Answer:

x=3y

Step-by-step explanation:

ATQ

(x+y):(x-y)=2

or, x+y=2x-2y (crossmultiply)

or, 0= 2x-x-2y-y

or, x- 3y=0

or, x=3y is required equation

Answer: 24.2° SouthWest

Step-by-step explanation:

First step: DRAW A PICTURE of the vectors from head to tail (see image)

I created a perpendicular from the resultant vector to the vertex of the given vectors so I could use Pythagorean Theorem to find the length of the perpendicular. Then I used that value to find the angle of the plane.

Perpendicular (x):

cos 35° = adjacent/hypotenuse

cos 35° = x/160

→ x = 160 cos 35°

Angle (θ):

sin θ = opposite/hypotenuse

sin θ = x/320

sin θ = 160 cos 35°/320

θ = arcsin (160 cos 35°/320)

θ = 24.2°

Direction is down (south) and left (west)

A sign painter paints individual numerals for a row of 50 houses. The houses are numbered with consecutive integers from 1 to 50

Iteru [2.4K]

Answer: 5

List out the numbers from 1 to 50. Then go through that list and circle any numbers that have 9 in them. Those numbers are:
9, 19, 29, 39, 49
So there are 5 houses with 9s painted
