Estimated answer is 4000 and actual answer is 3901
Step-by-step explanation:
- Step 1: Estimate 47 × 83 by rounding off to the nearest 10.
⇒ 47 ≈ 50 and 83 ≈ 80
⇒ 50 × 80 = 4000
- Step 2: Do the actual calculation of 47 × 83
47
× 83

Question 2
Note: Let t = theta since I there is no theta symbol on my keyboard.
(0, -1) = (cos t, sin t)
cos t = 0
sin t = -1
I read the answer from the given point.
On the unit circle, the point (0, -1) lies at 3pi/2. So, angle theta is 3pi/2.
tan t = sin t/cos t
tan t = cos t ÷ sin t
Therefore, tan t = what?
You finish....
I would belive its great because if you have 4/5 of a pie compared to 7/12 of a pie having 4/5 would be more of the pie , I hope that helped that's how I have to think about fractions
