Answer 1
Answer:

Answer:

C and most likely A

Step-by-step explanation:
Answer 2
Answer: A) The equation is proportional.

If the equation forms a straight line on a graph, having a slope that is neither zero or infinity, it is proportional.

B) The equation has a positive y-intercept.

The y intercept in the equation is variable b. Since the equation has +10, it is positive.

Hope this is correct and that it helps✨❤️

At the movie theatre, child admission is $6.10 and adult admission is $9.20 . On Thursday, three times as many adult tickets as child tickets were sold, for a total sales of $707.70 . How many child tickets were sold that day?

Answers

Answer:

21 child tickets.

Step-by-step explanation:

Let x represent number of adult tickets and y represent number of child tickets.  

We have been given that on Thursday, three times as many adult tickets as child tickets were sold. We can represent this information in an equation as:

x=3y...(1)

We have been given that at a the movie theater, child admission is $6.10 and adult admission is $9.20.The all tickets were sold for a total of $707.70. We can represent this information in an equation as:

9.20x+6.10y=707.70...(2)  

Upon substituting equation (1) in equation (2), we will get:

9.20(3y)+6.10y=707.70  

27.6y+6.10y=707.70

33.7y=707.70

(33.7y)/(33.7)=(707.70)/(33.7)

y=21

Therefore, 21 child tickets were sold on Thursday.

In triangle ABC, the measure of angle B is 90 degrees, BC=16, and AC=20. triangle DEF is similar to triangle ABC, where vertices D, E, and F corresponds to vertices A, B, and C, respectively, and each side of triangle DEF is 1/3 the length of the corresponding side of triangle ABC. what is the value of sinF?(please show your work)

Answers

 The third side of triangle ABC is AB. Using the Pythagorean Theorem, its length is 12. 
12² + 16² = 20² 

∠F is congruent to ∠C and so the sin(∠F) = sin(∠C) 

The sin(∠C) = opposite/hypotenuse 
= |AB| / |AC| 
= 12/20 
= 3/5 
= 0.6 

So the answer is 0.6.
