Answer:False, there are 204!
Step-by-step explanation:
In order to answer this question, we use the concept of ratio and proportion wherein we use the equation,
R1 / T2 = R2 / T1
where R is for rate and T is for time. Substituting the known values to the equation,
(600)/x = (400)/ 20
The value of x from the equation is 30. Thus, it will take 30 hours if the rate was adjusted to 400 gallons per minute.
A = s²
A = area
s = length of each side of the square
*take square root of both sides
s = √A
s = √125 sq. mi.
s = 11.18 miles
*rounded to nearest mile
s = 11 miles
If 1 classroom uses 16 sections, then 6 classrooms would use :
6 * 16 = 96 sections
and 14 classrooms would use : 14 * 16 = 224 sections
Answer: -1+6y+7x
To simplify expressions, you have to be able to combine like terms (eg. 3x and 2x to get 5x). Since there are none in this expression, and you can't combine y and x, this expression can't be simplified.
*If it helps, think of x and y as different types of candy... ;3
For example, you can't combine 12 Skittles (x) and 4 Reese's (y), because they aren't the same. So, you'd write that you have 12 Skittles and 4 Reese's.
