Answer:
180
Step-by-step explanation:
1. Write a proportion.
=
2. Cross multiply.
6x60=360
360/2=180
x=180
OR
1. Write a proportion.
=
If you look at the bottom, since 2 times 30 is 60, 6 times 30 is 180, making the fractions equal.
Y = 1/2x - 5
We know the slope to be 1/2 because lines that are parallel have the same slope. Then we can solve using slope-intercept form and the known point.
y = mx + b ----> Input known values
-2 = (1/2)(6) + b ---> Multiple
-2 = 3 + b ----> Subtract 3 from both sides
-5 = b
Now we can use the y-intercept found and the slope to write the equation above.
The answer is C. 75. Hope this helps.
Add the velocities together since they are in opposite directions
113+87 = 200mph
600 = 200t
600/200 = t
t = 3 hours
Answer:
10 ft
Step-by-step explanation:
perpendicular (p)= 6 ft
base(b) =8 ft
hypotenuse (h) = ?
we know by using Pythagoras theorem
h = 
= 
= 10 ft
hope it helps :)
