A- scalene would be the answer as a scalene triangle has 3 unequal sides.
Let the length of the altitude be x, then
x / 13 = 11 / x [taking account the similarity of the two formed triangles]
x^2 = 13 x 11 = 143
x = sqrt(143)
Answer:
a = 2
Step-by-step explanation:
First of all you should remove parentheses by using distribution
24 + 5a = - a + 30a - 24
Then you should collect all like terms
24 + 5a = 29a - 24
After you should move the terms so the variables are only on one side.
5a - 29a = -24 - 24
Collect like terms
-24a = -48
After dividing both sides you get
a = 2
299+399
399+299
200+99+300+99
99+200+99+300
Answer:
3.019 hours.
Step-by-step explanation:
In this case they ask us to calculate the time in hours that are in those distances, for this we have the speed and the distance, we know that speed is equal to:
v = d / t
therefore the time would be:
t = d / t
we must pass the distance that is in kilometers to miles, like this:
350 km * 1 mile / 1.61 km = 217.4 mi
Now if replacing:
t = 217.4 / 72 = 3.019
Therefore, the time would be 3.019 hours.
