Answer:

[tex] \Large{\boxed{\sf n = 8}} [/tex]

[tex] \\ [/tex]

Explanation:

The perimeter of a rectangle is given by the following formula:

[tex] \Large{\sf P = 2L + 2W } [/tex]

Where:

P is the perimeter of the rectangle.L is its length.W is its width.

[tex] \\ [/tex]

[tex] \Large{\boxed{\sf Given \text{:} } \begin{cases} \sf L &=\sf 3n - 9 \\ \sf W &=\sf n + 5 \\ \end{cases} } [/tex]

[tex] \\ [/tex]

Substitute these values into our formula:

[tex] \sf P = 2(3n - 9) + 2(n + 5) [/tex]

[tex] \\ [/tex]

Expand the expression of the perimeter using the following distributive property.

[tex]\green{\begin{gathered}\begin{gathered} \\ \boxed { \begin{array}{c c} \\ \blue{ \sf\boxed{ \sf Distributive \: property \text{ : } }} \\ \\ \sf\star \: \red{ \large{ a (b + c) = ab + ac }} \end{array}}\\\end{gathered} \end{gathered}}[/tex]

[tex] \\ [/tex]

We get:

[tex] \sf P = 2(3n) + 2(-9) + 2n + 2(5) \\ \\ \sf P = 6n - 18 + 2n + 10 \\ \\ \boxed{\sf P = 8n - 8 } [/tex]

[tex] \\ [/tex]

Since the perimeter is equal to 56, the value of n satisfies the following equality:

[tex] \sf 8n - 8 = 56 [/tex]

[tex] \\ [/tex]

To solve this equation, let's add 8 to both sides:

[tex] \sf 8n - 8 + 8 = 56 + 8 \\ \\ \sf 8n = 64 [/tex]

[tex] \\ [/tex]

Now, divide both sides of the equation by 8:

[tex] \sf \dfrac{8n}{8} = \dfrac{64}{8} \\ \\ \\ \boxed{\boxed{\sf n = 8}} [/tex]

[tex] \\ \\ [/tex]

Answer:

A. The slope is  [tex]\frac{3}{2}[/tex]

B.  the slope of the tangent line at x = 1 is also the instantaneous rate of change at that point.

Step-by-step explanation:

PART A: Slope

Given tangent line;

[tex]y = \frac{3x}{2} + \frac{9}{2}[/tex]

The slope of the tangent line is equal to the derivative of the function;

[tex]\frac{dy}{dx} =\frac{3}{2}[/tex]

the slope = [tex]\frac{3}{2}[/tex]

PART B: Correct statement that describe the slope of a tangent line:

A secant line is a straight line joining two points on a function and the slope of the function is equal to average rate of change of the function between the two points.

A tangent line is a straight line that touches a function at only one point, and the slope of the function is equal to the instantaneous rate of change of the function at that one point.

Thus, the correct statement is " the slope of the tangent line at x = 1 is also the instantaneous rate of change at that point".

Please show all working
thanks

Answers

Answer:

a) (i) 1200

b) (ii) 3750

c) (i) [tex]\frac{3}{20}[/tex]

Step-by-step explanation:

a) Total number of students = 5000

Ratio of teachers to students = 6 : 25

i) Number of teachers = ?

By the given ratio, we can let the number of teachers = 6[tex]x[/tex]

and we can let the number of students = 25[tex]x[/tex]

[tex]25x = 5000\\\Rightarrow x = 200[/tex]

Therefore, number of teachers = 6 [tex]\times[/tex] 200 = 1200

b) A Quarter of the students own i-phone classic 20.

ii) Number of students who do not own an i-phone classic?

As per question statement,

Number of students who own i-phone classic 20 = [tex]\frac{1}{4}\times 5000[/tex] = 1250

Number of students who do not own i-phone classic 20 = 5000 - 1250 = 3750

c) Number of students who own samsung galaxy a80s = 60% of students who own i-phone classic 20 = [tex]\frac{60}{100}\times 1250[/tex] = 750

Fraction of students who own samsung galaxy a80s = Number of students having samsung a80s divided by total number of students

[tex]\dfrac{750}{5000} = \dfrac{3}{20}[/tex]

What is an equation of the line that passes through the points (5,2) and (-5, -6)?

Answers

Answer:

y=4/5x+2

Hi! first things first, you want to find the slope. you do that by taking both y values, in this case they are 2 and -6.

then, you need to identify the two 2 x values, 5 and -5.

next, follow this formula: Y2-Y1/X2-X1. y value#2 is -6, and y value#1 is 2. subtract those numbers, to end up with -8. this will go on top of the fraction.  x value#2 is -5, x value#1 is 5. subtract (=-10) and put it on the bottom of the fraction.

now you have your slope! we now have y= -8/-10, or simplified is 4/5.

Now we find the y intercept. to do that, you want to pick a set of points. i'm going to be using (5, 2) because it will be the easiest.

lastly, set up the equation to find the y int: y- y1= m (x- x1)

y- 2= 4/5 (x- 5) = 2

Share $112 in the ratio 10:18 PLZ HELP

Answers

Answer:

$40 and $72, see below :)

Step-by-step explanation:

One way we can do this is to add the total ratios and then divide that from 112.

10x + 18x = 28x = 112

28x = 112

x = 4

That means, for every ratio, you just have to multiply the amount by 4.

so for example, 10 is just 10 * 4 = 40

So, your answer would be you share the money into $40 and $72

13) v2 - 110 + 18 = 0
14) 5x7 - 12x +7 = 0
Solve by factoring

Answers

Answer:

see explanation

Step-by-step explanation:

(13)

v² - 11v + 18 = 0 ← in standard form

(v - 2)(v - 9) = 0 ← in factored form

Equate each factor to zero and solve for v

v - 2 = 0 ⇒ v = 2

v - 9 = 0 ⇒ v = 9

solutions are v = 2, v = 9

(14)

5x² - 12x + 7 = 0

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 5 × 7 = 35 and sum = - 12

The factors are - 5 and - 7

Use these factors to split the x- term

5x² - 5x - 7x + 7 = 0 ( factor the first/second and third/fourth terms )

5x(x - 1) - 7(x - 1) = 0 ← factor out (x - 1) from each term

(x - 1)(5x - 7) = 0

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

5x - 7 = 0 ⇒ 5x = 7 ⇒ x = [tex]\frac{7}{5}[/tex]

solutions are x = 1, x = [tex]\frac{7}{5}[/tex]

In a survey of 1,700 people who owned a certain type of​ car, 425 said they would buy that type of car again. What percent of the people surveyed were satisfied with the​ car?

Answers

Answer:

25%

Step-by-step explanation:

Given;

Total people surveyed = 1700 people

Total number of people that owned car = 425 people;

Percentage of people satisfied are those that owned car = 425/1700 * 100

Percentage of people satisfied = 42500/1700

Percentage of people satisfied = 25%

Hence 25% of the people surveyed were satisfied with the​ car

1. Find the area of each sector. Give your answer in two forms. 1) in terms of it and 2) using 3.14 for it.
Round all answers to the nearest tenth.

Answers

Answer:

1.

1) The area of the sector is 168.8π mi²

2) The area of the sector is 529.9 mi²

2.

1) The area of the sector is 42.3π in²

2) The area of the sector is 132.7 in²

Step-by-step explanation:

The formula of the area of a sector in a circle is A = [tex]\frac{x}{360}[/tex] × π r², where

x is the central angle subtended by the arc of the sectorr is the radius of the circle

1.

∵ The central angle subtended by the arc of the circle is 270°

x = 270°

∵ The radius of the circle is 15 mi.

r = 15

→ Substitute them in the formula of the area above

∵ A = [tex]\frac{270}{360}[/tex] × π (15)²

∴ A = 168.75π mi²

→ Round it to the nearest tenth

∴ A = 168.8π mi²

1) The area of the sector is 168.8π mi²

∵ π = 3.14

∴ A = 168.75 × 3.14

∴ A = 529.875 mi²

→ Round it to the nearest tenth

∴ A = 529.9 mi²

2) The area of the sector is 529.9 mi²

2.

∵ The central angle subtended by the arc of the circle is 90°

x = 90°

∵ The radius of the circle is 13 in

r = 13

→ Substitute them in the formula of the area above

∵ A = [tex]\frac{90}{360}[/tex] × π (13)²

∴ A = 42.25π in²

→ Round it to the nearest tenth

∴ A = 42.3π in²

1) The area of the sector is 42.3π in²

∵ π = 3.14

∴ A = 42.25 × 3.14

∴ A = 132.665 in²

→ Round it to the nearest tenth

∴ A = 132.7 in²

2) The area of the sector is 132.7 in²
