16.5 miles?
My line of thinking is:
3miles/2hours=1.5 (3/2)
1.5x11=16.5
Answer:
x = 4 or x = -3
Step-by-step explanation:
Take square both the sides,
x² - x - 12 = 0
x² - 4x + 3x - 3*4 =0
x*(x - 4) + 3*(x - 4)= 0
(x- 4 )(x+3) =0
x -4 =0 or x + 3 = 0
x = 4 or x = -3
Answer:
107 cm
Step-by-step explanation:
2.17 m in cm is 217 cm
2 m is 200 cm
2.07 m is 207 cm
so 107 is the smallest number when all are calculated in cm
The equivalent expression of 14r^4y^6/7r^8y^2 is 2y^4/r^4
<h3>How to determine the equivalent function?</h3>
The expression is given as:
14r^4y^6/7r^8y^2
Start by dividing 14 by 7
2r^4y^6/r^8y^2
Next divide y^6 by y^2
2r^4y^4/r^8
Lastly divide r^4 by r^8
2y^4/r^4
Hence, the equivalent expression of 14r^4y^6/7r^8y^2 is 2y^4/r^4

This problem can be solved two ways. Since the ratio of each side is 3:8, you can use that ratio to calculate the length of each side of the larger triangle and then add them up to get the perimeter. Or you can realize that the perimeter will also have the ratio 3:8 and calculate the perimeter of the smaller triangle and then use the ratio to calculate the perimeter of the larger triangle. Since I'm lazy, I'll be using the second approach.
Perimeter of smaller triangle is 8 + 11 + 14 = 33 cm.
Now we can setup an equation to calculate the perimeter of the larger triangle:
33/3 = X/8
11 = X/8
88 = X
So the perimeter of the larger triangle is 88.</span>
