A health club charges $250 to become a member and an additional $25 per month. Assuming no other charges, what is the total cost of the first full membership
Answers
Answer:
$275
Step-by-step explanation:
I am 100% sure that $275 would be for the first cost of the month. if its monthly then you times that by 12 to get 3,300 which would be the cost for the year.
That’s the answer because:
This problem can be made into
25x+250
Where x is the number of months
So if they stayed for a month it would be
25(1)+250
25*1 is 25

Use traces to sketch the surface. x2 = y2 + 5z2
Answers
Answer:
when k > 0 the traces parallel to the yz plane is an ellipse
The traces parallel to the xz plane are parabolas and they open in positive x- axis direction
The traces parallel to the xy plane are parabolas that open in the positive x-axis direction
Step-by-step explanation:
Given surface : [tex]x^2 = y^2 + 5z^2[/tex]
To determine the traces of the given equation we will have to make some assumptions and the assumption is
let x = k
[tex]k^2 = y^2 + 5z^2[/tex]
when k > 0 the traces parallel to the yz plane is an ellipse
let y = k
[tex]x^2 = k^2 + 5z^2[/tex]
The traces parallel to the xz plane are parabolas and they open in positive x- axis direction
Let z = k
[tex]x^2 = y^2 + 5k^2[/tex]
The traces parallel to the xy plane are parabolas that open in the positive x-axis direction
with the given traces The surface can be sketched

Answer:
80.4
Step-by-step explanation:
You have to first find the area of the circle which the formula for that is pi r^2. So you would set it up as 3.14 (2.5)^2 which you then would solve and get 19.625. Then, you find the area of the square which is length times width. So then you would multiply 10 and 10 and get 100. You then subtract 100 and 19.625 which gives you 80.375 but since it says round to the nearest tenth you'd get 80.4.
Step-by-step explanation:
For no.1
sloution,

[tex]r = 2.5[/tex]
[tex]\pi = 3.14[/tex]
Area(A1)=?
now,
A = π r²

A=19.6
A1=19.6cm^2

now,
A=L^2

A=100-19.6
A=80.4cm^2

Tyler claims that because he started painting first he will finish painting his side of the fence before Benito finishes painting his side. Is this true? Explain
Answers
Answer:
but
Step-by-step explanation:
yrge sksue dnd djd d d. r e g g h a s. v j u r d. d c g y t
Tyler's claim about finishing his painting first is False because it will take Benito 10 minutes while Tyler will require over 11 minutes to finish up his painting despite starting before Benito.
Size of fence = 150 feet
Benito's rate = 15 ft/min
Tyler's rate = 11 ft/ min
Size already painted by Tyler when Benito started = 39/2 = 19.5 ft
Portion of fence left for Tyler to paint when Benito started = (150 - 19.5) = 130.5 feets
Time required for Tyler to finish :
Time required = 130.5 ÷ 11 = 11.863 minutes
Time required for Benito to finish :
Time required = 150 ÷ 15 = 10 minutes
Time required for Benito to complete his painting is lesser than Tyler's (10 < 11.863)
Hence, Tyler's claim is False

Answer:
The area of the rectangle is 324 square centimeter.
Step-by-step explanation:
What is area?
The area is the amount of space within the perimeter of a 2D shape.
What is rectangle?
A rectangle is a two-dimensional shape (2D shape) in which the opposite sides are parallel and equal to each other and all four angles are right angles.
What is perimeter?
Perimeter is the distance around the edge of a shape.
Let the width of the rectangle be x cm.
Then, the length of the rectangle = 4xcm
Perimeter = 2(length + breadth )
90 = 2(4x+x)
90 = 2*5x
90 = 10x
x = 90/10= 9cm
Width = 9cm
Length = 4*9 = 36 cm
Area = Length*Breadth
=9*36
=324 square centimeter.

A study is conducted to assess the smoking behaviors of high-school seniors. A random sample of 8 seniors is selected and each student is asked the number of cigarettes consumed on a typical day. The (sorted) sample is: 0 0 3 4 5 8 10 18. If 18 is replaced with 20, then select all that apply:
Sample IQR will change
Range, IQR, and standard deviation will remain the same
Sample range will change.
Sample standard deviation will change
Answer:
Sample range will change
Sample Standard deviation will change
Step-by-step explanation:
Given the sorted sample : 0,0,3, 4,5,8,10, 18
n = number of observations
Sample range : ( 18 - 0) = 10
Upper quartile (Q3) = 3/4(n+ 1) = 3/4(9) th term
Q3 = 27/4 = 6.75th term
(8 + 10) / 2 = 18/ 2 = 9
Lower quartile (Q1) = 1/4(n + 1) = 9/4 th term
2.25th term = 0+3 = 3/2 = 1.5
Interquartile range = 9 - 1.5 = 7.5
Standard deviation = 5.976 (using calculator)
If 18 is replaced by 20:
0,0,3, 4,5,8,10, 20
Range = (20 - 0). = 20
Upper quartile (Q3) = 3/4(n+ 1) = 3/4(9) th term
Q3 = 27/4 = 6.75th term
(8 + 10) / 2 = 18/ 2 = 9
Lower quartile (Q1) = 1/4(n + 1) = 9/4 th term
2.25th term = 0+3 = 3/2 = 1.5
Interquartile range = 9 - 1.5 = 7.5
Standard deviation = 6.563 (using calculator)
