The answer is B. because it is 6:9 which simplifies down to 1:3
Answer:
c = price of child ticket = $4.25
a = price of adult ticket = $4.25 + $1.00 = $5.25
Step-by-step explanation:
A child ticket costs c and an adult ticket costs a = c + 1.
21 children pay c dollars each for admission, and
3 teachers pay c + 1 dollars each for admission.
Thus,
21c + 3(c + 1) = $105, and
21c + 3c + 3 = $105, so that:
24c = $102
c = price of child ticket = $4.25
a = price of adult ticket = $4.25 + $1.00 = $5.25
Answer:
c cause it says length = 5x
Since the measures of the two angles are in the ratio 8:1, this means the bigger angle's is 8x and the smaller angle is x. Since they are complementary, they add to 90°, so you create the equation 8x+x=90°. This can be simplified to 9x=90°. Then, you divide 90 by 9 to get 10. This means x=10. Next, you replace x with 10 to find the measure of the bigger angle. 8x10=80, so the larger angle is 80°.
