The distance from the base of the ladder to the way will be given by:
tan θ= opposite/adjacent
θ=70
adjacent=x
opposite=25 ft
thus
tan 70=25/x
thus
x=25/tan 70
hence:
x=9.1 ft
Answer: 9.1 ft
Answer:
a) draw a square with 8 on each side. put 2 gates of 1.3 on it somewhere
b) 29.4 m
c) $208.74
Step-by-step explanation:
8×4 =32
gates 2.6
Answer:
5 inches
Step-by-step explanation:
A square is all equal sides, so 20 inches divided by 4 is 5 inches.
Hope this helps :)
13a.) If you're dividing and the base (in this case the base is 10) is the same, subtract the exponents.
13b.) If you're multiplying and the base is the same, then you add the exponents:
13c.) This is similar to 13b:
The new mixture has a total volume of 5 L + 9 L = 14 L.
70% of the 5 L alcohol solution is alcohol, so that it contributed 3.5 L of alcohol to the mixture. The pure water contributed no alcohol. So in the mixture, the concentration of alcohol is
3.5 L / 14 L = 0.25, or 25%
