You want log √(9/25).  Recognizing that √9 = 3 and that √25 = 5, we get

log 3/5, which by rules of logs comes out to log 3 - log 5.

To four decimal places:

log 3 - log 5 = 0.4771 - 0.6990, or -0.2218.

Solve the equation for x in terms of c.
Vanyuwa [196]

Answer:

D

Step-by-step explanation:

Simplify and rearrange to solve.

2/3 (cx + 1/2) - 1/4 = 5/2

2/3 (cx + 1/2) = 5/2 + 1/4

2/3 (cx + 1/2) = 11/4

cx + 1/2 = 11/4 divided by 2/3

cx + 1/2 = 33/8

cx = 33/8 - 1/2 = 29/8

x= 29 / 8 divided by x = 29/8c.

Hope this helps.

Aight so I know the answer is 105° but idk how someone got that answer. Could you help?
Anit [1.1K]

Firstly we need to find m<DNY

m<DNY=(60+90)÷2=75

N9w we can find m<KNY

m<KNY+m<DNY=180°(Because these are adjacent corners)

m<KNY+75°=180°

m<KNY=180°-75°

m<KNY=105°
