Answer: 84

Step-by-step explanation:

The formula to calculate the number of ways to select x things from n things is given by :-

^nC_x=\dfra{n!}{{!(n-x)!}

Now, if 3 bananas are to be selected from a group of 9, then the number of ways  will be  

^9C_3=\dfrac{9!}{3!(9-3)!}=\dfrac{9\times8\times7\times6!}{6\times6!}=84

Hence, the  number of ways to select 3 bananas from a group of 9 =84

The measures of the angles of a quadrilateral are in the
bearhunter [10]

Answer:

140

Step-by-step explanation:

Consider a square for just a second. It has 4 angles each of 90 degrees. The total number of degrees in a square is 4 * 90 = 360.

It should be at least an appeal to your intuition to say that a quadrilateral has a total of 360 degrees.

Therefore the ratio you have been given must have 4 angles that add to 360.

2x + 3x + 6x + 7x = 360

18x =360

x = 20

So the 4 angles are

2* 20 = 40

3*20 =  60

6*20 = 120

7*20 = 140

Total    360

The largest angle is 140

What is the slope of a line that is perpendicular to the line with equation 12x+3y=9?
Masteriza [31]

Answer:

perpendicular slope= 1/4

Step-by-step explanation:

you have to make the equation equal to y so that would be -4x+3=y

and then you just find the negative reciprocal of the slope -4 which would be 1/4
