The first number is 36 and the second number is 12.

Let x be the first number and y be the second number.
The sum of them is 48; therefore x+y=48.

Increasing the first number 3 times is 3x.  Increasing the second number 9 times is 9y.  When we do this, they are equal, so 3x=9y.  We will solve for x so we can use substitution:

3x=9y
3x/3 = 9y/3
x=3y

Now we will substitute this into our first equation:
3y+y=48
4y=48

Divide both sides by 4:
4y/4 = 48/4
y = 12

In a survey, a group of students were asked to name their favorite day of the week. There were 8 students who chose “other”.
lara [203]
5 % of the students choose other. 95% choose either Saturday or Sunday. 
Let x be the number of students who participated.

(5/100) * x = 8  Multiply both sides by 100
5 * x = 8*100
5*x = 800  Divide by 5
x = 800/5
x = 160 students participated in the survey <<<<< Answer

find the total amount and total interest after eight months if the interest is compounded every four months
Volgvan

The total amount is $ 6050, and the total interest after 8 months is $1050.

What is interest?

  • Interest is the financial charge for the honor of adopting a plutocrat, generally expressed as a periodic chance rate( APR).
  • Interest is the quantum of plutocrat a lender or fiscal institution receives for advancing out money. However, you do it in order to achieve that result or maintain that situation, If you do commodity in the interests of a particular result or situation.
  • There are basically three(3) main types of interest rates the nominal interest rate, the effective rate, and the real interest rate.
  • The nominal interest of a (one) investment or loan is simply the stated rate on which interest payments are calculated.

Here,

Period per year = 124 = 3

Total amount = amount  (1 + periodic rate)period

          = $6,050

Total interest = Total amount - amount

          = 6050 - 5000

          = $1,050

Thus,

The total amount is $ 6050, and the total interest after 8 months is $1050.

Question 3: 12 points
Dvinal [7]

Answer:

9x^{5}y^{5} yards.

Step-by-step explanation:

Given that the area of a rectangle (A) is 45x^{8}y^{9} square yards.

If the length of the rectangle (L) is given to be 5x^{3}y^{4} yards, then we have to find the width (W) of the rectangle in yards.

Now, A = L × W

⇒ W = \frac{A}{L} = \frac{45x^{8}y^{9}}{5x^{3}y^{4}} = (\frac{45}{5})\times (\frac{x^{8}}{x^{3}}) \times (\frac{y^{9}}{y^{4}}) = 9x^{8 - 3}y^{9 - 4} = 9x^{5}y^{5} yards. (Answer)
