If six is placed at the end of a two digit number the result is 294 greater than the number, what was the number?

solmaris [256]

If 6 is placed at the right end of AB, so the number is AB6.
the value of the three-digit number formed is 294 more than AB, means that if AB6 - 294 = AB <span>

</span>AB 6
- 2 9 4
AB <span>

</span>6 - 4 = B = 2 <span>

</span>If B = 2, then the tens digit is 2 - 9 (which can't be) so 12 - 9 = 3 = A <span>

</span>A = 3, and B = 2 <span>

</span><span>check: 326 - 294 = 32</span>

Find the point of intersection (if any) of the following pairs of lines: a) x – 2y +1=0 2x + 3y – 7 = 0 b) x-2y+11=0 -x+2y-13 =

pychu [463]

Answer:

a) (11/7, 9/7)

b) There's no point of intersection

Step-by-step explanation:

a) x - 2y + 1 = 0

2x + 3y - 7 = 0

To find the point of intersection, we need to solve the system of equations and the result will be the point of intersection (x,y)

$x-2y+1=0\\x= 2y-1$

Now we substitute x in the second equation:

$2x+3y-7=0\\2(2y-1)+3y-7=0\\4y-2+3y-7=0\\7y-9=0\\y=9/7$

Now we substitute y in our first equation.

$x-2y+1=0\\x-2(9/7)+1=0\\x-18/7+1=0\\x=18/7-1\\x=11/7$ .

The point of intersection is (11/7, 9/7)

b) x -2y +11 =0

-x + 2y - 13 =0

We are going to follow the same procedure:

$x-2y+11=0\\x=2y-11$

$-(2y-11)+2y-13=0\\-2y+11+2y-13=0\\0y=2\\0=2$

Since this system of equations doesn't have a solution, the system has no point of intersection.

You are skiing down a mountain with a vertical height of 800 feet. The distance from the top of the mountain to the base is 1600

adoni [48]

Answer:

θ = $30^{0}$

Step-by-step explanation:

Since the vertical height of the mountain is 800 feet, and the distance from the top to its base is 1600 feet. Let the angle of elevation be represented by θ, applying the required trigonometric function;

Sin θ = $\frac{opposite}{hypotenuse}$

Sin θ = $\frac{800}{1600}$

= 0.5

θ = $Sin^{-1}$ 0.5

θ = $30^{0}$

Thus, the angle of elevation from the base to the top of the mountain is $30^{0}$ .
