(5 points) the quantity of price measured in dollars depends on the quantity of time measured in minutes. the quantity of time measured in minutes depends on the quantity of price measured in dollars. the quantity of time measured in minutes depends on the quantity of speed measured in calls per minute. the quantity of speed measured in calls per minute depends on the quantity of time measured in minutes.

10

step-by-step explanation:

7+3=10

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

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.
