Step-by-step explanation:
or 0.167 pounds more butter was used than sugar
<em><u>Solution:</u></em>
Given that, Desmond's Desserts made a batch of fresh scones with 2/3 of a pound of butter and 1/2 of a pound of sugar
<em><u>To find: Amount of butter used than sugar</u></em>
From given information,
![\text{Butter used} = \frac{2}{3} \text{ pound }](https://tex.z-dn.net/?f=%5Ctext%7BButter%20used%7D%20%3D%20%5Cfrac%7B2%7D%7B3%7D%20%5Ctext%7B%20pound%20%7D)
![\text{Sugar used } = \frac{1}{2} \text{ pound }](https://tex.z-dn.net/?f=%5Ctext%7BSugar%20used%20%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctext%7B%20pound%20%7D)
To find how much butter is used than sugar, find the difference between them
![Difference = Butter\ used - Sugar\ used](https://tex.z-dn.net/?f=Difference%20%3D%20Butter%5C%20used%20-%20Sugar%5C%20used)
![Difference = \frac{2}{3} - \frac{1}{2}\\\\Difference = \frac{2 \times 2-1 \times 3}{3 \times 2}\\\\Difference =\frac{4-3}{6}\\\\Difference =\frac{1}{6} = 0.167\\\\](https://tex.z-dn.net/?f=Difference%20%3D%20%5Cfrac%7B2%7D%7B3%7D%20-%20%5Cfrac%7B1%7D%7B2%7D%5C%5C%5C%5CDifference%20%3D%20%5Cfrac%7B2%20%5Ctimes%202-1%20%5Ctimes%203%7D%7B3%20%5Ctimes%202%7D%5C%5C%5C%5CDifference%20%3D%5Cfrac%7B4-3%7D%7B6%7D%5C%5C%5C%5CDifference%20%3D%5Cfrac%7B1%7D%7B6%7D%20%3D%200.167%5C%5C%5C%5C)
Thus
or 0.167 pounds more butter was used than sugar
Answer:
r = 19.2deg
Step-by-step explanation:
6r + 5 = 30 + 90 (exterior angles of a triangle)
6r = 115
r = 19.2deg (1dp)
