Answer:

y = 5x

Step-by-step explanation:

Assuming you require the proportional equation

Given that y is directly proportional to x then the equation relating them is

y = kx ← k is the constant of proportion

To find k use the condition when y = 30, x = 6 , then

30 = 6k ( divide both sides by 6 )

5 = k

y = 5x ← equation of proportion

The Science Club went on a two-day field trip. The first day the members paid $60 for transportation
AlladinOne [14]

Answer:

day 1 total $60+$15=$75

day 2 total $95+$12=$107

total 2 days = $181

Step-by-step explanation:

Answer:

Total cost for two days for the n members of the club = 155 + 27 n

Step-by-step explanation:

Total number of persons = n

The first day the members paid $60 for transportation plus $15 per ticket to the planetarium.

Day 1 cost = 60 + 15 x n = 60 + 15 n

The second day they paid $95 for transportation plus $12 per ticket to the geology museum.

Day 2 cost = 95 + 12 x n = 95 + 12 n

Total cost = Day 1 cost + Day 2 cost

Total cost = 60 + 15 n + 95 + 12 n = 155 + 27 n

Total cost for two days for the n members of the club = 155 + 27 n

On Sunday, Ben goes to a velodrome to train. He cycles the first lap of the track in 25 seconds Each lap Ben cycles takes him 16
daser333 [38]

Answer:

169 seconds

3rd lap

0.923 minutes

Step-by-step explanation:

To solve this question, we would use formula for arithmetic progression in solving it.

S(n) = a + (n - 1)d

If a = 25 s

n = 10

d = 16

S(n) = 25 + (10 - 1)16

S(n) = 25 + 9 * 16

S(n) = 25 + 144

S(n) = 169

It takes him 169 seconds to cycle his tenth lap

b

If S(n) = 55.4, what is n

55.4 = 25 + (n - 1)16

55.4 - 25 = (n - 1)16

30.4 = (n - 1)16

n - 1 = 30.4/16

n - 1 = 1.9

n = 1.9 + 1

n = 2.9 approximately 3

Therefore, he's on his 3rd lap

c

Total time cycled is dependent on the total cycles he made, and going to question 2, we were told he made 55.4 seconds of cycle

55.4/60 = 0.923 minutes

PLEASE HELP WILL GIVE BRAINLIEST
tatyana61 [14]

The formula is pi r squared so

10 is the diameter and you need the radius so divide the diameter in half to get 5 then plug it into the equation so the equation should be pi 5 squared

Then you square 5 to get 25 so now you have

3.14(for pi) x 25

And the answer is 8.746913126...

And the final answer is about

8.7 meters squared

I hope I could help
