218.16 to the nearest tenth would be 218
Answer:
- $52
- this estimate is a little low
Explanation:
a) I might choose 6 1/2 hours and $8 per hour, so the estimated earnings would be ...
6(8) +(1/2)(8) = 52 dollars . . . . estimated earnings
These values are purposely chosen so that one is a little high and the other is a little low, hopefully producing a closer estimate than if both numbers were high (as 7 hours, $8, for example).
__
b) Using 800 instead of 790 means the pay estimate is about 1/80 = 1.25% high.
Using 6 1/2 instead of 6 3/4 means the hours estimate is about 1/27 ≈ 3.7% low.
So, we expect the product of these values to be slightly low, perhaps by about 2.5%.

<em>Comment on estimating</em>
If you can estimate the error in the estimate with some reasonable accuracy, you can use that to adjust the estimate to a pretty close value.
Step-by-step explanation:
- -12=12i^2, 5
- -12-=12i^2*i^2
- 12(-4)=-48=48i^2
- -12(-5)=60
Lets write this out:-
z² + z + 4z³ + 4z²
z² will become 1z² because when ever there is a varaible, and before it there is NO coefficient the coefficient automatically becomes 1. Same is with z. z will be come 1z.
Lets write it out again:-
1z² + 1z + 4z³ + 4z²
Combine like terms:-
1z² + 1z + 4z³ + 4z²
(1 + 4)z² = 5z²
1z + 5z² + 4z³
So, when combining like terms in z² + z + 4z³ + 4z² the answer is
1z + 5z² + 4z³.
Hope I helped ya!! xD
