Answer:
The place value to which the number is rounded is unit place.
Step-by-step explanation:
Here, the number 3.695 is rounded to the number 4 and we have to name the place value to which the number is rounded.
Here, the place value to which the number is rounded is unit place.
And the name of the rounding is the rounding to the nearest whole number i.e. there will be no fractional part in the rounded number.
Another example is the number 0.917 is rounded to the nearest whole number to give 1. (Answer)
Answer: D) Length: 60, Width: 30
Step-by-step explanation:
The totals of the length plus two widths of the other dimensions given do not add up to 120 feet.

let's recall that the conjugate of any pair a + b is simply the same pair with a different sign, namely a - b and the reverse is also true, let's also recall that i² = -1.

Answer:
a. 14,000
b. 140,000
Step-by-step explanation:
Let the three consecutive number be x,x+1 and x+2.
It is given sum of three consecutive numbers is 46.
So,x+x+1+x+2=46
3x+3=46.
Subtracting 3 both sides
3x=46-3
3x=43.
x= 
Since is not an integer there is no true answer to this problem.
