Solve the proportion.
20/13 = 60/d
d=
Answer:
[tex]d = 39[/tex]
Step-by-step explanation:
1) Multiply both sides by d.
[tex] \frac{20}{13} d = 60[/tex]
2) Simplify 20/13d to 20d/13.
[tex] \frac{20d}{13} = 60[/tex]
3) Multiply both sides by 13.
[tex]20d = 60 \times 13[/tex]
4) Simplify 60 × 13 to 780.
[tex]20d = 780[/tex]
5) Divide both sides by 20.
[tex]d = \frac{780}{20} [/tex]
6) Simplify 780/20 to 39.
[tex]d = 39[/tex]
Therefor, the answer is d = 39.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Boy's age = x
Girl's age:
y = x + 3
Now,
x (x + 3) = 54
x² + 3x - 54 = 0
x² + (9 - 6) - 54 = 0
x² + 9x - 6x - 54 = 0
x(x + 9) - 6(x + 9) = 0
x - 6 = 0
x = 6
x + 9 = 0
x = -9 ( cannot be negative)
Now,
x = 9
Boy's age = 9
Girl's age = 9 + 3 = 12
Thus,
The boy's age and the girl's ages are 9 and 12.

A movie theatre charges adults $10 to see a movie and charges children $6. If there wereq 120 people who saw a movue and the theatre collected $928, home many attendees were adults
Answer:
The number of adults tickets sold equals 52.
Step-by-step explanation:
First, we need to establish the system of equations:
x= number of adults tickets sold
y= number of kids tickets sold
10x + 6y= 928
x + y=120
Now, we isolate x in one equation and change it in the other to obtain its value:
x= 120 - y
10(120 - y) + 6y = 928
1,200 - 10y + 6y = 928
272 = 4y
68 = y
x= 120 - 68= 52

A coordinates are (6,2)
3/6=1/2
1/2=1/2
therefore the scale factor is 1/2

find the rule ans the graph of the function whose graph can be obtained by performing the translation 4 units peft and 5 units down on the parent function f(x)=ln(x)
a. f(x)=ln(x+4)-5
b. f(x)=(x-5)-4
c. f(x)=ln(x-4)-5
d. f(x)=ln(x+5)-4
The answer choices are 10, 15, 30, 35.
Lets us start with finding the inner angles of the triangle. The bottom right angle shall be 70 degrees as it is opposite. The 100 degrees shall add together to make 200. 360-200 = 160. 160 / 2 = 80. So, Now we know bottom left angle (80) and bottom right (70). 80 + 70 = 150. In a triangle, angles add to 180 so 180 - 150 = 30. 30 = 2x which means that x = 15

The graph of f(x) = x2 was transformed to create a graph g(x) =f(x)+2.
Which statement about the graphs is true?
The vertex of the graph of g is 2 units above the vertex of the graph of f.
The vertex of the graph of g is 3 units to the right of the vertex of the graph of f.
The vertex of the graph of g is 2 units below the vertex of the graph of f.
The vertex of the graph of g is 2 units to the left of the vertex of the graph of f.
Answer:
The vertex of the graph of g is 2 units above the vertex of the graph of f.
Step-by-step explanation:
The vertex of the graph of g(x) is 2 units above the vertex of the graph of f(x). Then the correct option is A.
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
The graph of f(x) = x² was transformed to create a graph g(x) =f(x)+2.
Then the g(x) will be
g(x) = x² + 2
We know that the graph of the g(x) shifted to 2 units upward because we added 2 in the function.
The graph is shown.
The vertex of the graph of g(x) is 2 units above the vertex of the graph of f(x).
Thus, the correct option is A.

Based on the cards shown, what is P(pink or even)?
1/5
7/10
9/10
Answer:
7/10
Step-by-step explanation:
To solve this, first find how many of the cards or even. There are 5 even cards out of these 10 cards, so we have the fraction 5/10. Next, we can see that there are 4 pink cards. So, we also have the fraction of 4/10. Then, add these two fractions.
5/10 + 4/10 = 9/10.
But, since the pink 8 card and the pink 10 card are both pink and even, they were counted twice. So, we need to subtract 2/10 from 9/10. This is 7/10.

Step-by-step explanation:
Fraction of the floats that belongs to sports team = [tex]\frac{6}{18}[/tex]
= [tex]\frac{1}{3}[/tex]
Therefore, fraction of floats that were not from a sports team = 1 - fraction of floats that belongs to sports team
