Answer:

The number line goes from negative two to two.

The numbers shown by the number line (-2, -1, 0, 1 and 2) are all integers.

Between each pair of numbers, there are 4 equal segments, each one of 1/4 = 0.25 units length. Therefore we can locate, for example, 1.25, 0.5 and -0.75 at the number line.

Solve the following system using the elimination method: 2x-4y=2 -4x+6y=-4

Tomtit [17]

Answer:

(1, 0)

Step-by-step explanation:

Given the 2 equations

2x - 4y = 2 → (1)

- 4x + 6y = - 4 → (2)

Multiplying (1) by 2 and adding to (2) will eliminate the x- term

4x - 8y = 4 → (3)

Add (2) and (3) term by term

(- 4x + 4x) + (6y - 8y) = (- 4 + 4), simplifying gives

- 2y = 0 ⇒ y = 0

Substitute y = 0 in (1) or (2)

Substituting in (1) gives

2x - 0 = 2, that is

2x = 2 ( divide both sides by 2 )

x = 1

Solution is (1, 0 )

A pole that is 2.6 m tall casts a shadow that is 1.03 m long. At the same time, a nearby tower casts a shadow that is 46.25 m lo

photoshop1234 [79]

Answer:

Therefore the height of the tower is 116.75 m.

Step-by-step explanation:

Given that a pole that is 2.6 m tall casts a shadow that is 1.03 m long.

Here the height of a object directly proportional to the shadow. It means

Height of the object ∝ shadow

Height of the object= k.shadow

[k is the proportional constant.]

$\Rightarrow \frac{h}{s} =k$ [Height of object is denoted by h and shadow is denoted by s]

Then,

$\frac{h_1}{s_1} =k$ [h₁ is the height of the pole and s₁is the length of the shadow]

Again for the tower

$\frac{h_2}{s_2}=k$ [h₂ is the height of the tower and s₂ is the length of the shadow]

Therefore,

$\frac{h_1}{s_1}=\frac{h_2}{s_2} =k$

$\Rightarrow\frac{h_1}{s_1}=\frac{h_2}{s_2}$ ............(1)

Given $h_1 = 2.6 m$ , $s_1=1.03m$ and $s_2=46.25m$

Putting the value of $h_1,s_1$ and $s_2$ equation (1)

$\frac{2.6}{1.03}=\frac{h_2}{46.25}$

$\Rightarrow h_2 \times1.03= 2.6\times 46.25$ [cross multiplication]

$\Rightarrow h_2 = \frac{2.6\times 46.25}{1.03}$

$\Rightarrow h_2= 116.75$

Therefore the height of the tower is 116.75 m.
