m-4n+3.5+4/5pm-4n3.54/5, Can you make the question more readable, or can you actually put fractions is the question? I WILL REVISE MY ANSWER
Step-by-step explanation:
currently the constant is 3.5
Angle R is the reference angle as its the only given angle (other than the 90 degree angle).
Opposite angle R is segment PQ
PR is the hypotenuse
Use the sine rule to find that...
sin(angle) = opposite/hypotenuse
sin(R) = PQ/PR
sin(19) = PQ/11
11*sin(19) = PQ
PQ = 11*sin(19)
PQ = 3.58124969902872 <<-- use a calculator (degree mode)
PQ = 3.58
Answer: 3.58
Answer:

Step-by-step explanation:
The tick marks you see on the sides denote congruence. If they have the same number of tick marks, then their side length are congruent.
And, recall that congruent side lengths have the same measure.
So, look at the sides with 2 tick marks. They are congruent. Therefore:

Subtract x from both sides:

Subtract 5 from both sides:

So, x is 7.
Now, look at the sides with only 1 tick mark. Again, they are congruent. Thus:

We already know x is 7. So:

Add:

Add 4 to both sides:

So, y is 16.
4 cups make 1 quart.
If she wants to give at least 2 cups to 12 guests, she needs 2 * 12 = 24 cups.
24 cups is 24 / 4 = 6 quarts.
Then, you conclude that 7 quarts is enough.
Answer: Yes, she has enough lemonade for each guest
