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.

Find the scale factor
Answer:
the scale factor is penguin
jkjk the scale factor is 1/2
Step-by-step explanation:
to find the scale factor you take the coordinates of the image and divide it by the coordinates of the preimage
ex. A' coordinates are (3,1)
A coordinates are (6,2)
3/6=1/2
1/2=1/2
therefore the scale factor is 1/2

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.

What fraction of the floats were not from a sports team? Write in simplest form.
Answer:
[tex]\frac{2}{3}[/tex]
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
= 1 - [tex]\frac{1}{3}[/tex]
= [tex]\frac{2}{3}[/tex]
[tex]\frac{2}{3}[/tex]rd fraction of Parade Float were not from a sports team.
A flower bed is in the shape of a triangle with one side twice the length of the shortest side and the third side is 25 feet more than the length of the shortest side. Find the dimensions if the perimeter is 157 feet
What is the length of the shortest side?
What is the length of the second side?
What is the length of the third side?
Answer:
shortest: 33 feet
second: 66 feet
third: 58 feet
Step-by-step explanation:
s = shortest side (33)
2s = second side (66)
25 + s = third side (58)
157 = s + 2s + 25 + s
157 = 4s + 25
4s = 132
s = 33

a girl is three years older than his brother. the product of their ages is 54, find their ages
Answer:
The sister is 25.5. The brother is 28.5.
Step-by-step explanation:
25.5 + 28.5 = 54.
The boy's age is 9.
The girl's age is 12.
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.

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.
