6 minutes...

50°

Step-by-step explanation:

40° + 90° + ? = 180°

130° + ? = 180°

? = 180° - 130°

? = 50°

Answer: 50 degrees

Step-by-step explanation: The interior angles add up to 180.

1. 40 + 90 + ? = 180

     130 + ? = 180

   -130         - 130

            ? = 50

Answer:

The slope is 5/3

Step-by-step explanation:

Hello NiX010101!

[tex] \huge \boxed{\mathfrak{Question} \downarrow}[/tex]

Solve : [tex]\frac{ 3x-2 }{ 4 } - \frac{ 2x+3 }{ 3 } = \frac{ 2 }{ 3 } -x\\[/tex]

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

[tex]\frac{ 3x-2 }{ 4 } - \frac{ 2x+3 }{ 3 } = \frac{ 2 }{ 3 } -x \\ [/tex]

Multiply both the sides by the LCM of 4, 3 which is 12. After some simplification you'll get it as ..

[tex]3\left(3x-2\right)-4\left(2x+3\right)=8-12x [/tex]

Now, use the distributive property to open the brackets.

[tex]3\left(3x-2\right)-4\left(2x+3\right)=8-12x \\ 9x - 6 - 8x - 12 = 8 - 12x[/tex]

Now, bring the like terms together & simplify it.

[tex]9x - 6 - 8x - 12 = 8 - 12x \\ 9x - 8x - 6 - 12 = 8 - 12x \\ x - 18 = 8 - 12x \\ x + 12x = 8 + 18 \\ 13x = 26 \\ x = \frac{26}{13} \\ \large \boxed{\boxed{ \bf x = 2}}[/tex]

We got the value of x as 2.

The images of the scatter plots

Describing the scatterplot a

On the scatter plot, we can see that

The points appear to be on a straight line

Also, we can see that

As the x values increases the y values decreases

This represents a negative association.

Hence, the correlation is negative

Step-by-step explanation:

To factor this equation we want to find two numbers that multiply to -90 but also add/subtract to 1.

Those two numbers are 10 and -9 (10×-9=-90, 10-9=1)

Answer:

[tex](m-9)(m+10)[/tex]

Step-by-step explanation:

When you are given an expression in this format

[tex]ax^2+bx+c[/tex]

You must find two numbers that add up to b while the product is c.

You do trial and error to figure it out for your equation.

[tex]m^2+m-90[/tex]

Hmm... what two numbers add up to 1 and multiplied together equal -90.

Start off with pairs that can equal 90.

45 2

18 5

9 10

Ok, well 45 * 2 does equal 90 but 45 + 2 = 47and 45 + -2 = 43 but there's no way I can make it equal to 1. Next!

18 * 5 equals 90 but 18 + -5 = 13 and 18 + 5 = 23, I can just tell that there's no way I can make this equal to 1.

9 * 10 equals 90, 9 + 10 = 19 but 9 + -10 = -1. Now, that's interesting, We have -1 but we need 1. All we have to do is flip the order. 10 + -9 = 1. And -9 * 10 = -90, PERFECT!

Now use the two numbers and put it in factored form.

[tex](m-9)(m+10)[/tex]

Answer: 3

Step-by-step explanation:

The slope is given by the coefficient of x, in an equation of the form y=mx+c.

We want to find a proportional relationship between the number of pilots and aircraft, and use that to find the number of aircrafts for a given number of pilots.

We can expect to have 94 aircrafts if there are 250 pilots.

Let's see how to get that.

We start by defining what a proportional relationship is.

A proportional relationship between two variables x and y can be written as:

y = k*x

Where k is the constant of proportionality.

Here we do know that there are 40 pilots for every 15 aircrafts, then we can replace these values in the general proportional equation, where x will be the number of aircrafts and y the number of pilots.

40 = k*15

40/15 = k

Now we know the proportional relationship:

y = (40/15)*x

Now to find the number of aircrafts given that we have 250 pilots, we just need to replace the number of pilots by 250 and solve for x:

250 = (40/15)*x

250*(15/40) = x = 93.75

We can round this to the next whole number, 94.

So we can expect to have 94 aircrafts if there are 250 pilots.
