The number of chicken wings Aaron bought for 28.60 dollars is 13.

He bought 17 chicken wings for $37.40.

He spent $28.60 worth of chicken wings.

Therefore,

17 chicken wings = $37.40

1 chicken wing = ?

cross multiply

1 chicken wing = 37.40 / 17

1 chicken wing = 2.2 dollars

Therefore,

2.2 dollars = 1 chicken wing =

28.60 dollars = ?

number of chicken wings = 28.60 / 2.2

number of chicken wings = 13

The roots of the equation are 7 and -4, because 7 - 4 = 3 and 7. - 4 = -28

Step-by-step explanation:

The positive number is equal to 7.

Assuming that the number is equal to "x" we have:

[tex]\begin{gathered}x^2 = 3x + 28\\\\x^2 - 3x - 28 = 0\\\\a = 1\\\\b = -3\\\\c = -28\\\end{gathered}[/tex]

By the sum and product method, we have:

The business was valued at £17000 at the start of 2011. In 6 years, the value of this business was raised to £186000. This is equivalent to a yearly increase of 49.0%.

Given that, A=£17000, P=£186000, r=x%, t=6 years

Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest.

We know that, [tex]A=P(1+\frac{r}{100} )^{n}[/tex]

Answer: [tex]y+3=-\frac{4}{5}(x-5)[/tex]

Step-by-step explanation:

For it to bisect the segment, we need to find the midpoint.

The midpoint is [tex]\left(\frac{1+9}{2}, \frac{-8+2}{2} \right)=(5, -3)[/tex]

Now, for it to be perpendicular, we need to use the fact that perpendicular lines have slopes that are negative reciprocals of each other.

The slope of the given segment is [tex]\frac{-8-2}{1-9}=\frac{5}{4}[/tex], so the slope of the perpendicular bisector is [tex]-\frac{4}{5}[/tex]

Thus, the equation of the line in point-slope form is [tex]\boxed{y+3=-\frac{4}{5}(x-5)}[/tex]

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.

Since the number of females who are junior is 6, determine the required probability.

Taking into account the scientific notation, the result of the sum is 6.654×10¹¹.

Scientific notation is a quick way to represent a number using powers of base ten.

The numbers are written as a product:

a×10ⁿ

where:

You want to add two numbers in scientific notation:

2.04×10¹⁰ + 6.45×10¹¹

It should be noted that when the numbers to be added do not have the same base 10 exponent, the base 10 power with the highest exponent must be found. In this case, the highest exponent is 11.

Then all the values ​​are expressed as a function of the base 10 exponent with the highest exponent. In this case: 2.04×10¹⁰= 0.204×10¹¹

Taking the quantities to the same exponent, all you have to do is add what was previously called the number "a". In this case:

0.204×10¹¹ + 6.45×10¹¹= (0.204 + 6.45)×10¹¹= 6.654×10¹¹

Answer:

Buy 8 pack with £2.04 and buy 1 pack with £0.52 will be more value

Step-by-step explanation:

To calculate 1 roll:

2.04/4= £0.51

4.68/9= £0.52

(0.51+0.52)/2= £0.515 = £0.52 per roll

which pack is better value:

2.04 (4 pack) x2= £4.08 for 8 pack

4.08+0.52= £4.6 for 9 pack

£4.6<£4.68

Therefore, buy 8 pack with £2.04 and buy 1 pack with £0.52 will be more value.

Step-by-step explanation:

This question asks you to compare the coordinates of the vertex of each function.

__

The vertex of the function is its minimum, the point where the graph stops decreasing and starts increasing. It is the lowest point on the graph.

The vertex is (-4, -1). The minimum is -1, located at x = -4.

The vertex is (1, -25). The minimum is -25, located at x = 1. We know this is the minimum because there are no g(x) values that are lower (more negative).

The minimum of f(x), -1, is greater than the minimum of g(x), -25. TRUE

The x-value of f(x) at its minimum, -4, is less than the x-value of g(x) at its minimum, 1. TRUE

The sum of its first twenty terms​ is 670 if the sum of the first 10 terms of an ap is 185. If it's last term is 4 times of the second term.

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

We have the sum of the first 10 terms of an ap is 185. If it's last term is 4 times of the second term.

Let's suppose the common difference of an AP is d and the first term is 'a'.

185 = (10/2)[2a + (10-1)d]

185 = 5[2a + 9d]

37 = 2a + 9d ...(1)

a(10)  = 4a(2)            (last term is 4 times of the second term)

a + (10 - 1)d = 4(a + d)

a + 9d = 4a + 4d

3a - 5d = 0 ...(2)

After solving equation (1) and (2) we get:

a = 5

d = 3

The sum of the first 20 terms:

S(20) = (20/2)[2×5 + (20-1)3]

S(20) = 10[10 + 57]

S(20) = 670

Thus, the sum of its first twenty terms​ is 670 if the sum of the first 10 terms of an ap is 185. If it's last term is 4 times of the second term.
