The surface area of this figure is __<u>310</u>__ square centimetres.
So the problem has no symbols, but we're going to multiply because the fraction on the left is right next to the parentheses.
-5/2 * 1/10x = -5x/20
I put "x" next to the 5 because the "x" counts as part of the numerator. Now that it's 5x over 20 that equals one, I'd first reduce -5x/20 into -x/4, then do
-x/4 * -4 = 1 * -4
To make the "x" side equal one, we have to multiply both sides by -4, to make both sides equal.
x = -4.
The rate at which his pulse is increasing after 3 minutes is 9.5 beats per minute
<h3>How to determine the beat rate after 3 minutes?</h3>
The given graph shows the curve and the tangent.
From tangent line, we have the following points:
(x,y) = (3,119) and (1,100)
The beat rate (m) at this point is:

So, we have:

Evaluate the differences

Evaluate the quotient
m = 9.5
Hence, the rate at which Sam's pulse is increasing after 3 minutes is 9.5 beats per minute

Hello!
The answer is: 15 mL
Why?
From the statement we have that 250 mg need to be given every 8 hours, we can calculate how many mg will be given each day (24 hours):

So,
a day
We also know that there are 50 mg cefaclor every 1mL,
So, to know how many mL will be given with 750mg, we just need to divide it by 50

Therefore,
15mL or 750 mg of cefaclor will be given each day.
Have a nice day!
First you woyld find how many hours total he worked.

Then take the number of hours and multiply by the pay earned per hour.

They would make $360 per week.
