Work Shown:

r = 6 = radius

V = volume of a sphere of radius r

V = (4/3)*pi*r^3

V = (4/3)*pi*6^3

V = 904.77868423386

V = 904.8

I used my calculator's stored version of pi (instead of something like pi = 3.14)

The units "cubic meters" can be abbreviated to m^3 or \(m^3\)

The volume of the given sphere is 904.8 cubic meters. Thus, option B is the answer.

         The volume of a sphere can be calculated using the formula:

V = \(4/3 * \pi * r^3\),

Where V is the volume and r is the radius of the sphere.

\(\pi\) = 3.14

The radius of the sphere (r) = 6m

Plugging in the given radius of 6m into the formula, we get:

V = (4/3) * \(\pi\) * (6^3)

V = 1.333 * \(\pi\) * 216

V = 1.333 * 3.14 * 216

V = 4.1866 * 216

V = 904.8 cubic meters

Therefore, when the radius of the sphere is 6m, the volume of the sphere is 904.8  cubic meters.

We have a transformation for the triangle EFG. In this case is a translation.

We can verify with one of the points which one of the graphs correspond to this transformation.

The transformation is:

(x,y) --> (x-3, y + 1)

We look at point E = (-0.5, 0).

We apply the transformation and get:

(-0.5, 0) --> (-0.5-3, 0+1) = (-3.5, 1)

Then, the graph that has E located in the point (-3.5, 1) is the right one.

The correct formula to simulate a variable uniformly distributed between 100 and 200 using x is c. 100 + 100x.

To simulate a variable uniformly distributed between 100 and 200 using a random number x between 0 and 1, you can use the formula:

Variable = 100 + (200 - 100) * x

Let's break down the formula:

a. 100 + x: This will give a variable that ranges from 100 to 101, not between 100 and 200.

b. 200 - x: This will give a variable that ranges from 199 to 200, not between 100 and 200.

c. 100 + 100x: This formula is correct and will give a variable that ranges from 100 to 200, with x ranging from 0 to 1.

d. 200x: This formula will give a variable that ranges from 0 to 200, not between 100 and 200.

Therefore, the correct formula to simulate a variable uniformly distributed between 100 and 200 using x is c. 100 + 100x.

Answer:

No

Step-by-step explanation:

substitute the x- coordinate of the point into each equation and if both have the value of the y- coordinate of the point then it is a solution.

y = 5(3) + 9 = 15 + 9 = 24 ≠ 9

y = 3 + 6 = 9

since the point does not satisfy both equations then it is not a solution of the system.

No

Step-by-step explanation:

y=5x+9

y=x+6

\(y = 5x + 9 \: \: - - - - - - (1) \\ y = x + 6 \: \: - - - - - - -(2) \\ from \: equation \: (2) \\ y - 6 = x \\ x = 6 + y - - - - - - (3)\\ y = 5x + 9 \\ y = 5(6 + y) + 9 \\ y = 30 + 5y + 9 \\ 5y - y = 30 + 9 \\ 4y = 39 \\ y = - \frac{39}{4} \\ y = 9.75 \\ \\ y = 9.75 \: into \: (2) \\y = x + 6 \\ 9.75 = x + 6 \\ 9.75 - 6 = x \\ x = 9.75 - 6 \\ x = 3.75\)

So the answer is NO

The limit of the given function as x approaches infinity is infinity.

To find the limit of the given function as x approaches infinity, we need to analyze the behavior of the function for very large values of x.

First, we can observe that the term 49x^2 dominates the other terms in the function as x gets very large. This is because the square of any number grows much faster than a linear function (x) or a constant function (-7x).

Therefore, we can simplify the given function as follows:

lim x→[infinity] (49x^2 + x − 7x) = lim x→[infinity] 49x^2

Now we can directly evaluate the limit by applying the rule that states if a function is of the form ax^n where a and n are constants and x approachesinfinity, then the limit is infinity if n > 0 and negative infinity if n < 0.

In this case, a = 49 and n = 2, which is greater than 0. Therefore, the limit as x approaches infinity is infinity.

Answer:

  (a)  135

  (b) 28%

Step-by-step explanation:

We can write equations relating pears to oranges, solve them, and then find the number of apples. Let p, o, and 'a' represent the numbers of pears, apples, and oranges.

  p/o = 5/3 . . . . . the ratio of pears to oranges is 5:3

  p -o = 54 . . . . . there are 54 more pears than oranges

  a -o = 3 . . . . . .  there are 3 more apples than oranges

__

Multiply the first equation by 3/5o to get ...

  3/5p = o

Substitute that into the second equation:

  p -(3/5)p = 54

  2/5p = 54 . . . . . . simplify

  p = 54(5/2) = 135 . . . . multiply by 5/2 to get the number of pears

There are 135 pears in the basket.

__

  a = 3 +o = 3 +3/5p = 3 +3/5(135) = 3 +81 . . . . solve for the number of apples

  a = 84

The percentage of fruits that are apples is ...

  apples/total = 84/(135 +81 +84) = 84/300 = 28/100 = 28%

Answer:

8.3\(cm^{3}\)

Step-by-step explanation:

Answer:

First, we need to know how to calculate the area and the permiter of a rectangle.

To calculate the area, we multiply base by height and to calculate the perimeter, we sum all sides.

Knowing this, we can say that the area is 3x * (x+5) and the perimiter is 3x + 3x + x + 5 + x + 5, as we know both are the same, we write it as an equation:

\(3x * (x+5) = 3x + 3x + x + 5 + x + 5\)

Now we solve the equation:

\(3x^2 +15x = 6x + 2x + 10\)

\(3x^2+15x =8x + 10\)

\(3x^2+15x-8x-10=0\)

\(3x^2+7x-10=0\\\\x_1=\frac{-10}{3}\\x_2 = 1\)

As the negative result doesn't have sense, we only pick the second one: 1.

If x = 1, then area would be 3*6 = 18 square inches and perimeter 3+3+6+6 = 18 inches

Answer:

\(\huge\boxed{x = 1 \ \ \ \ OR \ \ \ \ x = -\frac{10}{3} }\)

Step-by-step explanation:

Length = 3x

Width = x + 5

Area of Rectangle:

=> (Length)(Width)

=> (3x)(x+5)

=> \(3x^2 + 15x\)

Perimeter of Rectangle:

=> 2 (Length) + 2 (Width)

=> 2(3x) + 2(x+5)

=> 6x + 2x + 10

=> 8x + 10

Given Condition is:

Perimeter = Area

\(3x^2 + 15x\) = 8x + 10

\(3x^2 + 15 x -8x - 10 = 0\\3x^2 + 7x -10 = 0\\3x^2 + 10 x - 3x -10 = 0\\x(3x+10) - 1(3x+10) = 0\\(x-1) (3x+10) = 0\)

Either,

x - 1 = 0       OR     3x + 10 = 0

x = 1             OR       3x = -10

x = 1             OR        x = -10 / 3

To obtain 2.7 moles of Selenium (Se) for a reaction at STP (Standard Temperature and Pressure), you would need to measure a volume of 60.48 L.

To determine the volume of selenium required, we can use the ideal gas law equation, which states that PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature.

At STP, the pressure is 1 atm, and the temperature is 273.15 K.

Rearranging the ideal gas law equation to solve for volume (V), we have V = nRT/P.

Substituting the given values:

n = 2.7 moles

R = 0.0821 L·atm/(mol·K)

T = 273.15 K

P = 1 atm

V = (2.7 moles * 0.0821 L·atm/(mol·K) * 273.15 K) / 1 atm

V ≈ 60.48 L

Therefore, to obtain 2.7 moles of Selenium (Se) for the reaction at STP, you would need to measure a volume of approximately 60.48 L.

Answer:

y= -x-1

Step-by-step explanation:

(x1,y1) = (-1,0) ; (x2,y2) = (0,-1)

y=mx+b

m=\(\frac{y2-y1}{x2-x1}\)=\(\frac{-1-0}{0-(-1)}\)=\(\frac{-1-0}{0+1}\)=\(\frac{-1}{1}\)=-1

Then substitute either x1y1 or x2y2 (it's gonna give the same answer anyways) and m to find b.

y=mx+b

0=(-1)(-1)+b

0=1+b

0-1=1-1+b

b=-1

Then substitute b and m to get the equation.

y=(-1)x+(-1)

y= -x-1

The height of the monument is 570 feet. Since the shadow of the monument and the shadow of the tourist are cast at the same time, their angles of elevation are the same.

To solve this problem, we need to use the concept of similar triangles. We can set up a proportion: (height of Monument) / (length of Monument's shadow) = (height of tourist) / (length of tourist's shadow)

Let x be the height of the Monument. Then we have:

x / 285 = 5 / 2.5

Cross-multiplying, we get:

2.5x = 5 * 285

Simplifying, we get:

x = 570

Therefore, the Monument is 570 feet tall.

To find the height of the monument, we can use the concept of similar triangles. Since the shadow of the monument and the shadow of the tourist are cast at the same time, their angles of elevation are the same.

Set up a proportion using the height and shadow length of the tourist and the monument:

(height of monument) / (shadow of monument) = (height of tourist) / (shadow of tourist)

Let x represent the height of the monument. Then:

x / 285 = 5 / 2.5

Now, solve for x:

x = (5 / 2.5) * 285
x = 2 * 285
x = 570 feet

The height of the monument is 570 feet.

1. The probability that Layla gets more than 3 heads is 0.40 (rounded to the nearest hundredth).

P(X>3) = 0.40.Let X represent the number of heads Layla gets on flipping a coin that has a 60% chance of showing heads. She is going to flip the coin five times and we are supposed to find the probability that she gets more than 3 heads. The probability that Layla gets more than 3 heads is P(X>3).

Solution :We are given that the coin has a 60% chance of showing heads each time it is flipped. The probability of getting a head (success) is p = 0.6 and the probability of getting a tail (failure) is q = 0.4. As Layla is going to flip the coin five times, we have n = 5.On each flip, X can either be a head or a tail. Thus, X is a binomial random variable with parameters n = 5 and p = 0.6.P(X>3) can be calculated as:P(X > 3) = P(X = 4) + P(X = 5)P(X = 4) = nCx × p^x × q^(n-x) = 5C4 × 0.6^4 × 0.4^1 = 0.2592P(X = 5) = nCx × p^x × q^(n-x) = 5C5 × 0.6^5 × 0.4^0 = 0.07776P(X > 3) = P(X = 4) + P(X = 5) = 0.2592 + 0.07776 = 0.33696 ≈ 0.40

2. Probability of surgery being effective on 12 patients = 0.00000078643 and the probability that surgery is effective on at least 12 patients out of 20 is 0.1985502502.

Let p be the probability that a surgical intervention results in an increased quality of life in a patient, which is given as 60%. Let X be the number of patients out of 20 who have an increased quality of life after undergoing the surgery. We are supposed to find the probability that surgery is effective on 12 patients out of 20.

Solution :Let X be the number of patients out of 20 who have an increased quality of life after undergoing the surgery. Then X is a binomial random variable with parameters n = 20 and p = 0.6.The probability of surgery being effective on exactly 12 patients can be calculated as:P(X = 12) = nCx × p^x × q^(n-x) = 20C12 × 0.6^12 × 0.4^8 = 0.00000078643 (rounded to 11 decimal places)

The probability of surgery being effective on at least 12 patients can be calculated as:P(X ≥ 12) = P(X = 12) + P(X = 13) + ... + P(X = 20)Using a binomial probability distribution table, we can calculate this probability as:P(X ≥ 12) = 0.00000078643 + 0.0000105188 + 0.0000976064 + 0.0007052774 + 0.0038752048 + 0.0163110784 + 0.052553726 + 0.125428942 = 0.1985502502Therefore, the probability that surgery is effective on 12 patients out of 20 is 0.00000078643

This is the required final answer  Emily spends $300y/x  and Andy spends $432y/x for wire.

The answer provided below has been developed in a clear step-by-step manner.

1 foot =12 inches

1 yard=36 inches

Emily needs (25×12)=300 inches wire

and Andy needs (12×36)=432inches wire

As the cost for x inches wire is $y

cost for a 1-inch wire is $x/y

So, the cost for 300 inches of wire is $300y/x

cost for 432 inches of wire is $432y/x

so, Emily spends $300y/x

and Andy spends $432y/x for wire.
