Find the value of the combination. 21 C 3 7,980 2,660 1,330

erik [133]

To evaluate the combination we proceed as follows:
21C3
Given nCk we shall have:
n!/[(n-k)!k!]
thus plugging the values in the expression we get:
21!/[(21-3)!3!]
=21!/(18!×3!)
=1330
Answer: 1330

Write as an ordered pair. 4x+2y=16 and -4y+x=4

Margaret [11]

Answer:

(4,0)

Step-by-step explanation:

4x+2y=16

-4y+x=4

Multiply the first equation by 2

2(4x+2y)=16*2

8x +4y = 32

Add the 2nd equation

8x +4y = 32

x -4y =4

--------------------

9x =36

Divide each side by 9

9x/9 = 36/9

x=4

Now solve for y

-4y +x =4

-4y +4 = 4

Subtract 4 from each side

-4y +4-4=4-4

-4y =0

Divide by -4

-4y/-4 =0/-4

y=0

A utility company measures gas consumption by the hundred cubic feet, CCF. The company has a three-step rate schedule for gas cu

sweet [91]

Answer:

$\$(4.65 + 0.55g)$

Step-by-step explanation:

Let the number of hundred CCF of gas consumed by the customer =g

$\text{When } 0 < g \leq 3\\ \text{Cost =} \$5\\\\\text{When } 3$

Therefore, when the hundred cubic feet, CCF of gas consumed is more than 9, the consumer pays for the first 9 and then pays for any subsequent CCF of gas at a rate of $0.55 per CCF

$\text{When g}>9 : \text{Cost =} 9.60+0.55(x-9)$

$=9.60+0.55g-4.95\\=\$(4.65 + 0.55g)$

PLEASE HELP ITS MATH THANK YOUUUU

NISA [10]

Answer: 10 meters

Explanation:

29 cm : blank meters

So how do we get from 348 cm to 29 cm?

To figure this out we divide.

348 divided by 28 = 12

we divided by 12 so we do the same with 120

120 divided by 12 = 10

So that’s the answer.

I hope this makes sense and helps you :)
