A cylinder and a cone have the same volume. The cylinder has radius x and height y . The cone has radius 1/2x . Find the height of the cone in terms of y .
Answer:
height = 1/4y
Step-by-step explanation:
V(cylinder) = πr²h
V(cone) = πr²h ÷ 3
V(cyl) = πx²y
V(cone) = π(1/2x)²y which simplifies to be πx²y ÷ 4
πx²y = πx²y ÷ 4
if you divide each side by πx² you get:
y = y/4
height is 1/4y
The price of petrol increased from Rs 48 to rs 53.76.
calculate the percentage increase.
with calculation and the answer should be 12%
Answer:
12%
Step-by-step explanation:
As per the provided information in the given question, we have :
Original price of petrol = Rs. 48New price of petrol = Rs. 53.76We are asked to calculate,
Percentage increaseAs we know that,
[tex] \\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{Price \; increase}{Original \; price} \times 100 \Bigg ) \; \%}} \\ [/tex]
→ Price increase = New price - Original price
→ Price increase = Rs. ( 53.76 - 48 )
→ Price increase = Rs. 5.76
Substituting values,
[tex] \\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{5.76}{48} \times 100 \Bigg ) \; \%}} \\ [/tex]
[tex] \\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{576}{4800} \times 100 \Bigg ) \; \%}} \\ [/tex]
[tex] \\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{57600}{4800} \Bigg ) \; \%}} \\ [/tex]
[tex] \\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{576}{48} \Bigg ) \; \%}} \\ [/tex]
[tex] \\ \longrightarrow \bf{\quad\underline { \% \; increase = 12\; \%}} \\ [/tex]
Therefore, percentage increase is 12 %.

A line, y = mx + b. passes through the point (2, 4) and is parallel to y = 3x - 5. What is the value of b?
Answer:
-2
Step-by-step explanation:
Well since this line is parallel to y=3x-5 they must have the same slope
We are just solving for the y-intercept
We have a point (2,4) lets plug it into
y=3x+ b
4 = 3(2) +b
4= 6 +b
-2 = b
The value of b is -2
Answer:
B-value = -2
Step-by-step explanation:
In the picture below Orange line represents the line of "y = 3x - 5", since we know that the line passing through the point (2,4) is parallel to the given line, the slope of the line would be 3x as well. To find b-value or y-intercept we have to plot the point on the graph where the line passing through the points (2,4) intersects the y-axis, in this case it's at (0,-2), therefore the b-value = -2.
Hope this helps!
Here is the diagram:
the only solution to x² + bx + c = 0
is x = 5
work out the values of b and c
Answers:
b = -10
c = 25
=================================================
Explanation:
If x = 5 is the only solution then (x-5) is the only factor. Turns out we have repeated solutions and repeated factors. Meaning (x-5)(x-5) = (x-5)^2 is what we're after.
Expand that out to get
(x-5)^2
x^2 - 5x - 5x + 25
x^2 - 10x + 25
Then compare this to x^2 + bx + c to find
b = -10
c = 25
If you were to solve x^2-10x+25 = 0, you'll find that x = 5 is the only root.

The set of all values that a function will return as outputs is called the _________ of the function.
Answer:
Range.
Step-by-step explanation:
In Computer programming, a variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited.
Basically, variable stores information which is passed from the location of the method call directly to the method that is called by the program.
For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function. Therefore, when you create variables in a function, you can can set the values for their parameters.
Furthermore, the set of all values that a function will return as outputs is called the range of the function.
This ultimately implies that, the range of a function is simply a complete set of possible values that are generated from a dependent variable after a domain has been substituted. Thus, a range is the resulting values from a data set when all the possible input values have been substituted.
Please rate your understanding of the vocabulary from today (planes, points, lines, collinear, coplanar, line segments, rays, and opposite rays.) I understand the definitions of all terms above and I could explain these topics to others. 4 I am not sure if I understand every word completely, but I have enough confidence to try and figure it out. 3 Some terms make sense, but I need some help understanding others. 2 This is new to me and I cannot define these terms now. 1
Answer:
See below
Step-by-step explanation:
A plane is a flat, two-dimensional surface that extends infinitely.
A point is a precise location on a plane.
A line is a one-dimensional figure that has only its length that extends infinitely.
Points are collinear if they all fall on the same straight line.
Points or lines are coplanar if they all fall on the same plane.
Line segments are a line with two endpoints on each end of the segment, which have a definite length.
Rays are lines that have one endpoint and the other end of the line extends infinitely with no endpoint.
Opposite rays are two rays that have a common endpoint that point in opposite directions and form a straight line.

नाफा (P%)=5
विक्रय मुल्य =?
Answer:
विक्रय मुल्य=रु.63000
Step-by-step explanation:
खरिद मुल्य)- रु. 60,000 (cp)
नाफा (P%)=5 (p%)
विक्रय मुल्य =? (sp)
now,
sp=(100+p%)/100×cp
(100+5)/100×6000063000so, sp is Rs 63000.

Please help me, I’ve literally been trying for so long.
Let the cosecutive numbers be like this :
2n + 1 , 2n + 2 , 2n + 3 , 2n + 4 , 2n + 5
Odd , Even , Odd , Even , Odd
______________________________
So we have :
(2n+1)+(2n+3)+(2n+5)=(2n+2)+(2n+4) + 39
6n + 9 = 4n + 6 + 39
6n + 9 = 4n + 45
Subtract both sides 9
6n + 9 - 9 = 4n + 45 - 9
6n + 0 = 4n + 36
6n = 4n + 36
Subtract both sides 4n
6n - 4n = 4n - 4n + 36
2n = 0 + 36
2n = 36
Divide both sides by 2
2n ÷ 2 = 36 ÷ 2
n = 18
______________________________
So the numbers are :
2(18)+1 , 2(18)+2 , 2(18)+3 , 2(18)+4 , 2(18)+5
36 + 1 , 36 + 2 , 36 + 3 , 36 + 4 , 36 + 5
37 , 38 , 39 , 40 , 41
As u can see the Odd numbers are :
37 , 39 , 41

If sin 0= 4/5 in quadrant II, what is cose? A. - 3/5 B. 3/5 C. - 3/4 D. 3/4
Answer:
A
Step-by-step explanation:
Given
sinθ = [tex]\frac{4}{5}[/tex] = [tex]\frac{opposite}{hypotenuse}[/tex]
This is a 3- 4- 5 triangle
with opposite = 4, adjacent = 3 and hypotenuse = 5
Since θ is in second quadrant then cosθ < 0
cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex] = - [tex]\frac{3}{5}[/tex] → A

Lily is in charge of bringing bottled water to a party that has 37 guests.
Bottled water is sold in packs of 36 and each pack costs $42.12.
Part A: enter the total number of packs of water Lily will need to bring to the party if each guest is to have 3 bottles of
water.
Part B: enter the total cost, in dollars, Lily will spend on bottled water for the party.
Answer:
A) 4 packs
B) $168.48
Step-by-step explanation:
A) Lily will need to bring 4 packs of bottled water because 3 bottles per guest is 37 times 3, which gives us 111 water bottles. If each pack has 36, divide 111 water bottles by 36 giving us 3.08333333333 packs. Since you cannot buy 3.08333333333 packs of bottled water, Lily will need to round up to the nearest whole number to insure that each guest has exactly 3 water bottles. When you round up it will be 4 packs of bottled water.
B) Because Lily is bringing 4 packs of bottled water to the party and each pack costs $42.12, multiply 42.12 by 4 to get $168.48 as the total cost of her purchase.
