Since you're adding on to the regular price, you can say it is 125% of the price. Or you can use the regular equation:
Since you're only finding 25% of 24.5, you have to add on 24.5 because you're paying for the beach towel and applying the sales tax.
Now, since cents are to the hundredths place, you have to round.
The final price would be $30.63
Let w = liters of water needed
4.70= acid in 40% solution
4.70/70+w = .28
28=.28.(70+w)
70+w=100
w=30
30 liters of water is needed

Step-by-step explanation:
There are three possible correct answers in this problem.
You only need one of them, but I will give you all three, and you choose the one you prefer.
Answer 1.
Ray LG is an angle bisector.
m<KLH = 120°
m<KLG + m<GLH = m<KLH
60° + m<GLH = 120°
m<GLH = 60°
Since m<KLG + m<GLH = m<KLH, and m<GLH = m<KLG, then
ray LG is the angle bisector of <KLH.
Answer: ray LG
Answer 2.
Angles KLH and HLM are a linear pair and supplementary. Their measures add to 180°. Since m<KLH = 120°, then m<HLM = 60°.
m<HLI = 30°, so m<ILM = 30°.
That makes ray LI a bisector of angle HLM.
Answer: ray LI
Answer 3.
Since ray LI bisects <HLM, and m<HLM = 60, then m<ILM = 30°.
We are given m<JLM = 15°, so m<ILJ is also 15°. That makes ray LJ an angle bisector.
Answer: ray LJ
Answer:
Trey = 9 text messages
Rachel = 19 text messages
Juan = 57 text messages
Step-by-step explanation:
Let
Number of messages Trey sent = x
Number of messages Rachel sent = x + 10
Number of messages Juan sent = 3(x + 10)
Total messages = 85
Total = Trey + Rachel + Juan
85 = x + (x + 10) + 3(x + 10)
85 = x + x + 10 + 3x + 30
85 = 5x + 40
85 - 40 = 5x
45 = 5x
x = 45/5
x = 9
Number of messages Trey sent = x = 9 text messages
Number of messages Rachel sent = x + 10
= 9 + 10
= 19 text messages
Number of messages Juan sent = 3(x + 10)
= 3(9 + 10)
= 3(19)
= 57 text messages
