Rick works two jobs to pay for college. he tutors for $20 per hour and also works as a bag boy for $7 per hour. due to his class and study schedule, rick is only able to work up to 25 hours per week but must earn at least $200 per week. if t represents the number of hours rick tutors and b represents the number of hours he works as a bag boy, which system of inequalities represents this scenario? t + b less than or equal to 25 20t + 7b greater than or equal to 200 t + b greater than or equal to 25 20t + 7b = 200 t + b less than or equal to 25 20t + 7b less than or equal to 200 none of the systems shown represent this scenario.

Answers

Answer 1

the answer is actually in the question, but you have to write it out mathematically.

he needs at least $200 per week:

20t + 7b > 200 (greater than or equal to)

he can work up to 25 hours per week:

t + b < 25

so this is your system of inequalities. hope this helps!

A presidential candidate plans to begin her campaign by visiting the capitals in 44 of 5050 states. what is the probability that she selects the route of fourfour specific capitals? is it practical to list all of the different possible routes in order to select the one that is best?

Answers

Part A:

Given that A presidential candidate plans to begin her campaign by visiting the capitals in 4 of 50 states.

The number of ways of selecting the route of 4 specific capitals is given by

[tex] ^{50}P_4= \frac{50!}{(50-4)!} = \frac{50!}{46!} =50\times49\times48\times47=5,527,200[/tex]

Therefore, the probability that she selects the route of four specific capitals is [tex] \frac{1}{5,527,200} [/tex]

Part B:

The number of ways of selecting the route of 4 specific capitals is 5,527,200.

Since the number of ways of selecting the route of 4 specific capitals is too large it is not practical to list all of the different possible routes in order to select the one that is best.

Therefore, "No, it is not practical to list all of the different possible routes because the number of possible permutations is very large."

Final answer:

The probability of the presidential candidate selecting a specific route of four capitals is approximately 0.00575. It is not practical to list all the different possible routes to select the best one.

Explanation:

To find the probability that the presidential candidate selects a specific route of four capitals, we need to calculate the number of possible routes and divide it by the total number of routes. Since there are 44 capitals and we need to select 4, we can use the combination formula.

The number of possible routes is given by C(44,4) which is equal to 44!/(4!(44-4)!) = 44!/(4!40!) = (44*43*42*41)/(4*3*2*1) = 91,390.

The total number of routes is 50P44, which is equal to 50!/6! = (50*49*48*47...*7*6!)/(6!) = (50*49*48*47...*7) = 15,890,700.

Therefore, the probability of selecting the specific route of four capitals is 91,390/15,890,700 = 0.00575 (rounded to 5 decimal places). This means that there is a very low probability of selecting this specific route.

It is not practical to list all of the different possible routes in order to select the best one, as there are over 15 million routes. Instead, the candidate may use other criteria such as population density, political demographics, or strategic considerations to determine the best route.

Some airlines have restrictions on the size of items of luggage that passengers are allowed to take with them. suppose that one has a rule that the sum of the length, width and height of any piece of luggage must be less than or equal to 204204 cm. a passenger wants to take a box of the maximum allowable volume. if the length and width are to be equal, what should the dimensions of the box be?

Answers

Length, width, and height are all 68 cm. I am assuming that there's a formatting issue with this question and that the actual size limit is 204 cm. With that in mind, let's create a function giving the width of the box in terms of its height. So w = (204 - h)/2 Now let's create an expression giving the volume of the box in terms of height. v = lwh Since the width and length are the same, replace l with w v = wwh And now replace w with (102-h/2) v = (102-h/2)(102-h/2)h And expand the equation. v = (102-h/2)(102-h/2)h v = (10404 -51h - 51h + 0.25h^2)h v = (10404 -102h + 0.25h^2)h v = 10404h -102h^2 + 0.25h^3 Since we're looking for a maximum, that can only happen when the slope of the above equation is equal to 0. The first derivative will tell you the slope of the function at each point. So let's calculate the first derivative. For each term, multiply the coefficient by the exponent and then subtract 1 from the exponent. So: v = 10404h - 102h^2 + 0.25h^3 v = 10404h^1 - 102h^2 + 0.25h^3 v' = 1*10404h^(1-1) - 2*102h^(2-1) +3*0.25h^(3-1) v' = 10404h^0 - 204h^1 + 0.75h^2 v' = 10404 - 204h^1 + 0.75h^2 We now have a quadratic equation with A=0.75, B=-204, and C=10404. Use the quadratic formula to find the roots, which are 68 and 204. These 2 zeros represent a local minimum and a local maximum. The value 204 is obviously the local minimum since the box would have a width and length of 0 resulting in a volume of 0. So the height must be 68 which means the length and width are (204 - 68)/2 = 136/2 = 68. To prove that 68 is the optimal height, let's use a height of (68+e) and see what that does to the volume of the box. v = (102-h/2)(102-h/2)h v = (102-(68+e)/2)(102-(68+e)/2)(68+e) v = (102-(34+e/2))(102-(34+e/2))(68+e) v = (68-e/2)(68-e/2)(68+e) v = (4624 - 34e - 34 e + 0.25e^2)(68+e) v = (4624 - 68e + 0.25e^2)(68+e) v = 314432 - 4624e + 17e^2 + 4624e - 68e^2 + 0.25 e^3 v = 314432 - 51e^2 + 0.25e^3 Now look at the 2 terms that use e. The -51e^2 term will always be negative, but the +0.25e^3 term will be negative if e is negative and positive if e is positive. So a positive e value (e.g. Make the height larger) does have a possibility of increasing the volume if it can overcome the -51e^2 term. So let's make that equation 0 < -51e^2 + 0.25e^3 51e^2 < 0.25e^3 51 < 0.25e 204 < e So if we make the height 68 + 204 = 272, then we could have a box with a larger volume. But that's impossible since the largest measurement for any edge is 204 and that's assuming you're willing to set the length of the other 2 dimensions to 0.

18 girls out of 32 students is what percent?

Answers

18 girls represent 56.25 percent of the total number of students.

To find what percent 18 girls out of 32 students represent, you can set up a proportion comparing the number of girls to the total number of students. This proportion is represented by the fraction 18/32. To convert this fraction into a percentage, multiply it by 100.

Here's the calculation step by step:

Divide 18 by 32 to get the decimal form.

Multiply the result by 100 to get the percentage.

Performing the calculation gives:
(18/32) x 100 = 56.25%

Therefore, 18 girls represent 56.25 percent of the total number of students.

Suppose that you only have liability and comprehensive car insurance and you allow your roommate (who doesn't have car insurance) to drive your car to run an errand. What will likely happen if there is a single-car accident causing moderate damage to your car while your roommate is driving?

Answers

Generally, anyone living in your house is typically covered when driving your car, unless expressly excluded on the policy.

Permisive use also also allows you to allow your friends or family members who don’t live with you to use your car.

Permissive use means that if you give another driver permission to take your car, they will be covered by your car’s insurance coverage.

So if you allow your roommate (who doesn't have car insurance) to drive your car to run an errand.

What will likely happen if there is a single-car accident causing moderate damage to your car while your roommate is driving is that the insurance of your car will cover such accident.

what statement describes the function f(x)=|x^4-x^3|

Answers

did u ever get the answer for this

The given function f(x) = |[tex]x^{4}[/tex] - x³| is Option A. neither even nor odd because substituting -x changes the form of the function inside the absolute value. Thus, the function does not meet the criteria for either even or odd functions.

To determine if the function f(x) = |[tex]x^{4}[/tex] - x³| is even, odd, or neither, we need to check how it behaves under the transformation x -> -x.

An even function satisfies the property f(-x) = f(x) for all x, while an odd function satisfies f(-x) = -f(x) for all x.

First, let's consider the inside of the absolute value:

If we replace x with -x, we get: f(-x) = |[tex]-x^{4}[/tex] - (-x)³| = |[tex]x^{4}[/tex] + x³|.

We see that the expression has changed, since |[tex]x^{4}[/tex] - x³| is different from |[tex]x^{4}[/tex] + x³| . Therefore, f(x) does not exhibit the properties of being either even or odd.

This means the correct answer is:

Option A. The function is neither even nor odd.

Complete question:

Which statement describes the function f(x) = the absolute value of x^4 - x^3?

A. The function is neither even nor odd.

B. The function is both even and odd.

Answers

The answer is A. This can be seen in the table where y can be both 4 and 3 for when x = 3. In a function, an output can have more than one input, but an input can have have only one output.

Answer: A function is so F(X) = Y where for every X exist only one Y, in this case you can see that F(3) = 4 and F(3) = 3, so the independent variable x = 3, has two solutions y.

So the solution is A, because a function cannot have two different y values for one x value.

If jimmy as three balls and gives away one and if earl gives jimmy fifteen balls and jimmy loses seven. how many balls does he have?

Answers

I believe the answer is 10,
3-1=2+15=17-7=10

Answer: Jimmy has 10 balls .

Step-by-step explanation:

Since we have given that

Number of balls Jimmy has = 3

Number of lost balls = 1

Remaining balls Jimmy has = 3-1=2

Number of balls Earl gives to Jimmy = 15

Now,

Total Number of balls Jimmy has = 15+2=17

Again,

Number of balls Jimmy lost = 7

So,

Remaining balls Jimmy has = 17-7=10

So, he has 10 balls at last .

Why do astronomers say that the sun rotates once every 27 to 31 days, rather than give an exact number?

Answers

Astronomers cannot give an exact answer about how long it takes the sun to rotate because of the sun's matter. The sun is made up of gas and plasma, these types of matter have different weight than the solids that most planets are made out of. Different parts on the sun move at different speeds giving a range of days for the sun's rotation.

Astronomers provide a range for the Sun's rotation period due to differential rotation, with varying speeds at different latitudes.

This question demands basic understanding of planetaty motion i.e rotation and revolution in general and about motion of sun in particular

Astronomers say that the Sun rotates once every 27 to 31 days because of the phenomenon known as differential rotation. This means that the speed of rotation of the Sun varies based on its latitude.

The rotation period of the Sun is about 25 days at the equator, 28 days at latitude 40°, and 36 days at latitude 80°. Due to this variable rotation speed, astronomers provide a range rather than an exact number for the Sun's rotation period.

The length of a rectangle is 5 yd longer than its width. if the perimeter of the rectangle is 46 yd , find its area.

Answers

The area of the rectangle is 126 square yards.

Solving the area and perimeter of a rectangle.

The area of a rectangle is the multiplication of the length and the width. The perimeter of the rectangle is calculated by using the formula perimeter = 2(length × width).

Let the Length be (L) and the width be (w).

Length = w + 5Width = w

Perimeter = 2 (length + width)

Perimeter = 2 ((w+5) +w)

Perimeter = 2w + 10 + 2w

Perimeter = 4w + 10

Since Perimeter = 46 yd, then:

46 = 4w + 10

4w = 36

w = 36/4

w = 9 yards

Length = 9 + 5 = 14 yards

The area of the rectangle is:

Area = length × width

Area = 14 yd × 9 yd

Area = 126 yd²
