Answer: biggest no.=27. Smallest number=9

Step-by-step explanation:

Let's take the smallest number as x and the biggest number as 3x since it is 3 times bigger than x.

The sum of these two numbers is 36

3x+x=36

4x=36

X( smallest number)=36/4: 9

While, the biggest number is 3x: 3×9=27

The length of a rectangle is 3cm greater than its width. the perimeter of the rectangle is 34cm. find its length.

mamaluj [8]

Answer:

10cm

Step-by-step explanation:

The formula for perimeter is:

$P=2(l+w)$

Let the width of the rectangle be x then the length would be...

3+x

Now, let's plug these values into the equation and solve. (Note we are also given perimeter is 34 cm):

$34=2(x+3+x)\\34=2(2x+3)\\Distribute\ the\ 2\ to\ each\ term\ in\ the\ parentheses\\34=2(2x)+2(3)\\34=4x+6\\Subtract\ 6\ from\ both\ sides\\4x=28\\Divide\ both\ sides\ by\ 4\\x=7$

And since the length is x+3 then it is...

x+3=7+3=10cm

Result:

The interest is $1749.6 and the amount is $4449.6.

Explanation:

STEP 1: Find an interest by using the formula , where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.

In this examplee P = $2700, i = 64.8% and t = 1 years, so

STEP 2: Find an amount by using the formula .A =P+I

Since P = $2700 and I = $1749.6 we have
