Answer:

35x + 60y = 690

Why:

We need to correct number to represent X (which is 35) and Y (which is 60).

And 35x + 60y = 690, 690 being the total, fits what we need to answer.

All of the other options display an incorrect number for the X and Y values.

A house is built on coordinates (2,9). There is a water pipeline that runs along the line y = 2 3 x – 1. What is the approximate

Basile [38]

Answer:

7.21 units

Step-by-step explanation:

The shortest length needed to connect the house to the existing pipeline is the perpendicular distance between the location of the house (2,9) and the line y = 2/3x - 1.

The perpendicular distance (d) between a point ( $x_1,y_1$ ) and the line Ax + By + C = 0 is given as:

$d=\frac{|Ax_1+By_1+C|}{\sqrt{A^2+B^2} }$

The line is given by y = 2/3 x - 1; 2/3x - y - 1 = 0. The point = (2, 9)

hence A = 2/3, B = -1, C = -1, $x_1=2,y_1=9\\$ . Therefore:

$d=\frac{|\frac{2}{3}(2)+(-1)(9)+(-1) |}{\sqrt{\frac{2}{3}^2+(-1)^2 } } \\\\d=7.21$

How do you find the area of this triangle.

Kazeer [188]

Answer:

Step-by-step explanation:

To find the area of any right triangle, meaning a triangle with a right angle, you use 1/2 base x height

So... here the base is 9 and the height is 10

Therefore: 1/2 x (9) x (10)

1/2 x 90

= 45
