Answer:

Ian need to keep the website for site B less than 10 months

Step-by-step explanation:

Let

x -----> the number of months

y ----> the cost for website hosting

we know that

Site A

[tex]y=4.95x+49.95[/tex] -----> equation A

Site B

[tex]y=9.95x[/tex] -----> equation B

Equate equation A and equation B and solve for x

[tex]9.95x=4.95x+49.95[/tex]

[tex]9.95x-4.95x=49.95[/tex]

[tex]5x=49.95[/tex]

[tex]x=9.99\ months[/tex]

Round the number of months

[tex]x=10\ months[/tex]

For x=10 months ----> the cost for website hosting is the same in both sites

For x>10 months ---> the cost for website hosting is less expensive in site A

For x<10 months ---> the cost for website hosting is less expensive in site B

therefore

Ian need to keep the website for site B less than 10 months

When comparing the two hosting sites, Site B becomes cheaper than Site A after around 10 months, if the website is kept active during this period. This calculation is made by setting up an equation for the costs and solving for the number of months.

When Ian wants to promote his band on the Internet by creating a website, he needs to make a decision about the cost effectiveness between the two hosting sites. Let's break down the costs for each site:

To find out when Site B would be cheaper than Site A, we need to set up an equation where the left-hand side is the cost for Site A and the right-hand side is the cost for Site B. The equation would therefore be, $49.95 + $4.95n (with n being the number of months) = $9.95n.

To solve for n, subtract $4.95n from both sides leaving $49.95 = $5n. Dividing $49.95 by $5 gives us n = 9.99, which means after around 10 months, Site B becomes cheaper than Site A provided Ian keeps the site active.

Equation: [tex]3(x-6)^2=12[/tex]

Solutions: [tex]x=4\text{ or }x=8[/tex]

Step-by-step explanation:

Unknown variable [tex]= x[/tex]

Difference of x and 6 [tex]= x - 6[/tex]

Square of the difference of x and 6 [tex]=(x-6)^2[/tex]

Three times the square of the difference of x and 6 [tex]=3(x-6)^2[/tex]

Three times the square of the difference of x and 6 is 12, then

[tex]3(x-6)^2=12[/tex]

Divide this equation by 3:

[tex](x-6)^2 =4[/tex]

Now

[tex]x-6=2\text{ or }x-6=-2\\ \\x=2+6\text{ or }x=-2+6\\ \\x=8\text{ or }x=4[/tex]

Answer:

The value of b is 12.9 cm

The value of a is 15.3 cm

Step-by-step explanation:

see the attached figure to better understand the problem

Find the value of b

we know that

in the right triangle ABC

The function sine of angle of 40 degrees is equal to divide the opposite side to the angle of 40 degrees (AC) by the hypotenuse (AB)

so

[tex]sin(40\°)=AC/AB[/tex]

Solve for AC

[tex]AC=(AB)sin(40\°)[/tex]

substitute the given value

[tex]AC=(20)sin(40\°)[/tex]

[tex]AC=12.9\ cm[/tex]

therefore

The value of b is 12.9 cm

Find the value of a

we know that

in the right triangle ABC

The function cosine of angle of 40 degrees is equal to divide the adjacent side to the angle of 40 degrees (BC) by the hypotenuse (AB)

so

[tex]cos(40\°)=BC/AB[/tex]

Solve for BC

[tex]BC=(AB)cos(40\°)[/tex]

substitute the given value

[tex]BC=(20)cos(40\°)[/tex]

[tex]BC=15.3\ cm[/tex]

therefore

The value of a is 15.3 cm

Answer:

720 shares

Step-by-step explanation:

Find 60% of 1,200, to figure out how many shares Jillian has.

Change 60% to decimal

0.6

Multiply with the total shares

0.6 x 1,200 = 720

720 shares

Jillian owns 720 shares in a catering corporation.

The percentage is defined as a ratio expressed as a fraction of 100.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operation is called the arithmetic operator.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

We have to determine 60% of 1,200, to figure out how many shares Jillian has.

Convert 60% into a decimal

⇒ 0.6

Multiply with the total shares

⇒ 0.6 × 1200

⇒  720

Hence, Jillian owns 720 shares in a private catering corporation.

Answer:

The running club has 35 members

Step-by-step explanation:

Let

x ----> the total members of the running club

we know that

The total members of the running club multiplied by 5/7 plus 6 must be equal to 31 people

so

[tex]\frac{5}{7}x+6=31[/tex]

Solve for x

[tex]\frac{5}{7}x=31-6[/tex]

Probability of a male having a blood circulation problem, given he's a smoker, is approximately 0.6667.

Step 1:

Identify the given probabilities:

Let [tex]\( P(A) \)[/tex] be the probability that a randomly chosen male has a blood circulation problem, which is [tex]\( 0.25 \)[/tex].

Let [tex]\( P(B|A) \)[/tex] be the probability that a male is a smoker given that he has a blood circulation problem, and it's twice the probability of being a smoker given not having a blood circulation problem.

Step 2:

Calculate [tex]\( P(B|\neg A) \)[/tex]:

Since males with blood circulation problems are twice as likely to be smokers as those without, \( P(B|\neg A) \) is half of [tex]\( P(B|A) \)[/tex], which is [tex]\( \frac{1}{2} \)[/tex].

Step 3:

Apply Bayes' theorem:

[tex]\[ P(A|B) = \frac{P(B|A) \times P(A)}{P(B)} \][/tex]

Step 4:

Calculate \( P(B) \):

[tex]\[ P(B) = P(B|A) \times P(A) + P(B|\neg A) \times P(\neg A) \][/tex]

Step 5:

Substitute values into Bayes' theorem and solve:

[tex]\[ P(A|B) = \frac{(2 \times P(B|\neg A)) \times P(A)}{(2 \times P(B|\neg A)) \times P(A) + P(B|\neg A) \times (1 - P(A))} \]\[ P(A|B) = \frac{(2 \times \frac{1}{2}) \times 0.25}{(2 \times \frac{1}{2}) \times 0.25 + \frac{1}{2} \times (1 - 0.25)} \]\[ P(A|B) = \frac{0.25}{0.25 + 0.125} \]\[ P(A|B) = \frac{0.25}{0.375} \]\[ P(A|B) \approx 0.6667 \][/tex]

Thus, the probability that a male has a blood circulation problem, given that he is a smoker, is approximately 0.6667.

Answer:

72.5 miles/hour

Step-by-step explanation:

When we say "miles per hour" in English this just is simply the question "If Bailey drove for only one hour, how far did she go?". Now mathematically we can find this very easily by simply dividing 290 by 4, which is equal to 72.5. So Bailey travels 72.5 miles every hour.  

If it is confusing about why we do this, think about splitting up 290 miles evenly between 4 hours, how many miles does each hour 'get'. Each would 'get' 72.5 miles. So for every hour Bailey drives she travels 72.5 miles which is the same as saying that she drove at 72.5 miles per hour.

The vertical distance is 25.825 ft

Step-by-step explanation:

we know that

To find out the vertical distance between Cece and the base of the mountain, subtract the height of the base of the mountain from the height of Cece

Let

x -----> the height of Cece

y ----> the height of the base of the mountain

we have

[tex]x=15\frac{5}{8}\ ft[/tex] ----> is positive because is above sea level

convert to an improper fraction

[tex]x=15\frac{5}{8}\ ft=\frac{15*8+5}{8}=\frac{125}{8}=15.625\ ft[/tex]

[tex]y=-10.2\ ft[/tex] -----> is negative because is below sea level

Answer:

C. [tex]h(x)=x-3[/tex]

Step-by-step explanation:

We have been given a function [tex]f(x)=x+3[/tex]. We are asked to find the inverse of the given function.

First of all, we will replace [tex]f(x)[/tex] by y as:

[tex]y=x+3[/tex]

Now, we will interchange x and y variables as:

[tex]x=y+3[/tex]

Solve for y:

[tex]x-3=y+3-3[/tex]

[tex]x-3=y[/tex]

Switch sides:

[tex]y=x-3[/tex]

Therefore, the inverse function for the given function would be [tex]h(x)=x-3[/tex].

2(-10) = (-12) - 6

-20 ≠ -18

Incorrect.

--------------------------------

Lets try -1:

2(3(-1) - 1) = 4(-1) - 6

2(-3 - 1) = (-4) - 6

-8 ≠ -10

Incorrect.

--------------------------------

So all the options are incorrect.

2(3x - 1) = 4x - 6

(2 * 3x) + (2 * -1) = 4x + (-6)

6x + (-2) = 4x + (-6)

6x - 2 = 4x - 6

6x - 2 - 4x = 4x - 6 - 4x

2x - 2 = -6

2x + 2 - 2 = -6 + 2

2x = -4

2x/2 = -4/2
