Can someone please help me

Answer:

So you must do tan(27)=x/2000
Then once you have x you do: x^2+y^2=c^2
solve for c
then add up all the sides and then subtract your total by 2000 to get the difference

The order is for 250 mg of Ampicillin IVPB qan. The IVPB comes prepared from the pharmacy in a 50 mL IV bag with instructions

o-na [289]

The volume flow rate is in engineering and physics, especially fluid fluidity, the volume of fluid that is passed per unit time, usually even though depicted by symbol Q. It's the fluid that flows in that time. SI units have $\bold{\frac{ m^3}{s}}$ cubic meters, and the calculation can be defined as follows:

Solution:

The bag of IVPB is 50 mL and it can be infused for 15 minutes.
It implies the IVPB bag of 50 ml must be injected within 15 minutes
Or a bag of 50 ml injected at 15/60 hours

$\to \bold{flow\ rate= \frac{volume \ (ml) }{time\ ( hr)}}$

$\bold{= \frac{50}{(\frac{15}{60})} }\\\\ \bold{=\frac{50}{0.25}} \\\\ =\bold{200\ \frac{ml}{hr}}\\\\$

Thus answer is 200 ml/ hr

Alex saved x dollars.

steposvetlana [31]

Answer:
Ethan = 1.(3x)

Step-by-step explanation:
Let's split "Ethan saved 1/3 more than that"
That = x
So, Ethan saved 1/3 more than x
Meaning that Ethan = x + 1/3x
Combine like terms
Ethan = 1 1/3x
which equals to
Ethan = 1.(3x)

Hope this helps :)
Have a great day

Suppose that E and F are two events and that P(E)=0.2 and P(F|E)=0.5 What is P(E and F)?

Tresset [83]

By definition of conditional probability,

P(F | E ) = P(F and E ) / P(E )

Then

P(F and E ) = P(F | E ) P(E ) = 0.5 • 0.2 = 0.1
