In how many ways can four aces be drawn from a deck of cards? (Order is not important.)

natka813 [3]

Let's imagine that we have in the deck 52 cards. So what we need to do is to make a kind of "progression".So let me explain this by doing the procedure. we can use is like this:
4/52 * 3/51 * 2/50 * 1/49 =
24 / 6497400 = 
1 / 270725

I know that is my answer but how do I work it out on notebook paper

'karen is making 14 different kinds of greeting cards she is making 12 of each kind how many greeting cards does she making'

ok so that is multiplication

14 times 12 since it is 12 of each and 14 of them so
14 times 12=

do you guys still do multiplication by the tower meathod or such if so, here it is

14
12 x


so it is
if you had
 a b
 c d x
 (ad)(bd)
(bc)(ac) +
result

first you do
2 times 4 then place it below the 2

14
12 x
 8

then you do 2 times 1 then place it below

14
12 x
28

then you move on the the one

1 times 4

14
12 x
28
4

then 1 times 1

 14
 12 x
 28
14

then we add

14
 12 x
 28
14 +

answer is 168

The slope for is JK 1/3 , the slope of LK is -2 , the slope of ML is 2/5 , and the slope of MJ is 3/2 . Quadrilateral JKLM is not a parallelogram because neither pair of opposite sides is parallel

Further explanation:

Given vertices are:

J(−4, 1) , K(2, 3) , L(5, -3) , and M(0, −5) .

We have to find the slopes before concluding any result

The formula for slope is:

$m=\frac{y_2-y_1}{x_2-x_1}$

So:

Slope of JK:

$m_1=\frac{3-1}{2-(-4)}\\=\frac{2}{2+4}\\=\frac{2}{6}\\=\frac{1}{3}$

Slope of LK:

$m_2=\frac{-3-3}{5-2}\\=\frac{-6}{3}\\=-2$

Slope of ML:

$m_3=\frac{-3-(-5)}{5-0}\\=\frac{-3+5}{5}\\=\frac{2}{5}$

Slope of MJ:

$m_4=\frac{1-(-5)}{-4-0}\\=\frac{1+5}{-4}\\=\frac{6}{-4}\\=-\frac{3}{2}$

As the slopes of all sides are different, the given quadrilateral is not a parallelogram because in order for the quadrilateral to be a parallelogram the opposite sides have to be parallel i.e. have equal slopes and there are no sides with equal slopes.

Jose asks his friends to guess the higher of two grades he received on his math tests. He gives them two hints. The difference o

tatyana61 [14]

Answer : 96

x – y = 16 --------> equation 1

1/8 x + 1/2 y = 52

x is the higher grade and y is the lower grade

We solve the first equation for y

x - y = 16

-y = 16 -x ( divide each term by -1)

y = -16 + x

Now substitute y in second equation

1/8 x + 1/2 ( -16 + x ) = 52

1/8x - 8 + 1/2 x = 52

1/8x + 1/2x - 8 = 52

Take common denominator to combine fractions

1/8x + 4/8x -8 = 52

5/8x - 8 = 52

Add 8 on both sides

5/8x = 60

Multiply both sides by 8/5

x = 96

We know x is the higher grade

96 is the higher grade of Jose’s two tests.
