The formula of combination is 

nCr= \frac{n!}{(n-r)!r!}

We have n=14 and r=10

14C10= \frac{14!}{(14-10)!10!} = 1001

Hence, there are 1001 ways of arranging 10 records from 14 records

Find the measure of each angle.
Galina-37 [17]

<u>Given</u>:

Given that the isosceles trapezoid JKLM.

The measure of ∠K is 118°

We need to determine the measure of each angle.

<u>Measure of ∠L:</u>

By the property of isosceles trapezoid, we have;

\angle K+\angle L=180^{\circ}

118^{\circ}+\angle L=180^{\circ}

           \angle L=62^{\circ}

Thus, the measure of ∠L is 62°

<u>Measure of ∠M:</u>

By the property of isosceles trapezoid, we have;

\angle L \cong \angle M

Substituting the value, we get;

62^{\circ}=\angle M

Thus, the measure of ∠M is 62°

<u>Measure of ∠J:</u>

By the property of isosceles trapezoid, we have;

\angle J \cong \angle K

Substituting the value, we get;

\angle J =118^{\circ}

Thus, the measure of ∠J is 118°

Hence, the measures of each angles of the isosceles trapezoid are ∠K = 118°, ∠L = 62°, ∠M = 62° and ∠J = 118°

I need help. I'm stuck on this one
inna [77]
Add 5/9 to both sides. common denominator would be 72 so you would multiply the top and bottom of 3/8 by 9 (bc 9x8 is 72) to get 27/72. you would multiply top and bottom of 5/9 by 8 to get 40/72 and you would add 40+27 which equals 67 so x=67/72 i believe

Please help me with this math question ​
Leona [35]

Answer:

X + Y - W - Z = 180

Step-by-step explanation:

In parallel lines If you use the rules of:

* Alternate angles are equal

* Linear Pair Angles supplement to 180

And use the picture below for calculating the result: finally we get

Z = Y - (180 - (X - W)) which becomes the answer above if you simplify the parentheses.

Find the zeros : x(x^2+13x+40)
Ksju [112]
The zeros are x= 0,-5,-8. the zeros are the x values where the graph intersects the x-axis. to find the zeros, you have to replace y with zero then solve for x.
