Find the number of ways to purchase 5 different kinds of juices from a selection of 10 juices

1 answer:

8 0

Formula for combinations:
(n!)/(r!(n-r)!)

For you, this is:
10!/(5!(10-5)!) = 10!/5!5! = (10•9•8•7•6•5•4•3•2)/(5•4•3•2)(5•4•3•2) = (10•9•8•7•6)/(5•4•3•2) = 30240/120=252 different ways.

Answer:

208 feet

Step-by-step explanation:

We have to multiply 4x4 to get 16, and since there looks like there are 5 small squares we multiply 5x16 to get 80. And then there are 2 bigger squares that are 8x8 to get 64, then we multiply by 2 to get 128, then we add 80 (the sum of the 5 smaller squares) to get to a total of 208.

An expression is shown 30×8×103 P.s the three is in top of the 10 What is the value of the expression

lesya692 [45]

Answer: 2.4×10^5

Step-by-step explanation:

30×8×10^3

First multiply and forget about ×10^3 for now:

30×8 = 240

Then add back the ×10^3:

240×10^3

Then simplify:

2.4×10^5

To check the answer:

30×8×10³=

30×8000= 240000

Then simplify:

240000 = 2.4 ×10⁵

you invest $1000 in an account at 2.5% per year simple interest. How much will you have in the account at the beginning of the 4

AlladinOne [14]

Answer:

Step-by-step explanation:

I = PRT

P = 1000

R = 2.5% or 0.025

T = 4

I = (1000)(.025)(4)

I=100

1000+100=1100

but the answer choices???

If two points known on the line AB in the coordinate plane is (7,15) and (18,42), calculate the following..

Ksju [112]

Answer:

Slope = 27/11
AB = 29.15 u

Step-by-step explanation:

Given :-

Two points are given to us .
The points are A(7,15) and B(18,42)

To Find :-

The slope of the line .
The length of line AB .

We can find the slope of the line passing through the points $( x_1,y_1)$ and $( x_2,y_2)$ as ,

$\implies m = \dfrac{ y_2-y_1}{x_2-x_{1}}$

Plug in the respective values ,

$\implies m = \dfrac{ 42-15}{18-7} \\\\\implies \boxed{ m = \dfrac{ 27}{11 }}$

Hence the slope of the line is 27/11 .

$\rule{200}2$

Finding the length of AB :-

We can find the distance between them by using the Distance Formula .

$\implies Distance =\sqrt{ (x_2-x_1)^2+(y_2-y_1)^2} \\\\\implies Distance =\sqrt{ (18-7)^2+(42-15)^2 } \\\\\implies Distance =\sqrt{ 11^2 + 27^2 } \\\\\implies Distance =\sqrt{ 121 + 729 } \\\\\implies Distance = \sqrt{ 850} \\\\\implies \boxed{ Distance = 29.15 \ units }$

Hence the length of AB is 29.15 units .
