Answer:
20% =1/5
1/5 out of 25= 1/5*25/1=25/5=5
So 5oz -amount of ounces of alcohol in solution.
Solution is then 5oz alcohol + 20oz water =25oz
Add 50oz water
25(already existing) + 50 =75oz New solution
Still only 5oz of alcohol
5/75 =0.06666
Convert to percentage by multiplying result with 100.
Answer: 6.666%
The Answer is D. 16.
XZ = 8/sin 30
Answer:
C. RTS
Step-by-step explanation:
When two triangles are congruent, they will have congruent vertices, like each vertex has a partner.
Take a look at the shape of the triangle.
If you look at the triangle on the right, you can see it is almost like a right triangle.
"R" is at the right angle. "S" is on the short side and "T" is on the long side.
In the triangle on the left, "M" is at the right angle. "N" is on the short side and "O" is on the long side.
Thus, the pairs of congruent angles are:
M ≅ R
O ≅ T
N ≅ S
When you write the statement of congruence between triangles, order the letters by their congruent pair.
MON ≅ RTS
