Step-by-step explanation:

The radius of the hemisphere is 45 cm

Explanation:

Given:

Volume of the hemisphere, V = 60750π cm³

Radius of the hemisphere, r = ?

We know:

Volume of hemisphere = [tex]\frac{2\pi r^3 }{3}[/tex]

[tex]60750\pi = \frac{2\pi r^3 }{3} \\\\r^3 = 91125\\\\r = 45[/tex]

Therefore, the radius of the hemisphere is 45 cm

The radius of the hemisphere is 45 cm

The volume of a hemisphere is given by the formula

[tex]V = \frac{2}{3} \pi r^{3}[/tex]

Where V is the volume

and r is the radius

From the question,

V = 60750π cm³

Putting this into the formula,

We get

[tex]60750\pi = \frac{2}{3}\pi r^{3}[/tex]

∴ [tex]r^{3}= \frac{60750\pi \times 3}{2\pi}[/tex]

[tex]r^{3}= 91125[/tex]

∴ [tex]r =\sqrt[3]{91125}[/tex]

r = 45 cm

Hence, the radius of the hemisphere is 45 cm

Answer: The volume is 128pi cm or 402.12 cm. To increase the volume you can double the height, double the radius, double the radius but half the height, and make the radius and height both 6 cm.

Step-by-step explanation:

To find the volume of the cylinder, use the equation [tex]\pi r^2h[/tex]. After plugging everything in, the equation is [tex]\pi (4^2)*8[/tex]. [tex]4^2[/tex]=16. 16*8=128. If you need a more accurate answer, multiply by pi to get 402.12 cm.

Doubling the height creates a volume of 256pi cm.

Doubling the radius creates a volume of 512pi cm.

Doubling the radius and halving the height creates a volume of 256pi cm.

Making both the radius and height 6 cm creates a volume of 216pi cm.

The external angles of a 12-gon add up to 360 degrees so each is 30 degrees.  That makes the internal angle the supplement, PQR=150 degrees.

We have an isosceles triangle so the other two angles add to 30 degrees, so 15 degrees.

Answer: 15 degrees

Angle PRO in a regular 12-gon is half an interior angle, so it measures [tex]$\boxed{75^\circ}$[/tex].

The strategy is to first calculate the sum of the interior angles of the dodecagon, and then divide that number by 2 because any angle of a regular polygon can be found by subtracting [tex]$180^\circ$[/tex] from the quotient you get when you divide the sum of the interior angles by the number of angles.

Answer:

Step-by-step explanation:

Ms. Roa's monthly internet payment, being constant, would be represented by a horizontal line on a graph with time (months) on the X-axis and cost on the Y-axis. The consistency of the payment amount regardless of time represents a constant rate, demonstrated graphically.

The subject of your question involves mathematics, specifically, the concept of the relationship between constant costs and time, which can be demonstrated using linear graphs. In Ms. Roa's case, she pays the same amount each month for internet service. This means that the cost per month is constant, so if you make a graph showing time on the X axis (in months) and cost on the Y axis, you would see a straight horizontal line, indicating that the cost does not change over time.

For example, if Ms. Roa pays $50 each month, then every point on the line will be at Y = 50 (for cost), regardless of the X value (time). The concept of a constant rate is important in understanding the relationship between different quantities, and is commonly used in Displaying Data Graphically and Interpreting the Graph.

Answer: 7

Step-by-step explanation:

4x7= 28 and 2x7=14

14+28= 42

The inequality representing the possible number of party hats (x) Kimani ordered from Party Plus is x>20. This means Kimani ordered more than 20 party hats to spend over $40, given the assumed minimum cost per hat from Party Plus.

Let's denote the number of party hats Kimani ordered from Party Plus as x. Now, if each party hat costs a certain amount, and Kimani spent over $40, we can set up an inequality to represent this situation.

Let be the cost of each party hat. The total cost (T) is given by multiplying the number of hats (x) by the cost per hat (c). Therefore, T=xc.

The problem states that Kimani spent over $40, so we can express this as an inequality: T>40

Now, substitute the expression for T in terms of x and xc>40

Since we are specifically looking at the scenario where Kimani ordered the hats from Party Plus, let's assume that each hat costs at least $2 (as a hypothetical example). So, c≥2. Now, substitute

c≥2 into the inequality:

x⋅2>40

Simplify the inequality:

2x>40

Now, divide both sides by 2 to solve for x>20.

Answer:

[tex]a_{n}[/tex] = 6n - 5

Step-by-step explanation:

There is a common difference d between the consecutive terms, that is

d =7 - 1 =  13 - 7 = 19 - 13 = 25 - 19 = 6

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 1 and d = 6, thus

[tex]a_{n}[/tex] = 1 + 6(n - 1) = 1 + 6n - 6 = 6n - 5

Answer:

Step-by-step explanation:

t1 = 1 = 6 * 1 - 5

t2 =7 = 6 * 2 - 5

t3 = 13 = 6 * 3 - 5

t4 = 19 = 6*4 - 5

t5 = 25 = 6*5 - 5

Answer:

95%

Step-by-step explanation:

In this case we can apply a formula that tells us that:  

# (AUB) = #A + #B - #AnB  

Where A would be the ones who enjoy swimming and B would be the ones who enjoy running. AnB is the intersection of both sets, that is, those who enjoy doing both things, these values we have, if we replace them we have left:

#(AUB) = 80% + 70% - 55%

#(AUB) = 95%

Which means that 95% of people enjoy either swimming or running

The percentage of people who enjoy swimming and/or running is calculated to be 95%.

We have 80% of people who enjoy swimming, and 70% who enjoy running, with a 55% overlap of people who enjoy both.

The formula for the principle of inclusion-exclusion is:

Union = A + B - Intersection

Therefore, the percentage of people who enjoy swimming and/or running is:

Union = 80% + 70% - 55% = 95%

Hence, 95% of people enjoy at least one of the two activities.

Answer:

Step-by-step explanation:

There are 9 numbers on the dice. (One number for each side.)

Total Number of events: 9

There are 2 numbers that are greater than seven.  (8 and 9)

Preferred number of events: 2

[tex]\frac{preferred}{total} =\frac{2}{9}[/tex]

[tex]\frac{2}{9}[/tex]  is already at it's lowest terms.

The probability should be 2/9.

The probability of rolling a number greater than 7 on a 9-sided die is 2/9 or approximately 22.2%.

In the language of probability, an event is any outcome or combination of outcomes. The probability of any event is normally calculated by dividing the number of ways that the event can occur by the total number of outcomes. In this problem, a die with 9 sides is rolled once, giving a total of 9 possible outcomes (the numbers 1 to 9). The event in question is rolling a number greater than 7, which consists of two outcomes: 8 and 9. So, the probability of this event is

Number of ways the event can occur / Total number of outcomes = 2 / 9 = 0.222 (to three decimal places), or approximately 22.2%.

To find:

Volume of the rectangular prism.

Solution:

Surface area formula:

[tex]SA = 2(lw+wh+lh)[/tex]

Substitute the given values.

[tex]4362 = 2(36\times21 +21 \times c+36 \times c)[/tex]

[tex]4362 = 2(756+21 c+36 c)[/tex]

[tex]4362 = 2(756+57c)[/tex]

[tex]4362 = 1512+114c[/tex]

Subtract 1512 from both sides.

[tex]4362- 1512 = 1512+114c - 1512[/tex]

[tex]2850=114c[/tex]

Answer:

y = -(5/2)x - 1

Step-by-step explanation:

slope intercept form is y = mx + b

m is the slope

b is the y intercept

The y intercept is shown to be (0,-1), so b = -1

The equation is now y = mx -1

slope= rise/run

The rise is (4-(-1))=5

The run is (-2-0)=-2

5/-2 is the slope (m)

The equation is y = -(5/2)x - 1

Answer:

y = -5/2 x-1

Step-by-step explanation:

First we need to find the slope

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

   = (-1 -4)/(0--2)

   = (-5)/+2

   = -5/2

We know the y intercept is -1 since that is where it crosses the y axis

We will use the slope intercept form of the equation

y= mx+b  where m is the slope and b is the y intercept

y = -5/2 x-1

Find the middle.

It is between 14 and 24

Take the average.

Average here = median = (14 + 24)/2 = 38/2 = 19

Final answer:

The median of the data set (79, 27, 24, 11, 14, 11) is found by first arranging the numbers in ascending order, and then taking the average of the two middle numbers, which yields a median of 19.

Explanation:

The median is the middle value of an ordered data set. To find the median, we first need to arrange the numbers in ascending order. The set of numbers given are 79, 27, 24, 11, 14, 11. Arranged in order they are 11, 11, 14, 24, 27, 79.

Since there are 6 values (an even number), we take the average of the two middle numbers. In this case, the two middle numbers are 14 and 24. Hence, we calculate the median as follows:

(14 + 24) / 2 = 38 / 2 = 19.

Therefore, the median of this data set is 19.
