A 200-centimeter-long wire is cut into three peices. The second piece is three times as long as the first. The third piece is 2 times as long as the second. How long is each piece?

Answers

Answer 1
Answer: Assuming the value of the first piece is x, then the equation would be this:
x+3x+6x=200
Simplify, and you get:
10x=200
Solve for x:
x=20
So the first piece(x) was 20 cm long
The second piece(3x) was 60 cm long
The third piece(6x) was 120 cm long

Subtract (3 + 2i) from (–9 – 8i).a. –17 – 5i

b. –6 – 6i

c. –12 – 10i

d. 12 + 10i

Answers

The answer is -12-10i

Given two complex numbers

First complex number = 3+2i ....(1)

Second Complex number = -9-8i..... (2)

Subtracting  equation (1) from  equation (2)

As this is a subtraction between complex numbers hence the Real part gets subtracted from the  real part and the imaginary part gets subtracted from the imaginary part

( -9- 8i ) - ( 3 +2i )

= -9 -3 -8i - 2i

= -12 -10i

(-9-8i)-(3+2i)
= -9-8i-3-2i
Separate i and the numbers
= (-9-3)+(-8i-2i)
= -12-10i

Which expression is equivalent to 2(m − 5) + 6?2m − 1

2m + 22

2m − 4

2m + 16

Answers

The expression that is equivalent to 2(m - 5) + 6 is 2m - 4. Option C is correct.

The given algebraic equation consists of numbers, arithmetic operations, and variables. The first thing to do is to open the brackets. After that, we will sum up or subtract the like terms.

Given that:

  • = 2(m - 5) + 6
  • = 2m - 10 + 6
  • = 2m - 4

Therefore, we can conclude that the expression that is equivalent to 2(m - 5) + 6 is 2m - 4.

Write the number of permutations in factorial form. Then simplify, how many different ways can you and six of your friends sit in your assigned seats in math classA)6!; 120
B)6!;720
c)7!;2,520
D) 7!;5,040

Answers

Answer: D) 7!;5,040

Step-by-step explanation:

Given: The number of friends = 7

Permutations says that the number of different ways of arranging r objects out  of n objects is given by ;-

^nP_r=(n!)/((n-r)!)

By permutations the number of different ways they can sit is given by :-

^7P_7=(7!)/((7-7)!)=(7!)/(0!)\n\n=7*6*5*4times3*2*1\n\n=5,040

Therefore, the different ways can you and six of your friends sit in your assigned seats in math class = 5,040.

You and 6 of your friends. Total of 7 people.

The answer is D.) 7! ; 5,040
