Answer:

B. 200 doses

Step-by-step explanation:

Given,

1 dose is required for 100 mg,

Since, 1 mg = 0.001 g,

⇒ 100 mg = 0.1 g

⇒ 1 dost is required for 0.1 g,

Thus, the ratio of doses and quantity ( in gram ) is $\frac{1}{0.1}=10$

Let x be the doses required for 20 grams,

So, the ratio of doses and quantity is $\frac{x}{20}$

$\implies \frac{x}{20}=10$

$\implies x=200$

Hence, 200 doses can be obtained from 20 grams of the drug.

Option 'B' is correct.

According to the Census Bureau, in 2014 California had an estimated population of 3.88 x 10^7 and Wyoming had an population of 5

Verdich [7]

The population of California is 3.88 x 10^7 - 5.84 x 10^5 = 3.82 x 10^7 more than the population of Wyoming. Alternatively the population of California is 3.88 x 10^7 / 5.84 x 10^5 = 66 times the population of Wyoming.

A sphere has a radius of 16 in. Which statements about the sphere are true? Check all that apply.

Wewaii [24]

Answer:

The sphere has a diameter of 32 in. CORRECT: the diameter of a sphere doubles its radio, so if the radio equals 16,the diameter measures the double, in this case, 32.
The radius' lenght is one half the length of the diameter. CORRECT: , by definition, the diameter is the maximum distance between two opposite points on the surface of the sphere, and its lenght equals twice the radius because the radius is the distance between the center of the sphere and any point of the frontier of the sphere (then, one colud imagine that the distance between two opposite points in a sphere can be united by two radius, or a diameter).
The volume (V) of a sphere can be calculated as $\frac{4\pi r^3}{3}$ , where r is the radio. In this case, the volume of the sphere will be $\frac{4\pi\times16^3}{3}=\frac{4\pi\times4096}{3}$ , which is also equal to $\frac{16384\times\pi}{3}$ .

The measure of ∠P is five less than four times the measure of ∠Q. If ∠P and ∠Q are supplementary angles, find m∠P

MArishka [77]

Answer:

P=143

Step-by-step explanation:

So, we know that P and Q are supplementary angles. In other words:

$\angle P +\angle Q =180$

We also know that P is 5 less than 4 times Q. Thus:

$\angle P=4\angle Q-5$

Substitute the second equation into the first:

$(4\angle Q-5)+\angle Q=180$

Find Q. Combine like terms:

$5\angle Q-5=180$

Add 5 to both sides:

$5\angle Q=185$

Divide both sides by 5:

$\angle Q=37$

So, Q is 37 degrees.

Q and P are supplementary, which means that P is 180-37 or 143 degrees.

And we're done!

Don't know how to do this<br><br> simplify each expression by combining terms

Ilya [14]

Answer:

Combining like terms is actually pretty straightforward, you just have to combine like terms. In the problem 5c+2c, it would equal 7c since c is a common variable in this equation.

In the next question 16p+5+p-3x+6-x, it would equal 17p-4x+11 because 16p+p is 17p, -3x-x is -4x, and 5+6 equals to 11.

In the third question 18p+3-8p-5 would equal to 10p-2 since 18p-8p equals to 10p, and 3-5 equals to -2.

In the last question 9u+11v-22u+12v, it would equal to -13u+23v because 9u-22u equals to -13, and 11v+12v is 23v.

I hope this helped you!

Alexeev081 [22]

Answer:

the answer is 1

Step-by-step explanation:

if you are splitting the recipe in half then just split the amount of the ingredients in half too

half of the 2 cups of flour would be 1 cup of flour

you would also get 9 muffins instead of 18 muffins
