Step-by-step explanation:
The ratio x:y is 1:3
Which of the following statements are correct?
A. x is 1/3 of y
B. y is 2 of (x + y)
C x is 1/4 of y
D. y is 3/4 of x
Answer:
A. & B. are the corect answers
Step-by-step explanation:
Answer:
A and B
x is [tex]\frac{1}{3}[/tex] of y
AND
y is [tex]\frac{3}{4}[/tex] of (x+y)
Step-by-step explanation:
x:y is 1:3
=> y is bigger than x
=> y is 3x bigger than x
=> y = 3 lots of x
=> [tex]y =[/tex] [tex]3x[/tex]
=> [tex]\frac{y}{3}[/tex] [tex]= x[/tex]
=> [tex]\frac{1}{3} y[/tex] [tex]= x[/tex]
So x is [tex]\frac{1}{3}[/tex] of y
y is [tex]\frac{3}{4}[/tex] of (x+y)
If x = 1 and y = 3 (substitute in values)
=> 3 is [tex]\frac{3}{4}[/tex] of (4)
=> 3 is [tex]\frac{3}{4}[/tex](4)
=> 3 is ([tex]\frac{3}{4}[/tex]x4)
=> 3 = 3
Therefore, y is [tex]\frac{3}{4}[/tex] of (x+y) is true
So the answers are:
x is [tex]\frac{1}{3}[/tex] of y
AND
y is [tex]\frac{3}{4}[/tex] of (x+y)
A jar contains 6 red marbles, 3 green marbles, 5 white marbles, and 7 yellow marbles. Find the probability of drawing a green marble. All answers should be given as a fraction in simplest form!
Any help is appreciated! Thanks!
Answer:
simple - 1/21 chance
Step-by-step explanation:
since its asking for the probability of "a" marble, and not all the green marbles, you add everything up and slap what outcome (1 in this case) on top of the 21
here is cat
Answer:
3 is for green marbles
21 is the total of all marbles
Step-by-step explanation:
you only have 1 event so I think we don't need some formula or something
the formula is this if the event A and B has no intersection P( A U B)= P(A)+P(B)
and if it has intersection, the formula is like this P( A ∩ B)=P(A)+P(B)-P( A ∩ B)

solve the equation for x
2/3x-1/9x+5=20
Answer:
x=27
Step-by-step explanation:
You want to isolate the variables so you subtract 5 from both sides. Therefore the equation will be 2/3x-1/9x=15. You want to take away the fraction because no one likes fractions. You have to multiply everything by 9. Therefore, the equation will be 6x-x=135. 5x=135. You want to isolate x so you have to divide each side by 5. x=135/5. Simplify to get x=27.

A lampshade has a height of 12cm and upper and lower diameters of 10cm and 20cm A)what area of material is required to cover that curved surface of the frustum B)what is the volume of the frustum (Give both answers in terms of pie)
Answer:
[tex](a)\ Area = 195\pi[/tex]
[tex](b)\ Volume = 700\pi[/tex]
Step-by-step explanation:
Given
[tex]h = 12[/tex]
[tex]d_1 = 10[/tex] --- lower diameter
[tex]d_2 = 20[/tex] --- upper diameter
Solving (a): The curved surface area
This is calculated as:
[tex]Area = \pi l(r_1 + r_2)[/tex]
Where
[tex]r_1 = 0.5 * d_1 = 0.5 * 10 = 5[/tex] --- lower radius
[tex]r_2 = 0.5 * d_2 = 0.5 * 20 = 10[/tex] --- upper radius
And
[tex]l = \sqrt{h^2 + (r_1 - r_2)^2[/tex] ---- l represents the slant height of the frustrum
[tex]l = \sqrt{12^2 + (5 - 10)^2[/tex]
[tex]l = \sqrt{12^2 + (-5)^2[/tex]
[tex]l = \sqrt{144 + 25[/tex]
[tex]l = \sqrt{169[/tex]
[tex]l = 13[/tex]
So, we have:
[tex]Area = \pi l(r_1 + r_2)[/tex]
[tex]Area = \pi * 13(5 + 10)[/tex]
[tex]Area = \pi * 13(15)[/tex]
[tex]Area = 195\pi[/tex]
Solving (b): The volume
This is calculated as:
[tex]Volume = \frac{1}{3}\pi * h * (r_1^2 + r_2^2 + (r_1 * r_2))[/tex]
This gives:
[tex]Volume = \frac{1}{3}\pi * 12 * (5^2 + 10^2 + (5 * 10))[/tex]
[tex]Volume = \frac{1}{3}\pi * 12 * (25 + 100 + (50))[/tex]
[tex]Volume = \frac{1}{3}\pi * 12 * (175)[/tex]
[tex]Volume = \pi *4 * 175[/tex]
[tex]Volume = 700\pi[/tex]
Without looking, Tammy takes a marble out of a bag that contains 10 red marbles, 15 green marbles, and 25 blue marbles. She records its color and returns the marble to the bag. If Tammy repeats this process 90 times, how many times can she expect to pull out a red marble?
Answer:
18 is the answer
Step-by-step explanation:
added all the marbles she took out to see the total she took out which was 50
if she did it 90 times I need to see how much time 50 she did it more and that was so 90 divided by 50 is 1.8 and that times 10
(times because we want to see how many times the red marble would come out) and that’s 18

35 pictures = ?
Solve for one picture:
Variable x = mb per 1 picture
264/528 = 1/x
Cross multiply:
264 × x = 528 × 1
264x = 528
x = 528 ÷ 264

Answer:
x = 1+sqrt(69)/8 about 2.0383
or
x = 1-sqrt(69)/8 about -0.0383
Step-by-step explanation:
Use the quadratic formula:
(Move 17 to the left side first though)
(-b±√(b²-4ac))/2a
(1±sqrt(1-4*1*-17))/2(4)
x = 1±sqrt(69)/8
The most efficient method is the quadratic equation because the equation is not easily factorable and a!=1.

Given circle Q a measure of SR = 120 degree and a radius of 9 feet, as shown below determine the arc length of SR use mathematics to explain how you determined your answer. 
Volume and circles
Help please ❤️
Answer:
Arc length SR = 18.85 ft
Step-by-step explanation:
To get the arc length, we use the formula below
theta/360 * 2 * pi * r
theta is the central angle subtended by the arc which is 120 degrees
r is the radius of the circle which is 9 ft
Substituting these values, we have
120/360 * 2 * 3.142 * 9
= 18.85 ft

Answer:
y = -2/3x + 4
y+1 = -4/6(x + 5)
Step-by-step explanation:
y = -2/3x + 4
y+1 = -4/6(x + 5) *-4/6 is equal to -2/3
perpendicular lines have slope that are opposite signs and reciprocals
the slope of the original line in this problem is 3/2 so any line with a slope of -2/3 is perpendicular to it
Answer:
it will be any equation with a slope that is the opposite reciprocal of 3/2 or it's equivalent. So in this case, -2/3. be sure to check the negative does and see if other slopes are the same as -2/3 but in a different form.

18
Answer:
B.) -9
Step-by-step explanation:
The value of b if 3/2 is the axis of symmetry for the graph of the function f(x)=3x2+bx+4 is -9
How to calculate the axis of symmetry of a function?The standard equation of a function in vertex form is given as:
f(x) = (a + x)^2 + h
Given the function f(x)=3x^2+bx+4 with an axis of symmetry of 3/2, the vertex is expressed as:
3/2= -b/2a
-b/2(3)=3/2
-b/6=3/2
Cross multiply
-2b = 18
-b=9

Two similar cylinders have radii of 15 inches and 6 inches. What is the ratio of the surface area of the small cylinder to the surface area of the large cylinder.
Answer:
4:25
Step-by-step explanation:
Given that,
r₁ = 15 inches, r₂ = 6 inches
The area of the cylinder is given by :
[tex]A=2\pi rh+2\pi r^2[/tex]
The ratio of surface areas of two cylinders,
[tex]\dfrac{S_2}{S_1}=\dfrac{2\pi r_2h_2+2\pi r_2^2}{2\pi r_1h_1+2\pi r_1^2}\\\\\dfrac{S_2}{S_1}=(\dfrac{r_2}{r_1})^2\\\\=\dfrac{6}{15}^2\\\\=\dfrac{4}{25}[/tex]

Step-by-step explanation:
in a school ,the number of boys who play cricket is 3 times as much as a number of boys who play tennis. if 12 boys, who play cricket, play tennis instead, the number of boys who play each of these sports would be the same. find the number of boys who play tennis
Answer:
The number of boys who play tennis is 36.
Step-by-step explanation:
Let the number of boys who play tennis is x.
number of boys who play cricket = y
x = 3 y..... (1)
12 boys plays both cricket and tennis.
According to the question,
x - 12 = y + 1 2
3 y - 12 = y + 12
2 y = 24
y = 12
So, the number of boys who plays tennis is x = 3 x 12 = 36.
Find the equation of a straight
line passing through the point of
intersection of the lines
y = 2x +3 and x +y = 3 and
parallel to the line y = -5x +7
Answer:
y = -5x + 3.
Step-by-step explanation:
We can find the point of intersection by solving the system:
y = 2x + 3 .... 1
x + y = 3 ...... 2 from this:
y = 3 - x ....... .3
Equating equations 1 and 3:
2x + 3 = 3 - x
3x = 0
x = 0 so y = 2(0) + 3 = 3.
So the point of intersection is (0, 3).
So the required equation has slope -5 and passes through (0, 3) and, using the point-slope form of a straight line, we have:
y - 3 = -5(x - 0)
y - 3 = -5x
y = -5x + 3.
