Answer:
For the raging river you multiply
X * 9 = Y
And for paddlers the equation is
X + 40 = Y
Answer:
252
Step-by-step explanation:
The number of integers from 100 to 999 is 999 - 100 +1 = 900.
Consider the number of three-digit integers that <em>do not contain 4 </em>as a digit.
For the <em>hundreds</em> digit, there are 8 possible choices (excluding 0 and 4).
For the <em>tens digit</em>, there are 9 possible choices (excluding 4).
For the <em>ones</em> <em>digit,</em> there are 9 possible choices (excluding 4)
Thus, there are 8 × 9 × 9 = 648 three-digit integers without a 4.
The number of three-digit integers with at least one 4 is 900 - 648 = 252.
Answer:
0.5401
Step-by-step explanation:
Because the scientific notation indicates that you have to multiply 5.401 by 0.1, that's all you have to do to get it back to standard notation. 5.401*0.1= 0.5401
Answer:
It will take 17 years to get a population of 42,800. (Specifically 17.3)
Step-by-step explanation:
We will use the equation
y = population
x = amount of years
y = 20000(1 + 0.045)^x
20000 is the original population.
(1 + 0.045) is the increase of 4.5% every year
Answer:
9.5
Step-by-step explanation:
Well the constant proportionality is 9.5 because that is what makes p directly proportional to a, because when h increases, a increases, and when h decreases, a decreases.
