Hey guys I have a hard time with these questions. Can someone explain it to me? :)
Answers
This is basically how you do it if you need more help let me know
Answer:
Step-by-step explanation:
there are a couple ways to find slope
1. Rise over Run Method:
for this method, you use basic counting
to do this, you count the number of x spaces it takes the line to get from one y space to the next
for your line, the run is 3 because it takes 3 x spaces to get from one whole number to the next on the y spaces
you would say the rise is -1 because the line is going down, and it takes 3 x spaces to get the next pot that is on a y-axis increment
so we know the rise is -1 and the run is 3
if you put this into rise/run format, you get 1/-3
so -1/3 is you slope
2. Using the Coordinates
in this line, you see two points
the points are 1. (-1, -1), and 2. (2, -2)
using the coordinates means that you use a formula: [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
the y2 is the y value of the second coordinate (-2), the y1 is the y value of the first coordinate (-1)
the x2 is the x value of the second coordinate (2), the x1 is the x value of the first coordinate (-1)
if you plug these it you get: -2 - (-1) / 2 - (-1)
this can be simplified to -2 + 1 / 2 + 1
and simplified again to -1/3
Qhat ever method you use, you should get the same answer. Using both methods is a good way to check your work.

Write 32 +24 as a product of two factors using the gcf and the distributive property
Answers
Answer:
4 * 14
Step-by-step explanation:
Given
32 + 24
Required
Write as a product of two factors
First, we need to get the GCF of 32 and 24
The factors of 32 and 24 are:
[tex]32 = 1, 2, 4, 8, 16, 32.[/tex]
[tex]24 = 1, 2, 3, 4, 6, 8, 12, 24[/tex]
The GCF (greatest common factor) is 8
So, the expression 32 + 24 can be rewritten as:
[tex]32 + 24= 4(8 + 6)[/tex]
Add 8 + 6
[tex]32 + 24= 4(14)[/tex]
[tex]32 + 24= 4 * 14[/tex]
Hence,
32 + 24 can be rewritten as 4 * 14

Calculating income with Commission
A salesperson earns $600 per month plus a commission of 20% of sales. Find the minimum amount of sales need to receive a total income of at least $1500 per month.
Answers
Answer:
$4500Step-by-step explanation:
Step one:
given data
monthly earning= $600
commission =20%= 0.2
let the number of sales be x
and the total earnings be y
Hence the expression for the earnings is given as
y=0.2x+600
Step two:
Required:
the value of x. when y=$1500
1500=0.2x+600
1500-600=0.2x
900=0.2x
divide both sides by 0.2
x=900/0.2
x=4500
The minimum amount of sales need is $4500

Write equations (both, Point Slope & Slope Intercept Forms) of the line with
slope of -2 and point (9,2).
Answers
Answer:
Equation of line in Point Slope Form is [tex]\mathbf{y-2=-2(x-9)}[/tex]
Equation of line in Slope Intercept Form is: [tex]\mathbf{y=-2x+20}[/tex]
Step-by-step explanation:
We need to write equation of line having slope -2 and point (9,2)
a) Equation in Point Slope Form
The general equation of point slope form is: [tex]y-y_1=m(x-x_1)[/tex]
Where x₁ and y₁ are the points of line and m is slope.
x₁=9 and y₁=2 and m=-2
Putting values in formula and finding equation:
[tex]y-y_1=m(x-x_1)\\y-2=-2(x-9)[/tex]
So, Equation of line in Point Slope Form is [tex]\mathbf{y-2=-2(x-9)}[/tex]
b) Equation in Slope Intercept Form
The general equation of Slope Intercept Form is: [tex]y=mx+b[/tex]
where m is slope and b is y-intercept
Finding y-intercept using slope m=-2 and point(9,2)
[tex]y=mx+b\\2=-2(9)+b\\2=-18+b\\b=2+18\\b=20[/tex]
The equation in slope m=-2 and b=20 is:
[tex]y=mx+b\\y=-2x+20[/tex]
So, equation of line in Slope Intercept Form is: [tex]\mathbf{y=-2x+20}[/tex]

Answer: A. 5:4 Step-by-step explanation: Since the question mentions twelfths of a pie, it is easier to say each pie has 12 pieces or 36 total pieces ordered from the 3 pies. Ty ate 5 and Rob ate 15 which is 3 times more than Ty. A total of 20 pieces have been eaten from the 36 you started with. Eaten = 16. So the ratio is 20:16 which is simplified to = 20 and Remaining 5:4.
3. Repeat this process to find the width and height of a newer 48-inch television whose
screen has an aspect ratio of 16:9.
Do not include units in your answer - write only the Mumber rounded to the nearest tenth
What is the height?
Answers
Answer:
23.5"Step-by-step explanation:
Please see attached a sketch of the television
the size of a television is described by the length of its diagonal in inches.
in this case, the diagonal of the television is 48"
we are told that the aspect ratio is 16:9
hence the dimension of the television as seen from the draft is
length= 16x
height=9x
Applying Pythagoras theorem
(16x)^2+(9x)^2= 48^2
256x^2+81x^2=2304
337x^2=2304
divide both sides by 337 we have
x^2=2304/337
x^2=6.8367
x=√6.8367
x=2.6
What is the height
H=9x
=9(2.6)

The highest number here is 2.01, so we start by looking for an answer that begins with 2.01. Then we compare 1.48, 1.237,1.234, and 1.2. Look into the tenths place to find that 1.48 has a larger tenths place than any other number. continue this cycle to have the full correct order.
A group of four friends attend a movie. The expression below represents the total
amount of dollars spent by the group after purchasing four tickets, P small bags of
popcorn, and D drinks,
32 + 5P + 3D
Answers
Question Requirement:
Simplify expression that represents the total cost of tickets and snacks or beverages
Answer:
The total cost of tickets, snacks and beverages =
$54
Step-by-step explanation:
The first thing here is to ascertain the prices of each item (ticket, a bag of popcorn, and drinks). We assume that the price of the ticket is $8 (32/4) since there are four tickets for four friends, and $8 x 4 = $32. Now, we also assume that a small bag of popcorn costs $2 while drinks cost $4 each.
From the equation, we can ascertain that 5 bags of popcorn were bought while 3 bottles of drinks were purchased.
Since the total cost spent is represented by the expression,
32 + 5P + 3D
Therefore, the total cost spent by the four friends
= 32 + (5 * 2) + (3 * 4)
simplifying the above expression
= 32 + 10 + 12
= $54

(Car repair) The bill including parts and labor for the repair of your car is shown. From what is given, can you determine how many hours were spent on labor ? Explain.
Answers
Answer:
2.25 hours or 2 hours and 15 minutes
Step-by-step explanation:
Using the information from the bill shown in the question we can determine the number of hours spent by first subtracting the amount of money spent on parts from the overall total, which would leave us with the total amount spent on labor. Now we would simply divide this by $44 which is how much each hour of labor costs. Finally, this would leave us with the total number of hours of labor that the mechanic put into the car repair.
$384 - $285 = $99
$99 / 44 = 2.25 hours or 2 hours and 15 minutes (0.25 * 60 minutes)

What is the equivalent amount in year ten of an expenditure of $5,000 in year one, $6,000 in year two, and amounts increasing by $1,000 per year through year ten?
Answers
Answer:
The correct answer is the equivalent amount is $139,059.41
Step-by-step explanation:
According to the scenario, the computation of the equivalent amount in year ten is shown below;
= $5,000 × (P/A, 10%,10) + $1,000 × (P/G, 10%,10)
= $5,000 × 6.1466 + $1,000 × 22.8913
= $30,723 + $22,891.30
= $53,614.30
Now the equivalent amount is
= $53,614.30 × (F/P, 10%,10)
= $53,614.30 × 2.5937
= $139,059.41
Hence, the equivalent amount is $139,059.41

Answers
Answer:
7.2 *10⁻⁵
Step-by-step explanation:
Given the diameter of the hair expressed as 0.000072, we are to express it in scientific notation.
The standard form of scientific notation is expressed as;
A * 10ⁿ
A is a value from 1 to 9
n is any integer.
Rewriting 0.000072 in this form, we will need to shift the decimal point to the front 5 times to have;
0.000072 = 7.2 *10⁻⁵ where;
A = 7.2 and n = -5
Note that the power is a negative value since the value is less than 1.

Perimeter,s=(a+b+c)/2
Area= √s(s−a)(s−b)(s−c)
S=(AB+BC+AC)/2
=(5+7+8)/2

=10cm
Area of ABC= √10(10-5)(10-7)(10-8)

Find the rate of change
Answers
Answer:
The rate of change of function is: 2
Step-by-step explanation:
Using the given table we have to exclude two pairs of input and output.
The rate of change or slope of function is given as:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
We take first two pairs of input/output from the table
(x1,y1) = (1,11)
(x2,y2) = (2,13)
Putting the values
[tex]m = \frac{13-11}{2-1}\\m =\frac{2}{1}\\m = 2[/tex]
Hence,
The rate of change of function is: 2

Step-by-step explanation:
According to the central angle theorem, an inscribed angle is always twice the measure of the central angle.
Thus, the central angle A, is 180°, because it is a straight angle.
Therefore, the measure of the inscribed angle, <BCE would be ½ of 180°.
m<BCE = 90°
