Let the speed of the current be x and the speed of the canoe in still water be y, then
Adding the two equations, we have:
From any of the equations, we have that x = 2
Therefore, the speed of the current is 2 miles per hour while the speed of the canoe in still water is 5 miles per hour.
(1/8) / (3/4) =
1/8 * 4/3 =
4/24 reduces to 1/6 <===
If he decides to save 10% he decided to save 38.75 since 387.50×.10 is 387500 (move decimal 4 times to figure out what the percentage of 387.50 is since the $ already has 2 numbers after the decimals and so does .10 which =38.75 this is what he saves so subtract this from 387.50 to find out what he has left to spend
387.50-38.75= 348.75
Alright sure:
Q5: ∠3
Q6: ∠1
Q7: ∠2
Q8: x = 25
Q9: x = 63
For Questions 8 and 9 what I did was find out the supplementary angle adjacent to the exterior angle.
8: 180° in a supp. angle. So 180-105 = 75. To make a triangle it has to be 180°. So 180 - 75-80 = 25 So x=25
9: 180° in a supp. angle. So 180-135 = 45. To make a triangle it has to be 180°. So 180 - 45-72 = 63. So x=63
Let me know if you don't understand that. If you don't get it I'll explain it further for you.
Since this can't happen, let's suppose that P=150, then:
Now we have to move the 100 to the other side of the equation with a negative sign to get this:
Finally, to get w, we move the 2 that's multiplying to the other side dividing the 50:
Therefore, the width of the rectangle would be 25 ft if the perimeter is 150ft, and we can see how the rectangle would look:
