Answer:
250 miles
Step-by-step explanation:
So we know that the time (t) equals 5 hours and that the rate (r) equals 50 mph. So knowing that, we can use the formula t*r=distance. We plug in the numbers and we get 250 miles.
Another way to think about this is, since we go 5 hours and 50 miles per hour, every hour we go 50 miles and we do that for 5 hours, so we go 50, 100, 150, 200, 250.
Y=3/4x-2 would be your equation :)
You find this with y=mx+b with m being your slope and b being the y-axis point
If you would like to solve the quadratic function by completing the square, you can do this using the following steps:
- 32 = 2(x^2 + 10x)
- 32 + 50 = 2(x^2 + 10x + 25)
18 = 2(x + 5)^2
9 = (x + 5)^2
<span>± sqrt(9) = x + 5
</span><span>± 3 = x + 5
</span>x = - 2 or x = - 8
Given :
∆GHI is an isosceles triangle with a vertex angle H.
m∠H=80°
To Find :
The m∠I.
Solution :
Since, H is the vertex angle.
So, m∠I = m∠G = x
We know, by angle sum property of triangle :
m∠I + m∠G + m∠H = 180°
2x + 80° = 180°
x = 50°
Therefore, m∠I = 50° .
Given : 2D + 1L = 100,
And D + L = 70
This is a simultaneous equation can be solved as follows
2D + L = 100
- D - L = -70
————————————-
D - 0 = 30
i.e D (number of dudes) = 30
Therefore, since we already know the fraternity sold 70 tickets in total,
70 -30 = 40 (the number of ladies attended)
