Have you done any work on these problems yet?  It's unrealistic (and not helpful to you in the long run) to expect someone else to do them for you and to give you the answers.  Still, I will address Problem #16:

Convert    40 yards
                -------------
                   4 sec

to the equivalent speed in miles per hour.  You'll need two of the following three identities:  3 feet = 1 yard; 5280 feet=1 mile; 3600 sec = 1 hour.

Why not reduce this fraction first?  (40 yards) over (4 sec) reduces to 10 yards/sec.

Now convert yards to miles, using 5280 feet = 1 mile and 3 feet = 1 yard.  I see you already have reduced that 40/4 to 10.  Your result should be

10 yards/sec.

Know what to do next?   See my previous paragraph.  Please share your work.

Step-by-step explanation:

$75      30%      0.70(75) = x      $52.50

$18       65%      0.35(18) = x      $6.30

$60      30%     0.70x = 42        $42

$35       20%     0.80x = 28       $28

$150      25%     0.75(150) = x     $112.50

A child weighing 22.5 kg has an IV order for Vancomycin Calculate the q8h per dose dosage if the label states that
vodka [1.7K]

Answer:

q8h dosage = 112.5mg

Step-by-step explanation:

Given

Child Weight = 22.5 kg

Daily Intravenous Dosage = 40mg/kg

Type of Dose = q8h

Required

Calculate the q8h per dose

We start by calculating the total daily dosage in mg

This is calculated by multiplying the child weight by the intravenous dosage

Daily Dosage = 22.5kg * 40mg/kg

Daily Dosage = 900mg

This implies that the body weight requires 900 mg daily

Next is to calculate the q8h dosage

q8h means every 8 hours.

q8h dosage = 900mg/8

q8h dosage = 112.5mg

How would I do this one?
viva [34]
First we would need to make a diagram, and from the given it would seem like it is a right triangle with the height as 760 ft. We have an angle given 89°18' which would need to be converted to degrees form, which is 89.3<span>°. 

Now we would need to look for the ground distance, meaning the adjacent of the triangle. Since we have been given the angle and the height (which is the opposite side from the angle) we use the trigonometric function cotangent.

</span><span>760 Cot <span>[<span><span>(<span>89.3</span>)</span>∘</span>]</span>= 9.29 ft, that is the answer.</span>
