solving slope with work tho please
Answer:
First is 5/2
second is 1
Answer:
1. A. slope = 5/2
2. A. slope = 1
Step-by-step explanation:
To find the slope you can input the x and y values of two points into this expression: [tex]\frac{y2 -y1}{x2 - x1}[/tex]
1. To find the slope, I'm going to use points (2, 3) and (4, 8). Let's input them into the expression:
[tex]\frac{8-3}{4-2}[/tex]
Simplify:
8 - 3 = 5
4 - 2 = 2
The slope is 5/2.
2. To find the slope, I'm going to use points (0, 0) and (1, 1). Let's input them into the expression:
[tex]\frac{1-0}{1-0}[/tex]
Simplify:
1 - 0 = 1
1 - 0 = 1
The slope is 1/1, or just 1.

Mr. Stack and Coach Pugh are racing down the highway. Coach Pugh is going five miles more an hour than twice Mr. Stack's speed. If Coach Pugh is going one hundred and five miles and hour, how fast is Mr. Stack going?
Answer:
50
Step-by-step explanation:
2(Mr stack's speed) = Coach Pugh's speed - 5mph
Mr stack's speed = (105mph - 5mph)/2
Mr stack's speed = 100mph/2
Mr stack's speed = 50mph

Answer:
[tex]\theta \:=43.76^{\circ \:\:}[/tex]
Step-by-step explanation:
The right triangle has the hypotenuse = 18
Let 'Ф' be the missing angle
we know that
cos Ф = adjacent/hypotenuse
Here,
The adjacent to Ф = 13The hypotenuse = 18so
cos Ф = adjacent/hypotenuse
[tex]cos\:\theta \:=\frac{13}{18}[/tex]
[tex]\theta \:=\cos ^{-1}\left(\frac{13}{18}\right)[/tex]
[tex]=43.76^{\circ \:}[/tex]

The difference between two same side interior angles of two parallel lines is 35 degrees. Find the measures of these two angles.
Answer:
107.5° and 72.5°
Step-by-step explanation:
x + y = 180 same side interior angles of two parallel lines add up to 180
x - y = 35
___________
2x = 215 add above two equations
x = 107.5° divide by 2 to isolate x
Substitution to find y:
x + y = 180
107.5 + y = 180
y = 72.5°
The measure of these two angles is 107.5° and 72.5°.
Given that,
The difference between two same-side interior angles of two parallel lines is 35 degrees.We need to find the measure of the two angles. Here we assume the two angles be x and y.Based on the above information, the calculation is as follows:
x + y = 180
And,
x - y = 35
So, after solving it, it comes
2x = 215
x = 107.5°
So, y = 180 - 107.50 = 72.5
Therefore we can conclude that the measure of these two angles is 107.5° and 72.5°.

Jasim has invested 600 dinars in a business at the rate of 4 % for 3 years. Find his
i- simple interst ?
ii- total amount after 3 years
Answer:
1) Simple interest is 72 dinars
2) Total amount after 3 years is 672 dinars.
Step-by-step explanation:
Principal Amount P = 600 dinars
Interest Rate= 4% = 0.04
Time = 3 years
i) Simple Interest
The formula used to calculate interest is [tex]I=P\times r \times t[/tex]
Putting values and finding interest
[tex]I=P\times r \times t\\I=600\times 0.04 \times 3\\I=72[/tex]
So, simple interest is 72 dinars
ii) Total amount after 3 years
The formula to calculate total amount is: [tex]A=P(1+rt)[/tex]
Putting values and finding future amount A
[tex]A=P(1+rt)\\A=600(1+(0.04*3))\\A=600(1+0.12)\\A=600(1.12)\\A=672[/tex]
So, Total amount after 3 years is 672 dinars.

a distributor wants to make 1000 pounds of trail mix that is 8% raisins. He will use a mix that is 5% raisins and a mix that is 20% raisins. How many pounds of each should he use?
Answer:
200 pounds 20% raisins
800 pounds 5% raisins
Step-by-step explanation:
Let number of 5% be x
and number of 20% be y
x + y = 1000
Also;
5% of x + 20-% of y = 8% of 1000 pounds
= 0.05x + 0.2y = 80
From i , x = 1000-y
0.05(1000-y) + 0.2y = 80
50-0.05y + 0.2y = 80
0.15y = 30
y = 200
x = 1000 - y
= 1000-200 = 800
He will use 800 pounds for a mix that is 5% raisins and 200 pounds for a mix that is 20% raisins.
Given that,
A distributor wants to make 1000 pounds of trail mix that is 8% raisins.
He will use a mix that is 5% raisins and a mix that is 20% raisins.
We have to determine,
How many pounds of each should he use.
According to the question,
Let number of 5% raisins be x,
And number of 20% raisins be y.
Then,
He will use a mix that is 5% raisins + A mix that is 20% raisins = Distributor trail mix.
[tex]x + y = 1000[/tex]
And,
He will use a mix that is 5% raisins of x + and a mix that is 20% raisins of y = 1000 pounds of trail mix that is 8% raisins.
5% of x + 20% of y = 1000 of 8% raisins
[tex]0.05 x+ 0.20y = 80[/tex]
On solving both the equation,
[tex]x + y =1000\\\\x = 1000-y[/tex]
Substitute the value of x in the equation 2,
[tex]0.05 (1000-y) + 0.20y = 80\\\\0.05 \times 1000 - 0.05y + 0.20y = 80\\\\50 + 0.15y = 80\\\\0.15y = 80-50 \\\\0.15y = 30\\\\y = \dfrac{30}{0.15}\\\\y = 200[/tex]
Substitute the value of y in the equation 1,
[tex]x + y = 1000\\\\x + 200 = 1000\\\\x = 1000-200\\\\x = 800[/tex]
He will use x = 800 pounds a mix that is 5% raisins and y = 200 pounds for a mix that is 20% raisins.
Hence, He will use 800 pounds for a mix that is 5% raisins and 200 pounds for a mix that is 20% raisins.

A company that teaches self-improvement seminars is holding one of its seminars in Belmont. The company pays a flat fee of $250 to rent a facility in which to hold each session. Additionally, for every attendee who registers, the company must spend $4 to purchase books and supplies. Each attendee will pay $14 for the seminar. Once a certain number of attendee register, the company will be breaking even. How many attendees will that take?
Answer:
Step-by-step explanation:
250 for place 4 for books each.
If they charge 14 per person, 4 of that goes for the books and 10 will be applied to the rental fee.
250/10= 25 people to break even. Any people beyond that is a profit of 10.00 since the other 4 will still go to the books.
