Aidan took a 1020 km trip, travelling by Bus and By Train. The bus travelled at 105 km/h, and the train travelled at 160 km/h. The whole trip took 8 Hours. How Far did he travel on the train? Solve algebraically, and round your final answer to one decimal place.

Answers

Answer:

  523.6 km

Step-by-step explanation:

Let x represent the distance traveled by train. Then 1020-x is the distance traveled by bus. The travel times are given by the relation ...

  time = distance/speed

Then the total travel time in hours is ...

  x/160 +(1020-x)/105 = 8

  21x +32640 -32x = 26880 . . . . .  multiply by 3360

  5760 = 11x . . . . . . . . . add 11x -26880

  523.6 ≈ x . . . . . . . . . . divide by 11

if i got shorts for 30 dollars and the original price was 40 what was the discount​

Answers

Answer:

25%

Step-by-step explanation:

30/40 = 0.75 = 75% paid

100-75 = 25% discount

Answer:

[tex]25\%[/tex]

Step-by-step explanation:

To find the discount of an object, one must set up the equation, the difference between the original and the paid price, over the original price, equals percent over 100. In essence;

[tex]\frac{(original-paid)}{original}=\frac{percent}{100}[/tex]

Substitute in the given values;

[tex]\frac{(40)-(30)}{40}=\frac{percnet}{100}[/tex]

Solve;

[tex]\frac{10}{40}=\frac{percent}{100}[/tex]

Simplify,

[tex]\frac{1}{4}=\frac{percent}{100}[/tex]

Cross products,

[tex]100 = 4(percent)[/tex]

Inverse operations,

[tex]100=4(percent)\\/4\\\\25 = percent[/tex]

Answers

Answer:

44.2545

Step-by-step explanation:

you can find the third angle by taking 180-(90+55)=a

a=35

use law of sines

Sin(angle)/(opposite side of angle)=Sin(another angle)/(opposite side of another angle)

so, sin(a)/A=sin(b)/B

sin(35)/33=sin(55)/x

x=sin(55)/(sin(35)/33)

x=44.2545

(2x − 7) feet
(7x − 2) feet
