Answer: 28 Brownies and 38 Cookies
Let say the brownies sold for B amount and cookies for C amount. There were 10 more cookies sold than brownies. If brownies sold X piece then, total sales would be:
Sales: (X+10) C + XB
Total sales is $40. Cookies sold for $0.50 each. Brownies sold for $0.75 each. If you insert it all to the first equation, it would become:
$40= (X+10) x $0.50 + $0.75X
$40= $0.50X + $5 + $0.75X
40= 1.25X + 5
1.25X= 35
X= 35 / 1.25= 28
Brownies sold at 28 pieces. Cookies sold at: 26+10= 38 pieces.
Answer:
In a Euclidean space the sum of a triangles angles are always 180 degrees
45 + 80 = 125
180-125 = 55
So the answer is 55 degrees

Answer:
a) 0.437; b) 0.291
Step-by-step explanation:
For part a,
There are 280+210 = 490 people that are over 18 years old. Out of these, 119+95 = 214 purchase 2 pairs of jeans annually. This is
214/490 ≈ 0.437
For part b,
There are 87+69+74+11 = 241 people who purchase 3 or more pairs of jeans. There were a total of 220+290+280+210 = 1000 people; this means there were 759 people tho purchased fewer than 3 pairs of jeans.
Out of these, 21+74+126 = 221 were in the age group 12-18. This gives us
221/759 ≈ 0.291
