Answer:
x=10.7, y=11300
Step-by-step explanation:
x%of 31 = 3.317
x/100×31=3.317
31x/100=3.317
31x= 3.317×100
x= 3.317 ×100/31
x =10.7
4407= 39% of y
4407= 39/100 × y
4407 =39y/100
4407×100=39y
4407 × 100/39=y

A cone has a slant height of 7.5cm and a radius of 4.5 cm. What is the volume of the cone?
Now
volume:-
1/3πr²h1/3π(4.5)²(6)π(20.25)(2)40.5πcm³Answer:
Volume of cone = 127.17 cm³Step-by-step explanation:
In the question we are given ,
Slant height = 7.5 cmRadius = 4.5 cmAnd we are asked to find the volume of cone. We know that ,
[tex] \red{\boxed{ \rm{Volume \: of \: cone = \frac{1}{3} \pi r {}^{2}h }}}[/tex]
Where ,
π = 3.14r = 4.5 cmh = Not givenSo , for finding volume of cone we must have to find the height of cone using slant height formula i.e. ,
[tex] \green{\boxed{ \sf{l {}^{2} = h {}^{2} + r {}^{2} }}}[/tex]
Where ,
l = slant heighth = heightr = radiusNow , substituting values :
[tex] \hookrightarrow \: 7.5 {}^{2} = h {}^{2} + 4.5 {}^{2} [/tex]
Transposing 4.5 to left hand side :
[tex] \hookrightarrow \: 7.5 {}^{2} - 4.5 {}^{2} = h {}^{2} [/tex]
[tex] \hookrightarrow \:56.25 - 20.25 = h {}^{2} [/tex]
On further calculations we get :
[tex] \hookrightarrow \:h {}^{2} = 36[/tex]
[tex] \hookrightarrow \:h = \sqrt{36} [/tex]
We know that 6 × 6 is equal to 36 that means square root of 36 is 6 . So :
[tex] \hookrightarrow \pink{\boxed{\bold{h = 6 \: cm}}}[/tex]
Therefore, height of cylinder is 6 cm .Now finding volume :Substituting values in volume formula :
[tex] \longrightarrow\: \frac{1}{ \cancel{3} } \times 3.14 \times (4.5) {}^{2} \times \cancel{6}[/tex]
Step 1 : By cancelling 6 with 3 we get :
[tex] \longrightarrow \: 3.14 \times 20.25 \times 2[/tex]
Step 2 : Multiplying 20.25 with 2 :
[tex] \longrightarrow \:3.14 \times 40.50[/tex]
Step 3 : Multiplying 3.14 with 40.50 :
[tex] \longrightarrow \: \purple{\boxed{\bold{127.17 \: cm {}^{3} }}}[/tex]
Therefore, volume of cone is 127.17 cm³ .#Keep LearningA normal deck of 52 cards includes 4 suits where each suit ranges from 2 though 10 inclusive, Jack, Queen, King and Ace.

Answer: It would be A
Step-by-step explanation:
First: Find Median
18,19,|19|,20,|20,20|,21,|22|,22,26
there is 10 numbers so it would be between 20 and 20. Add 20 and 20 and you will get 40 and divide by 2 to get 20. Your median is 20 and the dot should be on top of the 20.
Second: Find Quartile 1 and 3
Since it’s 5 numbers on each side, the math is friendly. So you count the first 2, then circle the next number and count the last 2. The one you circled is your Quartile 1 and do the same for Quartile 3. Q1 should be 19 and Q3 should be 22. Check if they are underneath that number you got.
Last: now you know that you just have to find the median and the Q1 and Q3 and you should get the answer which is A.

help! how do i find the slope and the y-intercept? please help
Answer:
1 is the - Slope
4 is the y-intercept
Step-by-step explanation:
To find slope, you have to use two points and use the formula [tex]\frac{y2-y1}{x2-x1}[/tex]
Here one point is (2,6), and other point is (4,8)
Substitute to get [tex]\frac{2}{2}[/tex] which equals 1.
To find y-intercept, x should be 0. If x is 0 then why in this case would be 4

Given :-We have given one rectangle whose 3 by 4th part is shaded and remaining part is non shaded. To Find :- We have to find the area of shaded region of the given figure .Let's Begin :-Here, We have
The dimensions of large rectangle as 12 units and 8 units That is, [tex]\sf{ Length = 9 + 3 = 12 \: units}[/tex][tex]\sf{ Breath = 4 + 4 = 8 \: units}[/tex]The dimensions of non shaded rectangles are 9 units and 4 unitsWe know that,
Area of rectangle
[tex]\bold{\red{ = Length {\times} Breath }}[/tex]
Subsitute the required values,
Area of large rectangle
[tex]\sf{ = 12 {\times} 8 }[/tex]
[tex]\sf{ = 96 \:units^{2}}[/tex]
Thus, The area of large rectangle is 96 units² .
Now,Area of non - shaded rectangle
[tex]\sf{ = 9 {\times} 4 }[/tex]
[tex]\sf{ = 36\: units^{2}}[/tex]
Thus, The area of non shaded rectangle is 36 units² .
Therefore,Area of shaded region
= Area of large rectangle - Area of non shaded rectangle
Subsitute the required values,
[tex]\sf{ = 96 - 36}[/tex]
[tex]\sf{ = 60\: units^{2}}[/tex]
Hence, The total area of shaded region is 60 sq.units.
➾Length(L) of bigger rectangle = [tex]\sf{9+3\: =\:12}[/tex]units.
➾Length(l) of smaller rectangle = 9units.
➾Breadth (B) of bigger rectangle = [tex]\sf{4+4 \:=\: 8}[/tex]units.
➾Breadth(b) of smaller rectangle = 4 units.
✰To Find:-➾Area of the shaded region.
✰Solution:-➾We can find the area of shaded region by subtracting area of smaller rectangle from area of bigger rectangle(that is whole rectangle including shaded and non shaded region).
So,
➾Area of bigger rectangle = [tex]\sf{L×B}[/tex](putting the value of L and B from the above given)
= [tex]\sf{8×12}[/tex]
= [tex]\sf{96unit^2}[/tex]
Similarly,
➾Area of smaller rectangle = [tex]\sf{l×b}[/tex](putting the value of l and b from the above given)
= [tex]\sf{9×4}[/tex]
= [tex]\sf{36unit^2}[/tex]
Now,
➾Area of shaded region = Area of bigger rectangle - Area of smaller rectangle.
[tex]\sf{= 96-36}[/tex]
[tex]\sf{= 60unit^2.}[/tex]
Therefore, area of shaded region[tex]\sf{= 60unit^2.}[/tex]

C. Divide 99 by 479.
9
D. Divide 99 by 204.
Answer:
A
Step-by-step explanation:
I didn't learn jrf, but I believe that it is the amount of females that watch action movies divided by the total amount of females.
Amount of females who watch action movies= 99
Total females= 250
So, A seems correct.
The joint relative frequency of being male and attending a drama film, divide 124 by 229.
What is Relative Frequency?The number of times an event occurs divided by the total number of events occurring in a particular scenario is described as relative frequency.
Two things must be understood in order to compute the relative frequency:
Total number of events/trialsA category or subgroup's frequency countAction Drama Total
Male 105 124 229
Female 99 151 250
Total 204 275 479
The joint relative frequency is the frequency in a given category divided by the total number of data values.
Here, The total number of males = 229
and, the number of males that like drama = 124
To calculate the joint relative frequency of being male and attending a drama film, divide 124 by 229.

Step-by-step explanation:
The answers to the questions are given below.
What is a expression? What is a mathematical equation? What is the volume of a cube and a prism?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. The volume of a cube is - [V] = a x a x awhere [a] is side length of cube.
The volume of a prism is -[V] = [h] × [w] × [L]where [h] is prism height, [w] is its width, and [L] is its length.
We have the question as shown in the figure.
Cube with side length (1/5) :
Volume = (1/5 x 1/5 x 1/5) = 1/125 cm³
Prism of dimensions (L = 1/5, B = 2/5, H = 3/5) :
Volume = (1/5 x 2/5 x 3/5) = 6/125 cm³
Cube with side length (2/5) :
Volume = (2/5 x 2/5 x 2/5) = 8/125 cm³
Prism of dimensions (L = 3/5, B = 4/5, H = 3/5) :
Volume = (3/5 x 4/5 x 3/5) = 36/125 cm³

Answer :

Step-by-step explanation :
⠀
We know that,

⠀
Here,
r is the radius of the circle.We'll take the value of π as 3.14 . (Answer may be different if we take the value of it as 22/7)⠀
Now, substituting the values :
⠀
[tex]{\longrightarrow \qquad \sf{ 2 \times 3.14 \times r = 122}}[/tex]
