Answer:

see explanation

Step-by-step explanation:

Sum the 3 consecutive integers and equate to 36

x + x + 2 + x + 4 = 36

3x + 6 = 36 ( subtract 6 from both sides )

3x = 30 ( divide both sides by 3 )

x = 10

The 3 consecutive integers are

10, 10 + 2, 10 + 4, that is

10, 12, 14

Please hurry I will mark you brainliest <br> Find the surface area
erastova [34]

Triangle area = 8 x 3/2

= 12

12 x 2 = 24cm^2 for 2 triangles

Height of rectangle must be found, so use pythag on triangle

a^2+ b^2 = c^2

16 + 9 =c^2

C=5

A= 5 x 12

= 60

60 x 3 triangles in total is 180cm^2

180cm^2 + 24cm^2 = 204cm^2

Ans: 204cm^2

Please help with this question, I need the help urgently
grin007 [14]

Answer:

P in terms of V is:

P = 432/V

Step-by-step explanation:

We know that y varies inversely as x, we get the equation

y ∝ 1/x

y = k/x

k = yx

where k is called the constant of proportionality.

In our case,

P is inversely proportional to V

Given

P = 18

V = 24

so

P = k/V

k = PV

substituting P = 18 and V = 24 to determine k

k = 18 × 24

k = 432

now substituting k = 432 in P = k/V

P =  432/V

Therefore, P in terms of V is:

P = 432/V

Find an equation of the circle that satisfies the given conditions. (Use the variables x and y.)
prohojiy [21]

Answer:

x^2 + y^2 = 52

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, (x_1,y_1) and (x_2,y_2). The distance between them is given by:

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

Equation of a circle:

The equation of a circle with center (x_0,y_0) and radius r has the following format:

(x - x_0)^2 + (y - y_0)^2 = r^2

Center at the origin;

This means that x_0 = 0, y_0 = 0

So

(x - x_0)^2 + (y - y_0)^2 = r^2

(x - 0)^2 + (y - 0)^2 = r^2

x^2 + y^2 = r^2

Passes through (4, 6)

The radius is the distance from this point to the center. So

r = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

r = \sqrt{(4-0)^2+(6-0)^2}

r = \sqrt{16+36}

r = \sqrt{52}

So

r^2 = 52

Then

x^2 + y^2 = r^2

x^2 + y^2 = 52
