The ratio of red cars to blue cars in a parking lot was 5:3 if there were 40 red cars how many blue cars would there be

Mathematics
1 answer:
AveGali [126]3 years ago
6 0

Answer:

24 blue cars

Step-by-step explanation:

Set up a proportion to solve this...

40/5 = x/3      (forty red cars is to five red cars as 'x' number of blue cars is to 3 blue cars)

Now solve by cross multiplying...

120 = 5x

    24 = x

WILL MARK BRAINLIEST!! PLZ HELP!!! 20 POINTS Create a graph of the polynomial function g(x) = (x + 2)(x − 1)(x − 2)
Gennadij [26K]

Answer:

We have: g(x)=(x+2)(x-1)(x-2)

multiply the 3 terms:

  • (x+2)(x-1)(x-2)
  • (x²-4)(x-1)
  • x^3 -x²-4x+4

This is a polynimial function with 2 vertices

The roots are approximatively:

0.8 and -1.5

their images are:

1.9 and 8.8

plot these two vertices and draw some other points

here is a drawing:

The button on Carey's jacket has a diameter of 8 millimeters. What is the button's circumference?
Ahat [919]

Answer:

25.12 millimeters is your answer.

Step-by-step explanation:

Circumference can be solved by using the equation:

c = 2πr or c = πd

Note that diameter (d) is equal to 8. Plug in 8 for d.

c = (8)(π)

Also note that π = 3.14. Multiply

c = (8)(3.14)

c = 25.12 millimeters.

25.12 millimeters is your answer.

Anyone! Please help me! I don't understand at all what to do! Help would be really appreciated :)
Rom4ik [11]

Answer: They are parallel

Step-by-step explanation:

If two lines are parallel , then they must have the same slope and if two lines are perpendicular , the product of their slope must be -1.

To check this , we must calculate the slope of the two lines given.

Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

from the first point

y_{1} = 2

y_{2} = 1

x_{1} = 5

x_{2} = -1

substituting the values

slope 1 = 1 - 2 / -3 - 5

slope1 = -1 / -8

slope 1 = 1/8

Using the same format to calculate the slope of the second line

y_{1} = -2

y_{2} = 0

x_{1} = -1

x_{2} = 15

slope 2 = 0 - (-2) / 15 - (-1)

slope 2 = 2/16

slope 2 = 1/8

Since slope 1 = slope 2 , this implies that the lines are parallel
