Answer: Option A and Option B.
Step-by-step explanation:
You need to remember the logarithms properties:
![log(a)+log(b)=log(ab)\\\\log(a)-log(b)=log(\frac{a}{b})\\\\log(a)^b=b*log(a)](https://tex.z-dn.net/?f=log%28a%29%2Blog%28b%29%3Dlog%28ab%29%5C%5C%5C%5Clog%28a%29-log%28b%29%3Dlog%28%5Cfrac%7Ba%7D%7Bb%7D%29%5C%5C%5C%5Clog%28a%29%5Eb%3Db%2Alog%28a%29)

Answer:
~89.84m
Step-by-step explanation:
tan61 = r/24
r = 24tan61 ≈ 89.84
Step-by-step explanation:
step 1: add the ratios
1/2 + 1/4 + 1/5 = 0.95
step 2: divide each ratio by the total sum of the ratios and multiply by a 100
(1/2 ÷ 0.95) × 100 = 52.63 rounded off equals to 53
(1/4 ÷ 0.95) × 100 = 26.31 rounded off equals to 26
(1/5 ÷ 0.95) × 100 = 21.05 rounded off equals to 21
These ratios should add up to a 100
so the ratio are 53 : 26 : 21
Lets first figure out what each of the words mean in symbols.
Three less: - 3
a number: x (you can use any variable, but the question says to use x)
five times a number: 5x
is 12: = 12
Now we need to put the equation together.
5x - 3 = 12 is the sequence that Danny wrote.
