Answer:
You count how many significant figures there are and because it's division you see which one has the least amount. 1.3 only has two significant figures so the answer will only have 2 sig figs. So, 21.3 divided by 1.3 equals 16.385 but the answer is 16 because you only include 2 sig figs because that's how many are in 1.3. 21.3/1.3=16
The slope in fraction form is -9/4 so converted to a decimal is -2.25

Step-by-step explanation:
Answer:
$360.
Step-by-step explanation:
The interest earned on principal P, at the rate of r for the duration of t years is given by the equation I = Prt ........... (1)
Now, we have to calculate the interest earned on $3000, at the rate of 0.04 for 3 years.
Here, P = $3000, r = 0.04 and t = 3 years.
Hence, from equation (1), Interest earned, I = 3000 × 0.04 × 3 = $360 (Answer)
