Donald can type 240 words in 6 minutes. How long will it take him to type a 1000-word essay if he types at the same rate?

This question can be solved by using proportions. The question has already given a proportion you need to fill in, which looks like this:

[tex]\displaystyle \frac{A}{B} =\frac{x}{1000}[/tex]

As you can see, the denominators are B and 1000, which represents the number of words. That means the number of words will go on the bottom, which leaves you with the number of minutes as the numerator.

Donald can type 240 words in 6 minutes. The number of words, 240, is the denominator, and the number of minutes, 6, is the numerator.

Substitute A and B with these values:

[tex]\displaystyle \frac{A}{B} =\frac{x}{1000} \rightarrow \frac{6}{240} =\frac{x}{1000}[/tex]

Now you need to cross multiply.

[tex]1000 \times 6=240 \times x[/tex]

Simplify:

[tex]6000=240x[/tex]

Lastly, you need to divide both sides by 240 to find the value of x alone. This is because 240 is being multiplied by x, and in order to leave x alone, you must do the opposite of it, which is dividing.

[tex]\displaystyle \frac{6000}{240} =\frac{240x}{240}[/tex]

[tex]\displaystyle x=25[/tex]

That means Donald can type 1000 words in 25 minutes. A is also equal to 6, and b is equal to 240.

__________________________________________________________

[tex]\displaystyle {\bf\frac{6}{240} =\frac{x}{1000}[/tex]

Solving this proportion indicates Donald could type his essay in 25 minutes.

Answer:

D is right

Step-by-step explanation:

The modulus increases by a factor of 10 and the argument increases by 5π/3.

The modulus of the complex number is the magnitude of the complex number. If z is the complex number such that z= p+qi

Then the modulus of the z will be =|z|= √p²+q²

We have,

z = 5 – 5i √3

So,

Now rewrite this given equation in the form of z = r(CosΘ + iSinΘ),

For this first calculate the modulus,

|Z| = √((5√3)² + 5²)

|Z| = √(25×3 + 25)

|Z| = √(100) = 10

And,

Argument, Θ = tan⁻¹ (b/a)

Θ = tan⁻¹ (5√3/5)

Θ = tan⁻¹ (√3)

Θ = 71

Therefore, the modulus increases by a factor of 10, and the argument increase by 5π/3.

Answer:

x = 1, y = 2

Step-by-step explanation:

Original equations:

[tex]x+y=3\\2x+5y=12[/tex]

Substitute y and solve for x:

[tex]y=3-x\\2x+5y=12[/tex]

[tex]2x+5(3-x)=12[/tex]

[tex]2x+15-5x=12[/tex]

[tex]x=1[/tex]

Plug in x to solve for y:

Answer:  x = -4/3

Step-by-step explanation:

3(x−4)=12x

Step 1: Simplify both sides of the equation.

3(x−4)=12x

(3)(x)+(3)(−4)=12x  (Distribute)

3x+−12=12x

3x−12=12x

Step 2: Subtract 12x from both sides.

3x−12−12x=12x−12x

−9x−12=0

Step 3: Add 12 to both sides.

−9x−12+12=0+12

−9x=12

Step 4: Divide both sides by -9.

-9x/-9 = 12/-9

The solutions of the given trigonometric equation are 60°, 180°, 300°.

A trigonometric equation is an equation that consists of one or multiple trigonometric ratios of unknown angles.

The given trigonometric equation is:

cos (x/2) - sin (x) = 0

⇒ cos (x/2) - 2sin (x/2) cos (x/2) = 0

⇒ cos (x/2) [1 - 2sin (x/2)] = 0

Therefore,  cos (x/2) = 0 = cos (90°)  (x/2 can't be 270°)

⇒ x = 180°

Again,  [1 - 2sin (x/2)] = 0

⇒ 2sin (x/2) = 1

⇒ sin (x/2) = 1/2

⇒ (x/2) = 30°, 150°

⇒ x = 60°, 300°

Answer:

x = 2

Step-by-step explanation:

The equation of a vertical line parallel to the y- axis is

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (2, 3), (2, 5), (2, 7) all with an x- coordinate 2, thus

x = 2 ← equation of vertical line

Answer:

x = 2

Step-by-step explanation:

Firstly, when a line is parallel to the y axis, the equation of the line is x = the x position common to the points, in this case, x = 2.

but if you want to calculate,

from the points,

x1 = 2, y1 = 3

x2 = 2, y2 = 5

x3 = 2, y3 = 7

using the formula,

y-y1/x-x1 = y2-y1/x2-x1

y-3/x-2 = 5-3/2-2

y-3/x-2 = 2/0

crossing we have,

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

2x - 4 = 0

2x = 4

x = 2

Answer:

x-intercept:8

y-intercept:16

Step-by-step explanation:

This is the equation of a straight line. When the line crosses the x-axis that is the x- intercept, the corresponding y-coordinate will be zero. Substituting y = 0 into the equation and solving for x gives the x-intercept.

8x-(4×0)=-64

         -8x=-64

             x=8   <=  the x-intercept.

Similarly, when the line crosses the y-axis the corresponding x- coordinate will be zero. Let x = 0 and solve for y.

(8×0)-4y=-64

        -4y=-64

           y=16    <=  the y-intercept .

Answer:

x = 1/2

y = -8

Step-by-step explanation:

Let's solve for x.

8x−4y=−64

Step 1: Add 4y to both sides.

8x−4y+4y=−64+4y

8x=4y−64

Step 2: Divide both sides by 8.

8x/8 = 4y−64 / 8

x= 1/2 y−8
