Answer:

24 cm

Step-by-step explanation:

Using the formula for a right cylinder: V = (pi)(r^2)(h) you can plug in the numbers provided

384(pi) = (pi) × (4^2) × h

<solve for h>

384(pi) = (pi) × (16) × h

<divide by 16pi>

24 = height

Answer:

24 = h

Step-by-step explanation:

V = πr²h

384π = π(4)²h

384π = 16πh

24 = h

Therefore the inspector can perform three tests in 35 different ways.

Step-by-step explanation:

i) It is given that there is a total of seven tests that the inspector can perform.

ii) it is also given that the inspector needs to select or choose three tests only out of the seven.

iii) therefore this is a Combination problem.

iv) therefore the number of combinations or selections possible is given by

The best approximation for the measure of angle ABC is 58.3° ⇒ 3rd answer

Step-by-step explanation:

Let us revise the trigonometry ratios in the right triangle ABC, where B is the right angle, AC is the hypotenuse, AB and BC are the legs of the triangle

The trigonometry ratios of the angle BAC, the opposite side to this angle is BC and the adjacent side to it is AB are

In Δ ABC

∵ ∠ BCA is a right angle

∴ The hypotenuse is AB

∵ The adjacent side to ∠ABC is BC

∵ AB = 20 centimeters

∵ BC = 10.5 centimeters

- Use cosine ratio to find the measure of the angle because you

   have the adjacent side of the angle ABC and the hypotenuse

∵ m∠ABC is x

∵ [tex]cos(x)=\frac{BC}{AB}[/tex]

∴ [tex]cos(x)=\frac{10.5}{20}[/tex]

- To find x use the inverse of cos(x)

∵ [tex]x=cos^{-1}(\frac{10.5}{20})[/tex]

∴ x = 58.33°

∴ m∠ABC = 58.33°

The best approximation for the measure of angle ABC is 58.3°

The best approximation for the measure of angle ABC is 31.7°.

To find the measure of angle ABC (x), we can use trigonometric ratios. Since angle BCA is a right angle, we can use the sine function, which relates the opposite side to the hypotenuse in a right-angled triangle.

Let's denote the sides of the triangle as follows:

BC is the opposite side to angle ABC, with a length of 10.5 cm.

AB is the hypotenuse, with a length of 20 cm.

AC is the adjacent side to angle ABC.

Using the sine function, we have:

[tex]\[ \sin(x) = \frac{\text{opposite side}}{\text{hypotenuse}} = \frac{BC}{AB} \][/tex]

[tex]\[ \sin(x) = \frac{10.5}{20} \][/tex]

[tex]\[ \sin(x) = 0.525 \][/tex]

Now, we need to find the angle whose sine is approximately 0.525. Using a calculator or trigonometric tables, we can approximate the angle x. The angle whose sine is approximately 0.525 is about 31.7°.

Answer:

24ml

Step-by-step explanation:

First, calculate the amount needed in mg for each day.

The rate given for each dose is 150mg every 6 hours. Since there are 24 hours in a day, divide the number of hours in a day by how often to give the medication to get the number of doses each day.

24 hours ÷ 6 hours = 4 doses daily

The total mg each day is the number of doses daily multiplied by the amount in each dose.

4 doses daily X 150 mg = 600mg daily

Calculate how many mg of medication are in 1 ml given by the pharmacy.

75mg ÷ 3ml = 25mg/ml

Divide the mg of medication daily by the concentration the pharmacy dispenses.

600 mg daily ÷ 25mg/ml = 24ml

You will administer 24ml daily.

Check by doing these steps backwards:

24ml per day gives 600 mg of medication because there are 25mg per 1 ml. 24ml X 25mg = 600mg

Each day you need to administer 150mg X (24h ÷ 6h) of medication.

150mg X 4 = 600mg, which is the correct amount.

Answer:

The equation of line M in slope intercept form is    [tex]y=\frac{3}{2}x+1[/tex]

The equation of line M in standard form is  [tex]3x-2y=-2[/tex]

Step-by-step explanation:

step 1

Find the slope of line M

The formula to calculate the slope between two points is equal to

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

we have the points

(2,4) and (0,1)

substitute

[tex]m=\frac{1-4}{0-2}[/tex]

[tex]m=\frac{-3}{-2}[/tex]

[tex]m=\frac{3}{2}[/tex]

step 2

Find the equation of the line M in point slope form

[tex]y-y1=m(x-x1)[/tex]

we have

[tex]m=\frac{3}{2}[/tex]

[tex]point\ (0,1)[/tex]

substitute

[tex]y-1=\frac{3}{2}(x-0)[/tex]

[tex]y-1=\frac{3}{2}x[/tex] ----> equation in point slope form

step 3

Find the equation of line M in slope intercept form

[tex]y=mx+b[/tex]

Isolate the variable y in the equation of the line in point slope form

[tex]y-1=\frac{3}{2}x[/tex]

Adds 1 both sides

[tex]y=\frac{3}{2}x+1[/tex]

step 4

Find the equation of the line M in standard form

[tex]Ax+By=C[/tex]

where

A is a positive integer

B and C are integers

we have

[tex]y=\frac{3}{2}x+1[/tex]

Multiply by 2 both sides

[tex]2y=3x+2[/tex]

[tex]3x-2y=-2[/tex] ---> equation in standard form

Final answer:

The equation of line m that contains the points (2, 4) and (0, 1) is found by calculating the slope which is 3/2, and using the y-intercept which is 1. The final equation of the line m is y = (3/2)x + 1.

Explanation:

To find the equation of line m in the xy-plane that contains the points (2, 4) and (0, 1), we first need to calculate the slope of the line. The slope m is calculated as the rise over the run. For our points, the slope can be found by the formula:

m = (y2 - y1) / (x2 - x1)

So,

m = (4 - 1) / (2 - 0) = 3 / 2.

Next, we use one of the points and the slope to find the y-intercept (b). Using the point (0, 1), we plug these values into the equation for a straight line y = mx + b:

1 = (3/2) × 0 + b

Therefore, b = 1.

The equation of line m is y = (3/2)x + 1.

The probability that Mark draws a yellow marble and then a green marble is 1/9.

To find the probability that Mark draws a yellow marble and then a green marble, we first need to find the total number of marbles in the bag. The bag contains 4 green marbles, 3 red marbles, and 2 yellow marbles, so the total number of marbles is 4 + 3 + 2 = 9.

Since Mark draws without replacement, the probability of drawing a yellow marble first is 2/9. After drawing a yellow marble, there are now 1 yellow marble and 8 total marbles left in the bag, so the probability of drawing a green marble second is 4/8, or 1/2.

To find the overall probability, we multiply the probabilities of the individual events. Therefore, the probability that Mark draws a yellow marble and then a green marble is (2/9) * (1/2) = 1/9.

Answer:

The value of b for the intersection of two lines at given points is 4

Step-by-step explanation:

Given as :

The two line equations are

y = 2 x + 7                ..........A

And

y = 2.5 x + b            ............B

Since, The two lines are intersecting at point  [tex]x , y[/tex] = - 6 , - 5

Now Solving equation A and B we get

2 x + 7 = 2.5 x + b

Or, 7 - b = 2.5 x - 2 x

Or, 7 - b = . 5 x

∵ intersecting points are x , y = - 6 , - 5

putting the value of y from points

i.e 7 - b = . 5 × ( - 6 )

Or, 7 - b = 3

Or, b = 7 - 3

∴  b = 4

So, The value of b = 4

Hence, The value of b for the intersection of two lines at given points is 4 Answer

The required value of x that satisfies the equation x/4 = -7 is x = -28.

To solve for x when x divided by 4 equals -7, we can follow these steps:

Start with the equation: x/4 = -7.

To isolate x, we want to get rid of the division by 4. We can do this by multiplying both sides of the equation by 4:

(4)(x/4) = (4)(-7).

The 4 on the left side cancels out with the 4 in the denominator, leaving us with:

x = -28.

Therefore, the value of x that satisfies the equation x/4 = -7 is x = -28.

Final answer:

The value of x in the equation x divided by 4 equals -7 is -28. To find x, we multiply both sides of the equation by 4, resulting in x=-28. Substituting back into the original equation confirms the solution is correct.

Explanation:

To solve the equation x divided by 4 equals -7, we want to find the value of x. We can do this by performing the inverse operation of division, which is multiplication. So if x divided by 4 is -7, we can multiply both sides of the equation by 4 to solve for x:

x / 4 = -7
4 * (x / 4) = 4 * (-7)
x = -28

So, the value of x is -28. As a check, you can substitute -28 back into the original equation:

-28 / 4 = -7

Which simplifies to:

-7 = -7

This confirms that the solution is correct since it results in an identity, showing that the left side of the equation is equal to the right side.
