Linear Modeling

It's given a situation where a student has two summer jobs and wants to collect $750 to pay for a down payment on a car. He gets paid $25 for each lawn mowed and $15 for each pool cleaned

Create a model in standard form

Let

x = number of lawns mowed

y = number of pools cleaned

He wants to make $750, thus:

25x + 15 y = 750

Dividing by 5, we have the model that represents the linear relationship:

5x  + 3y = 150

Identify the x-intercept

The x-intercept can be found by setting y=0:

5x  + 3(0) = 150

5x = 150

Dividing by 5:

x = 150/5 = 30

x = 30

This represents the situation where the student gets his $750 by only mowing 30 lawns, no pools cleaned.

Identify the y-intercept

The y-intercept can be found by setting x =0:

5(0)  + 3y = 150

3y = 150

y = 150/3 = 50

y = 50

This represents the situation where the student gets his $750 by only cleaning 50 pools, no lawns mowed.

Identify two combinations that are solutions to the equation

Starting from the basic equation

5x  + 3y = 150

We can give x some arbitrary value (less than 30) and find the value for y.

For example, for x=12

5*12 + 3y = 150

60 + 3y = 150

3y = 150 - 60 = 90

y = 90/3=30

This solution corresponds to the case where the student gets $750 by mowing 12 lawns and cleaning 30 pools.

For example, for x=21

5*21 + 3y = 150

105 + 3y = 150

3y = 150 - 105 = 45

y = 45/3=15

This solution corresponds to the case where the student gets $750 by mowing 21 lawns and cleaning 15 pools.

Which is the solution for 3 (10x+4) = 8(3x + 6)

Answers

Answer:

x=6

Step-by-step explanation:

Answer:

3(10x+4)=8(3x+6)

Step 1: Simplify both sides of the equation.

3(10x+4)=8(3x+6)

(3)(10x)+(3)(4)=(8)(3x)+(8)(6)(Distribute)

30x+12=24x+48

Step 2: Subtract 24x from both sides.

30x+12−24x=24x+48−24x

6x+12=48

Step 3: Subtract 12 from both sides.

6x+12−12=48−12

6x=36

Step 4: Divide both sides by 6.

6x = 36

Answer:

x=6

A go-kart's gas tank holds 6 gallons of gasoline which will last 228 miles. How many miles can the go kart travel on 1 gallon of gasoline?

Answers

Answer:

1 mile of gas will go 38 miles.

Step-by-step explanation:

If 6 gallons goes 228 miles, how many does 1 gallon go? You would have to divide 228 by 6 in order to find how many miles are in one gallon.

OR, if you prefer algebra:

228 miles/ 6 gallon = (x) miles/ 1 gallon

Which would be 228/6 = x/1

What is the value of x? Enter your answer in the box.

Answers

Answer:

x = 61°

Step-by-step explanation:

Property of a triangle,

Sum of interior angles of a triangle = 180°

By applying this property in ΔABC,

m∠A + m∠B + m∠C = 180°

x° + 67° + 52° = 180°

x + 119° = 180°

x = 180 - 119

x = 61°

Therefore, measure of angle A = x = 61°

Answers

Answer:

a) 0≠ -10

b) x= -3

c)y= 0

Step-by-step explanation:

a) 3-4x=-7-4x

[tex]3-4x=-7-4x\\Adding \ 4x \ on \ both \ sides\\3-4x+4x=-7-4x+4x\\3-0=-7\\Adding \ -3\\3-0-3=-7-3\\0\neq -10[/tex]

So, this equation has no solution as both sides are not equal.

b) [tex]15-2x=-7x[/tex]

Solving:

[tex]15-2x=-7x\\Adding \ 2x \ on \ both \ sides\\15-2x+2x=-7x+2x\\15=-5x\\Divide \ both \ sides \ by -5\\x=-3[/tex]

So, this equation has one solution

c) 7(y-3)=6y-21

Solving:

[tex]7(y-3)=6y-21\\7y-21=6y-21\\Adding \ -6y \ on \ both \ sides\\7y-21-6y=6y-21-6y\\y=-21+21\\y=0[/tex]

So, this equation has one solution.

1. Write equation with no solution. 3-4x=-7-4x (check solution of a)

2. Write equation with one solution. 7(y-3)=6y-21 (check solution of c)

3. Write equation with infinite solution. 2x + 3 = x + x + 3

solving:

2x+3=2x+3

2x-2x+3=3

3=3

When both sides are equal, the equation has infinite solutions.

Find the exact value of sin A in simplest radical form.

Answers

Answer:

[tex] \sin A= \frac {1} {\sqrt {82}}[/tex]

Step-by-step explanation:

[tex]\sin A= \frac {BC} {BA} \\\\

\sin A= \frac {1} {\sqrt {82}} \\\\[/tex]

The exact value of sin A in simplest radical form is  1 /√82.

What is sine?

In trigonometry, the sine function can be defined as the ratio of the length of the opposite side to that of the hypotenuse in a right-angled triangle.

Now from the given triangle we have,

Hypotenuse, AB = √82

Perpendicular, BC = 1

Base, AC = 9

Since, sine function is the  ratio of the length of the opposite side to that of the hypotenuse.

Thus, Sin A = Perpendicular / Hypotenuse

⇒ Sin A = 1 /√82

which is the required the exact value of sin A in simplest radical form.

Thus, the exact value of sin A in simplest radical form is  1 /√82

A baseball bat cost $30 each from a manufacturer. If a store purchases more than 10 bats, the store receives a 15% discount on the total order. A store ordered 24 bats. What was the total amount of the order before sales tax?

Answers

Answer:

$612 was the total amount of the order before sales tax.

Step-by-step explanation:

30 × 24

720

$720 is the full order without the discount being applied

24 is more than 10 bats so the discount will be applied

Convert the percentage into a decimal (move the decimal place two places to the left)

(30 × 24) × (.15)

720 × .15

108

$108 is the discount off the full order of 24 bats

720 - 108

C. 1

Step-by-step explanation:

Given

ΔABC withSlope of AB = -1∠ABC = 90°

This means that AB⊥BC

The dilation doesn't affect the shape of the triangle, therefore:

A'B' has slope of -1B'C' ⊥ A'B'

Perpendicular lines have negative reciprocal slopes. In other words the product of the slopes is  - 1.

Let the slope of B'C' is x, then:

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Total number of students = 6

Number of erasers = 20

Now,

Since, Total number of students = 6

And, Number of erasers = 20

Hence, Number of eraser getting by each students = 20 ÷ 6

                                                                   = 3.33

Thus, Each student get 3 erasers.

[tex]AB = \sqrt{a^2 + b^2-2abCos\ C}[/tex]

Step-by-step explanation:

Given:

The above triangle

Required

Solve for AB in terms of a, b and angle C

Considering right angled triangle BOC where O is the point between b-x and x

From BOC, we have that:

[tex]Sin\ C = \frac{h}{a}[/tex]

Make h the subject:

[tex]h = aSin\ C[/tex]

Also, in BOC (Using Pythagoras)

[tex]a^2 = h^2 + x^2[/tex]

Make [tex]x^2[/tex] the subject

[tex]x^2 = a^2 - h^2[/tex]

Substitute [tex]aSin\ C[/tex] for h

[tex]x^2 = a^2 - h^2[/tex] becomes

[tex]x^2 = a^2 - (aSin\ C)^2[/tex]

[tex]x^2 = a^2 - a^2Sin^2\ C[/tex]

Factorize

[tex]x^2 = a^2 (1 - Sin^2\ C)[/tex]

In trigonometry:

[tex]Cos^2C = 1-Sin^2C[/tex]

So, we have that:

[tex]x^2 = a^2 Cos^2\ C[/tex]

Take square roots of both sides

[tex]x= aCos\ C[/tex]

In triangle BOA, applying Pythagoras theorem, we have that:

[tex]AB^2 = h^2 + (b-x)^2[/tex]

Open bracket

[tex]AB^2 = h^2 + b^2-2bx+x^2[/tex]

Substitute [tex]x= aCos\ C[/tex] and [tex]h = aSin\ C[/tex] in [tex]AB^2 = h^2 + b^2-2bx+x^2[/tex]

[tex]AB^2 = h^2 + b^2-2bx+x^2[/tex]

[tex]AB^2 = (aSin\ C)^2 + b^2-2b(aCos\ C)+(aCos\ C)^2[/tex]

Open Bracket

[tex]AB^2 = a^2Sin^2\ C + b^2-2abCos\ C+a^2Cos^2\ C[/tex]

Reorder

[tex]AB^2 = a^2Sin^2\ C +a^2Cos^2\ C + b^2-2abCos\ C[/tex]

Factorize:

[tex]AB^2 = a^2(Sin^2\ C +Cos^2\ C) + b^2-2abCos\ C[/tex]

In trigonometry:

[tex]Sin^2C + Cos^2 = 1[/tex]

So, we have that:

[tex]AB^2 = a^2 * 1 + b^2-2abCos\ C[/tex]

[tex]AB^2 = a^2 + b^2-2abCos\ C[/tex]

Take square roots of both sides

[tex]AB = \sqrt{a^2 + b^2-2abCos\ C}[/tex]
