At first glance, it seems like a good estimate; big numbers make bigger number.
But, this is multiplication, which means big numbers will make an extraordinarily big number, in proportion to the numbers themselves.
If you round 31 3/4 up to 32, you can multiply that by 50. To make the estimate easier, multiply 50 by 2,
50 x 2 = 100
Take the zeros off 50 and 30 to make this a bit simpler, and multiply 5 by 3,
5 x 3 = 15
Add each of the zeros you took off to the 15 to make 1500 (1 zero was taken off 50, and 1 off of 30),
And then add 1500 to that other 100
1500 + 100 = 1600
A good estimate for 50 x 31 3/4 would be 1600, not 800.
Therefore,
No. Brenda's estimate of 800 is NOT a good estimate.

Answer:
Step-by-step explanation:
<u>Let functions be</u>
- Jada = f(j)
- Diego = f(d)
- Lin = f(l)
<u>As per given ratios:</u>
- f(d) = 2f(l)
- f(j) = 2f(d) ⇒ f(j) = 4f(l)
The smallest slope belongs to f(l), greater - f(d), the greatest - f(j)
Possible graphs reflecting the functions are graph 1 and graph 3
Answer:
6 green fish
Step-by-step explanation:
green fish = x
(X+3)/60 = x/40
Cross multiplication
60x = 40x+120
subtract 40x on both sides
20x = 120
Divide both sides by 20
x=6
The aquarium has 3 more yellow fish than green fish 6+3 = 9 (9 yelow)
15 fish in total
60% of 15 = 9
40% of 15 = 6
