We have to find the area of the floor in order to know how many square meters of flooring they need.

The area of the floor is:
42 m* (39 m)= 1,638 m^(2)

They need 1,638 m^(2) of flooring.

Hope this helps~

You buy a car for 20,000 dollars and pay 5% in tax. How much is the tax?
lora16 [44]

Answer: $1,000

Step-by-step explanation:

We are trying to find 5% of 20,000. Always remember that the "of" can be changed to a multiplication, and that "percent" means per hundred.  So you will write (5/100) x 20,000 = 0.05 x 20,000 = $1,000.00

skad [1K]
Total number of parts:
2+3=5.

Each part is:
20 cookies/ 5 parts= 4 cookies/part.

Number of chocolate cookies is:
4 cookies/part* 2 parts= 8 cookies.

Number of sugar cookies is:
4 cookies/part* 3 parts= 12 cookies.

There are 8 chocolate cookies and 12 sugar cookies~

Suppose your salary in 2012 is $65,000 if the annual inflation rate is 4%, what salary do you need to make in 2021 in order for
vekshin1

The salary in 2012 was $65,000.

If the inflation rate is 4%, the salary should increase at least 4% per year to keep up with inflation.

Then, we can calculate the salary adjusted by inflation in 2021 as:

S_{2021}=S_{2012}\cdot(1+i)^{2021-2012}=S_{2012}\cdot(1+i)^9

Replacing with the data, we get:

\begin{gathered} S_{2021}=S_{2012}\cdot(1+i)^9 \\ S_{2021}=65000\cdot(1+0.04)^9 \\ S_{2021}=65000\cdot1.04^9 \\ S_{2021}\approx65000\cdot1.4233118 \\ S_{2021}\approx92515.27 \end{gathered}

Answer: the adjusted salary to keep up with inflation should be $92,515.27 in 2021.

PLEASE HELP ME ASAP!!!!!!!!!!!!!!!!!!!!!!!!! 3) This problem is called the Collatz Conjecture and is an unproven statement in ma
Aneli [31]

The set of numbers in the Collatz Conjecture are 1, 4, 2, 1, 4, 2, 1, 4, 2....

<h3>How to generate the numbers in the Collatz Conjecture</h3>

To start with, we make use of the following starting point:

Starting point = 1

The rule is given as:

  • If the last number is odd, multiply it by 3 and add 1.
  • If the last number is even, divide the number by 2.

1 is an odd number.

So, we use the first rule

So, we have:

1 * 3 + 1 = 4

4 is an even number.

So, we use the second rule

So, we have:

4/2 = 2

So, the first three numbers in the Collatz Conjecture are:

1, 4, 2

Using the given rules, we have:

1, 4, 2, 1, 4, 2, 1, 4, 2....

The above means that there is only one set of repeating numbers in the Collatz Conjecture.

Hence, the set of numbers in the Collatz Conjecture are 1, 4, 2, 1, 4, 2, 1, 4, 2....

<h3>Fibonacci sequence</h3>

The first and the second numbers are given as:

First = 2

Second = 5

The current term of a Fibonacci sequence is the sum of the previous two terms.

Using the above rule, the first 10 terms are:

2, 5, 7, 12, 19, 31, 50, 81, 131, 212

<h3>The sum of the first 10 terms of the new sequence</h3>

We have:

2, 5, 7, 12, 19, 31, 50, 81, 131, 212

Add the terms

Sum = 2+ 5+ 7+ 12+ 19+31+50+81+131+212

Evaluate

Sum = 550

Hence, the sum of the first 10 terms of the new sequence is 550
