You have two 30-60-90 triangles, ADC and BDC.
The ratio of the lengths of the sides of a 30-60-90 triangle is
short leg : long leg : hypotenuse
1 : sqrt(3) : 2
Using triangle ADC, we can find length AC.
Using triangle BDC, we can find length BC.
Then AB = AC - BC
First, we find length AC.
Look at triangle ACD.
DC is the short leg opposite the 30-deg angle.
DC = 10sqrt(3)
AC = sqrt(3) * 10sqrt(3) = 3 * 10 = 30
Now, we find length BC.
Look at triangle BCD.
For triangle BCD, the long leg is DC and the short leg is BC.
BC = 10sqrt(3)/sqrt(3) = 10
AB = AC - BC = 30 - 10 = 20
Answer: a. The unit for the numerator is Dollars
b. The unit for the denominator is seconds.
Answer:
The total length of the trip was 400 miles.
Step-by-step explanation:
He fell asleep at 44% through the trip, they already had traveled 176 miles.
.44x = 176 ⇒
176 ÷ .44 ⇒
x = 400

The first thing you should do for this case is to find the equation of the line that best suits the problem and then plot it.
Let X: number of months and: amount paid.
The equation of the line is
y = 15x + 25 y-intercept = 25
the slope = 15
Answer:
Georgie pays (y axis) $ 15 dollars (the spole) monthly (x-axis) in the gym with a $ 25 registration (y -intercept)
