How many different 11-letter arrangements can be made using the letters in the word Firecracker?

zhenek [66]

Answer:

Total number of arrangements = 1,663,200

Step-by-step explanation:

Given:

11 - letter

FIRECRACKER

F = 1

I = 1

R = 3

E = 2

C = 2

A =1

K = 1

Find:

Total number of arrangements = ?

Computation:

Note: Repeated letter will be avoid.

$Number\ of\ arrangements = \frac{!11}{!3 \times !2 \times !2}\\\\Number\ of\ arrangements = \frac{!11}{!3 \times !2 \times !2} \\\\Number\ of\ arrangements = \frac{11 \times 10 \times 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3}{3 \times 2 \times 2 } \\\\Number\ of\ arrangements = 1,663,200$

Total number of arrangements = 1,663,200

Yesterday Clara reached 4 people in 10 phone calls while Toby reach three people in 8 phone calls if they continue at this rate

SashulF [63]

Answer:

Clara will reach more people in 40 phone calls.

Step-by-step explanation:

If Both of them had 40 phone calls you would divide 40 phone calls to how much they actually had. In this case for Clara it's 40 divided by 10 which is 4, And then you have to multiply 4x4 which is 16. For Toby He had to divide 40 by 8 which is 5, and then multiply 3x5 which is 15. Therefore Clara had reached more phone calls then Toby.

22x+70=17x-95 show step by step please

GalinKa [24]

$22x + 70 = 17x - 95$
Move variables to the left by adding their opposites to both sides. Eliminate the opposites.

$22x - 17x + 70 = - 95$
Move constants to the right by adding their opposites to both sides. Eliminate the opposites.

$22x - 17x = - 95 - 70$
Collect the like terms by subtracting their coefficients and numbers.

$5x = - 95 - 70$
Calculate the sum or difference. Extract the negative sign from the expression. Add the numbers.

$5x = - 165$
Divide both sides of the equation by 5 and calculate the quotient.

$x = - 33$
