Answer:

The house is 2000 meters from the school.

Step-by-step explanation:

Given that, when I have walked 20% of the way to school, I have 1200 meters more to walk than when I have 20% of the walk remaining, to determine how far, in meters, is it from my home to my school the following calculation has to be done:

100 - 20 = 80

80 = 20 + 1200

80 - 20 = 1200

60 = 1200

1200/60 = 20

20 x 100 = 2000

Therefore, the house is 2000 meters from the school.

Answer:

x=30

y=70

z=80

step by step explanation:

Answer:

60

Step-by-step explanation:

All triangles have a total measurement of 180 degrees. So to find the last angle measure subtract 90 and 30 from 180, 180-(90+30). This equals 60 degrees. Additionally, a triangle with a 90 and 30 degree angle is known as a 30-60-90 special right triangle. All of these triangles will have 60 as their third measurement.

Answer:

Number of year in which population will be 180,000 = 6 year (Approx.)

Step-by-step explanation:

Given:

Population in 2007 = 168,979

Rate of increase in population = 1% = 0.01

Future population = 180,000

Find:

Number of year in which population will be 180,000

Computation:

A = P[1+r]ⁿ

Future population = Population in 2007[1+Rate of increase in population]ⁿ

180,000 = 168,979[1+0.01]ⁿ

180,000 = 168,979[1.01]ⁿ

1.06522 = [1.01]ⁿ

n = 6 (Approx.)

Number of year in which population will be 180,000 = 6 year (Approx.)

Answer:

5/2, 2.6, 1 + sqrt(3), sqrt(8)

Step-by-step explanation:

Use a calculator:

sqrt(8) = 2.83

5/2 = 2.5

2.6 = 2.6

1 + sqrt(3) = 2.73

Answer:

5/2, 2.6, 1 + sqrt(3), sqrt(8)

Answer:

14.94

Step by step:

 25/30 = 83.333

.30x83 = 24.9

.60 x 24.9 = 14.94

Answer:

50

Step-by-step explanation:

Let's set the number as "x". So, 30% of x is 25. We can then write this equation.

30% * x = 25

Change 30% to a decimal

0.3 * x = 25

Divide both sides by 0.3

x = 83 and 1/3

Then, to find 60% of this number, write this equation.

60% * 83 1/3 =

0.6 * 83 1/3 =

50

Step-by-step explanation:

Formula

(99°C × 9/5) + 32 = 210.2°F

Answer:

12.5

Step-by-step explanation:

y= 2/3x+4 and y=2/3x-1 1 are parallel: slope 1 = 2/3 = slope 2

the distance of line 1 and line 2 is the segment length of perpendicular line intercept two parallel lines. In other words, the distance between two parallel lines in the plane is the minimum distance between any two points lying on the lines. It equals the perpendicular distance from any point on one line to the other line.

equation of the perpendicular line pass the y intercept of line 1: y=2/3x+4  (0,4) is y = -3/2x + 4, which intercept with line 1 at (0,4)

solve the intercept of perpendicular line with line 2: get (6.9 , -6.4)

    y=-3/2x + 4 and y=2/3x-1 1 (you should be able to solve this part by self)

distance of (0,4) and (6.9,-6.4): √(6.9-0)²+(-6.4-4)² = √155.77 = 12.48 ≈ 12.5

12 percent

Step-by-step explanation:

well because if you divide 840 by 36 you get 23.33 if you divide 840 by 3 its 280, if you divide that by 23.33 you get 12 percent.

Answer:

El punto es (3, 1)

Step-by-step explanation:

Sabemos que la ecuación de un circulo centrado en el punto (a, b), con radio R, se escribe como:

(x - a)^2 + (y - b)^2 = R^2

En este caso, sabemos que el diametro de nuestro circulo es igual al segmento que uno los puntos A(2, 3) y B(4, -1) (y el diametro es el doble del radio)

Entonces el centro del punto es exactamente el punto medio en el segmento dado.

Para encontrar el punto medio en el segmento dado, tenemos que encontrar el punto medio entre los valors en x, y el punto medio entre los valores en y.

Donde el punto medio entre dos valores a y b se calcula como:

punto medio = (a + b)/2  

El punto medio en x es:

x = (2 + 4)/2 = 3

El punto medio en y es:

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

Entonces el punto medio en el segmento es:

C(x, y) = C(3, 1)

Esto quiere decir que el centro de la circunferencia va a ser el punto (3, 1)

Answer:

17

Step-by-step explanation:

Create a system of equations where t is the number of t shirts he sold, and s is the number of sweatshirts he sold

t + s = 28

12t + 20s = 424

Solve by elimination by multiplying the top equation by -20, then adding them together

-20t - 20s = -560

12t + 20s = 424

-8t = -136

Solve for t:

t = 17

So, Colton sold 17 t shirts

Answer:

Solution: 36x2−9

Step-by-step explanation:

So, you always have to start with distrubuting which is basically dividing.

Heres the equation that I started with. You can do it differently of course.

36x2+18x-3(6x+3)

combine like terms.

36x2-9

, your solution will be

36x2-9

Answer:

n = 9

Step-by-step explanation:

Here we have the table:

X     Y

4     3

6    5

7     6

10   n

First, we want to find the rule.

in the first pair we have:

x = 4

y = 3

We can see that the y-value is one smaller than the x-value

y = 3 = 4 - 1 = x - 1

For the second pair we have:

x = 6, y = 5

We again can see that the y-value is one smaller than the x-value

y = 5 = 6 - 1 = x - 1

For the third pair we have:

x = 7, y = 6

Again, can see that the y-value is one smaller than the x-value.

y = 6 = 7 - 1 = x - 1

We can conclude that the rule is:

y = x - 1

For the last pair, we have:

x = 10, y = n

Then:

n = 10 - 1 = 9

n = 9

Then the table is:

X     Y

4     3

6    5

7     6

10   9

Answer:

one real solution being only -1

Step-by-step explanation:

Solve for w over the real numbers:

4 w^2 + 8 w + 4 = 0

Divide both sides by 4:

w^2 + 2 w + 1 = 0

Write the left hand side as a square:

(w + 1)^2 = 0

Take the square root of both sides:

w + 1 = 0

Subtract 1 from both sides:

Answer: |

| w = -1

[tex]Discriminant=0\\b)\ One\ Real\ Solution[/tex]

Step-by-step explanation:

[tex]We\ are\ given\ that:\\4w^2+8w+4=0\\We\ know\ every\ quadratic\ equation\ can\ be\ represented\ in\ the\ form\ of:\\ax^2+bx+c=0,\ where\ x \neq 0\\Hence,\\Lets\ first\ recognize\ the\ co-efficients\ of\ the\ algebraic\ terms( x^2,\ x,\ x^0),\\ which\ are\ a,b\ and\ c\ respectively.[/tex]

[tex]Hence,\\4w^2+8w+4=0\\4(w^2)+8(w)+4(w^0)=0\\Hence,\\a=4,\ b=8,\ and\ c=4.[/tex]

Answer:

Trinomial.

Step-by-step explanation:

A monomial has one term. A binomial has two terms. A trinomial has 3 terms.

x + y + z has 3 terms; x, y, z. So it is considered a trinomial.
