+x²-20x+24) divided by (x-3)
Answer:
[tex]\frac{x^3 + x^2 -20x + 24}{x-3} = x^2 +4x-8[/tex]
Step-by-step explanation:
Given;
p(x) = x³ + x²- 20x + 24
factor of p(x) = x-3
Apply long division method;
x² + 4x - 8
------------------------------
x - 3 √ x³ + x²- 20x + 24
-( x³ - 3x²)
-------------------------------
4x² - 20x + 24
-(4x² -12x )
-------------------------------
-8x + 24
- (-8x + 24)
-----------------------------------------

[tex]thus, \ \frac{x^3 + x^2 -20x + 24}{x-3} = x^2 +4x-8[/tex]
What is the slope...?
Answer:
slope = -2
Step-by-step explanation:
To find the slope, you can use the slope formula, [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line passes through, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point the line also passes through.
So, in order to answer the question, we need two points from the line. To find these points, look at the x and y values of the table - they form points. Thus, (-2, 0) and (-1,-2) would be two points the line passes through. Use those x and y values and substitute them into the formula. Then, solve:
[tex]slope = \frac{y_2-y_1}{x_2-x_1}\\= \frac{(-2)-(0)}{(-1)-(-2)}\\= \frac{-2-0}{-1+2} \\= \frac{-2}{1} \\= -2[/tex]
Thus, the slope is -2.

consider the graphs of the functions f(x)=10x and g(x)= log x. describe the relationship between these functions
Answer:
The functions are inverse functions. F is exponential and g is logarithmic.
Step-by-step explanation:
Answer:
Function f is an exponential function with a base of 10, and function g is a logarithmic function with a base of 10. These two functions are inverse functions. The values in the domain of function f are the values in the range of function g, and the values in the range of function f are the values in the domain of function g. The graph of function g is the graph of function f reflected over the line y=x The two functions have similar, but inverse, features. For example, function f has a horizontal asymptote of y=0 and crosses the y-axis at (0,1) while function g has a vertical asymptote at x=0 and crosses the x-axis at (1,0)

2(4x-2)=8(x-7)
Answer:
First use the distributive property.
2(4x) 2(-2) = 8(x) 8(-7)
You will get 8x - 4 = 8x - 56
This answer has no solutions since -4 does not equal -56.
Answer: no solution
Step-by-step explanation: So i'm guessing we're solving for x? no sweat
First Distribute the constants on the outside of the expression so 2(4x-2)=8(x-7) becomes 8x-4=8x-56 right now we have a problem. X is on both sides and we don't want that cause it complicates things so we want our variable x in this case on one side. if you subtract 8x from either side your left with no variable so there is no solution.

How many solutions does the following equation have ?
- 32 +9 – 2x = -12 – 5x
Choose 1 answer:
No solutions
B
Exactly one solution
С
Infinitely many solutions
Answer:Exactly one solution.
Step-by-step explanation:
- 32 +9 – 2x = -12 – 5x
1.Add numbers
-23 - 2x= -12-5x
2.Rearrange terms
-2x - 23 = -12 - 5x
3. Rearrange terms
-2x - 23 = -5x-12
4. Add 23 to both sides of the equation
-2x-23+23= -5x-12+23
5.Simplify
-2x= -5x+11
6.Add 5x to both sides of the equation
-2x+5x=-5x+11+5x
7.Simplify
3x=11
8.Divide both sides of the equation by the same factor
[tex]\frac{3x}{3}[/tex] = [tex]\frac{11}{3}[/tex]
9.Simplify and Solution
x= [tex]\frac{11}{3}[/tex]

11 divided by 8 step-by-step guide
Step 1
The first step is to set up our division problem with the divisor on the left side and the dividend on the right side, like we have it below:
8 1 1
Step 2
We can work out that the divisor (8) goes into the first digit of the dividend (1), 0 time(s). Now we know that, we can put 0 at the top:
0
8 1 1
Step 3
If we multiply the divisor by the result in the previous step (8 x 0 = 0), we can now add that answer below the dividend:
0
8 1 1
0
Step 4
Next, we will subtract the result from the previous step from the second digit of the dividend (1 - 0 = 1) and write that answer below:
0
8 1 1
- 0
1
Step 5
Move the second digit of the dividend (1) down like so:
0
8 1 1
- 0
1 1
Step 6
The divisor (8) goes into the bottom number (11), 1 time(s), so we can put 1 on top:
0 1
8 1 1
- 0
1 1
Step 7
If we multiply the divisor by the result in the previous step (8 x 1 = 8), we can now add that answer below the dividend:
0 1
8 1 1
- 0
1 1
8
Step 8
Next, we will subtract the result from the previous step from the third digit of the dividend (11 - 8 = 3) and write that answer below:
0 1
8 1 1
- 0
1 1
- 8
3
So, what is the answer to 11 divided by 8?
If you made it this far into the tutorial, well done! There are no more digits to move down from the dividend, which means we have completed the long division problem.
Your answer is the top number, and any remainder will be the bottom number. So, for 11 divided by 8, the final solution is:
1
Remainder 3

Just divide them each
4/5 = .8
7/10 = .7
Umm... your going to have to put those on the number line yourself sorry
Answer: 4/5. 4/5 can also mean 8/10. 8/10 is greater than 7/10. I do not know how to label the fraction on the number line if it is a picture so hopefully you can do that.
