Answer:

9 and 27

Step-by-step explanation:

Let the smaller number be x.

The larger of two numbers is three times the smaller.

Larger number = 3x

ATQ,

x+3x = 36

4x = 36

x = 9

Smaller number = 9

Larger number = 3x = 3(9) = 27

So, the numbers are 9 and 27.

Answer:

$250

Step-by-step explanation:

The formula for simple interest is I = PRT, where I= interest earned or paid, P = principal deposited or borrowed, R = interest rate as a decimal, and T = time in years.

I = PRT

I = (1000)(0.05)(5)

I = 250

What is D of the arithmetic sequence for which a5 equals 24 and a9 equals 40

Gnom [1K]

In an arithmetic sequence d represent the common difference.

The formula to find the general term of an arithmetic sequence is,

$a_{n} =a_{1} +(n-1)d$

Where $a_{n}$ = nth term and

$a_{1}$ = First term.

Given, $a_{5} = 24, a_{9} = 40$ . Therefore,

$a_{1} +(5-1)d = 24 , a_{1} +(9-1)d = 40$

$a_{1} +4d = 24 , a_{1} +8d = 40$

Next step is to subtract the above equations so that we can eliminate a1 and get the value of d. Hence,

4d - 8d = 24 - 40

-4d = - 16

$\frac{-4d}{-4}= \frac{-16}{-4}$ Divide each sides by - 16.

d = 4

So, d = 4.

Hope this helps yoi!.

Answer:

Step-by-step explanation:

To find the constant of proportionality between y and x, divide $\frac{y}{x}$ for all given values of the chart. If you get the same number, then that is the constant. If they are all different numbers, then one does not exist for that function.
