Answer:

it's easy u stupido perra

Step-by-step explanation:

Answer:

Your first point should be at (0,-2), because of the y intercept. Then, since the slope is 3, you want to rise 3 and run 1. Go up 3, then to the right 1. That should be  your next point. Then do it again, and again, how many ever times you need to.

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

Answer:

each student gets 3 erasers

Step-by-step explanation:

You have to divide 20 total erasers by the 6 students and you get about 3.33... and this number rounded down is 3.

Have an stupendous day! I hope this answer was helpful to you.

Each student get 3 erasers.

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.

Step-by-step explanation:

Answer: No he's wrong

Step-by-step explanation:

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 = 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°

Answer:

[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]

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

612

$612 is the full order, including the discount

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.

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.

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
