Answer:The answer can be calculated by doing the following steps;
Step-by-step explanation:
Answer:
f = - 324
Step-by-step explanation:
Given
= - 162
Multiply both sides by 2 to clear the fraction
f = 2 × - 162 = - 324
4.05400 is hopefully the answer
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.
3 is how many wool you need for 8 caps because each cap uses 0.5 wool so add it all up or like multiplication so 0.5 X 8 = 4 0.5 X 6 = 3
