Answer: 232 pages
Step-by-step explanation:
Total digits = 588
1 digit page number:
1 to 9 = 1 × 9 = 9
Number of pages = 9/1 = 9
2 - digit page number :
10 - 99 = 2 × 90 = 180
Number of pages = 180/2 = 90
3 - digit page number :
588 - (9 + 180) = 588 - 189 = 399
Number of pages with 3 - digits = 399/3 = 133
Therefore, the total number of pages the book has is :
(9 + 90 + 133) = 232 pages
Equation is (x+2)^2 - x^2 = 7676
solve the equation by first opening the bracket of (x+2)^2 by A^2 + 2AB +C^2
you'll end up with 4x + 4 = 7672
thus x = 1918 and the next number is 1920.
Answer:
$690
Step-by-step explanation:
The amount she makes in a week=her weekly salary + the commission on sales.
Amount=330 + 7.5% of 4800.
Amount = 330+ 360=690.
The she would make if she sold $4,800 of merchandise is $690.
Answer:
Length = 30m and Breadth = 10m
Step-by-step explanation:
Given that :
Perimeter = 80 m ;
Breadth = 1/3 of Length ; Length = l
We know that :
Perimeter of rectangle = 2 ( L + B ).
80 = 2 ( L + 1/3 L )
80/2 = 4/3 L.
40 = 4/3 L
3/4 × 40 = L.
3 × 10 = L.
L = 30m.
Breadth = 1/3 of Length.
Breadth = 1/3 × 30.
Breadth = 10m.
