A patient's order is 70 milligrams of a drug. Available in stock is 80 milligrams in 1 milliliter of liquid. How many milliliters should be administered?
The required milliliters should be administered is 0.875 milliliter .
What is Volume?Volume is a measure of occupied three-dimensional space. It is often quantified numerically using SI derived units or by various imperial units. The definition of length is interrelated with volume.
Given:
A patient's order is 70 milligrams of a drug.
Available in stock is 80 milligrams in 1 milliliter of liquid.
According to given question we have
80 milligrams = 1 milliliter
70 milligrams =1*70/80 milliliter
70 milligrams = 0.875 milliliter
Therefore, the required milliliters should be administered is 0.875 milliliter .

Write a slope-intercept equation for a line passing through the point (4,7) that is parallel to y=x+1. Then write a
second equation for a line passing through the given point that is perpendicular to the given line.
Answer:
y = x + 3
y = -x + 11
Step-by-step explanation:
When the slopes are parallel they are the same. When slopes are negative, the slope is the negative reciprocal.
Parallel: The slope is 1. This is the coefficient of the x in the equation given. If you do not see a number before the x like in y = x + 1, then number is 1.
Use this form:
y =mx + b Us the slope of 1 to put in for m. Use 4 for x and 7 for y
7 =(1)4 + b Solve for b.
7 = 4 + b Subtract 4 from both sides.
3 = b
The equation for the parallel line is
y = x + 3.
Perpendicular:
y = mx + b This time the slope is -1 Still use 4 for x and 7 for y
7 = (-1)4 + b
7 =-4 + b add 4 to both sides
11 = b
The equation would be y = -x + 11

Explain how you would estimate the value of 57−−√ by determining the two consecutive whole numbers that it lies between. Write the two numbers and explain the process you used to select them.
The two consecutive whole numbers that it lies between are 28 and 29.
What are the consecutive numbers?The consecutive numbers are those number which follow each other continuously in the order from smallest to largest numbers.
Let the two consecutive numbers be x and x + 1
x + x + 1 = 57
Combine like terms;
2x + 1 = 57
Now Subtract 1 from both sides;
2x = 57- 1
2x = 56
Divide both sides by 2
x = 56/2
x = 28
Thus, x + 1 = 28 + 1 = 29
The two consecutive whole numbers that it lies between are 28 and 29.

If tan a = x + 1 and tan ß = x - 1, then verify that: 2cot(a - B) = x²
[tex]
\cot(a-b)=\frac{\frac{1}{(x+1)(x-1)}+1}{\frac{1}{x-1}+\frac{1}{x+1}} \\ \\ =\frac{1-1+x^2}{2} \\ \\ =\frac{x^2}{2} \\ \\ \therefore 2\cot(A-B)=x^2[/tex]
Answer:
See below for proof.

Answer the question.
The distance from the Earth to the Sun is about 1.5 x 108 km, while the distance from the Earth to the
moon is about 3.8 x 105 km. If a scale model of the solar system is constructed so that the distance
from the Earth to the Sun is 100 meters, what will be the distance from the Earth to the moon?
Select one:
O a. 39, 474 m
O b.
39.5 m
O c. 6.36 m
O d. 0.25 m
The distance from the Earth to the moon, in the scale model, is d. 0.25 m
As per the known fact, ratio of measurement in real is equal to the ratio of measurement on scale. Further, ratio will be calculated in this case as -
Distance from Earth to Sun in real : Distance from Earth to Moon in real = Distance from Earth to Sun on scale : Distance from Earth to Moon on scale
Keep the values in mentioned relation to find the distance from Earth to Moon.
1.5×10⁸:3.8×10⁵ = 100:distance from Earth to Moon on scale
Distance from Earth to Moon on scale = 100×3.8×10⁵/1.5×10⁸
Distance from Earth to Moon on scale = 0.25 m
Therefore, the correct option for distance is d. 0.25 m.

When you subtract two numbers, if you reduce the first number in the subtraction by one, the result is one less. This is true.
How to calculate the value?It should be noted that in subtraction when you reduce the first number, you will get a value that's lesser by 1.
In this case, if we have 20 - 5 = 15, then 19 - 5 = 14. We can see that 14 and 15 is a difference of 1.

if log4^u - log8^v =1 find u in terms of v
u in terms of v will be represented with the logarithm function as v = u log (- 4 ) - ( log 8) ⁻¹
We are given that:
log 4 ^ u - log 8 ^ v = 1
This can also be written in another way using the logarithm properties. We get that:
u log 4 - v log 8 = 1
Subtract v log 8 from both the sides:
u log 4 = 1 + v log 8
v log 8 = u log 4 - 1
v = ( u log 4 - 1 ) / log 8
v = u log (- 4 ) - ( log 8) ⁻¹
Therefore, we get that, u in terms of v will be represented with the logarithm function as v = u log (- 4 ) - ( log 8) ⁻¹
