The general form for a pair of linear equations in two variables x and y is
and

----- (1)
----- (2)
Comparing equations 1 and 2 with the general form of equation to write their co-efficient,

Compare the ratio,

If , then the pair of linear equations has exactly one solution.
So, it said to be consistent.

A rectangular container that has a length of 30 cm, a width of 20 cm, and a height of 24 cm is filled with water to a depth of 1

BaLLatris [955]

Answer:

$5400cm^{3}$ more water could be added to the container before the container overflows

Step-by-step explanation:

The volume of the rectangular container is got by multiplying its given dimensions: Length X breadth X height

This will be 30 X 20 X 24 = $14400 cm^{3}$

To find the volume of water inside the rectangular container, we will use the new height for our computation of volumes, keeping the length and breadth of the cylinder the same.

This will be $30 \times 20 \times 15 =9000 cm^{3}$

The volume of water needed to be added until the container overflows will be got by subtracting the volume of water present in the container from the total volume of the container

$14400 - 9000 =5400cm^{3}$

Note 1 $cm^{3}= 1 ml$

a vertical pedestal stands on the ground and is surmounted by a vertical flag staff of height 5 m.At a point on the ground the a

Scilla [17]

Answer:

2.5 ft

Step-by-step explanation:

The figure for the given scenario is shown below.

There are two right angled triangles, ΔACD and ΔBCD

The height of flag staff is represented by segment AB, BC is the height of pedestal stand , D is a point on the ground that makes angles 30° and 60° with the bottom and top of staff at B and A respectively.

AB = 5 ft. Let the height of pedestal stand be $x$ ft and the distance of point D from the bottom of stand be $y$ ft as shown in the figure.
