Answer: 20 feet
Step-by-step explanation:
This represents a right angled triangle with the length of the slide being the hypotenuse, the height of the ladder being the height of the triangle and the distance from the base of the ladder being the length.
Solve with Pythagoras rule:
c² = a² + b²
c = hypotenuse
a= length
b = height
29² = 21² + b²
841 = 441 + b²
b² = 841 - 441
b² = 400
b = √400
b = 20 feet

5 numbers :
mode = n median= n+1 mean = n+2 Range = n+3
find 2 sets of numbers
Answer:
3,3,4,6,6
4,4,5,6,7
5,5,6,6,8
Step-by-step explanation:
mode = n
median= n+1
mean = n+2
Range = n+3
let sets:
a,b,c,d,e
mode = n, at least two of them are the same and equal to n
n,n,c,d,e
median belong to the set, in ascending order:
n,n,n+1,d,e
which means d,e ≥ n+1, d≠e
mean is n+2
5(n+2)=n+n+n+1+d+e
2n+9=d+e
Assume e is the maximum:
Range is n+3:
e-n=n+3
e=2n+3
d=6≥n+1
n≤5,
Set is n,n,n+1,6,n+3
n+1≤6≤n+3

Greta has budgeted $1,500 to have a concrete patio poured in her backyard like the one shown. The cost per square foot of the concrete is $5.50. Find the cost of the patio to determine if Greta has budgeted enough money to complete the project.
Answer:
Yes the amount Greta has budgeted ($1,500) is enough to complete the project which will cost $1,443.75
Step-by-step explanation:
The amount Greta has budgeted to have a concrete patio = $1,500
The cost (per square foot) of the concrete, C/Ft² = $5.50/ft²
From the dimension of the backyard, we have;
The total area, A = The area of a rectangle + The area of a trapezium
The area of the rectangle = 6 ft. × 28 ft. = 168 ft.²
The area of the trapezium = (8 ft. + (28 ft. - 15 ft.))/2 × (15 ft. - 6 ft.) = ((8 ft. + 13 ft.)/2) × 9 ft. = 94.5 ft.²
The total area, A = 168 ft.² + 94.5 ft.² = 262.5 ft.²
The total cost of the concrete, C = A × C/Ft²
∴ C = 262.5 ft.² × $5.50/ft² = $1,443.75
Therefore, given that Greta budgeted $1,500 for the project which is more than the $1,443.75 required, Greta has budgeted enough money to complete the project

2. 3x = у у= 2х + 2 2
Answer:
Step-by-step explanation:
3x = y ------------(I)
y = 2x + 22 ---------------(II)
Substitute y = 2x + 22 in equation (I)
3x = 2x + 22 {Subtract 2x form both sides}
3x -2x = 22
x = 22
Plugin x = 22 in equation (I)
3*22 = y
y = 66
Answer:
Step-by-step explanation:
3x = y
y = 2x + 22
3x = 2x + 22
3x -2x = 22
x = 22
3x22 = y
66=y

Answer:
131°
Step-by-step explanation:
to find the total degrees of this polygon, we use the equation
=> n - 2 × 180° (n= number of sides)
5 - 2 × 180° = 540°
now by using angle sum property,
540° = 80° + 148° + 81° + 100° + [tex]x[/tex]°
540° = 409° + [tex]x[/tex]°
[tex]x[/tex]° = 540° - 409°

Answer:
the third one
Step-by-step explanation:
bc like there are 2 boxes of 1 and 5 boxes of 1/6 so thats already 2 and 5/6 which applies to all of them. then there is 1 box of 1 and 2 boxes of 1/3 so thats 1 and 1/3 which applies to all of them also but when you make them have the same denominator you get 2 and 5/6 + 1 and 4/6 which deletes the second one. When you add you should get the same denominator so that deletes the first one so then you simplify that and the fraction should still be equal to the unsimplified fraction so you should get 4 and 1/2 if that makes sense

In this scatterplot, the horizontal axis indicates years
since 2000 and the vertical axis indicates the population
of a pack of wolves. The equation of a trend line is also
given. Use it to predict the population in 2016.
11
Answer:
Population of wolves in 2016 = 23
Step-by-step explanation:
Equation of the line of best fit has been given as,
y = 1.5x - 1
Here, y = population of a pack of wolves
x = duration (in years) since year 2000
Duration between year 2000 and 2016 = 16 years
Now we substitute the value x = 16 in the equation of line of best fit,
y = 1.5(16) - 1
y = 24 - 1
y = 23
Therefore, population of wolves in 2016 = 23

Avannah needs to buy a bag of dog food that will last for 2 weeks (14 days). She estimates that a 20 lb bag will be enough. Is she correct?
Answer:
Yes, she is correct.
Step-by-step explanation:
In the question it is given that Avannah wants to buy food for her dog that may lasts for 2 weeks (or 14 days). Dogs must serve food according to their breed and their weight. The diet of every dog is different. Avannah needs to feed her dog three times a day. So a 20 lb bag of food is enough for her to feed her dog for 2 weeks.
So it is the correct decision to get a 20 lb bag of food for her dog. It will last for 14 days.
Line segment XY is located at X(2, 6) and Y(4,8). If the line segments is dilated by a scale factor of 2 with a center of dilation of T(-3, 4). What are the coordinates of X'?
Given:
Line segment XY is located at X(2, 6) and Y(4,8).
The line segments is dilated by a scale factor of 2 with a center of dilation of T(-3, 4).
To find:
The coordinates of X'
Solution:
If a figure dilated by a scale factor k with a center of dilation (a,b), then the rule of dilation is:
[tex](x,y)\to (k(x-a)+a,k(y-b)+b)[/tex]
The line segments is dilated by a scale factor of 2 with a center of dilation of T(-3, 4). So, the rule of dilation is
[tex](x,y)\to (2(x-(-3))+(-3),2(y-4)+4)[/tex]
[tex](x,y)\to (2(x+3)-3,2y+2(-4)+4)[/tex]
[tex](x,y)\to (2x+6-3,2y-8+4)[/tex]
[tex](x,y)\to (2x+3,2y-4)[/tex]
The coordinate of X are (2,6).
[tex]X(2,6)\to X'(2(2)+3,2(6)-4)[/tex]
[tex]X(2,6)\to X'(4+3,12-4)[/tex]
[tex]X(2,6)\to X'(7,8)[/tex]
Therefore, the coordinates of X' are (7,8).
The formula P = a + b + c gives the perimeter P of a triangle with side lengths a, b, and c. How much greater is the perimeter of a triangular field with sides that measure 92 yards, 95 yards, and 84 yards than the perimeter of a triangular field with sides that measure 85 yards, 90 yards, and 56 yards?
Answer:
40 yards greater
Step-by-step explanation:
Perimeter of a triangle, P = a + b + c
perimeter of a triangular field with sides that measure 92 yards, 95 yards, and 84 yard
P = a + b + c
= (92 + 95 + 84) yards
= 271 yards
perimeter of a triangular field with sides that measure 85 yards, 90 yards, and 56 yards
P = a + b + c
= (85 + 90 + 56) yards
= 231 yards
perimeter of a triangular field with sides that measure 92 yards, 95 yards, and 84 yard is 40 YARDS GREATER than perimeter of a triangular field with sides that measure 85 yards, 90 yards, and 56 yards

How to write algebraic expression?Algebraic expression are the expression which consist the variables, coefficients of variables and constants.
The algebraic expression are used to represent the general problem in the mathematical way to solve them.
Steps to write down the simple algebraic expression-
Identify all the factors of the expression.Assume a variable for the changing values.Put a coefficient for the variable, if there is any rate of change of variable.Use constant numbers for the fixed values.a. Give 2 input-output pairs that represent this function.
There is total 25 cent is 1 quarter. Thus, when if there are 2 quarters, then the value of cent is 50 and when there are 4 quarters, then the value of cents is 100 cents.
Hence, the two pairs should be as,
(2, 50), (4, 100)
b. Write an equation that represents this function.As, v is the value of quarters in cents. There is total 25 cent is 1 quarter. The total quarter is n. Thus, the function can be given as,
[tex]v(n)=25\times n\rm \;\;cents[/tex]
c. Find the output when the input is 10.Put the value 10 on the place of n in the above equation as,
[tex]v(10)=25\times (10)\\v(10)=250\rm cents[/tex]
The output when the input is 10 is 250 cents.
d. Identify the independent and dependent variables.The independent value is the number of quarters and the dependent variable is the value of cents.
Hence, the independent value is the number of quarters and the dependent variable is the value of cents and the equation that represents this function is,
[tex]v(n)=25\times n\rm \;\;cents[/tex]
