Answer:
30 mi/ 24 mi (6 mi slower)
Step-by-step explanation:
distance = rate x time
distance = 20 mph * X hr = 20 X miles
return trip:
distance = 16 mph * X hr + 6 miles = 16X + 6
They are the same:
20X = 16X + 6
4X = 6
X = 6/4 = 3/2
20 mph * 3/2 hr = 30 miles.
On the return trip: 16 mph * 3/2 hr = 24 miles, which is 6 miles short of 30 mi.
The distance is 30 miles.
The bird flies all 30 miles in 3/2 hr = 1 and 1/2 hour = 1 hour 30 minutes.
On the return trip, the bird flies 24 miles in 1.5 hours, which is 6 miles short.
Answer:
1
Step-by-step explanation:
Hopefully this is correct. say your starting point is {B} and want to go to {A}. clockwise is always to the left and the mark {B} is on a 90 degree angle both ways. so you would need to go 90 degrees clockwise to get around to A.
I am just a middle schooler hopefully this piece of information may help you figure it out.
Answer: B
Step-by-step explanation:
Let's analyze each option:
A) We know all the sides:
Ok, if we know all the sides, we can make only one triangle with it, so this defines only one triangle:
B) We know only the angles, all the angles are the same so this is an equilateral triangle, now we can make infinity equilateral triangles if we change the length of the side, so this criterion makes more than one triangle.
C) We have two angles (so we basically have 3 angles, because all the angles of a triangle must add up to 180°) and one side, so the other two sides are defined already, with this we can make only one triangle.
D) Two sides and one included angle (meaning that this angle goes between the two known sides)
With this, we already can find the missing side and then the complete triangle, so this criterion only defines one triangle.
Answer:
Step-by-step explanation:
( g o h)(x) = g(h(x)) = g(3x) = 1/(3x+2)
( g o h)(x) exisit for 3x+2 ≠ 0
x ≠ -2/3
so the domain is : D = ]-∞:-2/3[ U] -2/3;+∞[
