The circumference of the vase is 18.84 inches.

Step-by-step explanation:

The circumference of the cylinder is same as the circumference of its base.

Moreover, the base of the cylinder is actually a circle.

So we need to find the circumference of the circle to find the circumference of the cylinder.

From the given figure, we know that the diameter of the base d= 6 inches.

∴The formula for the circumference of the circle = 2πr or dπ.

⇒ circumference = 6×3.14.

                             = 18.84.

So the circumference of the circle is 18.84 inches.

∴The circumference of the cylindrical vase is also 18.84 inches.

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.

Final answer:

Using substitution, we solve the equation 6x + 6y = 0 for y, yielding y = -x. Substituting into -7x + 2y = 18 and solving for x gives x = -2. Substituting x back into y = -x, we find y = 2.

Explanation:

To solve the system of equations using substitution, we can isolate one variable in one equation and then substitute it into the other equation. In this case, we've been given the system:

-7x + 2y = 18

6x + 6y = 0

From the second equation, we can isolate y:

6x + 6y = 0

x + y = 0

y = -x

Now, substitute y = -x into the first equation:

-7x + 2(-x) = 18

-7x - 2x = 18

-9x = 18

x = -2

Now that we have the value for x, we can substitute it back into y = -x to find y:

y = -(-2)

y = 2

The solution to the system is x = -2 and y = 2.

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 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°.

The transformation

[tex](x,y) \rightarrow (x-5,-y+1)[/tex]

maps triangle XYZ onto triangle X”Y”Z”.

Step-by-step explanation:

Let us take point Z on the XYZ triangle and see what sequence of transformations we have to apply to map it into the point Z''.

Now Z = (-2, 2) and Z'' = (-7, -1).

The x-coordinate goes from -2 ⇒ -7.

The y-coordinate goes from 2 ⇒  -1.

The x-coordinate is just shifted by -5; thus, [tex]x \rightarrow x-5[/tex], and the y-coordinate first transforms as [tex]y \rightarrow -y[/tex], and is then shifted by 1; thus, it transforms as [tex]y \rightarrow -y+1[/tex].

So we have the full transformation

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 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

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.

After setting aside 4 hours for sports, Burt has 6 hours left for television. Since each movie is 2 hours, Burt can watch 3 two-hour movies in the remaining time.

Burt's parents allow him a total of 10 hours of television per week. Since he is planning to watch four hours of sports, we subtract this amount from the total to find the time remaining for watching movies. Here's how we solve for the number of movies Burt can watch:

Total TV time allowed: 10 hours per week

Time planned for watching sports: 4 hours

Time remaining for movies: 10 hours - 4 hours = 6 hours

Since each movie is two hours long, we then divide the remaining time by the length of one movie:

6 hours divided by 2 hours/movie = 3 movies

Therefore, Burt is planning to watch three two-hour movies this week.
