There must be 2 lines on every plane because you need a y-axis and an x-axis.
Answer:
25 ft
Step-by-step explanation:
The 2 triangles are similar hence the ratios of corresponding sides are equal, that is
=
= 5
multiply both sides by 5
x = 5 × 5 = 25
The height of the tree is 25 ft
Answer:
See the diagram for understanding
Step-by-step explanation:
Suppose the woman at point A and moves towards east . But the point A is at the south and she is moving upwards towards east according to the compass. That is why this statement is incorrect .
In the compass it would be east but she has to move north to reach east. There's a difference between the actual position the direction of movement of the person to reach that position.
This is better explained by the following diagram.
Now we can see she will move along line B , C and D to reach east which are actually to the north of her position. So the given statement is false.
Answer:
Number of sand bags needed = 124
Step-by-step explanation:
Diameter of garden = 40 yd
Width of path = 6 yd
Diameter of garden with path = 40 + 2 x 6 = 52 yd
We need to find area of path.
Area of path = Area of garden with path - area of garden

Area covered by one sand bag = 7 yd²

Number of sand bags needed = 124
Answer:
Step-by-step explanation:
x + y = 25 ...........................(1)
{4x + 2y =64} / 2 divide the equation by 2
2x + y = 32 ........................(3)
Step Two
subtract (1) from (3)
2x + y = 32
x + y = 25
x = 7
Therefore from equation 1 we get x + y = 25
but x = 7
7 + y = 25 Subtract 7 from both sides.
y = 25 - 7
y = 18
Check
4*x + 2*y = 64
4*7 + 2*18 =? 64
28 + 36 = ? 64
64 = 64
The checks out to be the right answer.
