Step-by-step explanation:
12 stars = 30 balloons
? = 120 balloons
Solve
120/30 x 12 = 48
Answer:
48 stars
Step-by-step explanation:
This is an equation where you have to find an equivalent fraction.
So, it is given to us that 12/30 = something (x) /120.
So, what happened to 30 to make it 120 in the respective denominators? It was multiplied by 4.
So, that’s what you do to the numerator, multiply it by 4.
So 12 x 4 = 48.
Now put it back as a fraction 12/30 = 48/120

9 = 4 + b
5 = b
y = 4/3x + 5
Which of the following compositions of transformations will always produce the same image, regardless of the order in which the transformations are performed?
Answer:
All compositions are affected by the order in which they are performed
Step-by-step explanation:
We have the following transformations:
-translation
-reflection
-rotation
Each of them are affected by the order in which they are performed, for example:
If we rotate we have:
(x, y) -> (y, -x).
After the reflection:
(y, -x) -> (-y, -x).
If we translated by <2, 5> and reflected through the y-axis:
After the translation, (x, y) -> (x + 2, y + 5)
In other words, all compositions are affected by the order in which they are performed

Answer: a) 110√2 meters
b) 2.42 hectares
Step-by-step explanation:
a) Since it is a square, the diagonal cuts the square into two 45-45-90 triangles where the diagonal is the hypotenuse. Therefore, the sides are length x and the diagonal is length x√2.
[tex]x\sqrt2=220\\\\\\x=\dfrac{220}{\sqrt2}\\\\\\x=\dfrac{220}{\sqrt2}\bigg(\dfrac{\sqrt2}{\sqrt2}\bigg)\\\\\\x=\large\boxed{110\sqrt2}[/tex]

Hey there! :)
Answer:
m∠y = 55°.
Step-by-step explanation:
Begin by solving for x since y and x are supplementary angles.
Recall that all of the angles in a triangle must sum up to 180°. Therefore:
180 - 30 - 25 = 125°.
x = 125°, therefore:
180 - 125 = 55°.
m∠y = 55°.
Answer:
55 Degrees

бу2 + 13y – 8 how to factorize this?
Answer:
We have 6y² + 13y - 8. We can rewrite this as 6x² + 16x - 3x - 8. Grouping terms we get 2x(3x + 8) - (3x + 8) and since both terms have the common factor of (3x + 8) the answer is (3x + 8)(2x - 1).
Examine the diagram, and answer the question. The points A(2,7) and B(−4,−3) are located in the coordinate plane as shown. Points A and B are shown in the coordinate plane at the locations indicated. What is the approximate distance between the two points?
Answer:
Option (2)
Step-by-step explanation:
Formula to get the distance between two points [tex](x_1, y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
The given points are A(2, 7) and B(-4, -3)
Distance between these points will be,
AB = [tex]\sqrt{(2+4)^2+(7+3)^2[/tex]
= [tex]\sqrt{6^2+10^2}[/tex]
= [tex]\sqrt{136}[/tex]
= 11.66
≈ 11.7 units
Therefore, distance between the points A and B is 11.7 units.
Option (2) will be the answer.

The radius of circle C is 6 units and the measure of central angle ACB is StartFraction pi Over 2 EndFraction radians. What is the approximate area of the entire circle? square units What is the approximate area of the entire sector created by central angle ACB? square units What is the approximate area of the shaded region only? square units
Answer:
Step-by-step explanation:
We khow that the radius of our circle is 6
Let A be the area of our cercle :
A= 6^2*Pi = 36 Pi = 113.09 sq.units
We khow that the mesure of our angle ABC is Pi over 2 wich is 90 degree
So this triangle ABC is a right one .
So I think that we must khow the area of this triangle to be able to khow the area of the sector .
We have a hint : ABC is 90 degree so it is the quarter of our cercle
We need to divide the area of the circle by 4

A salad bar offers vegetable platters in 4 sizes (small, medium, large, and super-sized) and 6 different vegetables to choose from. Different platters can be created by changing the size and/or the choice of vegetables. If Selena wants to order a platter with exactly 2 different vegetables, how many different platters could she create?
Answer:
The number of different platters Selena can create by selecting two different vegetables is 60 different platters
Step-by-step explanation:
The information given are;
The number of different sizes of salad available = 4
The number of different vegetable to choose from = 6
The number of vegetables Selena ordered = 2
The number of ways Selena can choose 2 vegetables out of 6 = ₆C₂ = 15 ways
The number of different platters (choice of vegetable and size of platter) Selena can create = The number of different sizes of salad available × The number of ways Selena can choose the vegetables
The number of different platters (choice of vegetable and size of platter) Selena can create = 4 × 15 = 60 different platters.

A certain university in the United States has a student enrollment of 19,100. Mr. Hill knows the percentage of students that are male and the percentage of students that are female. To conduct the simulation, Mr. Hill has placed one hundred colored chips in a bag, using the appropriate percentages of enrolled male and female university students. Red chips represent males, and yellow chips represent females.
Suppose a different student reaches in the bag, randomly selects their twenty chips, and estimates that 60% of the students are male. Based on this sample, what is a good estimate for the number of enrolled university students that are female?
Answer:
7640 Students are Girls
Step-by-step explanation:
10% of all students is 1,910
We know 60% is male so we do 1910 x 6 = 11460
Now we take the total - the amount of guys
19,100 - 11460 = 7640
40% is female = 7,640
Answer:
45%
40 yellow chips
Step-by-step explanation:
Total chips: 9 + 11 = 20
P(Male) = 9/20 × 100 = 45%
60% of 100
60/100 × 100
60 red
100 - 60 = 40 yellow chips

Y=x+3 y=2x+5 System of equations using Substitution
Answer: (-2,1)
Step-by-step explanation:
y=x+3
y=2x+5 substitute the y value in the first equation into the second equation
x+3 = 2x+5 now solve for x
-3 -3
x = 2x +2 subtract 2x from both sides
-2x -2x
-1x = 2 Divide both sides by -1
x= -2
The value of x is -2 to plot it into one of the equations to solve for y.
y= -2 + 3
y = 1
(-2,1)
Answer: x = − 2 and y = 1
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
/| y-x-3 = 0| y-(2*x)-5 = 0
We try to solve the equation: y-x-3 = 0
y-x-3 = 0 // + -x-3
y = -(-x-3)
y = x+3
We insert the solution into one of the initial equations of our system of equations
We get a system of equations:
/| x-(2*x)-5+3 = 0| y = x+3
-x-2 = 0 // + 2
-x = 2 // * -1
x = -2
We insert the solution into one of the initial equations of our system of equations
For y = x+3:
y = 3-2
y = 1
We get a system of equations:
/| y = 1| x = -2

a fruit drink is made by mixing 60ml of orange juice with 180ml of pineapple juice. what is the ratio of orange juice to pineapple juice in its simplest form?
Answer:
1:3
Step-by-step explanation:
both divide by 60 so do 60 divided by 60 which is one
then 180 divided by 60 which is three
this gives you the answer
Answer:
1:3
Step-by-step explanation:
a ratio is basically the same as a fraction just in a different form. so it would be 60/180 simplified. both 60 and 180 can be divided by 60. so you would divide both numbers by 60 to get 1/3. this cannot be simplified any further. then to put it as a ratio it would just be 1:3
A group of 20 people visited Anglesey for a weekend break.
• 10 of the group visited Beaumaris Castle.
• 13 of the group visited South Stack Lighthouse.
• 4 of the group did not visit either of these places.
Complete the Venn diagram below by stating the number of people in each region A,B,C and D to show this information.
The universal set, ε, contains all of the 20 people in the group.
Answer:
A = 4, B = 3, C = 7, D = 6
Step-by-step explanation:
A = 4 because A represents the number of people who didn't visit either place. This means that B + C + D = 20 - 4 = 16. To find C, which is the overlap we can do 10 + 13 - 16 = 7 so C = 7 which means B = 10 - 7 = 3 and D = 13 - 7 = 6.
Answer:
A = 4, B = 3, C = 7, D = 6
