Answer:

Ed can arrange the 13 songs in 6,227,020,800 ways.

Step-by-step explanation:

ed is going to burn a cd which has 13 songs.

In general, the arrangement is nothing but "n" distinct objects can be arranged in n! ways.

There are 13 palaces.

The first place filled in 13 ways

The second place filled in 12 ways.

The third place filled in 11 ways.

.....

The thirteenth filled in 1 ways

= 13.12.11. 10.9.8.7.6.5.4.3.2.1

13! =  6,227,020,800

Ed can arrange the 13 songs in 6,227,020,800 ways.

Hope this will helpful.

Thank you.

Write an equation in slope-intercept form of a line that passes through the point (8,-0) and is perpendicular to the line x - 3y
IceJOKER [234]

Step-by-step explanation:

let eqn be y = mx + b.

3y = x - 15

y = 1/3x - 5

perpendicular means product of grad = -1

hence m = -3.

sun (8, 0):

8 = -3(0) + b

b = 8

therefore, equation if the line is y = -3x + 8

Mailyn loves cookies. She can eat 32 in an hour. Her brother Juan, however, needs 3 hours to eat the same amount of cookies. How
bezimeni [28]

we know that

1) Mailyn can eat 32 cookies in an hour

1 hour  is equal to 60 minutes

<u>Find how cookies eats Mailyn in one minute</u>

by proportion

\frac{32}{60} \frac{cookies}{minutes}= \frac{x}{1} \frac{cookie}{minutes} \\\\ x=32/60\\x=0.53 \ cookies

2) Juan needs 3 hours to eat 32 cookies

<u>Find how cookies eats Juan in one minute</u>

by proportion

\frac{32}{180} \frac{cookies}{minutes}= \frac{x}{1} \frac{cookie}{minutes} \\\\x=32/180 \\x=0.18\ cookies

<u>3) Find how long will it take them to eat 40 cookies together</u>

we know that

Maylin and Juan eats in one minute together ---------> (0.53+0.18)=0.71 cookies

so

by proportion

\frac{0.71}{1} \frac{cookies}{minutes}= \frac{40}{x} \frac{cookie}{minutes} \\\\0.71*x=40\\x=56.34 \ minutes

therefore

<u>the answer is</u>

56.34\ minutes

100 POINTS QUESTIONS IN PICTURES

First picture
ABC is a triangle so
m<A +m<B+m<C = 180
6x - 1 + 20 + x + 14 = 180
7x + 33 = 180
7x = 180 - 33
7x = 147
x = 147/7
x = 21
m<A = 6x - 1 = 6(21) - 1 = 125
m<C = x + 14 = 21 + 14 = 35
answer:
m<A = 125
m<C = 35
-----------------------------------------
second picture

ABC is a triangle so
m<A +m<B+m<C = 180
48 + 6x - 28 + 2x = 180
8x + 20 = 180
8x = 180 -20
8x = 160
x = 160/8
x = 20

m<B = 6x - 28 = 6(20) - 28 = 120 - 28 = 92
m<C = 2x = 2(20) = 40

answer:
x = 20
m<B = 92
m<C = 40
