Find the the angle by subtracting 159 from 180 that’s your answer= 21 degrees
Answer:
Let length of the pool be L.
Deep
A —————————————><———————————----———————————— H
.................(18.5m)
H ——————————————————————————-———><————————- A
..............................................................................................................(10.5)
In same time, Andy covers 18.5 and Hardy covers L - 18.5.
In same time, Andy covers L - 18.5 + 10.5 while Hardy covers 18.5 + L - 10.5
The ratio of these distances covered would be the same since the speeds of both people are constant.
18.5/(L - 18.5) = (L - 8)/(L + 8)
Plug in the options to find that L = 45 works.
Answer:
no
Step-by-step explanation:
3.6 + 3.6 is not 9 & 2.84 + 2.84 is not 7.1
Calculate the square root which is -7*6-(-2)*(-3) and then multiply the numbers which is -42+2*(-3) that equals -42-6 and your answer is -48
245.34 is 174% of 141 :)
(1.74*141=245.34)
It helps to remember that "of" in math means to multiply. That's helped me for years.
