Write an equation in slope-intercept form
of the line that passes through the point
(-12,6) and is perpendicular to the line
X= - 3/4y -5 ( What would be my first step to put that equation into slope intercept form?) 

Answers

Hint :-

The product of slopes of two perpendicular lines is -1 . The slope intercept form of the line is [tex] y = mx + c [/tex] .The point slope form of the line is [tex] m(x-x_1) = (y-y_1) [/tex]

Solution :-

The given equation to us is ,

[tex]\implies x = \dfrac{-3}{4}y - 5 [/tex]

Convert it to slope intercept form we have ,

[tex]\implies 4x =-3y -20 \\\\\implies 3y = -4x -20 \\\\\implies y =\dfrac{-4}{3}x -\dfrac{20}{3}[/tex]

On comparing to the slope intercept form of the line we have ,

[tex]m = \dfrac{-4}{3}[/tex]

As we know that the product of slopes of two perpendicular lines is-1 , henceforth ,

[tex] m_{perp}= \dfrac{3}{4}[/tex]

Now using slope point form rewrite the equation of the perpendicular line ,

[tex]\implies y-y_1 = m(x-x_1) \\\\\implies y -6 = \dfrac{3}{4}(x+12)\\\\\implies 4y -24 = 3x + 36 \\\\\implies 3x -4y +36+24=0\\\\\implies \underline{\boxed{ \gray{3x -4y +60=0}}}[/tex]

A brick of himalayan salt measures 20 x 10 x 4 and weighs 1 kg and 600 gs. then the density will be; 0.002 kg/cubic unit.

How are density, volume and mass of a substance related?

Density is like rate. It tells you how much of a thing is available for each unit other thing which contains the first thing. Suppose that a finite amount of substance is there having its properties as:

mass of substance = m kg

density of substance = d kg/m³

volume of that substance = v m³

Then, they are related as:

d = m/v

Given that a brick of himalayan salt measures 20 x 10 x 4 and weighs 1 kg and 600 gs.

Density = Mass / Volume

Density = 1.6 kg / 20 x 10 x 4

= 0.002 kg/cubic unit.

Write an
equivalent fraction for 2/5 with 45 as the denominator.

Answers

Answer:

18/45

Step-by-step explanation:

First you set 2/5 equal to x/45.

Then you see what number you need to multiply 5 by to get 45

Multiply 2 by the number you got and you get x.

The equivalent fraction for 2/5 with a denominator of 45 is 18/45.

We need to figure out what number we can multiply the numerator and denominator by to get the necessary denominator in order to discover an equivalent fraction for 2/5 with a denominator of 45.

The denominator must be multiplied by 9 in order to be converted from 5 to 45 (45 ÷ 5 = 9). To keep the ratio and get the equal fraction, we will also multiply the numerator by 9.

2/5 x 9/9 = (2 x 9) / (5 x 9) = 18/45

As a result, 18/45 is the corresponding fraction for 2/5 with a denominator of 45.

Hello,

Correct Answer is 12/3

Step-by-step explanation:-

For angle theta, perpendicular side is AB=12 and hypotenuse side is BC=13.

The sine of angle is equal to the ratio of perpendicular side to the hypotenuse side. So, sine of angle theta is:-

[tex]sin \: θ = \frac{12}{3} [/tex]

So, sine ratio angle is 12/3.

4. As Jody dives below the water, its temperature decreases by 0.3 degrees Fahrenheit per foot that he dives. If
Jody is diving at a rate of 2.5 feet per second and the water at the surface is at a temperature of 68 degrees
Fahrenheit then what is the temperature of the water Jody is in after diving for 20 seconds?

Answers

Using proportions and a linear function, it is found that the temperature of the water Jody is in after diving for 20 seconds is of 53 degrees Fahrenheit.

Jody is diving at a rate of 2.5 feet per second, thus, after 20 seconds, his depth is of:

[tex]20 \times 2.5 = 50[/tex]

The temperature at the surface is of 68 degrees. For each foot, it decreases by 0.3 degrees. Thus, the function is:

[tex]T(f) = 68 - 0.3f[/tex]

Jody is at a depth of 50 feet, thus the temperature is T(50).

[tex]T(50) = 68 - 0.3(50) = 53[/tex]

The temperature of the water Jody is in after diving for 20 seconds is of 53 degrees Fahrenheit.

A coated heavy- gauge plastie pipeline can be installed, with pumps spaced appropriately along the pipeline. Alternatively, canal can be built; however, it will have greater water loss than the pipeline, due to evaporation and poaching along the canal route. To compensate for the water loss, the canal will have a greater carrying capacity than the pipeline. It is estimated it will cost $125 million to install the pipeline. Major replacements are planned every 15 years at the cost of $10 million. Pumping and other annual operating and maintenance costs are estimated to be $5 million. The canal will cost $200 million to construct; its annual operating and maintenance costs are anticipated to be S1 million.
