Answer:

We must think that the cars are traveling 630 miles in six hours.

Their combined speeds are x and x+25.

distance = velocity * time

Since, velocity = distance / time

(x + x + 25) = 630 / 6

2x + 25 = 105

2x = 80

So x = 40 mph  and the other car's velocity is 65 mph.

Feliz [49]

Answer:

y=6x+25

Step-by-step explanation:

y will be the whole cost. 6 is how many sessions you have and x is the cost of each of those sessions. The one time introduction fee is 25. you would add 25 plus 6 times the cost of sessions (x) and you would get your answer (y).

Please help I'm clueless! I'll give brainliest!

Answer:

33%

Step-by-step explanation:

The logo can be divided into three...

1. The inner circle (or The White Circle)

2. Blue + White circle

3. The whole circle(The logo)

I will be calculating the area of each circle..

Area of circle = (pi)r²

pi = 22/7

The inner circle

radius = 4cm

Area = 22/7 × 4²

= 50.286 cm² or 50²/7 cm²

Blue + White Circle

radius = 4 + 3 = 7cm

Area = 22/7 × 7²

= 154 cm²

The whole circle

radius = 4 + 3 +3 = 10cm

Area = 22/7 × 10²

= 314.286 cm² or 314²/7 cm²

Area shaded blue =

Area of [(Blue + White circle) - (The white circle)]

= 154 - 50.286 = 103.714 cm² or 103.⁵/7 cm²

Percentage of logo shaded blue =

(Area shaded blue) / (Area of logo) × 100

= 103.714/314.286 × 100

= 32.9999%

= 33%
