A line passes through the point ( -10, 4) and has a slope of 1/2
Write an equation in point slope form for this line,

Answers

Answer:

[tex]y-4=\frac{1}{2} (x+10)[/tex]

Step-by-step explanation:

Point-slope form: [tex]y-y_1=m(x-x_1)[/tex] when the given point is [tex](x_1,y_1)[/tex] and the slope is [tex]m[/tex]

[tex]y-y_1=m(x-x_1)[/tex]

A store advertises 15% off an item that regularly sells for $300

what is the price of the item?

Answers

The item would sell for $255 if it had a 15 percent discount

For this problem, we're finding the percent of 300. To do that we:

1. Multiply 300 by 15.

300 x 15 = 4500

2. Divide 4500 by 100. (% = 100)

4500 / 100 = 45

Therefore, the unit price is 45. But we're not done. We need to subtract 45 by 300.

300 - 45 = 255

Now, our answer is 255 and the unit price is 45.

Al, Bert, and Rob determined that the sum of their ages is 62. Bert is twice as old as Rob, who is 10 years older than Al. How old is each?

Answers

Answer: AI is 8, Rob is 18, and Bert is 36

Step-by-step explanation:

Ok, so the sum of their age is 62. Bert is x2 of Rob. Also someone is 10 years older than AI, lets assume Rob is the guy that is 10 years older. x+y+10+(z times 2)=62. So lets solve it. 62-10=52. 52=x+y+(z times 2). Now if you think about it x and y is the same, because the 10 is already minused. So it's now x*2+z*2=52, if you assume it now, z is x+10. So now it is 52=x*2+(x+10)x2. Now we break out the brackets so its x*2+x*2+20=52. Lets simplify it. x*4+20=52, lets swift the 20 the the other side. x*4=52-20, x*4=32. 32/4=8 so 8 is x. Now we know AI is 8, Rob is 18, and Bert is 36!

Patrick is riding his bike on a rectangular path around his city. There is a rest area at each of the path's four corners. The city map shows the corners marked with coordinates of (–2, 2), (1, 2), (1, –2), and (–2, –2). Each unit represents 2.5 miles.

Answers

Question:

What is the perimeter of the path, in miles?

Answer:

35 miles

Step-by-step explanation:

Given

Let the corners be ABCD

[tex]A = (-2,2)[/tex]

[tex]B = (1,2)[/tex]

[tex]C = (1,-2)[/tex]

[tex]D = (-2,-2)[/tex]

First, we calculate the perimeter of the corners in units.

This is done by calculating the distance between the corners.

Distance is calculated as:

[tex]D = \sqrt{(x_2 - x_1)^2 +(y_2 - y_1)^2 }[/tex]

For AB:

[tex](x_1,y_1) = (-2,2)[/tex]

[tex](x_2,y_2) = (1,2)[/tex]

[tex]D_1 = \sqrt{(1 - (-2))^2 +(2 - 2)^2 }[/tex]

[tex]D_1 = \sqrt{(1 +2)^2 +(0)^2 }[/tex]

[tex]D_1 = \sqrt{3^2}[/tex]

[tex]D_1 = 3[/tex]

For BC

[tex](x_1,y_1) = (1,2)[/tex]

[tex](x_2,y_2) = (1,-2)[/tex]

[tex]D_2 = \sqrt{(1 - 1)^2 +(-2 - 2)^2 }[/tex]

[tex]D_2 = \sqrt{(0)^2 +(-4)^2 }[/tex]

[tex]D_2 = \sqrt{16 }[/tex]

[tex]D_2 = 4[/tex]

For CD:

[tex](x_1,y_1) = (1,-2)[/tex]

[tex](x_2,y_2) = (-2,-2)[/tex]

[tex]D_3 = \sqrt{(-2 - 1)^2 +(-2 - (-2))^2 }[/tex]

[tex]D_3 = \sqrt{(-3)^2 +(-2 +2)^2 }[/tex]

[tex]D_3 = \sqrt{9 +0^2 }[/tex]

[tex]D_3 = \sqrt{9 }[/tex]

[tex]D_3 = 3[/tex]

For DA

[tex](x_1,y_1) = (-2,-2)[/tex]

[tex](x_2,y_2) = (-2,2)[/tex]

[tex]D_4 = \sqrt{(-2 - (-2))^2 +(2 - (-2))^2 }[/tex]

[tex]D_4 = \sqrt{(-2 +2)^2 +(2 +2))^2 }[/tex]

[tex]D_4 = \sqrt{0^2 +4^2 }[/tex]

[tex]D_4 = \sqrt{4^2 }[/tex]

[tex]D_4 = 4[/tex]

The perimeter P in units is:

[tex]P = D_1 + D_2 + D_3 + D_4[/tex]

[tex]P = 3+4+3+4[/tex]

[tex]P = 14[/tex]

Given that:

[tex]1\ units = 2.5\ miles[/tex]

Multiply both sides by 14

[tex]14 * 1\ units = 14 * 2.5\ miles[/tex]

[tex]14 \ units = 35\ miles[/tex]

Hence, the perimeter is 35 miles

Find the dimensions of the square.

Area = 441 cm²

Answers

Answer:

21 cm by 21 cm

Step-by-step explanation:

The formula for the area of a square is A = x^2, where x is the length of any one side of the square.  Here,

441 cm² = x²

This actually has two roots:  {√441, -√441), but since x must be positive here, to be a dimension of the square, we choose +√441, or +21.

The dimensions of the square are 21 cm by 21 cm.

Answers

Answer:

a) 4/15

b) 900 bolígrafos azules

750 bolígrafos negros

600 bolígrafos rojos

Step-by-step explanation:

Una fábrica de bolígrafos fabrica sus propios productos en tres colores diferentes. 2/5 de su fabricación son bolígrafos azules, 1/3 son bolígrafos negros y el resto son bolígrafos rojos.

a) ¿Qué fracción de bolígrafos son bolígrafos rojos?

Deje que el número total de bolígrafos se represente como 1

La fracción de bolígrafos rojos =

1 - (Fracción de bolígrafos azules + Fracción de bolígrafos negros)

= 1 - (2/5 + 1/3)

El mínimo común denominador es 15

= 1 - (6 + 5/15)

= 1 - 15/11

= 4/15

Por lo tanto, la fracción de bolígrafos rojos = 4/15

b) Si se han fabricado un total de 2250 bolígrafos en un día, ¿cuántos se han fabricado de cada color?

Para bolígrafos azules

2/5 de su fabricación son bolígrafos azules,

= 2/5 × 2250 bolígrafos

= 900 bolígrafos azules

Para bolígrafos negros

1/3 son bolígrafos negros

= 1/3 × 2250 bolígrafos

= 750 bolígrafos negros

Para bolígrafos rojos

4/15 son bolígrafos rojos

= 4/15 × 2250 bolígrafos

= 600 bolígrafos rojos
