How many times greater is the value of 5 in 3,590 than the value of 5 in 359 ?
Tresset [83]

Answer:

10 times greater is the value of 5 in 3,590 than the value of 5 in 359.

Step-by-step explanation:

To find : How many times greater is the value of 5 in 3,590 than the value of 5 in 359 ?

Solution :

The place value stem is

Thousand     Hundred     Tens    Ones

  1000               100            10         1

The value of 5 in 3,590 is at hundred place

So, 5\times 100=500

The value of 5 in 359 is at tens place

So, 5\times 10=50

Number of time greater is the value of 5 in 3,590 than the value of 5 in 359 is given by,

n=\frac{500}{50}

n=10

Therefore, 10 times greater is the value of 5 in 3,590 than the value of 5 in 359.

Given: ABCD is a quadrilateral, BC║AD, m∠ A = 90°
Lina20 [59]

Answer:

  Rearrange the equations that result from use of the Pythagorean theorem.

Step-by-step explanation:

Transversal AB crossing parallel lines AD and BC makes supplementary interior same-side angles A and B. Since A = 90°, B must be 90°. The Pythagorean theorem then applies in the right triangles ABC and ABD.

We can use that theorem to write two expressions for AB^2:

  BD^2 -AD^2 = AB^2 = AC^2 -BC^2

The middle expression, AB^2, isn't needed beyond this point. Adding (AD^2 -AC^2) to both sides of the equation gives the desired result:

  BD^2 -AC^2 = AD^2 -BC^2
