mrs.smith owned one square mile of land. when she moved she gave an equal part of the land to her 3 children,amy,brianna ,and ch

Black_prince [1.1K]

Mrs.smith divided one square mile of land to her 3 children,amy,brianna ,and chad.

1 mile is divided among each children . so the fraction of land each one get is $\frac{1}{3}$

Amy's land = $\frac{1}{3}$

Brianna's land = $\frac{1}{3}$

Chad's land = $\frac{1}{3}$

Amy decided to divide her portion of the land equally between her 2 children.

We know Amys land = 1/3

1/3 is divided among two children so we divide the fraction by 2

$\frac{\frac{1}{3}}{2}$ = $\frac{1}{3} * \frac{1}{2}$

= $\frac{1}{6}$

$\frac{1}{6}$ fraction of mrs. smith's land one of amy's children own.

Chad divided his land equally among his 6 children

We know Amys land = 1/3

1/3 is divided among 6 children so we divide the fraction by 6

$\frac{\frac{1}{3}}{6}$ = $\frac{1}{3} * \frac{1}{6}$

= $\frac{1}{18}$

$\frac{1}{18}$ fraction of mrs. smith's land one of Chad's children own.

If "x" is equal to 6, what is the value of the following expression? y = 2x + 9x + 3

ser-zykov [4K]

Answer:

$y = 69$

Step-by-step explanation:

Given the following question:

$y=2x+9x+3$
$x=6$

Substitute and solve using PEMDAS:

$y=2x+9x+3$
$y=2(6)+9(6)+3$
$2\times6=12$
$y=12+9(6)+3$
$9\times6=54$
$y=12+54+3$
$12+54=66$
$66+3=69$
$y=69$

Your answer is "y = 69."

Hope this

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

In this problem:

The options are:

10 light appetizers

12 salads

5 small entrees

7 dishes

5 desserts

He throws away

3 salads

2 kinds of dishes

So he will choose

One light appetizer, from a set of 10

One salad, from a set of 9

One entree, from a set of 5

One dish, from a set of 5

One dessret, from a set of 5.

$T = P_{(10,1)} \times P_{(9,1)} \times P_{(5,1)} \times P_{(5,1)} \times P_{(5,1)} = \frac{10!}{(10-1)!} \times \frac{9!}{(9-1)!} \times \frac{5!}{(5-1)!} \times \frac{5!}{(5-1)!} \times \frac{5!}{(5-1)!} = 11250$
