The number of possible different 12-letter arrangements of the letters in the word “TRIGONOMETRY” is represented by

Answers

We will use formula for Permutations with repetition:
P(n, m1,m2,m3) = n! / m1! · m2! · m3!
In the word TRIGONOMETRY we have repetitions of letters: T, R and O.
P= $(12!)/(2!*2!*2!)= (12*11*10*9*8*7*6*5*4*3*2*1)/(2*1*2*1*2*1) =$ = 59,875,200

Matt bought 7 shirts for a total of $38. Tee shirts cost $5 and long sleeve shirts cost $6. How many of each type of shirt did he buy? HELP PLZ 100 POINTS

Answers

Answer:

tee shirt:4

sleeve shirt:3

Step-by-step explanation:

we are given two conditions

Matt bought 7 shirts for a total of $38
Tee shirts cost 5 dollars and long sleeve shirts cost 6 dollars

we want to figure out how many each type of shirt he bought

let tee and sleeve shirts be t and s respectively

according to the first condition

$\displaystyle t + s = 7$

according to the second condition

$\displaystyle5t + 6s = 38$

therefore

our system of linear equation is

$\displaystyle\begin{cases}t + s = 7 \n 5t + 6s = 38 \end{cases}$

now we need our algebra skills to figure out t and s

to do so we can use substitution method

cancel s from both sides of the first equation:

$\displaystyle t = 7 - s \: \cdots \: i$

now substitute the value of i equation to the second equation:

$\displaystyle 5(7 - s) + 6s = 38$

distribute:

$\displaystyle 35 - 5s+ 6s = 38$

collect like terms:

$\displaystyle s + 35 = 38$

cancel 35 to both sides:

$\displaystyle \therefore s = 3$

now substitute the value of s to the i equation:

$\displaystyle t = 7 - 3 \n \therefore \: t = 4$

hence,

he bought tee shirt4 and sleeve shirt3

Each week Marissa withdraws the same amount from her bank account the equation A=1550-90w represent the relationship between the amount of money remaining in her account ,A,in dollars , and the number of weeks of withdraws ,W.

For how many weeks has Marissa made withdraws when the amount remaining in the
account is $110??

A)14
B)16
C)17
D)18

Answers

Fill in your remaining amount (110) in a because a is your remaining amount.

Solve for w(weeks):

110=1550-90w Subtract 1550 on both sides of the equal sign to get:

-1440=-90w Now do the inverse operation and divide -90 on both sides to get:

16= w

So the answer is 16 weeks
