Answer:
30+20w=250
w=11
Step-by-step explanation:
To do this, write this equation because 30 is what she had and 20w is the weeks. We don't know the weeks so use w. Finally, put=250
30+20w=250
To solve this, do 250-30=220
So 20w=220
Divide 220/20
W=11
Answer:
11 weeks
Step-by-step explanation:
The equation would be 20w + 30 = 250
so, we need to solve w.
20w + 30 = 250
- 30 - 30
20w = 220

A line segment AB has the coordinates A (2,3) AND B ( 8,11) answer the following questions (1) What is the slope of AB? (2) What is the length of AB? (3) What are the coordinates of the mid point of AB?(4) What is the slope of a line perpendicular to AB ?
Answer:
(1) The slope of the line segment AB is 1.[tex]\bar 3[/tex]
(2) The length of the line segment AB is 10
(3) The coordinates of the midpoint of AB is (5, 7)
(4) The slope of a line perpendicular to the line AB is-0.75
Step-by-step explanation:
The coordinates of the line segment AB are;
A(2, 3) and B(8, 11)
(1) The slope of a line segment is given by the following equation;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Where;
(x₁, y₁) and (x₂, y₂) are two points on the line segment
Therefore;
The slope, m, of the line segment AB is given as follows;
A(2, 3) = (x₁, y₁) and B(8, 11) = (x₂, y₂)
[tex]Slope, \, m_{AB} =\dfrac{11-3}{8-2} = \dfrac{8}{6} = 1 \frac{1}{3} = 1.\bar3[/tex]
The slope of the line segment AB = 1.[tex]\bar 3[/tex]
(2) The length, l, of the line segment AB is given by the following equation;
[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Therefore, we have;
[tex]l_{AB} = \sqrt{\left (11-3 \right )^{2}+\left (8-2 \right )^{2}} = \sqrt{64 +36} = 10[/tex]
The length of the line segment AB is 10
(3) The coordinates of the midpoint of AB is given as follows;
[tex]Midpoint, M = \left (\dfrac{x_1 + x_2}{2} , \ \dfrac{y_1 + y_2}{2} \right )[/tex]
Therefore;
[tex]Midpoint, M_{AB} = \left (\dfrac{2 + 8}{2} , \ \dfrac{3 + 11}{2} \right ) = (5, \ 7)[/tex]
The coordinates of the midpoint of AB is (5, 7)
(4) The relationship between the slope, m₁, of a line AB perpendicular to another line DE with slope m₂, is given as follows;
[tex]m_1 = -\dfrac{1}{m_2}[/tex]
Therefore, the slope, m₁, of the line perpendicular to the line AB, that has a slope m₂ = 4/3 = 1.[tex]\bar 3[/tex] is given as follows;
[tex]m_1 = -\left (\dfrac{1}{\frac{4}{3} } \right ) = -\dfrac{3}{4} = -0.75[/tex]
The slope, m₁, of the line perpendicular to the line AB is m₁ = -0.75.

The cooper family owns a luxery sedan and a compact car the fuel tank capacity for the luxury seden is 22.45 gallon and of the compact car is 8.7 gallons find the diffrence in the fuel tank of the teo car
Given :
The cooper family owns a luxery sedan and a compact car the fuel tank capacity for the luxury seden is 22.45 gallon and of the compact car is 8.7 gallons.
To Find :
The difference in the fuel tank of the two car.
Solution :
Capacity of sedan, S = 22.45 gallons.
Capacity of compact car, C = 8.70 gallons.
Difference in the capacity :
D = S - C
D = 22.45 - 8.70 gallons
D = 13.75 gallons
Therefore, difference in the fuel tank of the two car is 13.75 gallons.
Hence, this is the required solution.
The number of basketball games that must be scheduled in a league with n teams is given by G(n) = (n2 - n)/2 where each team plays every other team exactly once. A league schedules 21 games. How many teams are in the league?
Answer:
There are 7 teams in the league
Step-by-step explanation:
Given that the number of games is given by:
[tex]G(n) = \frac{(n^2-n)}{2}[/tex]
The equation will be used to determine the number of games. As we already know, that 21 games are scheduled which means G(n) is 21 so we have to find n when G(n) is 21
Putting this mathematically
[tex]21 = \frac{n^2-n}{2}[/tex]
Multiplying equation by 2
[tex]2*21 = 2*\frac{n^2-n}{2}\\42 = n^2-n\\n^2-n-42 = 0\\n^2-7n+6n-42 = 0\\n(n-7)+6(n-7) = 0\\(n-7)(n+6)=0\\n-7 = 0 => n=7\\n+6=0 => n=-6[/tex]
As the number of teams cannot be negative, the number of teams in league are 7.
Hence,
There are 7 teams in the league

Answer:
c = 4
Step-by-step explanation:
p(x) is divisible by (x - 3).
So, p(3) = 0
-(3)³ + c(3)² - 4 *3 + 3 = 0
-27 + 9c - 12 + 3 = 0
9c - 36 = 0
9c = 36
c = 36/9

From 2010 to 2011, the population of Queens increased by 16,075. Brooklyn's population increased by 11,870 more than the population increase of Queens. a) Estimate the total combined population increase of Queens and Brooklyn from 2010 to 2011. (Round the addends to estimate.)
Answer: 44000
Step-by-step explanation:
From the question, we are informed that the population of Queens increased by 16,075.
Brooklyn's population increased by 11,870 more than the population increase of Queens. This means that Brooklyn's population will be:
= 16075 + 11870
= 27945
The total combined population increase of Queens and Brooklyn from 2010 to 2011 will then be:
= 16075 + 27945
Estimating 16075 gives 16000
Estimating 27945 gives 28000
Adding then together equals
16000 + 28000 = 44000
write an equation of the line passing through points (3,8) and (-2,-22)
Answer:
[tex]y=6x-10[/tex]
Step-by-step explanation:
First, we can find the slope using the two given points.
[tex]m=\frac{y2-y1}{x2-x1}=\frac{-22-8}{-2-3}=\frac{-30}{-5}=6[/tex]
Then, we can use the slope we just found and one of the given points to find the y-intercept.
[tex]y=mx+b\\y=6x+b\\8=6(3)+b\\8=18+b\\b=-10[/tex]
And we can put our equation together.
[tex]y=6x-10[/tex]

What is the measure of angle x?
Answer:
X=135
Step-by-step explanation:
180-69-66=45
And the angle of a line is also 180 and 180-45=135
Please help I don't want just the answer I want to know how to solve it.
Answer:
149 degrees
Step-by-step explanation:
Since m and n are parallel you need to remember the rules of transversals, this means that <1 and <2 are corresponding. Corresponding angles are always congruent, so we can solve for x by setting them equal to each other.
[tex]8x-1=7x+3[/tex]
First, move the variables to one side, I will move them both to the right, but remember you can do it on either side. To do this subtract 7x from both sides
[tex]8x-1-7x=7x+3-7x[/tex], then simplify
[tex]x-1=3[/tex]
Next, add 1 to both sides to isolate the variable
[tex]x-1+1=3+1[/tex], then simplify
[tex]x=4[/tex]
Now that you know what x equals solve for angle 1, to do this plug 4 in for x in the original equation
[tex]8(4)-1=31[/tex]
Finally, you can solve for <3 because <1 and <3 are supplementary. So to solve add both and set them equal to 180, in this equation let x stand for <3. [tex]180=31+x[/tex], then subtract 31 from both sides [tex]180-31=31+x-31[/tex] and simplify, [tex]149=x[/tex]. So angle 3 is equal to 149.

What equation in Slope-Intercept Form represents the line that passes through the points ( -3,3) and ( 1,2)?
Answer:
[tex]y=-\frac{1}{4}x+\frac{9}4}[/tex]
Step-by-step explanation:
Answer:
Step-by-step explanation:
(x₁ , y₁) = (3, -3) & (x₂ , y₂) = (1 , 2)
[tex]slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]= \frac{2-3}{1-[-3]}\\\\= \frac{-1}{1+3}\\\\=\frac{-1}{4}[/tex]
m = (-1/4)
y - y₁ = m(x - x₁)
[tex]y - 3 = \frac{-1}{4}(x - [-3])\\\\y - 3 = \frac{-1}{4} (x + 3)\\\\y - 3 = \frac{-1}{4}x-\frac{3}{4}\\\\ y = \frac{-1}{4}x-\frac{3}{4} + 3\\\\ y =\frac{-1}{4}x+\frac{-3+12}{4}\\\\ y =\frac{-1}{4}x+\frac{9}{4}[/tex]

Determine if the sequence is arithmetic write yes or no 5,9,14,20
Answer: No
Step-by-step explanation:
An arithmetic sequence is one where the same number is being added to the number before it. For example, 2, 4, 6, 8..., where 2 is being added to each number.
In this case, however, the number being added is not consistent with this pattern. Between 5 and 9, the difference is 4 and between 9 and 14, the difference is 5, and so forth. This pattern does not follow the rules of an arithemtic sequence.

Jason has a rectangular garden with the length of 10 m and a width of 3 m he will double the area of the garden by adding the same number of meters to both the length and the width what will be the length in meters of the garden after Jason in large is it
Answer:
2 m
Step-by-step explanation:
The length and width of a rectangular garden is 10 m and 3 m respectively.
He will double the area of the garden by adding the same number of meters to both the length and the width. Area = 2(10 × 3) = 60 m².
Let x is amount of increase in the length and width such that area will be :
(10+x)(3+x) =60
30+10x+3x+x² = 60
x²+13x-30=0
x²+15x-2x-30=0
x(x+15)-2(x+15)=0
x=2 and x = -15
Neglecting negative value, he aded 2 m toboth length and width of the garden.

The player began counting at 000 seconds, even though the video had already played 190190190 frames. The video plays 252525 frames per second. How many frames had the video already played when the time was equal to -3\dfrac{2}{5}−3 5 2 minus, 3, start fraction, 2, divided by, 5, end fraction seconds?
Answer:
105 frames
Step-by-step explanation:
Given that:
At 0 seconds, the video had already played 190 frames and there are 25 frames being played per second.
When the time is equal to [tex]3 \dfrac{2}{5}[/tex], the number of frames that are already being played is:
[tex]= 3 \dfrac{2}{5} \times 25[/tex]
[tex]= \dfrac{17}{5} \times 25[/tex]
= 17 × 5
= 85 frames.
But recall that, the frames had already played 190 frames at 0 seconds, then the number of frames that had already been played when the time is equal to [tex]3 \dfrac{2}{5}[/tex] is;
=(190 - 85) frames
= 105 frames
