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

Help?????? Does anyone know the answer to this

I think it’s B, or 0.10x+0.15(50-x)=0.12(50)

Because 10% would give you 30ml, and 15% would equal 20ml to get 50ml, according to the equation.

Mr. Drumm is purchasing tickets for a school museum visit. The Museum of Natural History charges a $25 group fee plus $5 per stu
Greeley [361]

Answer:

10 tickets

Step-by-step explanation:

25 + 5x = 35 + 4x

solve for x:

subtract 25 from both sides...

5x = 35 - 25 + 4x

subtract 4x from both sides...

5x - 4x = 10

x = 10, 10 tickets.
