Convert 19/20 to a percent.

We need to get a denominator to 100 and this is easy because 100 is divisible by 20. 100/20 = 5. So, multiply both sides by 5 to get 95/100. So, as a decimal, it is 0.95 and as a percent (multiply by 100) is 95%. Hope this helped!

As a nurse, part of your daily duties is to mix medications in the proper proportions for your patients. For one of your regular

spayn [35]

Answer:

10 milligrams of Medication A

Step-by-step explanation:

We'll write proportions/ratios for this:

20:16 is the usual proportion, and x:8 is this week's dose. The ratio from A to B has to be equal, so

20/16 = x/8

Cross-multiply:

(20)(8) = (16)(x)

160 = 16x

divide both sides by 16

x = 10

Point B ∈ AC. Find the length of segments AB and BC if AC = 20 cm and: AB:BC = 3:7

madam [21]

Answer:

Length of AB = 6 cm

Length of the segment BC = 14 cm

Step-by-step explanation:

Here, B is a point on a segment AC.

AB : BC = 3:7

Length of the segment AC = 20 cm

Now, let the common ratio between the segment is x.

So, the length of AB = 3 x , and Length of BC = 7 x

Now, AB + BC = AC

⇒ 3x + 7x = 20

or, 10 x = 20

or, x = 2

Hence, the length of AB = 3 x = 3 x 2 = 6 cm

and the length of the segment BC = 7x = 7 x 2 = 14 cm

Referring to triangle ABC, find the area of the triangle.

kondaur [170]

Answer:

$Area = 337$

Step-by-step explanation:

Given

$a = 42.5$

$c = 35.5$

$B = 153.5^\circ$

Required

Area of triangle

This is calculated as:

$Area = 0.5 *a* c * \sin(B)$

This gives:

$Area = 0.5 *42.5* 35.5 * \sin(153.5)$

$Area = 0.5 *42.5* 35.5 * 0.4462$

$Area = 336.602125$

$Area = 337$ --- approximated
