Ok the answer would be x=11
Answer:
900
Step-by-step explanation:
To get your answer, you can just multiply 20 seconds by 3 to get 60 seconds, which is a minute.
Since whatever you do on one side you have to do to the other, multiply 300 mi by 3 as well. That would get you 900.
Answer: 5500cm.
Step-by-step explanation:
A revolution corresponds to circumference of the bicycle wheel.
The radius of the circle = 70/2 since two radii makes a diameter.
Therefore r = 35cm
Circumference of a circle = 2πr or πd where π = 3.142 or 22/7
We now have = 2 x 22/7 x 35
Therefore 0ne revolution = 220cm.
Therefore, the distance traveled by making 25 revolution
= 220 x 25
= 22000/4
= 5500cm.
Answer:
<u>Given the equation </u>
<u>We need:</u>
<u>following</u>
- 20n + 35 ≤ 600
- 20n ≤ 565
- n ≤ 565/20
- n ≤ 28 (rounded to the whole number)
<u>Considering that n ≥ 15, we have:</u>
<u>And the cost is going to be:</u>
- 20*15 + 35 ≤ C ≤ 20*28 + 35
- 335 ≤ C ≤ 595
