Answer:

x = 36, y = 54.

Step-by-step explanation:

So if x = 36 and y = ?,

Its the same as x = 12, and y = 18.

36 / 12 = 3

That means y / 18 = 3.

Lets reverse this and make it a multiplication problem.

18 x 3 = y.

18 x 3 = 54.

So if x = 36, y = 54.

I really need help with the question above! This is my second time asking. Am I right? If not please give me the correct answer

Hey there! :D

Pay attention to the given angles.

We know that a circle is equal to 360 degrees.

We know two angles, and the other 2 are the same measure.

170+44= 214

Subtract that from 360, since that is what the circle equals.

360-214= 146

Divide that by two, since there are 2 equal angles left.

146/2= 73

<DOB= 73 degrees.

You were correct, so good work!

I hope this helps!

Answer:

WX = 33

(x, y) = (2, 10)

Step-by-step explanation:

The hash marks tell you WX is a midline, so has the measure of the average of the two bases.

WX = (PQ +SR)/2 = (27 +39)/2 = 66/2

WX = 33

The hash marks also tell you ...

PW = WS

y +4x = 18 . . . . . . substitute the given expressions

and also

QX = XR

2y +x = 22 . . . . . substitute the given expressions

If you solve the first equation for y, you get ...

y = 18 -4x

Substituting that into the second equation gives ...

2(18-4x) +x = 22

36 -7x = 22 . . . . . . . simplify

14 = 7x . . . . . . . . . . . add 7x-22 to both sides

2 = x . . . . . . . . . . . . divide by 7

y = 18 -4(2) = 10 . . . find y using the above relation

The values of x and y are 2 and 10, respectively.

My favorite "quick and dirty" way to solve a set of linear equations is using a graphing calculator. It works well for integer solutions.

Find the shortest distance, d, from the point (5, 0, −6) to the plane x + y + z = 6.

DENIUS [597]

Answer:

$\frac{7}{\sqrt{3}}$

Step-by-step explanation:

The shortest distance d, of a point (a, b, c) from a plane mx + ny + tz = r is given by:

$d = |\frac{(ma + nb + tc - r)}{\sqrt{m^2 + n^2 + t^2}} |$ --------------------(i)

From the question,

the point is (5, 0, -6)

the plane is x + y + z = 6

Therefore,

a = 5

b = 0

c = -6

m = 1

n = 1

t = 1

r = 6

Substitute these values into equation (i) as follows;

$d = |\frac{((1*5) + (1*0) + (1 * (-6)) - 6)}{\sqrt{1^2 + 1^2 + 1^2}} |$

$d = |\frac{((5) + (0) + (-6) - 6)}{\sqrt{1 + 1 + 1}} |$

$d = |\frac{(-7)}{\sqrt{3}} |$

$d = \frac{7}{\sqrt{3}}$

Therefore, the shortest distance from the point to the plane is $d = \frac{7}{\sqrt{3}}$

Your Assignment What is the fractional equivalent of the repeating decimal n = 0.1515... ? Answer the questions to find out.

Savatey [412]

Answer:

The fractional equivalent of the repeating decimal would be 15/99 and 0.1515... is a repeating decimal so it doesn't end, but in the shown number is 4 digits.
