How to convert decimals to other decimals

Answers

Answer:

Step 1 − Divide the decimal number to be converted by the value of the new base.

Step 2 − Get the remainder from Step 1 as the rightmost digit (least significant digit) of new base number.

Step 3 − Divide the quotient of the previous divide by the new base.

Step 4 − Record the remainder from Step 3 as the next digit (to the left) of the new base number.

Step-by-step explanation:

Repeat Steps 3 and 4, getting remainders from right to left, until the quotient becomes zero in Step 3.

The last remainder thus obtained will be the Most Significant Digit (MSD) of the new base number.

The variable x is the variable, because you can choose any value for it. The variable, because it depends on variable y is called the x. Once you have chosen a value for x, the value of y is determined.​

bio = 258

sociology = 169

============================================================

Work Shown:

x = number of bio textbooks

y = number of sociology textbooks

x+y = 427 books sold total

y = x-89 since 89 less sociology textbooks were sold compared to bio

Apply substitution to get the following

x+y = 427

x+x-89 = 427 ... replace y with x-89

2x-89 = 427

2x = 427+89

2x = 516

x = 516/2

x = 258 bio textbooks were sold

y = x-89

y = 258-89

y = 169 sociology textbooks were sold

3*x + 3*1 = 45    {Distributive property used: a*(b+c) =(a*b) +(a*c)}

3x + 3    = 45

Answer:

Step-by-step explanation:

The graphed data with the line of best fit (attached).

From the graphing calculator, the given line of regression is:

y = 0.125873x - 7.11916

To estimate the minimum hourly wage in 2025:

⇒ x = 2025 - 1900 = 125

Substitute x = 125 into the equation:

⇒ y = 0.125873(125) - 7.11916

⇒ y = 8.614965

Therefore, minimum hourly wage = $8.61 (nearest cent)

What is Continuous Compound Interest?

Continuous compounding is the potentially endless number of periods in which compound interest may be calculated and reinvested into an account's balance.

[tex]\rm A = Pe^{rt}[/tex]

where,

A is the principal amount after t number of years,

r is the rate at which the principal is been compounded, and P is the principal amount.

Given the principal amount of $570 is invested for a period of 10 years, and at a rate of 4% per year, therefore, the worth of the investment after 10 years will be,

[tex]\rm A = \$570 \times e^{(0.04 \times 10)} = \$850.34[/tex]

Hence, the worth of the investment after a period of 10 years will be $850.34.
