1) Write the equation (27=x(4+5)).
2) Simplify (27=9x).
3) Divide by 9 (x=3).
4) Multiply by 5 (3×5=15).
The answer is there are 15 girls in Liza's classroom.
Answer:
16.082
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
Angle ACE = DCE since they are vertical angles
Angle A = Angle E parallel lines cut by a transversal form congruent alternate interior angles
Angle B = Angle D parallel lines cut by a transversal form congruent alternate interior angles
When all three angles are equal, the triangles are similar.
We can use ratios to find DE
DE CE
------- = ----------
AB AC
DE 8
------- = ----------
12 10
Using cross products
10 DE = 8*12
10 DE = 96
Divide by 10
DE = 9.6
Answer:
75%
Step-by-step explanation:
The image is 4 : 3 = 12 : 9. It is displayed on a screen that is 16 : 9, so it occupies 12/16 = 3/4 of the screen.
75% of the screen area is occupied
