Any one can help with this Venn Diagram question?.Please note that there is an another language, ignore except if you can understand it.
Answer:
(i) 30
(ii) 8
Step-by-step explanation:
Start by drawing 3 rings for the Venn diagram. Each ring represents either Audi, BMW, or Citroën.
Next, add the information provided in the problem statement. We know that 20 choose BMW only. Another 20 choose Citroën only.
We know the number who choose all 3 is the same as the number that choose BMW and Citroën, but not Audi. We'll call this number x.
Similarly, we know that the number who choose all 3 is half of those choose Audi and BMW, but not Citroën. So we'll say that number is 2x.
We know the total number of Audi votes is 48, the total number of BMW votes is 36, and the total number of Citroën votes is 34.
Finally, we know the total number of voters is 100, including those who voted for no favorites (we'll call that number n).
We know that BMW got 36 votes, so:
20 + x + x + 2x = 36
20 + 4x = 36
4x = 16
x = 4
We know that Citroën got 34 votes, so:
20 + x + x + z = 34
20 + 4 + 4 + z = 34
28 + z = 34
z = 6
We know that Audi got 48 votes:
y + 2x + x + z = 48
y + 2(4) + 4 + 6 = 48
y + 18 = 48
y = 30
Finally, we know that the total number of voters is 100.
20 + 20 + x + x + 2x + y + z + n = 100
20 + 20 + 4 + 4 + 2(4) + 30 + 6 + n = 100
92 + n = 100
n = 8
The angles of a triangle add up to 180 degrees.
The second angle is 15 degrees larger than the smallest angle.
The third angle is 3 times as big as the smallest angle.
Find the measure of the smallest angle (in degrees)
Answer:
33°
Step-by-step explanation:
We were given that:
1- The angles of a triangle add up to 180 degrees
2- The second angle is 15 degrees larger than the smallest angle
3- The third angle is 3 times as big as the smallest angle
So, first of all, let's call the smallest angle x.
the second angle will be (x + 15°) since it is 15 degrees greater than the smallest angle
and the third will be 3x, since it is 3 times bigger than the smallest angle.
With the information we have, we can form an equation!
180° = x + (x+ 15°) + 3x
180° = 5x + 15°
180° - 15° = 5x + 15° - 15°
165° = 5x
165°/5 = 5x/5
33° = x
therefore, the smallest angle measures 33° degrees, the second angle measures 48° and the third angle measures 99°.
99° + 33° + 48° = 180°
so it is safe to say this answer is correct!
If the angles of a triangle add up to 180 degrees. The second angle is 15 degrees larger than the smallest angle. The third angle is 3 times as big as the smallest angle then 35 degree is the measure of the smallest angle.
The sum of three angles is 180 degrees
Let the smallest angle be x
The second angle is 15 degrees larger than the smallest angle.
The third angle is 3 times as big as the smallest angle.
We need to find smallest angle.
What is angle sum property of triangle?The sum of three angles of a triangle is 180 degrees
Let the smallest angle be x
The second angle is 15 degrees larger than the smallest angle.
The third angle is 3 times as big as the smallest angle.
We need to find smallest angle x=?
x+(x+15)+3x=180
2x+15+3x=180
5x+15=180
5x=165
Divide both sides by 5.
x=35
Therefore the smallest angle is 35 degree.

Ali and Steve share some sweets in the ratio 2:7
Steve gets 30 more sweets than Ali.
Work out how many sweets Steve gets.
Answer:
Step-by-step explanation:Let Ali's number of sweets be x
so let Steve's number of sweet be x + 30
hence the equation is x/(x + 30)= 2/7
or, 7x = 2(x + 30)
or, 7x= 2x +60
or,7x-2x=60
or, 5x=60
or, x=60/5
or, x=12
Alif gets 12 sweets
x+30

At the north campus of a performing arts school, 20% of the students are music majors. At the south campus, 70% of the students are music majors. The campuses are merged into one east campus. If 30% of the 1000 students at the east campus are music majors, how many students did the north and south campuses have before the merger?
Answer:
The north campus had [tex]800[/tex] while the south campus had [tex]200[/tex].
Step-by-step explanation:
The question stated that there are [tex]1000[/tex] students in the merged campus. That's the sum of the number of students in the north and the south campus before the merger.
Let [tex]x[/tex] denote the number of students in the north campus before the merger. The other [tex](1000 -x)[/tex] students would all belong to the south campus before the merger.
Before the merger, [tex]20\%[/tex] of the students of the north campus are of music majors. In terms of [tex]x[/tex], that's [tex](20\%)\cdot x = 0.20\,x[/tex] students.
On the other hand, [tex]70\%[/tex] of the students of the south campus are of music majors. That corresponds to [tex](70\%)\cdot (1000 - x) = 0.70\cdot (1000 - x) = 700 - 0.70\, x[/tex] students.
With a similar logic, the number of music students in the merged east campus will be [tex]30\% \times 1000 = 300[/tex].
The question implies that the sum of students in the two campuses should be equal to the number of music students in the east campus. That is:
[tex]0.20\, x+ (700 - 0.70\, x) = 300[/tex].
Solve for [tex]x[/tex]:
[tex]x = 800[/tex].
In other words, there are [tex]800[/tex] students in the north campus and [tex](1000 - 800) = 200[/tex] students in the south campus before the merger.

Answer:
(0, - 23 )
Step-by-step explanation:
Find the equation of the line in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 72, 25) and (x₂, y₂ ) = (- 36, 1) ← 2 ordered pairs from the table
m = [tex]\frac{1-25}{-36+72}[/tex] = [tex]\frac{-24}{36}[/tex] = - [tex]\frac{2}{3}[/tex] , thus
y = - [tex]\frac{2}{3}[/tex] + c
To find c substitute any ordered pair into the equation
Using (- 54, 13 ) , then
13 = 36 + c ⇒ c = 13 - 36 = - 23 ← y- intercept
Thus coordinates of y- intercept = (0, - 23 )

I have one half of a circle and I want to divide it by 1/6 how many pieces would I have
Different Question. Please explain your answer
Answer:
(x-6)^2 + (y+8)^2 = 25
Step-by-step explanation:
The equation for a circle can be written as
(x-h)^2 + (y- k)^2 = r^2
where (h,k) is the center and r is the radius
The diameter is 10 so the radius is 10/2 =5
the center is 6,-8
(x-6)^2 + (y- -8)^2 = 5^2
(x-6)^2 + (y+8)^2 = 5^2
(x-6)^2 + (y+8)^2 = 25

The length of a rectangle is 10m greater than the width. The area is 24m^2
Answer:
length: 12m
width: 2m
Step-by-step explanation:
24 = a*w
a = w+10
then:
24 = (w+10)w
24 = w*w + 10*w
24 = w² + 10w
0 = w² + 10 - 24
w = {-10±√((10²)-(4*1*-24))} / (2*1)
w = {-10±√(100+96)} / 2
w = {-10±√196} / 2
w = {-10±14} / 2
only positive numbers:
w = {-10+14}/2
w = 4/2
w = 2m
a = w+10
a = 2 + 10
a = 12m
Check:
24 = 12*2

Answer:
x = 151
Step-by-step explanation:
In the figure given, x is an exterior angle of the ∆.
According to the exterior angle theorem, x = the sum of the two opposite interior angles of the ∆.
One of the opposite angles measures 101°, while the second opposite angle equal 50°, since line l is parallel to m, alternate interior angles are equal.
Therefore, x = 101 + 50 = 151°

Graph the line whose x-intercept is 5 and whose y-intercept is -6.
Answer:
See attached image
Step-by-step explanation:
We can easily graph the equation if we know it’s y and x intercepts. We can plot these points on a coordinate plane then connect them using a ruler, then extend these further.
Mathematically, we can find the slope which is rise over run. Every time x increases by 5, y increases by 6. This means the slope is [tex]\frac{6}{5}[/tex]. We also know the y-intercept is -6, so the equation is [tex]y=\frac{6}{5}x - 6[/tex].

17. The owner of an organic fruit stand also sells nuts. She wants to mix cashews worth $5.50 per pound with peanuts worth
$2.30 per pound to get a 1/2 pound mixture that is worth $2.80 per pound. How much of each kind of nut should she include
in the mixed bag?
A. Cashews: 0.10 lb.; peanuts: 0.40 1b.
B. Cashews: 0.42 lb.; peanuts: 0.08 1b.
C. Cashews: 0.40 lb.; peanuts: 0.10 1b
D. Cashews: 0.27 lb.; peanuts: 0.23 1b.
E. Cashews: 0.23 lb.; peanuts: 0.27 1b.
F. Cashews: 0.08 lb.; peanuts: 0.42 1b
Answer:
E
Step-by-step explanation:
Let's let c denote the amount of cashews and let's let p denote the amount of peanuts.
So, the owner wants to mix cashews worth $5.50 per pound with peanuts worth $2.30 per pound to get a 1/2 pound mixture that is worth $2.80 per pound.
In other words, the total pounds as an equation is:
[tex]c+p=0.5[/tex]
Also, the price would be:
[tex]5.5c+2.3p=(p+c)2.8[/tex]
Since we mixed the peanuts and cashews, our sum would be 2.8(p+c).
And we already determined that p+c is 0.5. Thus, substitute:
[tex]5.5c+2.3p=(0.5)(2.8)[/tex]
Simplify:
[tex]5.5c+2.3p=1.4[/tex]
Now, we can solve the system of equations. Isolate a variable from the very first equation:
[tex]c+p=0.5[/tex]
Subtract p from both sides:
[tex]c=0.5-p[/tex]
Now, substitute this into the equation earlier:
[tex]5.5c+2.3p=1.4\\5.5(0.5-p)+2.3p=1.4[/tex]
Distribute:
[tex]2.75-5.5p+2.3p=1.4[/tex]
Combine like terms:
[tex]2.75-3.2p=1.4[/tex]
Subtract both sides by 2.75:
[tex]-3.2p=-1.35[/tex]
Divide everything by -3.2:
[tex]p=0.412875[/tex]
Now, find c:
[tex]p+c=.5[/tex]
Substitute:
[tex]c+0.421875=.5[/tex]
Subtract:
[tex]c=0.078125[/tex]
Thus, the owner would need 0.08 pounds of cashews and 0.42 pounds of peanuts.
Our answer is E.
