The sum of two numbers is 36 . one number is 3 times as large as the other. what are the numbers?

1 answer:

8 0

X= one number
3x= the other number

Add the two numbers together.

x + 3x= 36
4x= 36
x= 9

Other Number
=3x
=3(9)
=27

ANSWER: The numbers are 9 and 27.

Hope this helps! :)

Find the missing side

Marrrta [24]

Answer:

x = 71.5 in

Step-by-step explanation:

Remember the SOHCAHTOA rule

Soh...

Sine = Opposite / Hypotenuse

...cah...

Cosine = Adjacent / Hypotenuse

...toa

Tangent = Opposite / Adjacent

In this case, we use: CAH.

cos(52) = 44/x

x = 44/cos(52)

x = 71.5 inches

Decide whether the pair of lines is parallel, perpendicular, or neither.

maw [93]

The lines are: B) Perpendicular

Step-by-step explanation:

we have to convert both lines in slope-intercept form to find slopes

So,

$3x - 6y = -13\\-6y = -3x-13\\\frac{-6y}{-6} = \frac{-3x-13}{-6}\\\frac{-6y}{-6} = \frac{-3x}{-6}+\frac{-13}{-6}\\y = \frac{1}{2} +\frac{13}{6}$

Let m1 be the slope of first line

$m_1 = \frac{1}{2}$

For the second line:

$18x + 9y = 5\\9y = -18x+5\\\frac{9y}{9} = \frac{-18x+5}{9}\\\frac{9y}{9} = \frac{-18}{9}x+\frac{5}{9}\\y = -2x+\frac{5}{9}$

Let m2 be the slope of line 2

So,

If the lines are parallel, their slopes are equal

If the lines are perpendicular, product of their slopes is -1

We can see that

$\frac{1}{2} * -2 = -1$

Hence,

The lines are: B) Perpendicular

What is an equation of the line that passes through the points 0,-2and 0,-5

kherson [118]

Answer:

Any equation with a slope of 3 will work. You can use any y-intercept. This equation will work: y = 3x+1

Step-by-step-explanation:

3x says that the slope is 3, and on a coordinate plane, 2 is 3 places above 5, and since the slope is 3, it will go 3 spots up, and run into (0,2)
