Write the next whole number after 6748nine in the base-nine system.
ale4655 [162]

Answer:

Step-by-step explanation:

6748_9 = 6 *(9^3) + 7 * 9^2 + 4 * 9^1 + 8 * 9 ^ 0 = 4994_{10}

Hence, on base 10, the next whole number is 4995 and if we convert back to base 9, we will have

6* 9^3 + 7*9^2 + 5*9*1 = 4374 + 576+45 = 4995_{10}

Therefore, the number on base 9 will be 6750

The length of a rectangle is 5 less than 3 times the width. What is the length?
Tanzania [10]

Answer:

Let the width of the Rectangle be x inches

Then, length is (3x-5) inches

Perimeter of the Rectangle= 46 inches (given)

According to the above problem,

Equation :---- Perimeter=2(length+breadth)

<u>2{(3x-5)+x}=46</u>

2(4x-5)=46

(4x-5)=46/2=23

4x=(23+5)=28

x=28/4

<u>x=7</u>

So, length of the Rectangle is {(3×7)-5}=16 inches

and width is= 7 inches
