Answer:
17 regular popcorn bags and 23 super size bags.
Step-by-step explanation:
A group of 40 people went to the theme park. While there, each person bought popcorn.
Let the regular popcorn bags be = x
Let the super size bags be = y
[tex]x+y=40[/tex] ................(1)
Next equation becomes:
[tex]6x+8y=286[/tex] ...............(2)
Multiplying (1) by 6 : [tex]6x+6y=240[/tex]
Now subtracting this from (2) we get,
[tex]2y=46[/tex]
=> y = 23
And x = [tex]40-23[/tex]
=> x = 17
So, there were 17 regular popcorn bags and 23 super size bags that the group bought.

Answer:
The number of gallons of gas Karl used is 15 gallons.
Option (C) is correct.
Step-by-step explanation:
As given
Karl drove 617.3 miles.
For each gallon of gas, the car can travel 41 miles.
i.e
1 gallons = 41 miles
[tex]1\ miles = \frac{1}{41}\ gallons[/tex]
Now find out for the 617.3 miles.
Thus
[tex]617.3\ miles = \frac{617.3}{41}\ gallons[/tex]
[tex]617.3\ miles = 15.1\ gallons[/tex]
[tex]617.3\ miles = 15\ gallons\ (Approx)[/tex]

Answer:
x=3
Step-by-step explanation:
Since this is an isosceles trapezoid
The angles at the top have to equal each other
112 = 30x + 11y
The sides also have to equal each other.
12 = 2x+3y
Divide each side by 3
12/3 = 2x/3 + 3y/3
4 = 2/3 x +y
Subtract 2/3 x from each side
4 -2/3 x =y
Substitute this into the first equation
112 = 30x + 11y
112 = 30x +11(4-2/3x)
112 = 30x +44 -22/3 x
Subtract 44 from each side
112-44 = 30x +44-44 -22/3 x
68 = 30x -22/3 x
Get a common denominator on the right of 3
68 = 90/3x -22/3 x
68 = 68/3 x
Multiply each side by 3/68
68 * 3/68 = 68/3 * 3/68 x
3 =x

Find the area of the rectangle. Round the answer to the nearest whole number.
Answer:
The area of the given rectangle is 51
Step-by-step explanation:
First we have to find the coordinates of the vertices of the rectangle.
Then the length and breadth of it using distance formula.
The distance d between points (x₁ , y₁) and (x₂ , y₂) is given by
[tex]d= \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
Finally calculate the area of rectangle using the formula,
Area of rectangle = Length * Breadth
From the given graph, we get the coordinates of the rectangle as
A(2,4) , B(-2,3) , C(1,-9) , D(5,-8)
Breadth, AB = [tex]\sqrt{(-2-2)^{2}+(3-4)^{2}} = \sqrt{16+1} = sqrt{17}[/tex]
Length, BC = [tex]\sqrt{(1+2)^{2}+(-9-3)^{2}} = \sqrt{9+144} = 3 sqrt{17}[/tex]
Now, Area of rectangle = Length * Breadth = AB * BC = √17 * 3√17 = 3 *17 = 51
∴ The area of the given rectangle is 51

Find the slope of the line passing through the points (8,-6)
and (4,-8)
.
Answer:
1/2 is the slope of the line
Step-by-step explanation:
To find slope, use the following equation
slope (m) = (y₂ - y₁)/(x₂ - x₁)
First, set each coordinate. Let:
(x₁ , y₁) = (8 , -6)
(x₂ , y₂) = (4 , -8)
Plug in the corresponding numbers for the corresponding variables.
m = (y₂ - y₁)/(x₂ - x₁)
m = (-8 - (-6))/(4 - 8)
Simplify. Note that two negative signs would result in a positive sign.
m = (-8 + 6)/(4 - 8)
Combine like terms.
m = -2/-4
Simplify. Divide common factors from both the numerator and denominator.
m = (-2/-4)/(-2/-2) = 1/2
1/2 is the slope of the line

Bob bought a megahunk chocolate bar that weighed 9/10 lb he has already eaten 1/3 lb how much chocolate dose he have left
A 7/15
B 17/30
NEED ANSWERS FAST
Hi there! :)
Answer:
The answer is B) 17/30
Step-by-step explanation:
In order to find your answer you need to subtract 1/3 from 9/10:
9/10 - 1/3 = chocolate left
Since theses fractions do not have the same denominators (bottom number), the key here is to rewrite both of the fractions so that they have the same denominator:
The denominator is going to be a common multiple of "10" and "3". Ideally it's going to be the least common multiple of "10" and "3".
Let's start with the larger of the two denominators, which is "10". You have to go through its multiples and and see when we get to one that's divisible perfectly by 3.
So 10 is not divisible perfectly by 3, neither is 20. 30 on the other hand is divisible perfectly by 3. 30 is three times 10.
So you can rewrite both of these fractions as something over 30.
1/3 = ?/30
To get from 3 to 30, we have to multiply by 10. So if you multiply the denominator by 10, if you don't want to change the value of the fraction, you have to multiply the numerator (top number) by 10 also.
1/3 = 10/30
Same thing with the other fraction:
9/10 = ?/30 → 3 × 10 = 30 / SO, you need to multiply the numerator by three also → 9 × 3 = 27
9/10 = 27/30
Now that your fractions both have the same denominator, you can subtract the numerators together and put the answer on 30.
27/30 - 10/30 = ?
27 - 10 = 17 → 17/30
Since the fraction is simplified, you are now done.
There you go! I really hope this helped, if there's anything just let me know! :)

Which of the following circles lie completely within the fourth quadrant?
Check all that apply.
A. (X-12)^2 + (y+0)^2= 72
B. (X-2)^2 + (y+7)^2= 64
C. (X-9)^9 + (y+9)^2= 16
D. (X-9)^2 + (y+5)^2= 9
Answer:
C. (X-9)^9 + (y+9)^2= 16
D. (X-9)^2 + (y+5)^2= 9
Step-by-step explanation:
The formula for a circle is
(X-h)^2 + (y-k)^2= r^2
where (h,k) is the center of the circle and r is the radius
The 4th quadrant is where x is positive and y is negative
Add r to the y coordinate of the center and if it is still negative, the circle is still completely in the 4th quadrant
A. (X-12)^2 + (y+0)^2= 72
The center is at 12,0 and the radius is sqrt(72) = 6sqrt(2)
This will be positive so it goes into the 1st quadrant
B. (X-2)^2 + (y+7)^2= 64
The center is at 2,-7 and the radius is 8
-7+8=1 so it goes into the 1st quadrant
C. (X-9)^9 + (y+9)^2= 16
The center is at 9,-9 and the radius is 4
-9+4 = -5 so it is completely in the 4th quadrant
D. (X-9)^2 + (y+5)^2= 9
The center is at 9,-5 and the radius is 3
-5+3 = -2 so it is completely in the 4th quadrant
Answer:
C and D
Step-by-step explanation:
The fourth quadrant is the bottom, right quadrant. In the fourth quadrant, the x-coordinate is positive, and the y-coordinate is negative.
For a circle to be completely within the fourth quadrant, the circle must have its center in the fourth quadrant, and the center has to be far away enough from the positive x-axis and from the negative y-axis, that no points on the circle are outside the fourth quadrant.
Choice A has center (12, 0), so it cannot be.
Choice B has center (2, -7) and radius 8. Many points will be past the axes.
Choice C has center (9, -9) and radius 4. All points will be in the fourth quadrant.
Choice D has center (9, -5) and radius 3. All points will be in the fourth quadrant.

Jason has 15 birdhouses to sell at a craft fair. Which inequality represents the number of birdhouses, b, he can sell at the craft fair?
b≤15
b<15
b≥15
b>15
Answer:
b≤15
Step-by-step explanation:
If he only has 15 birdhouses in stock, then he can only sell 15 or less birdhouses. He cant sell more birdhouses, simply because he doesnt have more than 15.
Final answer:
The inequality representing the number of birdhouses Jason can sell, given he has 15, is b≤15 since he cannot sell more than he has.
Explanation:
The inequality that represents the number of birdhouses, b, Jason can sell at a craft fair, given he has 15 birdhouses, is b≤15. This is because the number of birdhouses he can sell cannot exceed the number he has, which is 15. The inequality b≤15 means that Jason can sell no more than 15 birdhouses, he could sell exactly 15, or he could sell less, depending on the demand at the craft fair.
This constraint ensures that Jason operates within the bounds of his available stock, preventing him from overselling. It implies that Jason can sell up to 15 birdhouses, including the possibility of selling exactly 15 or selling fewer, depending on the demand at the craft fair. This inequality serves as a practical guideline for Jason to manage his sales effectively, aligning his offerings with the limitations of his inventory.

The train travels option B. 315 miles in 7 hours.
What is Speed?Speed is the unit rate in terms of distance travelled by an object and the time taken to travel the distance.
Speed is a scalar quantity as it only has magnitude and no direction.
Given that,
Distance train travelled = 180 miles
Time taken to travel the distance = 4 hours
Speed = Distance / Time
= 180 / 4
= 45 miles per hour
Also, given that train travels at constant speed.
Distance = Speed × Time
Since speed is constant, the distance train travelled in 7 hours will be,
Distance = 45 × 7
= 315 miles
Hence the distance train travelled in 7 hours is 315 miles.

x = number of messages sent or received
y = total cost per month
Plan A costs $30 per month plus $0.10 per text message. So the cost for plan A is y = 0.10*x + 30. The portion 0.10*x represents just the cost of the 10 cents per message, and then we add on the fixed cost of $30 to get the total cost.
In a similar fashion, plan B's cost is y = 60. There is no cost per message, so we don't have to include x in the picture. The cost is a flat fee, which leads to a flat horizontal line graph (as shown in the attachment below)
Our two equations are: y = 0.10x+30 and y = 60. Let's use substitution to find x
y = 0.10x + 30
60 = 0.10x + 30 ... replace y with 60 (works because y = 60)
60-30 = 0.10x
30 = 0.10x
0.10x = 30
x = 30/0.10
x = 300
If you send or receive 300 messages, then both plans will cost the same. We can see this on the graph below where the two lines cross at (300,60). Note how plugging x = 300 into the first equation simplifies to y = 60.

The population of a town increased by 15% in 2016, and decreased by 5% in 2017. If the population of the town was 60,000 in the beginning of 2016, then what was it at the end of 2017?
Answer:
The population of the town at the end of 2017 was 65,550.
Step-by-step explanation:
The population of the town was 60,000 in the beginning of 2016.
In 2016, the total population is increased by 15%.
[tex]60,000\times\frac{15}{100}=9000[/tex]
Therefore the population is increased by 9000 and the population of the town at the end of 2016 was
[tex]60,000+9000=69,000[/tex]
In 2017, the total population is decreased by 5%.
[tex]69,000\times\frac{5}{100}=3450[/tex]
Therefore the population is decreased by 3450 and the population of the town at the end of 2017 was
[tex]69,000-3450=65,500[/tex]
Therefore the population of the town at the end of 2017 was 65,550.
16. Tell whether the lines for each pair of equations are parallel, perpendicular, or neither.

Answer:
Given equation are:
[tex]y = -\frac{1}{4}x+8[/tex] ......[1]
[tex]-2x+8y = 4[/tex] .....[2]
The two lines are parallel lines then their slopes will be equal.When two lines are perpendicular then, the slope of lines are the negative reciprocals of each other.Now, Equation of a line is in the form of y =mx+b where m is the slope of the line.
Slope[tex](m_1)[/tex] of equation of line in [1] is;
[tex]y = -\frac{1}{4}x+8[/tex]
then;
[tex]m_1= -\frac{1}{4}[/tex]
Slope[tex](m_2)[/tex] of equation of line in [2];
[tex]-2x+8y = 4[/tex]
Add both sides 2x we get;
-2x + 8y + 2x = 2x + 4
Simplify:
8y = 2x +4
Divide both sides by 8 we get;
[tex]y = \frac{1}{4} x + \frac{1}{2}[/tex]
then;
[tex]m_2 = \frac{1}{4}[/tex]
Therefore, the given two lines are neither parallel nor perpendicular.

Jim drank 2/5 of his water bottle and John drank 3/10 of his water bottle. How much did the both boys drink?
Jim and John drank a combined total of 7/10 of their water bottles, with Jim drinking 2/5 (converted to 4/10 for the common denominator) and John drinking 3/10.
To determine how much water Jim and John drank from their water bottles, we can add the fractions of the water they each drank. Jim drank 2/5 of his water bottle, while John drank 3/10 of his. To add these fractions, we need a common denominator, which in this case is 10. Convert 2/5 to 4/10 by multiplying the numerator and denominator by 2. Now, we can add 4/10 (Jim's consumption) and 3/10 (John's consumption) together.
The total amount of water drank by both boys is: 4/10 + 3/10 = 7/10
Thus, together, Jim and John drank 7/10 of their water bottles combined.
If you apply the changes below to the absolute value parent function, f(x) = |x|, what is the equation of the new function?Shift 4 units left.Shift 2 units up

B.g(x)=|x+2|+4
C.g(x)=|x+4|+2
D.g(x)=|x+2|-4
Got the answer its C.
Answer: C
Step-by-step explanation:
The general form of the equation is: g(x) = a|x - h| + k ;
"a" represents the vertical stretch (or shrink)"h" represents the x-coordinate of the vertex (left and right)"k" represents the y-coordinate of the vertex (up and down)4 units left means h = 4
2 units up means k = 2
--> g(x) = |x - 4| + 2
Option: C is the correct answer.
C. [tex]g(x)=|x+4|+2[/tex]
Step-by-step explanation:The parent function f(x) is given by:
[tex]f(x)=|x|[/tex]
Now, we know that for any parent function f(x) the transformation of the type:
f(x) → f(x+k)
is a translation of the function f(x) k units to the right if k<0
and k units to the left if k<0
and the transformation of the type:
f(x) → f(x)+k
is a translation of a function f(x) k units upward if k>0
and k units downward if k<0
Now here it is given that:
The function f(x) is shifted 4 units left and 2 units up.
Hence, the transformed function g(x) is given by:
[tex]g(x)=f(x+4)+2\\\\i.e.\\\\g(x)=|x+4|+2[/tex]

third answer is -2
fourth answer is 2
Step-by-step explanation:
Explanation to get the answers:
you plug in the b c d and a
depending on what your abc and d are will depend on how the equation goes
like for example if the equation is
a x (c) - (-d) + b
and a=5, b=8, c=10, d=15
then you plug 5 where a is
plug in 10 where c is
plug 15 where d is as a negative
and lastly plug 8 where b is
if you have a calculator/graphing calculator i would use it to help answer these equations
a graphing calculator solves it for you without doing all the extra work like you would on a regular calculator
i use the graphing calculator to help solve equations like this specific one and it works very well
i hope my answers and explanation helps you :)
