Answer:
43/4 = 10.25 which rounds to the nearest whole number of 10 total carts
Answer:
A, B, C, D
Step-by-step explanation:
A is equal to 54, B is equal to 23, C is equal to 72, and D is equal to 84.
They could look at the weight(take into consideration if the book is paperback or hardcover), the length, and the size of the font to estimate the size of the book.
I will help you do it not give the answer,
Ok so we draw a frequency table by like say if we have 3 2’s then we add a column of like 0-5 and say like 3 frequencies,
I know it’s confusing at first but just keep trying
And to find average we add all the numbers and we divide by how many numbers there are.
Hope it helps!
If it doesn’t I will explain again.

Answer:
81
Step-by-step explanation:
Let the digits that make up the number be a and b.
Given that the square root of the number is equal to the sum of the digits.
Then,
√(10a + b) = a + b
Also given that the square root of the number is less than the number obtained by interchanging the digits by 9, then
√(10a +b) + 9 = 10b + a
Since √(10a + b) = a + b, then
a + b + 9 = 10b + a
a - a + 9 = 10b - b
9b = 9
b = 1
since √(10a + b) = a + b
√(10a + 1) = a + 1
10a + 1= (a + 1)²
10a + 1 = a² + 2a + 1
a² + 2a - 10a + 1 - 1 = 0
a² - 8a = 0
a(a - 8) = 0
a = 0 or a = 8
Using a = 8 and b = 1,
the number 10a + b = 10(8) + 1 = 81.
