Answer: 5

Step-by-step explanation:

Answer:

[tex]\displaystyle 3x - y = 19\:or\:y = 3x - 19[/tex]

Step-by-step explanation:

Plug the information into the Slope-Intercept Formula:

[tex]\displaystyle 5 = 3[8] + b \hookrightarrow 5 = 24 + b; -19 = b \\ \\ y = 3x - 19[/tex]

Suppose you need to write this equation in standard form. You would follow these procedures:

y = 3x - 19

- 3x - 3x

__________

[tex]\displaystyle -3x + y = -19[/tex]

*Now, you can leave the standard equation like this, but UNIVERSALLY, the A-term is positive, so you must multiply the negative out as well.

[tex]\displaystyle \boxed{3x - y = 19}[/tex]

Answer:

x = 24; x = 25

Step-by-step explanation:

Question 1

x/4 = 6

x = 24  *multiply both sides by the denominator to isolate the x value

Question 2

x/2 = 12.5

x = 25 *multiply both sides by the denominator to isolate x

Step-by-step explanation:

A normally distributed set of data has been generated where 50% of the data lies below 97 and 70% lies below 104. Then, mean of the data is equal to 97 and standard deviation is equal to 13.358.

Normal distribution is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

Given that 50% of the data lies below 97, implies that median of the data is equal to 97. In a normal distribution, mean = median = mode, therefore, mean = 97.

Given the mean and value at 70th percentile, we can find the standard deviation.

Using the z score - percentile table, we find that the z score corresponding to the given percentile.

z score corresponding to 70th percentile = 0.524

[tex]0.524 = \frac{x - mean}{standard\ deviation}\\ \\0.524 = \frac{104 - 97}{standard\ deviation} \\\\standard\ deviation = \frac{7}{0.524} = 13.359[/tex]

Step-by-step explanation:

1/10 meaning for every 10 people there will be 1 person with red hair.

50 people is 10×5=50

also do it to the 1: 1×5=5

then we get a ratio of 5/50

Step-by-step explanation:

We know, that when you find the area of a quadrilateral(4 sided figure) we multiply all of the sides together.

Answer:

x = 6

Step-by-step explanation:

The perimeter is the sum of the 3 sides of the triangle. Sum the 3 sides and equate to 51, that is

15 + 5x - 6 + 2x = 51

7x + 9 = 51 ( subtract 9 from both sides )

7x = 42 ( divide both sides by 7 )

x = 6

Answer: 8/9

Step-by-step explanation:

First, we can find a common denomiator.

The least common multiple of 2, 9, and 6 is 18.

Therefore, the lcd is 18.

1/2 = 1/2 * (9/9) = 9/18

2/9 = 2/9 * (2/2) = 4/18

1/6 = 1/6 * (3/3) = 3/18

Therefore, 1/2 + 2/9 + 1/6 = 9/18 + 4/18 + 3/18.

We can add the numerators together.

= 16/18

Divide the nuumerator and denominator by 2:

= 8/9

Answer:

3 feet

Step-by-step explanation:

To begin, find the width of the first painting by dividing 32 by 4. You get 8 feet as the width. Since the second painting has a width of 8, divide 24 by 8 to get the length (area of a rectangle is length times width). You get that the length of the second painting is 3 feet.

Answer:

X = 10

Step-by-step explanation:

if we say 1/2 base = a

a² = 13² - 12²

a² = 25

a = √25

a = 5

if 1/2 base = 5 then x = a × 2

hence X = 5 × 2 = 10

Answer:

g=7

Step-by-step explanation:

10g–7g–3=18

subtract 7g from 10 g

3g-3=18

add 3 to both sides

3g=21

divide each side by 3

g=7

Answer:

g=7

Step-by-step explanation:

We move all terms to the left:

10g-7g-3-(18)=0

We add all the numbers together and all the variables

3g-21=0

We move all the terms containing "g" to the left and all the other terms to the right

3g=21

g=27/3

which is the same as

g=3

The circumference of the outer edge of the path around the pool is 113.04 ft.

The Circumference (or) perimeter of circle = 2πR. where, R is the radius of the circle.

Given

A circular swimming pool has a radius of 15 ft.

There is a path all the way around that pool that is three feet wide.

A circle has a radius of 15 feet.

A larger circle goes around the smaller circle that is 3 feet wide.

The radius of the outer edge of the path around the pool = Radius of circle + width of outer circle.

The radius of the outer edge of the path around the pool = 15 + 3

The radius of the outer edge of the path around the pool = 18ft

The circumference of the outer edge of the path around the pool is;

[tex]\rm Circumference=2\pi r\\\\Circumference = 2\times 3.14 \times 18\\\\Circumference=113.04 \ ft[/tex]

Hence, the circumference of the outer edge of the path around the pool is 113.04 ft.

Answer:

4 years

Step-by-step explanation:

Sara saved $16,000 for a new car that costs $10,500, plus $1200 each year for insurance.

Let the number of years she can pay for insurance be written as: x

$10,500 + $1200 × x = $16,000

$1200 × x = $16,000 - $10,500

x = $5,500/1200

x = 4.5833333333 years

Since the number of years is in decimal, we would pick the whole number there as the maximum number of years.

Therefore, the maximum number of years, x, she could pay insurance with her current savings is 4 years.

Step-by-step explanation:

given function: [tex]Cos(x)=\frac{1}{3}[/tex]

Cosine - (In a right triangle, the ratio of the length of the adjacent side to the length of the hypotenuse.)

#1: Take the inverse cosine of both sides of the equation to extract [tex]x[/tex] from inside the cosine.

[tex]x=arccos\frac{1}{3}[/tex]

#2: Evaluate

[tex]x=1.23095941[/tex]

#3: The cosine function is positive in the first and fourth quadrants. To find the second solution, subtract the reference angle from [tex]2[/tex]π to find the solution in the fourth quadrant.

[tex]x=2(3.14159265)-1.23095941[/tex]

#4: Simplify the equation above.

- Multiply [tex]2[/tex] by [tex]3.14159265[/tex]

[tex]x=6.2831853-1.23095941[/tex]

- Subtract [tex]1.23095941[/tex] from [tex]6.2831853[/tex]

[tex]x=5.05222588[/tex]

#5: Find the period.

- The period of the function can be calculated using [tex]\frac{2\pi }{|b|}[/tex].

[tex]\frac{2\pi }{|b|}[/tex]

- Replace [tex]b[/tex] with [tex]1[/tex]  in the formula for period.

[tex]\frac{2\pi }{|1|}[/tex]

#6: Solve the equation.

- The absolute value is the distance between a number and zero. The distance between [tex]0[/tex] and [tex]1[/tex] is [tex]1[/tex].

[tex]\frac{2\pi }{1}[/tex]

- Divide [tex]2\pi[/tex] by [tex]1.[/tex]

[tex]2\pi[/tex]

The period of the [tex]cos(x)[/tex] function is [tex]2\pi[/tex] so values will repeat every [tex]2\pi[/tex] radians in both directions.
