Answer: John is now 18 years old

Step-by-step explanation:

Let, John's age is now x years.

5 years ago, he was (x - 5) years old

In 8 years, he will be (x + 8) years old

By the given condition,

x - 5 = 1/2 (x + 8)

⇒ 2 (x - 5) = x + 8

⇒ 2x - 10 = x + 8

⇒ 2x - x = 8 + 10

⇒ x = 18

Answer:

69.4 inches

Step-by-step explanation:

A kite is a quadrilateral (has four sides and four angles) with two pairs of congruent adjacent sides. The diagonals of a kite are perpendicular to each other.

To prove that quadrilateral ADBC is a kite, the diagonals of the kite have to be perpendicular to each other.

AD ⊥ BC.

Since adjacent sides are equal to each other, hence:

BC = BD, AC = AD

The coordinate of the vertices are A(11, 0), B(11, 26), C(0, 18) and D(22, 18)

[tex]BC=\sqrt{(0-11)^2+(18-26)^2} =13.6\ unit\\\\AC=\sqrt{(0-11)^2+(18-0)^2} =21.1\ unit[/tex]

BC = BD, AC = AD

Perimeter of kite = BC + BD + AC + AD = 2BC + 2AC = 2(13.6) + 2(21.1) = 69.4 units = 69.4 inches

Answer:

$0.09/minute

Step-by-step explanation:

$45/8 hours is $5.63 per hour

There is 60 minutes in an hour.

So you do $5.63/60 minutes and it's about $0.09

So it's 9 cents per minute

Answer:

15 = 2x - 3y

Step-by-step explanation:

We have the two points P1(3,-3) and P2(9,1).

First, calculate the slope between those points:

slope [tex]= \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - (-3)}{9 - 3} = \frac{4}{6} = \frac{2}{3}[/tex]

Now simply move 3 steps from (3,-3) towards the y-axis to get the intersection with the y-axis (each step reduces x by 1 and applies the slope to the y-value):

(3,-3)

---> (2, -3 - (2/3)) = (2,-3 2/3)

---> (1, (-3 2/3) - 2/3) = (1, -4 1/3)

---> (0, (-4 1/3) - 2/3) = (0,-5)

This tells us, that our line intersects the y-axis at (0,-5).

The general form of a line is f(x) = <SLOPE> * x + <Y-VALUEATXEQUALSZERO>.

In our case: f(x) = y = (2/3)x -5.

To get it into the correct form, we simply subtract y from both sides and get:

0 = (2/3)x - y - 5

To get only integers just multiply everything with 3 and add 15 and get:

15 = 2x - 3y, which fulfils the form asked for in the problem.

Answer:

x=4

Step-by-step explanation:

6(x+8)-30+7=49

6x+48-30+7=49

6x=49-48+30-7

6x=1+23

6x=24

x=[tex]\frac{24}{6}[/tex]

x=4

Step-by-step explanation:

Para resolver esto yo use una app llamada m a t h w a y

(sin los espacios) esta puede estar en varios idiomas, aunque esto se modifica segun el idioma en donde la uses.

6(x+8) -30+7 = 49                           1. Simplifica 6(x+8) -30+7

6x+25 = 49                                     2. Mueve todos los términos que no

                                                   contengan x al lado derecho de la ecuación

6x = 24                                           (25 pasa restando por lo cual sería, 49-25

                                                       que es igual a 24.)

                                                       3. Divide cada término por 6 y simplifica.

x = 4

Espero esto haya ayudado!

Step-by-step explanation:

[tex]slope = \frac{rise}{run} = \frac{y2 - y1}{x2 - x1} \\ = \frac{ - 7 - 13}{5 - ( - 3)} \\ = \frac{ - 20}{8} \\ = \frac{ - 2 \times 10}{2 \times 4} \\ = \frac{ - 10}{4} \\ = \frac{ - 2 \times 5}{ 2 \times 2} = \frac{5}{2} [/tex]

Answer:

Mean = 3.5

Median = 3.5

Mode = 5, 2

Step-by-step explanation:

Hope that helps!

Mean: To find the mean, simply add the numbers together and divide by the amount of numbers in the set:

Mean: (5 + 2 + 5 + 2)/4

= (14)/4

= 3.5

Mean = 3.5

Median: To find the median, simply order from least to greatest, and find the middle number in the set. That is your median. In the case of an even amount of numbers in the set, find the mean with the two median numbers (as in this case):

Median: (2 + 5)/2

= 7/2

= 3.5

Median: 3.5

Mode: The Mode is the number that shows up the most frequently. As both given numbers show up the same amount of times (twice), there is no mode.

Mode: None.

Range: The Range is found by subtracting the greatest number with the least number:

5 - 2 = 3

Range: 3

Answer:

329.91 cm^2

Step-by-step explanation:

A ring-shaped region is shown below. Its inner radius is 8m, and its outer radius is 11m. 8m 11m Find the area of the shaded region. Use 3.14 for π. Do not round your answer.

Your answer

Given data

inner radius= 8cm

area= πr^2

area= 3.142*8^2

area= 3.142*16

area= 50.272 cm^2

outer radius= 11cm

area= πr^2

area= 3.142*11^2

area= 3.142*121

area= 380.182 cm^2

Hence the area of the shaded part is

=380.182-50.272

=329.91 cm^2

Answer: Alex Drake and the plot twist is when "A.D." reveals themselves to be Alex Drake, the twin sister of Spencer.

Answer:

width = 3

length = 4

Step-by-step explanation:

Ok so you can form a system of equations where w is the width and l is the length:

3l + 4w = 24

2l - 3w = -1

you want to eliminate one of the variables and then solve, so you can first take the top equation and multiply both sides by 2:

6l + 8w = 48

next, multiply the second equation by 3:

6l - 9w = -3

now that both include 6l, you can subtract the two equations

6l + 8w = 48

- (6l - 9w = -3)

17w = 51

divide both sides by 17

w = 3

Plug w = 3 into the equation 3l + 4w = 24:

3l + 4 * 3 = 24

3l + 12 = 24

subtract 12 from both sides

3l = 12

divide both sides by 3

l = 4
