Jada flew home from vacation with a heavy bag. With the first airline she flew, jada had to pay $29 to check her bag, plus $4 for every pound that her bag was over the weight limit. The next flight was with another airline that had the same weight limit. Jada had to pay $11 per pound that her bag was over the weight limit, in addition to the checked bad fee of $15. By coincidence, the fees ended up being the same with both airlines. How far over weight limit was the bag? How large was each airlines fee?

Answer:

5.4

Step-by-step explanation:

x2-12x+36 = 90

=> 2x - 12x + 36 = *90

=> 2x - 12x = 90 - 36

=> -10x = 54

=> (-10x)/-10 = (54)/-10

=> x = 5.4

C. 240 in^2

Step-by-step explanation:

is it stated that two triangles are similar.

If they are similar then their area must be proportional too.

The side lengths' proportion is :

12/60 = 1/5 this can be used to find the area of the smaller triangle, ABC
Let x represent the are of triangle ABC

1/5 = x/1200 cross multiply both sides

5x = 1200 divide both sides by 5

x = 240 since the area is indicated with square value so the answer is

The polynomial that represents the length is:

h(x) = 11x + 1.

We know that the area of the top surface is given by:

f(x) = 66x^2 + 17x + 1

And the width of the top surface is:

g(x) = 6x + 1.

We can assume that the length, h(x), is another polynomial of degree 1, so we can write:

h(x) = a*x + b

Now, the area is the product of the width and the length, so we have:

f(x) = g(x)*h(x)

f(x) = (6x + 1)*(ax + b)

     =   6ax^2 + (6b)x + (a)x + b

     =   (6a)x^2 + (6b + a)x + b

Now let's compare this with f(x), correspondent coefficients must have the same value.

66x^2 + 17x + 1 = (6a)x^2 + (6b + a)x + b

Then we have:

66 = 6a

17 = 6b + a

1 = b

From the first equation we have:

66/6 = a = 11

And from the third:

b = 1

Then the length is:

h(x) = 11x + 1.

Answer:

x = 15/8

Step-by-step explanation:

Let x = unknown number

Given:

some number minus -15 is equal to the product of the number and 9

⇒ x - -15 = x · 9

⇒ x + 15 = 9x

⇒ 15 = 9x - x

⇒ 15 = 8x

⇒ x = 15/8

Answer:

15/8

Step-by-step explanation:

Let's assume that the number is 'n'. Provided that number 'n' minus -15 is equal to the product of the number 'n' and 9. Simply jot down the above statement in mathematical form:

[tex] \implies\:\sf{\red{n \: - \: ( - 15) \: = \: n \: \times \: 9}}[/tex]

Now, simply solve the above equation.

[tex]\implies\:\sf{n \: + \: 15 \: = \: 9n}[/tex]

Take the like terms on one sides.

[tex]\implies\:\sf{9n \: - \: n \: = \: 15}[/tex]

Do the rest calculations.

[tex]\implies\:\sf{8n \: = \: 15}[/tex]

[tex]\implies\:\sf{\red{n \: = \: \dfrac{15}{8}}}[/tex]

Hence, the required value of n is 15/8.

Step-by-step explanation:

The rule for triangles is that their angles must add up to 180. 30+50=80 and 180-80=100 so the angle next to 4 is 100. Since they are on a straight line the angle is 180 and 180-100 is 80

A confidence interval is simply the range of estimates for an unknown parameter, which is defined as an interval with a lower bound and an upper bound.

Your information is incomplete as the data is not given. Therefore, an overview of the confidence interval will be given.

A 90% confidence interval means that the researcher is 90% confident that the values of the results will simply fall between the upper and lower limits if the procedure is repeated again.

You can find a confidence level for data by simply taking half of the size of the confidence interval, then multiplying it by the square root of the sample size, and then dividing by the sample standard deviation.

Finally, look up the resulting ​Z​ or ​t​ score in a table in order to find the level.

Answer:

3/5

Step-by-step explanation:

I did this on the test and I got this specific answer correct :)

The required mean of the data set is 3/5, or approximately 0.6 inches.

The mean of the values is the ratio of the total sum of values to the number of values.

Here,
To find the mean of the data set, we need to add up all the values and divide by the total number of values.

1/4 + 1 1/3 + 2/3 + 1/4 + 1/2 = 1/4 + 4/3 + 2/3 + 1/4 + 1/2 (we convert all fractions to have a common denominator)

= 2/3 + 4/3 + 1

We need to convert these mixed numbers to improper fractions:

= 3

Now we divide by the total number of values:

= 3 ÷ 5

= 3/5

Therefore, the mean of the data set is 3/5, or approximately 0.6 inches.

The profit function of the company is the difference between the cost and the revenue functions of the company

The given parameters are:

C(x) = 60x + 300 --- the cost function

R(x) = 100x - 0.5x^2 ---- the revenue function

The profit function is calculated as:

P(x) = R(x) - C(x)

So, we have:

[tex]P(x) = 100x - 0.5x^2 - 60x - 300[/tex]

Rewrite as:

[tex]P(x) = - 0.5x^2 + 100x - 60x - 300[/tex]

[tex]P(x) = - 0.5x^2 + 40x - 300[/tex]

This means that the expression of the profit function is [tex]- 0.5x^2 + 40x - 300[/tex]

This means that:

P(x) = 50

So, we have:

[tex]- 0.5x^2 + 40x - 300 = 50[/tex]

Subtract 50 from both sides

[tex]- 0.5x^2 + 40x - 350 = 0[/tex]

Multiply through by -2

[tex]x^2 - 80x + 700 = 0[/tex]

Expand

[tex]x^2 - 70x - 10x + 700 = 0[/tex]

Factorize

[tex]x(x - 70) - 10(x - 70) = 0[/tex]

Factor out x - 70

[tex](x - 10)(x - 70) = 0[/tex]

Solve for x

x = 10 or x = 70

Hence, the two values of x that creates a profit of $50 are x = 10 and x = 70
