Answer:

z = 10

Step-by-step explanation:

First apply multiplication to inside the parenthesis:

2(z+5) = 2z + 10

5(z+ 2) = 5z + 10

10(z − 1) = 10z - 10 now write the full equation

2z + 10 + 5z + 10 = 10z - 10 add like terms

7z + 20 = 10z - 10 transfer like terms to the same side of the equation

20 + 10 = 10z - 7z

30 = 3z divide both sides by 3

10 = z

Answer:

A = 18 and B = -15

Explanation:

The second term (20(S + J)) denotes the total number of field goals they both scored in the final 20 minutes.

An expression is a grouping of figures, symbols, and algebra (such as addition, reduction, multiply, and division) that expresses a value. Variables, that are symbols for unknowable values, are symbols that can be included in expressions. The statement can be evaluated to give a specific value after the contents of the variables are assigned. An expression using a variable x, for instance, is 3x + 5. When we give x a number of 2, the expression is evaluated to: 3(2) + 5 = 6 + 5 = 11 . As a result, the expression's value at x = 2 is 11.

given

a. Assume that "S" represents the number of field goals Suzy scores each minute and "J" represents the number of field goals Joshua scores each minute.

The calculation for the total number of field goals Suzy and Joshua score in their 30-minute workout is as follows:

\(Field goals total = (9 + 10 S) + (20 (S + J)\)

The first term (9 + 10S) denotes Suzy's total number of field goals in the first 10 minutes, while the second term (20(S + J)) denotes the total number of field goals they both scored in the final 20 minutes.

Answer:

individual pay (a) = cost of popcorn / number of friends

Step-by-step explanation:

Assuming the cost of the popcorn is to be split evenly among the three friends, where all three friends are to split 5.70, the pay per friend is;

individual pay (a) = 5.70 (cost of popcorn) / 3 (number of friends)

Part A: To find the total surface area of the rectangular prism, we need to calculate the areas of all six faces and then add them together.

Given dimensions:

Length = 7 feet

Width = 3 feet

Height = 4.8 feet

Surface Area of each face:

Front and back faces: Length * Height

= 7 feet * 4.8 feet

= 33.6 square feet

Top and bottom faces: Width * Length

= 3 feet * 7 feet

= 21 square feet

Side faces: Width * Height

= 3 feet * 4.8 feet

= 14.4 square feet

Total Surface Area:

2 * (Front and back faces) + 2 * (Top and bottom faces) + 2 * (Side faces)

= 2 * 33.6 square feet + 2 * 21 square feet + 2 * 14.4 square feet

= 67.2 square feet + 42 square feet + 28.8 square feet

= 137 square feet

Therefore, the total surface area of the bench is 137 square feet.

Part B: To calculate the cost of covering the bench with ceramic tiles, we need to multiply the total surface area by the cost per square foot.

Cost per square foot = $0.89

Total Surface Area = 137 square feet

Total cost to cover the bench:

= Cost per square foot * Total Surface Area

= $0.89 * 137 square feet

= $121.93

Therefore, it will cost $121.93 to cover the bench with ceramic tiles.

The function f(x) = x² - 1/x + 1, with domain [0, ∞), does not have an absolute maximum on its domain, but this does not contradict the extreme value theorem.

The extreme value theorem states that if a real-valued function f is continuous on a closed interval [a, b], then f must have both an absolute maximum and an absolute minimum on that interval.

However, the theorem does not apply to functions that have an open interval as their domain, such as f(x) = x² - 1/x + 1 with a domain of [0, ∞).

In this case, f(x) approaches infinity as x approaches 0, but it does not have a maximum value within the given domain. The lack of an absolute maximum for f(x) on [0, ∞) is consistent with the behavior of the function, and it does not violate the extreme value theorem since the domain is not a closed interval.

Therefore, the function f(x) = x² - 1/x + 1, defined on [0, ∞), lacks an absolute maximum, but this does not violate the extreme value theorem.

Isaac has a 1/40 chance of winning the raffle, or a 2.5% chance. This indicates that he has a 2.5% probability of having his ticket chosen out of the 40 tickets that were sold. This is because there is only one raffle winner and it is impossible to predict which ticket will be picked.

It's also crucial to remember that his odds of winning are entirely independent of those of any other ticket holder; nobody else's ticket will affect the outcome of the raffle. As a result, Isaac has the same chance of winning as any other ticket holder. It's also vital to remember that regardless of how many tickets are sold, the likelihood of winning stays the same.

Step-by-step explanation:

The probability of  4 in the tens place is \(\frac{1}{9}\), the probability of  at least one 4 in the tens place or the units place is \(\frac{1}{5}\), the probability no 4 in either place is \(\frac{4}{5}\).

(a) total number of 2-digit terms =(99 - 10) + 1 = 90

n(s) = 90

A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%

number of 2 digits that have 4 in tens place = 40, 41, 42 ......49

n(a) = 10

P(A) =\(\frac{ n(a)}{n(s)}\)

Substituting the values

P(A) = \(\frac{10}{90}\)

P(A) = \(\frac{1}{9}\)

Therefore, P(A) = \(\frac{1}{9}\)

(b) From the previous one, we know the P(A) = \(\frac{1}{9}\)

Number of 4's in units place = 14, 24, 34.....94 = 9

n(b) = 9

P(B) = \(\frac{ n(b)}{n(s)}\)

Substituting the values

P(B) = \(\frac{9}{90}\)

P(B) =\(\frac{1}{10}\)

P(A and B) = \(\frac{1}{10}\)

Using OR probability, we have

P(A or B) = P(A) + P(B) - P(A and B)

P(\(\frac{1}{9}\) or \(\frac{1}{10}\)) = \(\frac{1}{9}\) + \(\frac{1}{10}\) - \(\frac{1}{90}\)

P(\(\frac{1}{9}\)or \(\frac{1}{10}\)) = \(\frac{1}{5}\)

Therefore, P(\(\frac{1}{9}\)or \(\frac{1}{10}\)) = \(\frac{1}{5}\)

(c) Probability of no 4 in either place = 1 - ( probability of 4 in either place)

= 1 - \(\frac{1}{5}\) = \(\frac{4}{5}\)

Therefore, probability of no 4 in either place = \(\frac{4}{5}\)

Therefore, the probability that the integer chosen has a 4 in the tens place is \(\frac{1}{9}\), P(\(\frac{1}{9}\) or \(\frac{1}{10}\)) = \(\frac{1}{5}\), and probability of no 4 in either place = \(\frac{4}{5}\).

Math, thats how it works.

The circulation of F around C is -16. No, F is not equal to V f for some function f. The flux of F across C is -8. No, F is not equal to V x G for any vector field G.

(a) The circulation of F around C is -16.

Using Green's Theorem, we can write the circulation of F as the line integral around the boundary of D:

∮CF · dr = ∬D (∂Q/∂x - ∂P/∂y) dA

where P = 9x + 5y, Q = 2x - 7y, and dr = dx i + dy j.

Taking the partial derivatives, we get:

∂Q/∂x - ∂P/∂y = 2 - 9 = -7.

Thus, the circulation of F around C is:

∮CF · dr = ∬D -7 dA = -7(area of D) = -16.

(b) No, F is not equal to V f for some function f.

If F were equal to the gradient of some scalar function f, then the circulation of F around any closed path would be zero. However, we just calculated that the circulation of F around C is -16, which means F cannot be expressed as the gradient of any scalar function.

(c) The flux of F across C is -8.

Using Green's Theorem, we can write the flux of F across C as the line integral around the boundary of D:

∮CF · ds = ∬D (∂P/∂x + ∂Q/∂y) dA

Taking the partial derivatives, we get:

∂P/∂x + ∂Q/∂y = 9 - 7 = 2.

Thus, the flux of F across C is:

∮CF · ds = ∬D 2 dA = 2(area of D) = -8.

(d) No, F is not equal to V x G for any vector field G.

If F were equal to the curl of some vector field G, then the flux of F across any closed surface would be zero. However, we just calculated that the flux of F across C is -8, which means F cannot be expressed as the curl of any vector field.

Answer:

the answer is (a) 28.

Step-by-step explanation:

The given situation can be represented by a linear equation of the form:

Cost = mx + b

where "m" is the slope (the rate of change of cost with respect to time), "x" is the number of hours of the tour, and "b" is the y-intercept (the cost when x = 0).

In this case, the y-intercept is $60, which represents the one-time fee. The cost increases by $28 per hour, so the slope is:

m = $28/hour

Therefore, the answer is (a) 28.

Answer:

A = 1600π cm²

Step-by-step explanation:

We are given that a circle's radius increases 4 cm every second.

We want to know how large the area of the circle is after 10 seconds.

We first need to find how large the radius will be.

We know the proportion of the rate increase / time; for every 1 second, the rate increases by 4 cm.

We can write this as a proportion:

\(\frac{4 cm}{1 s} = \frac{x}{10s}\)

We can cross multiply to get:

4 cm * 10 s = x * 1 s

Divide both sides by 1 s

(4 cm * 10 s) / (1 s) = 40cm = x

So, after 10 seconds, the radius will be 40cm.

We aren't done yet though, remember that the question wants us to find the area of the circle.

The area can be calculated using the equation A = πr², where r is the radius.

We can substitute 40 as r in the equation to get:

A = πr² = π * (40)² = 1600π cm²

If positive integer x has 3 prime factors and 8 total factors, then (n+1)^3 total factors will x^n have where n is a positive integer

      In the question given that positive integer x has 3 prime factors and 8 total factors

      To find How many total factors will x^n have where n is a positive integer

The formula used the total number of factors of a positive integer

            x = (a+1) (b+1) (c+1)…  where a, b, c are prime factors of x.

Substituting the values from the given information:

          x = p*q*r (where p, q, and r are prime numbers)

     Total number of factors of  x = (1+1) (1+1) (1+1)

      A total number of factors of  x = 2 * 2 * 2

     The total number of factors of x = 8

If x has 3 prime factors, then the other factor could be 1x = p*q*rx^1

                                                                                               = p*q*r(1+1) (1+1) (1+1)

                                                                                               = 8

      factors  x^2 = p^2*q^2*r^2(2+1) (2+1) (2+1) = 27

      factors  x^3 = p^3*q^3*r^3(3+1) (3+1) (3+1) = 64

      factors x^n = p^n*q^n*r^n(n+1) (n+1) (n+1)

     Number of factors = (n+1)^3

              Hence the number of factors in x^n is (n+1)^3.
