Answer:
163/20 or 8.15
Step-by-step explanation:
well we are going to do PEMDAS
parentheses
exponents
multiplication/ division
addition/ subtraction
2 + 2/5 x 23/4 (i made the fractions into decimals)
2 + 6.15
163/20 or 8.15
I'd still double check with someone on this but I believe that the answer is ×=(-6/5m+3/5p) I'd still double check but I'd ur in a big hurry and just need it done then put that
Answer:
24761 mosquitoes
5.4 days
Step-by-step explanation:
Let the equation that shows the population of the mosquitoes after x days,

Where,
P = Initial population,
r = rate of increasing per day,
Here, A = 1000, when x = 0,

A = 1900 when x = 1,

Thus, the required function that represents the population after x days,

If x = 4,
The number of mosquito after 4 days,

If A = 60,000,


Taking log both sides,


Thus, there will 60,000 mosquitoes after 5 days.
Answer:
x=2
y=1.732
Step-by-step explanation:
we use the formulae.....
SOHCAHTOA
where..Cos 60°=1/x
cos60=0.5
0.5=1/1
<u>X</u><u>=</u><u>2</u>
0.8660=y/2
y= 1.732
