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.

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.

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.

Answer:

35/26 = 1.346153846

Step-by-step explanation:

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

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

[tex]m=\frac{2}{5}[/tex]

Step-by-step explanation:

1. To find the slope we need to use the slope formula, [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

2. The points that were given were (0,0) and (5,2). Let's plug those into the formula.

[tex]\frac{2-0}{5-0}[/tex]

[tex]\frac{2}{5}[/tex]

So, your slope would be [tex]m=\frac{2}{5}[/tex]

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.
