Answer:

1936 π square units

Step-by-step explanation:

Given the information:

The circumference of a great circle of a sphere is 44π.

As we know the formula used to find a circle's circumference is:

C = 2πr , where r is the radius of the circle

In this situation, we know C = 44π

<=> 2πr  = 44π

<=> r = 22 units

Hence, the Surface Area of the sphere

S.A = 4π[tex]r^{2}[/tex]

= 4π[tex]22^{2}[/tex]

= 1936 π square units

Answer:

1.150411783 E130

Step-by-step explanation:

The probability of drawing two red marbles is approximately 16.7%.

To find the probability of drawing two red marbles from the bag, we need to find the probability of drawing one red marble and then, given that the first marble was red, drawing another red marble. The probability of drawing a red marble on the first draw is 4/9 (since there are 4 red marbles out of a total of 9 marbles). After the first marble is drawn, there are now 8 marbles left in the bag, including 3 red marbles.

Therefore, the probability of drawing a red marble on the second draw, given that the first marble was red, is 3/8. To find the probability of both events occurring, we multiply the probabilities: (4/9) × (3/8) = 1/6, or approximately 16.7%.

The probability of drawing 2 red marbles without replacement from a bag containing 4 red, 3 blue, and 2 green marbles is 16.7%.

The question is asking for the probability of drawing two red marbles from a bag that contains 4 red marbles, 3 blue marbles, and 2 green marbles, without replacing the first one drawn.

Firstly let's figure out the total number of ways to draw 2 marbles from a bag of 9 marbles. Using combination formula, the total number of possible ways is: 9C2 = 36.

Now, how many ways can you draw 2 red marbles from 4? That will be: 4C2 = 6 ways.

So the probability of drawing 2 red multiplies, without replacement, is therefore 6 / 36 = 0.167 or 16.7% when rounded to the nearest tenth of a percent.

Step-by-step explanation:

285/1000 The fraction is not reduced to lowest terms. We can reduce this fraction to lowest

terms by dividing both the numerator and denominator by 5.

Why divide by 5? 5 is the Greatest Common Divisor (GCD)

or Greatest Common Factor (GCF) of the numbers 285 and 1000.

So, this fraction reduced to lowest terms is

57/200

So your final answer is: 0.285 can be written as the fraction 57/200

−0.258 written as a fraction in its simplest form is [tex]-\frac{129}{500}[/tex]

To write a given decimal as a fraction in its simplest form,

We will first express the decimal as a fraction and then reduce it to its lowest form.

The given decimal is −0.258

−0.258 written in fraction is [tex]-\frac{258}{1000}[/tex]

Now, we will reduce [tex]-\frac{258}{1000}[/tex] to its lowest form

First, we will divide both the numerator and denominator by 2 (Since 2 is a common factor)

We get

[tex]-\frac{258}{1000} = -\frac{258 \div 2}{1000 \div 2} = -\frac{129}{500}[/tex]

Since the fraction cannot be reduced further, then −0.258 as a fraction in its simplest form is [tex]-\frac{129}{500}[/tex]

Hence, −0.258 written as a fraction in its simplest form is [tex]-\frac{129}{500}[/tex]

Final answer:

The number of bulls in a herd with a bull-to-cow ratio of 1:6 is one-seventh of the total number of animals in the herd, represented as x/7.

Explanation:

In the scenario where the ratio of the number of bulls to cows is 1:6, we can express the number of bulls in terms of x, where x represents the total number of animals in the herd.

Let's define the number of bulls as B and the number of cows as C. Given the ratio B:C = 1:6, for every 7 animals in the herd (1 bull + 6 cows), there is 1 bull.

To find the number of bulls in terms of x, we divide the total number of animals by the sum of the parts of the ratio (1+6=7). So, the formula to find the number of bulls (B) is:

B = x / 7

Therefore, if x is the total number of animals in the herd, the number of bulls is one-seventh of x.

226 feet

Step-by-step explanation:

The maximum height of the projectile is 226 feet

Given the equation of the height modelled as h(t) = –16t^2 + 48t + 190

The ball reaches the maximum height at the point where v = dh/dt = 0

dh/dt = -32t + 48
32t = 48
t = 1.5s

Get the maximum height;

h(1.5) = –16(1.5)^2 + 48(1.5) + 190

h(1.5) = -36 + 72 + 190
h(1.5) = 226 feet

Hence  the maximum height of the projectile is 226 feet

Answer:

You should get 42

Step-by-step explanation:

In the picture I sent you, to find quartile 1 and 3 and the median use the order you have and slash out from the left and the right, if you don't get 2 numbers that you have to add and divide by 2 for the median you have to make lines outside of the middle number and slash on each side to get quartile 1 and quartile 3. Quartile 2 is the median.

The third quartile of the data set is, 42.

The numbers arrange in order to least to greatest number is called Ascending order.

Now, For the third quartile of the data set, we first need to find the median, which is the second quartile.

Hence, We can ordering the data set in ascending order:

20, 21, 24, 25, 28, 29, 35, 37, 42, 43, 44

Here, The median is the middle number or the average of the two middle numbers if the data set has an even number of values.

In this case, we have 11 values, so the median is the 6th value, which is 29.

And, we need to find the third quartile, which is the median of the upper half of the data set. The upper half of the data set includes the values:

35, 37, 42, 43, 44

The median of these values is the third quartile.

Hence, take the middle value or the average of the two middle values if there is an even number of values in the upper half.

In this case, there are 5 values in the upper half,

Hence, the median is the 3rd value,

⇒ 42.

Therefore, the third quartile of the data set is, 42.

Answer:

C. x = 4√7

Step-by-step explanation:

This is a right triangle

The hypotenuse is 3+8  (the radius is 3 and the exterior length is 8)

We can use the Pythagorean theorem

a^2 +b^2 = c^2

3^2 + x^2 = 11^2

9+x^2 = 121

Subtract 9 from each side

9-9 + x^2 = 121-9

x^2 = 112

Take the square root of each side

sqrt(x^2) = sqrt(112)

x = sqrt(16*7)

x = 4 sqrt(7)

To find the surface area of a square pyramid, you need to calculate the lateral area and the area of the base. The lateral area can be found using the formula (1/2) × perimeter of the base × slant height. The base area is equal to the side length squared. To find the total surface area, you add the lateral area and the base area.

To find the surface area of a square pyramid, we need to calculate the lateral area and the area of the base.

Lateral Area

The lateral area of a square pyramid can be found using the formula:

Lateral Area = (1/2) × perimeter of the base × slant height

In this case, the slant height is given as 13mm and the base length is given as 11mm, so we have:

Lateral Area = (1/2) × 4 × 11mm × 13mm = 286mm2

Base Area

The base of the square pyramid is a square with side length 11mm. Therefore, the area of the base is:

Base Area = side length × side length = 11mm × 11mm = 121mm2

Total Surface Area

To find the total surface area, we add the lateral area and the base area:

Total Surface Area = Lateral Area + Base Area = 286mm2 + 121mm2 = 407mm2

Therefore, the surface area of the square pyramid is 407mm2.

Answer: x² + 4x - 32

Step-by-step explanation: So to multiply these two binomials together, let's use the F.O.I.L. method.

Remember, F.O.I.L. stands for First, Outter, Inner, Last.

This is because we start with the product of the first terms which is x², then we add the product of the outer terms which is 8x, then we add the middle terms which is -4x, and then we add the product of the last terms which is -32.

So we have x² + 8x + -4x + -32.

Combining the like terms 8x + -4x, our final answer is x² + 4x - 32.

Answer:

The area of the sector is 3pi/2

Step-by-step explanation:

A sector is that part of a circle bounded by 2 radii and an arc

The circle has an area of 9 pi with a central angle of 60 degrees.

Now the area of the sector is pretty much straight forward to calculate. Since it is a circle, the total angle we have is 360.

Now the sector subtends an angle of 60 degrees at the centre. What this means is that the sector is exactly 1/6 of the circle. meaning that cutting the circle into 6 slices will give the sector.

Thus, the area of the sector is one-sixth the area of the circle.

The area of the sector is thus 1/6 * 9pi = 9pi/6 = 3pi/2 or 3/2 pi
