Answer:
27/9 is so good! What do you mean you are not sure?
The answer is b2 = 2A/h - b1
A = 1/2(b1 + b2)h
Multiply both sides by 2:
2 * A = 2 * 1/2(b1 + b2)h
2A = (b1 + b2)h
Divide both sides by h:
2A/h = (b1 + b2)h/h
2A/h = b1 + b2
Subtract b1 from both sides:
2A/h - b1 = b1 + b2 - b1
2A/h - b1 = b2
Answer:
The name of the structure is ethyl acetate with one double bond. The attached document contains the structure of the compound
Step-by-step explanation:
¹H NMR =δ4.07(quartet), 1.97( singlet), 1.18(triplet)
2H 3H 3H
¹³C NMR = δ 170, 60, 20, 10 ppm
from the molecular formula,C₄H₈O₂ and spectrum study, the structure of the compound will have a double bond which is calculated as DU= 4+1-(8/2)= 1
thus, the name of the compound as drawn in the attachment is ethyl acetate
Based on the amount of federal taxes withheld till date, the percent of Mary Brown's year-to-date that have been withheld is A. 10%.
The percent of the gross pay that has been withheld for all taxes and voluntary dues is C. 17%.
<h3>How much federal taxes have been withheld?</h3>
= Fed tax till date / YTD Gross
= 662.26 / 6,318.17
= 10%
<h3>How much taxes and voluntary dues have been withheld?</h3><h3 />
= (Fed tax + ST Tax + Med tax + Vol Due) / Current gross
= (111.42 + 17.09 + 12.25 + 2.5) / 845.10
= 17%
