Answer:
Step-by-step explanation:
Call the movie length m
3/4 m = 1 1/2 hours
3/4 m = 3/2 hours
This is easier to do by decimals
3/4 = 0.75
3/2 = 1.5
0.75 m = 1.5 Divide by 0.75
0.75/0.75 m = 1.5/0.75
m = 2
If it must be done using fractions then this is how it works.
3/4 m = 3/2
[tex]\frac{3*m}{4}=\frac{3}{2}\\m=\frac{\frac{3}{2} }{\frac{3}{4} }[/tex]
[tex]m= \frac{3}{2}*\frac{4}{3}\\\text{The threes cancel out. So does 2 into 4}[/tex]
You get 2 just as you did before.

Answer:
values of x that makes the expression true are less than -2/23
Step-by-step explanation:
GIven the expression
23x + 7 ≤5
Subtract 7 from both sides

How do you multiply 14.60 * 870
Answer:
12702
Step-by-step explanation:
Since there are 2 digits after the decimal in 14.60, add a decimal to the 870 and put two 0s after it (So it looks like this 870.00)
Then put the two numbers on top of each other, make sure to line up the decimals and multiply normally. When you're done, you should come out with the number 127020000. Since there is 2 digits behind the first number and 2 digits behind the second number, resulting in 4 digits, you're gonna count 4 numbers from the back of your answer and put a decimal there (so it is now 12702.0000) but you don't really need those 0s there so you can just remove them. (Answer 12702)
Hope this helped. If not, search up "Multiply a Whole Number by a Decimal | Math with Mr. J" it might explain better

Answer:
see below
Step-by-step explanation:
The x-values in each table are evenly-spaced (increasing by 2). So, the quadratic function can be identified by its second differences: they will be a non-zero constant.
Table 1 has first differences that are constant at 3. -2-(-5) = 3, for example. It represents a linear function.
Table 2 has first differences of 4, 8, 4, 4, neither constant, nor linearly increasing. The function does not have a name.
Table 3 has first differences of -9, -3, +3, +9, and these have differences of +6. This represents a quadratic function.
Table 4 has first differences of 0.5, 1, 2, 4. These have a constant ratio, as do the values in the table. It represents an exponential function.
The table that represents a quadratic function is C. Table 3.
What is a quadratic function?A quadratic function simply means a function that's in the form of f(x) = ax² + bx + c.
In this case, the table that represents a quadratic function is table 3. It has first differences of -9, -3, +3, +9, and these have differences of +6. It can be deduced that in the quadratic function, b and x are numbers.

What is a perpendicular bisector notation?
Answer:
In a pyramid, line segment AD is the perpendicular bisector of triangle ABC on line segment BC. If AB = 20 feet and BD= 7 feet, find the length of side AC.
Step-by-step explanation:
Solution
It is given that AD is the perpendicular bisector on the line segment BC.
So, By Perpendicular Bisector Theorem, any point on line segment AD is at an equal distance from points B and C. It implies, AB = AC
AC = 20 feet.
A rectangle has an area of 500 square meters. If it's length is 4x-3 meters and it's width is 2x+6 meters, what is the actual width of the rectangle?
Answer:
25 meters .
Step-by-step explanation:
The actual width of the rectangle is 24.5 meters.
What is area of rectangle?The area of rectangle equals the base(width) times the height.
A = w × h
Given
Area of rectangle = 500 square meters.
Length of rectangle = 4x - 3 meters
Width of rectangle = 2x + 6 meters
Area of rectangle = length × width
500 = (4x - 3) (2x + 6)
⇒ 500 = [tex]8x^{2}+24x-6x-18[/tex]
⇒ 500 = [tex]8x^{2}+18x-18[/tex]
⇒ 500 = [tex]2(4x^{2}+9x-9)[/tex]
⇒ [tex]\frac{500}{2}=4x^{2}+9x-9[/tex]
⇒ [tex]250=4x^{2}+9x-9[/tex]
⇒ [tex]4x^{2}+9x-9-250=0[/tex]
⇒ [tex]4x^{2}+9x-259=0[/tex]
⇒ 4x(x + 7) -37(x + 7) = 0
⇒ (x + 7) (4x - 37) = 0
⇒ x = -7, x = [tex]\frac{37}{4}[/tex]
-7 is not satisfied because it is a negative number.
By substituting x = [tex]\frac{37}{4}[/tex] in width of rectangle
Actual width of rectangle = 2x + 6
= 2( [tex]\frac{37}{4}[/tex]) + 6
= [tex]\frac{37}{2}[/tex] + 6
= [tex]\frac{37+12}{2}[/tex]
= [tex]\frac{49}{2}[/tex]
= 24.5 meters
Hence, the actual width of the rectangle is 24.5 meters.

A silo has a diameter of 50 feet and a height of 30 feet with a cone on top adding another 10 feet of height. What is the volume of the silo.
Answer:
Step-by-step explanation:
Solve this by adding the volume of the cylinder with the volume of the cone. The volume of a cylinder is found from the equation:
pi * r^2 * h
In this case that gives pi * 50^2 * 30 = 75000pi
The area of the cone is found from the equation:
pi * r^2 * h *1/3
In this case you get pi * 50^2 * 10 * 1/3= 8333.pi
Add the two to ger 83333.333*pi ~261799
An exponential relationship has a growth factor of3and y-intercept of 4.Evalute the function that represents the function that represents this relationship where x=10
Answer:
[tex]f(10)= 236196[/tex]
Step-by-step explanation:
Given
[tex](x,y) = (0,4)[/tex] --- y intercept
[tex]b = 3[/tex] --- growth factor
Required
[tex]f(10)[/tex]
An exponential function is represented as:
[tex]y = ab^x[/tex]
[tex](x,y) = (0,4)[/tex] means
[tex]4=a * b^0[/tex]
[tex]4=a *1[/tex]
[tex]a= 4[/tex]
So, we have:
[tex]y = ab^x[/tex]
[tex]y = 4(3)^x[/tex]
or
[tex]f(x)= 4(3)^x[/tex]
When x is 10, the value of the function is:
[tex]f(x)= 4(3)^x[/tex]
[tex]f(10)= 4(3)^{10[/tex]
[tex]f(10)= 236196[/tex]
A survey of 1,076 tourists visiting Orlando was taken. Of those surveyed: 297 tourists had visited LEGOLAND 275 tourists had visited Universal Studios 85 tourists had visited both the Magic Kingdom and LEGOLAND 88 tourists had visited both the Magic Kingdom and Universal Studios 73 tourists had visited both LEGOLAND and Universal Studios 34 tourists had visited all three theme parks 95 tourists did not visit any of these theme parks How many tourists only visited the Magic Kingdom (of these three)
Answer:
129 tourists
Step-by-step explanation:
Let 'A' represent the tourists that visited LEGOLAND, let 'B' represent the tourists that visited Universal Studios, and let 'C' represent the tourists that visited Magic kingdom
The total number of tourists, n = 1,076
The number of tourist surveyed that visited only LEGOLAND = A∩B'∩C' = 297 tourist
The number of tourist that visited only Universal studios, B∩A'∩C' = 275 tourist
The number of tourist that visited both the Magic Kingdom and LEGOLAND, A ∩ B' ∩ C = 85 tourist
The number of tourist that visited both the Magic Kingdom and Universal Studios, A' ∩ C ∩ B = 88 tourists
The number of tourist that visited both the LEGOLAND and Universal Studios, A ∩ B ∩ C' = 73 tourist
The number of tourist that visited all three theme parks, A ∩ B ∩ C = 34 tourist
The number of tourists that did not visit any of these theme parks = 95 tourists
In set theory, we have for three sets
A ∪ B ∪ C = A∩B'∩C' + B∩A'∩C' + C∩A'∩C' + A ∩ B' ∩ C + A' ∩ C ∩ B + A ∩ B ∩ C' + A ∩ B ∩ C
A ∪ B ∪ C = 1,076 - 95 = 981
∴ The number of tourists that only visited Magic Kingdom, 'C∩A'∩C' ', is given as follows;
C∩A'∩C' = A ∪ B ∪ C - (A∩B'∩C' + B∩A'∩C' + A ∩ B' ∩ C + A' ∩ C ∩ B + A ∩ B ∩ C' + A ∩ B ∩ C)
∴ C∩A'∩C' = 981 - (297 + 275 + 85 + 88 + 73 + 34) = 129
The number of tourists that only visited the Magic Kingdom, C∩A'∩C' = 129 tourist
