Answer: 11.14
Step-by-step explanation: This is right bro. 1000%
You are given Richard’s piano practice for 3 piano solos. Every piano sol
he makes takes 5/12 hour. You are asked to find how long Richard is going to
practice his piano solo. So we have for every 1 piano solo he makes this is
equal to 5/12 hours. This can be best represented by ratio and proportion.
1 piano solo/(5/12 hour) = 3 piano solo/(number of hours)
Number of hours = 3 piano solo/ (1 piano solo/5/12 hours)
<u>Number of hours = 5/4 hours or 1.25 hours.</u>
Answer:
(B) 
Step-by-step explanation:
we can use formula

where
Po is the initial population
r is the growth rate
t is the time in months
We are given
initial population of insects
so, Po=6
The scientists find that the insect population, x, is growing exponentially 20% per month
so, r=0.20
now, we can plug these values

there to be a population of 477 insects
so, P(t)=477
now, we plug it
and we get

Answer:
Step-by-step explanation:
3/x = sin45
x = 3/sin45
x = 3 / ½(√2)
x = 3(2/√2)
x = 3((2√2)/2)
x = 3√2
