Due to an accident on the highway, the Stanford family is delayed driving to their weekend destination. Their average speed is 30 miles per hour for the first portion of their trip as they come upon the accident site. After passing the accident site, their average speed increases to 50 miles per hour. The Stanford family can express their average speed for the entire trip as 30x+50(x+2)2x+2. What is the meaning of the parts of this rational expression in the context of the situation? Select from the drop-down menus to correctly complete the statements. The numerator of the rational expression represents the Stanford family's Choose... . The denominator of the rational expression represents the Stanford family's

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

q1 a person or thing situated away or detached from the main body or system. a cluster is a a mash of many things.

q2 do

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
