Answer:

x = 2 pizzas

Step-by-step explanation:

Let

x = number of pizza ordered

Stella’s Pizza charges $16.00 room rental fee and an additional $8.00 for each pizza ordered.

cost for a party at Stella’s Pizza = 16 + 8x

Napoli’s Pizza charges $24 for the room rental fee and an additional $6.00 for each pizza ordered.

cost for a party at Napoli’s Pizza = 24 + 6x

Equate the cost for a party at Stella’s Pizza and cost for a party at Napoli’s Pizza

16 + 8x = 24 + 6x

8x - 6x = 24 - 16

2x = 8

x = 8/4

= 2

x = 2

Surface area of the tent not including the floor = 2,336 ft²

Volume of the triangular prism tent = 6,720  ft³

The tent has a shape of a triangular prism. Therefore:

Surface area of the tent not including the floor = PL + bh - (a × c) where,

P = perimeter of the triangular face of the tent = 14 + 25 + 25 = 64 ft

L = length of the triangular prism tent = 40 ft

b = base length of the triangular face = 14 ft

h = height of the triangular face = 24 ft

a = length of the rectangular floor = 40 ft

c = width of the rectangular floor = 14 ft

Surface area of the tent not including the floor = (64)(40) + (14)(24) - (40 × 14)

Surface area of the tent not including the floor = (2560) + (336) - (560)

Surface area of the tent not including the floor = 2,336 ft²

Volume of the triangular prism tent = 1/2 × 14 × 24 × 40

Volume of the triangular prism tent = 7 × 24 × 40

Volume of the triangular prism tent = 6,720  ft³

The simplified form of the given expression is, \(-36c^9\).

What is simplified form of the expression?

The fundamental guidelines and procedures to simplify any algebraic statement are as follows:

By multiplying factors, remove any grouping symbols like brackets and parenthesis.

If the words contain exponents, use the exponent rule to eliminate grouping.

Add or subtract like terms to combine them.

Add the constants together.

Consider the given expression,

\((-12c^5)(3c^4) = -36c^5c^4\)

Here, the terms \(c^5\)and \(c^4\) having the same base.

So, we can use the exponent rule,

\((a^b)(a^c) = a^b^+^c\)

⇒ \((c^5)(c^4)=c^5^+^4= c^9\)

Therefore, the expression becomes

\((-12c^5)(3c^4)=-36c^9\)

The value of a = -2 and b = 3.

What is a system of equations?

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.

Here, we have

Given: 3a - 5b = -26, a + 2b = 6

We have to solve this equation.

3a - 5b = -26...(1)

a + 2b = 6...(2)

Now we multiply equation (1) by 2 and equation (2) by 5 and we get

6a - 10b = -52....(3)

5a + 10b = 30....(4)

After solving equations (3) and (4), we get

11a = -22

a = -2

Now we put the value of 'a' in equation(3) and we get

6(-2) - 10b = -52

-10b = -52 + 12

-10b =  -30

b = 3

The probability that a randomly selected person who watched the Super Bowl saw at least one of the two ads (Amazon Alexa or Tide) is 0.8000, or option (c).

To calculate the probability, we need to find the percentage of people who saw at least one of the two ads. Let's denote:

A = the event of seeing the ad for Amazon Alexa

T = the event of seeing the ad for Tide

P(A) = probability of seeing the ad for Amazon Alexa = 0.70

P(T) = probability of seeing the ad for Tide = 0.35

P(A ∩ T) = probability of seeing both ads = 0.25

To find the probability of seeing at least one of the two ads, we can use the principle of inclusion-exclusion. The formula is:

P(A ∪ T) = P(A) + P(T) - P(A ∩ T)

Substituting the values:

P(A ∪ T) = 0.70 + 0.35 - 0.25

P(A ∪ T) = 0.80

Therefore, the probability that a randomly selected person who watched the Super Bowl saw at least one of the two ads is 0.8000, or option (c).

Based on the given information, there is an 80% chance that a person who watched the Super Bowl saw at least one of the two ads for Amazon Alexa or Tide laundry detergent.

Since none of the 13 classmates had been given math homework between the original survey and Kelly's second survey, the sum of the values in the second data set is the same as the sum of the values in the original data set. Therefore, the change in the means can be determined without calculating the mean of either data set by considering the number of data points in each set.

Since both data sets have the same number of data points, the change in the means will be zero. This is because the mean is calculated by dividing the sum of the values by the number of data points, and since the sum of the values is the same in both data sets, the means will also be the same.

In other words, if the mean of the first data set is x, then the sum of the values in the first data set is 13x (since there are 13 classmates), and the sum of the values in the second data set is also 13x (since none of the values have changed). Therefore, the mean of the second data set will also be x, and the change in the means will be zero.

A. The y-intercept is at the point (0, 0).

B.  The zeros are x = 0 or x = ±√5

C.

A) The y-intercept of this graph is the point where x = 0.

When  x = 0, the value of y

= 0^4 - 5*0^2

= 0.

Therefore, the y-intercept is at the point (0, 0).

B) The x-intercepts/roots of the function are the values of x that make y = 0.

To find these values, we need to set y = 0 and solve for x:

x⁴ - 5x² = 0

x⁴ = 5x²

x² = x⁴/5

x = ±√(x⁴/5)

We can simplify this expression by factoring x² out of both sides:

x²(x² - 5) = 0

x² = 0 or x² - 5 = 0

x = 0 or x = ±√5

hence the x-intercepts are at x = 0 and x = ±√5.

When U = 10, the value of n is 112.604.

We are given that the number n is the algebraic sum of two terms:

Term 1 varies directly as u.

Term 2 varies inversely as U².

Let's denote the first term as k1 u, where k1 is the constant of proportionality.

And let's denote the second term as k2/U², where k2 is another constant of proportionality.

We have,

When U = 2, n = 22.

When U = 8, n = 56.5.

So, Equation 1: n = k1u + k2/U²

Equation 2: 22 = k1(2) + k2/(2)²

Equation 3: 56.5 = k1(8) + k2/(8)²

Let's solve these equations to find the values of k1 and k2.

Equation 2 becomes: 22 = 2k1 + k2/4

Equation 3 becomes: 56.5 = 8k1 + k2/64

To eliminate k2, let's multiply Equation 2 by 64:

1408 = 128k1 + k2

Now we have two equations with two variables:

128k1 + k2 = 1408

8k1 + k2/64 = 56.5

Let's subtract Equation

120k1 = 1351.5

k1 = 1351.5 / 120

k1 = 11.2625

Substituting the value of k1 back into Equation 2:

22 = 2(11.2625) + k2/4

22 = 22.525 + k2/4

k2/4 = 22 - 22.525

k2/4 = -0.525

k2 = -2.1

Now we have the values of k1 and k2:

k1 = 11.2625

k2 = -2.1

Finally, we can find the value of n when U = 10 by substituting these values into Equation 1:

n = k1u + k2/U²

n = 11.2625(10) - 2.1/(10)²

n = 112.625 - 2.1/100

n = 112.625 - 0.021

n ≈ 112.604

Therefore, when U = 10, the value of n is 112.604.

Answer: y=kx

Step-by-step explanation:

The subgroup generated by these two elements has order 12, but it is not cyclic since it has two generators.

To find a cyclic subgroup of Z40 ⊕ Z30 of order 12, we can use the fact that the order of an element in a cyclic group is equal to the order of the group itself. Therefore, we need to find an element in Z40 ⊕ Z30 that has order 12. One way to do this is to consider the generator of the group, which is (1, 0). We can then find its order by repeatedly adding it to itself until we get the identity element (0, 0). We have:
(1, 0), (2, 0), (3, 0), ..., (11, 0), (12, 0) = (0, 0)
Therefore, the subgroup generated by (1, 0) has order 12 and is cyclic.
To find a non-cyclic subgroup of Z40 ⊕ Z30 of order 12, we can again use the fact that the order of an element in a cyclic group divides the order of the group. Therefore, we need to find two elements in Z40 ⊕ Z30 whose orders multiply to 12, but neither has order 12 itself. One way to do this is to consider the elements (0, 10) and (8, 0). We have:
(0, 10)^6 = (0, 0)
(8, 0)^3 = (0, 0)
Therefore, the subgroup generated by these two elements has order 12, but it is not cyclic since it has two generators.

Caitlin purchased a prepaid phone card for $20. Long distance calls cost 7 cents a minute using this card. Catin used her card only once to make a long distance all the remaining credit on her card is $16.8. how many minutes did her call last?

Answer:

45 minutes 43 seconds

Step-by-step explanation:

We are told that she purchase the prepaid phone card for $20.

Now she has $16.8 after making the call.

Therefore;

Amount spent on the call = 20 - 16.8 = $3.2

We are told that the long distance call costs 7 cents per minute. Which is $0.07 per minutes

Thus, time spent = $3.2/$0.07 = 45.714 minutes or 45 minutes 43 seconds

f ◦ g is onto, it does not guarantee that g must be onto.

If f ◦ g is onto, must g be onto? The answer is no, g does not necessarily have to be on. Let's explain this with the following steps:

1. Definition of ontological (surjective) function: A function g: A → B is onto if for every element b in the codomain B, there exists at least one element a in the domain A such that g(a) = b.

2. Definition of function composition (fg): Given two functions f: B → C and g: A → B, the composition f ◦ g: A → C is a function such that (f ◦ g)(a) = f(g(a)) for all an in A.

3. Given that f ◦ g is on, for every element c in the codomain C, there exists at least one element a in the domain A such that (f ◦ g)(a) = c.

4. However, the surjectivity of f ◦ g does not imply the surjectivity of g. This is because f may "compensate" for any lack of subjectivity in g. In other words, even if g does not map to every element in its codomain B, f might still map the outputs of g to every element in its codomain C.
