determine whether y varies directly with x. if so, find the constant k and write the equation x =6,18,54,162 y= 24,72,216,648

Answer:

see explanation

Step-by-step explanation:

6 × 24 ← replace 24 by 4 + 20

= 6(4 + 20) ← multiply each term in the parenthesis by 6

= 24 + 120

= 124

Answer:

70 pi cm

219.80 cm

219.9114858 cm

Step-by-step explanation:

The circumference of a circle is given by

C = pi*d

C = pi * 70cm

Using 3.14 for pi

C = 219.80cm

Using the pi button

219.9114858cm

Circumference of circle = 2πr

Hence , r is 35 cm

⇛Circumference of circle = 2πr

⇛Circumference of circle = 2*3.14*35

⇛Circumference of circle = 6.28*35

⇛Circumference of circle = 219.8 cm

Hence , Circumference of circle is 219.8 cm

Answer:

hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

Answer:

no we cannot add them, though we can multiply or divide them. You cannot add them because they have different variables, we need the same variables to add or subtract those.

Answer:

m = 65

Step-by-step explanation:

Given

- 13 = [tex]\frac{m}{-5}[/tex] ( multiply both sides by - 5 )

65 = m

Answer:

d ≈ 9.5

Step-by-step explanation:

Calculate the distance using the distance formula

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

with (x₁, y₁ ) = (8, 2) and (x₂, y₂ ) = (- 1, 5)

d = [tex]\sqrt{(-1-8)^2+(5-2)^2}[/tex]

   = [tex]\sqrt{(-9)^2+3^2}[/tex]

   = [tex]\sqrt{81+9}[/tex]

    = [tex]\sqrt{90}[/tex]

    ≈ 9.5 ( to the nearest tenth )

Step-by-step explanation:

Answer:

y = 3x - 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - [tex]\frac{1}{3}[/tex] x - 4 ← is in slope- intercept form

with slope m = - [tex]\frac{1}{3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{3} }[/tex] = 3 , then

y = 3x + c ← is the partial equation

To find c substitute (3, - 1 ) into the partial equation

- 1 = 9 + c ⇒ c = - 1 - 9 = - 10

y = 3x - 10 ← equation of perpendicular line

Answer:

50 Percent of 320 is 160. 30 divided by 5, is 15, meaning that 300 divided by 5 will be 150. Divide 20 in half, and you get 10. Your answer is 150+10=160

Answer:

y= -6/5x +3

Step-by-step explanation:

y = mx + b is the formula for every linear equation. m is the slope (comment if you don't know how to find the slope), and b is the y-intercept. You just have to find those terms and plug them in.

Hi,

Answer is $0.19

Step-by-step explanation:-

We know that:-

15 dimes = $1.50

20 nickels = $1.00

8 quarters = $2.00

half dollar = $0.50

19 pennies = $0.19

Total = $5.19

Since Billy spended $5, so,

$5.19 - $5 = $0.19

Hope it helps you...

Answer:

First take 0.23 as 0.23/1

Then Multiply the numerator and denominator by any number, Let us say 100

So it becomes,

0.23 x 100/100

=> 23/100

Part A : D.)

Part B : Length of the sandbox is 10 feet.

Step-by-step explanation:

Given,

Perimeter = 29 ft

We need to find the equation for the perimeter and also the length of the sandbox.

Solution,

Let the width of the sandbox be 'w'.

Now as per question said;

The length of the sandbox is 1 foot longer than twice the width of the sandbox.

So we can say that;

Length =

Now we know that the perimeter is equal to the sum of twice of length and width.

framing in equation form, we get;

Perimeter =

we have given the perimeter, so on substituting the value, we get;

Hence The equation used to find the width is  .

Now we solve for 'w'.

Applying distributive property, we get;

Subtracting both side by '2' we get

Dividing both side by 6 we get;

Width of the sandbox = 4.5 ft

Length of the sandbox =

Hence Length of the sandbox is 10 feet.

Answer:

35 Degrees

Step-by-step explanation:

Angle JKL is reffering to the whole angle. The angle is split into two, it gives us the measurement for angle 1 which is 38 degrees. To find the answer we simply subtract angle m from angle JKL. 73-38 = 35... So angle 2 is 35 degrees.

Answer:

x = 21

Step-by-step explanation:

72+46+(2x+20)=180

118+20+2x=180

138+2x=180

138-138+2x=180-138

2x=42

2x/2=42/2

x=21
