A man can make 12 birdhouses in 8 hours. How many hours will it take him to make 30 birdhouses?

An equation is marked out by the presence of the equality sign. From the calculation, the solution to the equation is x = 12/37.

The term equations refers to any mathematical statement that involves the equality sign.

Here we have the equation;  37x = 12, the first step is to divide both sides by 37 as shown;

37x/37 = 12/37

This leaves us with the result x = 12/37 which is the solution to the equation.

Step-by-step explanation:

The factor of the given equation will be  [tex](12+7x)(12-7x)[/tex]

The given expression is

[tex]=144-7x^2[/tex]

Now we can also write this

[tex]=(12^2-7x^2)[/tex]

By using the formula

[tex](a^2-b^2)=(a+b)(a-b)[/tex]

Now form the above formula

[tex]=(12+7x)(12-7x)[/tex]

Thus the factor of the given equation will be  [tex](12+7x)(12-7x)[/tex]

Answer and explanation:

There should be 85.6% correctly made products

If there is less than 85.6% correctly made products then production would be shut down

therefore 100-85.6= 14.4% of products can be incorrectly made and not more than that

In 30 batches 14.4% =0.144*30=4.32 products

Therefore there must not be more than 4.32 products incorrectly made in a batch of 30 else production is shut down

Step-by-step explanation:

Alex gets paid for $6.00 PER hour

In June:

Alex worked for 11 hours.

In July:

19 hours.

You can do 19*6.00 (Lets just do 19*6 for now to make it easier)

19*6=114

Change it to $144.00

In June:

You can do 11*$6.00. '(Lets just do 11*6 for now to make it easier)

11*6=66.

Change it to $66.00

Add the money Alex earned.

Answer:

6.18 ft

Step-by-step explanation:

The ramp forms a right triangle.

We know two of the lengths of the right triangle, therefore, we would apply pythagorean theorem to find the longest length of the triangle, which is the length of the ramp.

The given lengths are 1.5 ft and 6 ft. The length of the ramp is the length of the longest side (hypotenuse length).

Thus, applying pythagorean theorem:

[tex] c^2 = a^2 + b^2 [/tex], where,

a = 1.5 ft

b = 6 ft

c = length of ramp

Substituting the values:

[tex] c^2 = 1.5^2 + 6^2 [/tex]

[tex] c^2 = 2.25 + 36 [/tex]

[tex] c^2 = 38.25 [/tex]

[tex] \sqrt{c^2} = \sqrt{38.25} [/tex]

[tex] c = \sqrt{38.25} [/tex]

[tex] c = 6.18 [/tex] (nearest hundredth)

length of the ramp = 6.18 ft

Subproblem 1

Set the factor '(6c + -7d)' equal to zero and attempt to solve:

Simplifying

6c + -7d = 0

Solving

6c + -7d = 0

Move all terms containing c to the left, all other terms to the right.

Add '7d' to each side of the equation.

6c + -7d + 7d = 0 + 7d

Combine like terms: -7d + 7d = 0

6c + 0 = 0 + 7d

6c = 0 + 7d

Remove the zero:

6c = 7d

Divide each side by '6'.

The required equation of the line in slope intercept form is given as 2x + y = 3

Given that,
To determine the linear equation in slope-intercept form passing through the point with the given slope. (0, 3); slope = -2.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Equation of the line is given as,

y - y₁ = m (x - x₁)
Substitute the value in the equation,

y - 3 = -2 (x - 0)
y = -2x + 3
2x + y = 3

Thus, the required equation of the line in slope intercept form is given as 2x + y = 3

Step-by-step explanation:

Answer:

[tex]y-7=-6(x-1)[/tex]

Step-by-step explanation:

So first you need to find the slope of the line. You do this by doing [tex]m=\frac{y^{2}-y^{1}}{x^{1}-x^{2}}[/tex]. You would plug the points from the line into the equation to get [tex]m=\frac{1-7}{5-4}[/tex], and when you simplify you would get [tex]m=\frac{-6}{1}[/tex] or [tex]m=-6[/tex]. This means your slope is -6.

Now, point slope form is written as [tex]y-y^{1} = m(x-x^{1} )[/tex] so to write the equation you would plug in the slope and the first point to get [tex]y-7=-6(x-1)[/tex]
