This is because integers is a subcategory of rational numbers, so there are other rational numbers that aren't integers.
Answer:
401 shirts
Step-by-step explanation:
1203 divided by 3 equals to 401
(-1.2,-2.0) and (1.9,2.2) are the best approximations of the solutions to this system.
Option B
<u>Step-by-step explanation:</u>
Here, we have a graph of two functions from which we need to find the approximate value of common solutions. Let's find this:
First look at where we have intersection points, In first quadrant & in third quadrant.
<u>At first quadrant:</u>
Draw perpendicular lines from x-axis & y-axis from this point . After doing this we can clearly see that the perpendicular lines cut x-axis at x=1.9 and y-axis at y=2.2. So, one point is (1.9,2.2)
<u>At Third quadrant:</u>
Draw perpendicular lines from x-axis & y-axis from this point. After doing this we can clearly see that the perpendicular lines cut x-axis at x=-1.2 and y-axis at y= -2.0. So, other point is (-1.2,-2.0).
20,000 Hz = 2 × 10^4 Hz
150,000 Hz = 1.5 × 10^5 Hz
Answer: 10
Step-by-step explanation: subtract 5 by 45 to get 40 then divide 4 to get 10
