Markup =35%
Model train cost =100
So 135%=100
1%=100/135
100%=100/35)*100=74.07
Original cost =74.07
Answer:
t=34.64 mins
Step-by-step explanation:
let Arya be A, Robot be B and Combined time be t
![A+B=\frac{1}{t}\\A=\frac{1}{t+120}\\B=\frac{1}{t+10}\\\frac{1}{t+10}+\frac{1}{t+120}=t\\\frac{1}{t+10}=\frac{t+120-t}{t+120}\\t^2+120t=120t+1200\\t^2=1200\\t=34.6410](https://tex.z-dn.net/?f=A%2BB%3D%5Cfrac%7B1%7D%7Bt%7D%5C%5CA%3D%5Cfrac%7B1%7D%7Bt%2B120%7D%5C%5CB%3D%5Cfrac%7B1%7D%7Bt%2B10%7D%5C%5C%5Cfrac%7B1%7D%7Bt%2B10%7D%2B%5Cfrac%7B1%7D%7Bt%2B120%7D%3Dt%5C%5C%5Cfrac%7B1%7D%7Bt%2B10%7D%3D%5Cfrac%7Bt%2B120-t%7D%7Bt%2B120%7D%5C%5Ct%5E2%2B120t%3D120t%2B1200%5C%5Ct%5E2%3D1200%5C%5Ct%3D34.6410)
Answer:
The general equation of a circle is x2 + y2 - 6x - 16y + 48 = 0
Step-by-step explanation:
Part A:
Given the ratio 1 : 2, we can describe this ratio with the following situation.
The number of green balls to orange balls in the bag is in the ratio of 1 : 2. For every green ball in the bag, there are 2 corresponding orange ball.
Part B:
Given the ratio 29 : 30, we can describe this ratio with the following situation.
The ratio of the amount of sugar used to the amount of salt used to prepare the sugar-salt solution is 29 : 30. For every teaspoons of sugar used in the solution, 30 teaspoons of salt needs to be used.
Part C:
Given the ratio 52 : 12, we can describe this ratio with the following situation.
The
number of kilometers travelled by the car and the bicycle is in the ratio of 52 :
12. For every 52 kilometers travelled by the car, the bicycle travelled 12 kilometers.
