You and a friend are trying to decide whether going to the movie theater or renting a film to watch at home would cost less. At Theater
Y, the cost of a ticket for young adults ages 10-18 is $7.75. A medium drink costs $2.50 and a small popcorn costs $2.50. Conversely,
it costs $4.50 to rent a movie, $1.50 for a 2 liter of cola, and $2.00 for a bag of microwave popcorn. Which option would cost less and
by how much?
Home by $17.50
Theater Y by $8.00
Theater Y by $17.50
Home by $8.00
Answers
Answer:
Home by $17.50
Step-by-step explanation:
Home by 17.50 because when going to the theater you have to consider all the costs of everything you will be purchasing so there will be 2 tickets for yourself and your friend 2 drinks and 2 small popcorns when you add all of these up it will look like this 7.75+7.75+2.50+2.50+2.50+2.50 = 25.50 then I will subtract this from the at home cost so 25.50 - 4.50 - 1.50 - 2.00 = 17.50 So it's cheaper home by 17.50

Find the gradient of the curve y = x^5/2 at the point where x = 4
Answers
Given:
The equation of the curve is:
[tex]y=x^{\frac{5}{2}}[/tex]
To find:
The gradient of the given curve at the point where [tex]x = 4[/tex].
Solution:
We have,
[tex]y=x^{\frac{5}{2}}[/tex]
Differentiate with respect to x.
[tex]y'=\dfrac{5}{2}x^{\frac{5}{2}-1}[/tex] [tex][\because \dfrac{d}{dx}x^n=nx^{n-1}][/tex]
[tex]y'=\dfrac{5}{2}x^{\frac{3}{2}}[/tex]
Substituting [tex]x=4[/tex], we get
[tex]y'=\dfrac{5}{2}(4)^{\frac{3}{2}}[/tex]
[tex]y'=\dfrac{5}{2}(2^2)^{\frac{3}{2}}[/tex]
Using properties of exponents, we get
[tex]y'=\dfrac{5}{2}(2)^{2\times \frac{3}{2}}[/tex] [tex][\because (a^m)^n=a^{mn}][/tex]
[tex]y'=\dfrac{5}{2}(2)^{3}[/tex]
[tex]y'=\dfrac{5}{2}(8)[/tex]
[tex]y'=20[/tex]
Therefore, the gradient of the given curve at the point where [tex]x = 4[/tex] is 20.

Answer:
7) circumference = 11.78 ft
8) arc NMP = 198° or 27.63 ft
Step-by-step explanation:
7) circumference = πd = (3.14) (3 3/4) = 11.78 ft
8) radius = 8 ft
diameter = 2 x 8 = 16 ft
arc NM + arc QP = 360° - 162° - 162° = 36°
arc NM = arc QP because they are arcs of vertical angles.
arc QP = 18°
arc NMQ = 180°
arc NMP = 180° + 18° = 198°
circumference = πd = (3.14)(16) = 50.24 ft
(198°/360°)(50.24) = 27.63 ft

What is the surface area of a cube with a side length of 3/4 inch? Use the expression 6s 2, where is the side length of the cube
Answers
Answer: The surface area of the cube would be 3^3/4.
Step-by-step explanation:
A cube has 6 faces [ 6 surfaces ]. Each surface has a square shape.
The area of 1 surface= (side)^2= 3/4 · 3/4= 9/16 sqr.in.
Surface area of cube =9/16 · 1/6= 54/16.
divide both top and bottom (54 and 16) by 2. you should end up with 27/8.
27/8 = 3^3/4 sqr. in.
Hope this helps.

Jacob sold 40 candy bars and made $65. He sold two types of
bars - chocolate for $2 each and peanut butter for $1 each.
How many of each type of candy bar did Jacob sell?
Answers
Answer:
Jacob sold 25 bars - chocolates and 15 peanut butter.
Step-by-step explanation:
Jacob sold 40 candy bars.
Let the bars - chocolate be x and peanut butter be y and made $65.
Now,
x + y = 40 ...(1)
2x + y = 65 ...(2)
Now, From equation (1) we get,
x + y = 40
x = 40 - y
Now, put the value of x = 40 - y in equation (2) we get,
2x + y = 65
2(40 - y) + y = 65
80 - 2y + y = 65
y = 80 - 65
y = 15
Now, put the value of y in equation (1)
x + y = 40
x + 15 = 40
x = 40 - 15
x = 25
The bars - chocolate = x = 25 and
peanut butter = y = 15
Thus, Jacob sold 25 bars - chocolates and 15 peanut butter.

747 = (9 times x) + 9
Answers
Answer:
x=82
Step-by-step explanation:
You start of with subtracting both sides with 9
then you divide both side with 9
Remember the rule that whatever you do to one side, you have to do to the other side. So, how do we find x? The objective when we are simplifying equations like this is to isolate x. We need to make x lonely on one side. So let's try!
747 = 9x + 9
What is the first step to making x lonely? Usually try to use the property of addition or subtraction because it makes things 10x easier. So, using the idea of using addition or subtraction, let's make x lonely by minusing 9 on both sides.
747 = 9x + 9
- 9 - 9 (Remember we have to do the same thing to both sides!)
738 = 9x
Now we have 9 times x = 738. Hm, how do we make x lonely even more? What if divide both sides by 9. We are dividing both sides by 9 because this way, the 9 times will cancel out and disappear. Look:
738 = 9x
÷9 ÷9
82 = x
And there we go, we made x completely lonely and found out x = 82!
