The amusement park is open for 11 hours if approximately 200 people can ride the swing in one hour what is the maximum amount of people that can ride the swing in one day
Answers
Answer:
2,200
Step-by-step explanation:
Number of hours amusement park opens = 11 hours
Number of people who ride the swing in one hour = approximately 200
what is the maximum amount of people that can ride the swing in one day?
Number of people that can ride the swing in one day = Number of hours amusement park opens × Number of people who ride the swing in one hour
= 11 × 200
= 2,200 approximately
Number of people that can ride the swing in one day = 2,200

Answer:
[tex]x^{2} - 25[/tex]
Step-by-step explanation:
Area is side x side, so naturally it would be: (x+5)(x - 5)... Though to simplify, those parenthesis can be FOILed. (Reminder: "FOIL" means First - Outer - Inner - Last)
[tex]x^{2} - 5x + 5 x - 25[/tex]
The 5x cancels out because 5x - 5x = 0
So that leaves us with:
[tex]x^{2} - 25[/tex]
=========================================================
Explanation:
Let's say we replace the "x+5" with some other letter. Let's use L for length.
We'll keep the width x-5 the same.
area = length*width
area = L*(x-5)
area = L*x + L*(-5)
area = xL - 5L
At this point, we would then plug in L = x+5 and distribute like so:
area = x( L ) - 5( L )
area = x( x+5 ) - 5( x+5 )
area = x^2 + 5x - 5x - 25
area = x^2 - 25
Side note: (x+5)(x-5) = x^2 - 25 is an application of the difference of squares rule.

Step-by-step explanation:
Please be explicit in labeling the radius. I will assume y ou meant r = 13 m.
Circumference formula: C = 2πr; area formula: A = πr²
Here, with r = 13 m, C = 2π(13 m) = 26π m = C = 81.68 m

A car wheel has a diameter of 27.1". How far will the car go when the wheels rotate 100 times?
Answers
Answer:
135.5"
Step-by-step explanation:
Answer:
8509.4
Step-by-step explanation:
The diameter has already been displayed so what I could simply do is solve the equation simply by using the formula for circumference using diameter (C=3.14 x 27.1) and that will get me 85.094 but thats how far it will get if it rotates 1 times so we must multiply it by 100 and move the decimal point 2 digits to the right and the final answer is 8509.4. 8509.4 (no mathematical unit) is how far the car can go when the wheels have a diameter of 27.1 and rotates 100 times.The composite figure is made up of a cone and a half sphere.

A half sphere and cylinder. Both have a radius of 6 centimeters. The cone has a height of 12 centimeters.
Recall the formulas V = one-third B h and V = four-thirds pi r cubed

489.84 cubic centimeters
904.32 cubic centimeters
1,356.48 cubic centimeters
Answers
Given:
Radius of half sphere and cone = 6 cm
Height of cone = 12 cm
To find:
The volume of composite figure that is made up of a cone and a half sphere.
Solution:
Volume of half sphere is:
[tex]V_1=\dfrac{2}{3}\pi r^3[/tex]
Where r is the radius of the half sphere.
Putting [tex]\pi =3.14, r=6[/tex], we get
[tex]V_1=\dfrac{2}{3}(3.14)(6)^3[/tex]
[tex]V_1=\dfrac{6.28}{3}(216)[/tex]
[tex]V_1=452.16[/tex]
Volume of a cone is:
[tex]V_2=\pi r^2h[/tex]
Where r is the radius and h is the height of the cone.
Putting [tex]\pi =3.14, r=6, h=12[/tex], we get
[tex]V_2=(3.14)(6)^2(12)[/tex]
[tex]V_2=(3.14)(36)(12)[/tex]
[tex]V_2=1356.48[/tex]
Volume of the composite figure is:
[tex]V=V_1+V_2[/tex]
[tex]V=452.16+1356.48[/tex]
[tex]V=1808.64[/tex]
Therefore, the volume of a composite figure is 1808.64 cubic centimetres.
Note: All options are incorrect.

Answer:

Step-by-step explanation:
The first 4 digits are simple, you multiply the first digit of the equation by the 2nd digit and then for the other 2 you multiply the first digit of the equation by the 3rd digit.
6 + 2 + 8
6 * 2 = 12
6 * 8 = 48
Then the last 2 digits are the sum of the products of the 1 and 2 and 1 and 3 and subtract it by the 2
12 + 48 = 60
60 - 2 = 58

From the question we are told that:
The Equation
[tex]\frac{x^2}{9}*\frac{y^2}{25}[/tex]
Generally
From the Equation
[tex]a^2=25[/tex]
[tex]a=5\\b^2=9\\b=3[/tex]
Therefore
[tex]c=\sqrt{a^2-b^2}[/tex]
[tex]c=\sqrt{25-9}[/tex]

[tex]C=(0,0)[/tex]
Generally the equation for foci is mathematically given by
[tex]F=(h,k \pm c,0)[/tex]

A typical student from this group spends more than 10 hours watching television each week.
More students watch 3 hours of television than watch more than 3 hours of television.
All students watch 20 or fewer hours of television each week.
The most common answer for the number of hours that a student watches per week was 3.
Answers
Answer:
Part A
False
Part B
True
Part C
True
Part D
True
Step-by-step explanation:
A scatter diagram created with MS Excel shows the data as on the dot plot in a similar question obtained online
The number of students in the group = 92
Part A
The number of students that spend more than 10 hours watching television = 39
Therefore, given that less than half of the student spend more than 10 hours watching television, the statement is false
Part B
The number of students that watch 3 hours of television is the highest than any other time range with 16 students, therefore, the statement is true
Part C
The maximum hours watched by a student in the dot plot is 20 hours, therefore, the statement is true
Part D
The number of hours for which the student watched and which has the highest frequency is 3 hours, therefore, the statement is true as more students have 3 hours as the number of hours watched (16 students) than any other number of hours
