denis-greek [22]

Answer:

38.60mm

Step-by-step explanation:

Step one:

Given data

We are given that the dimension of the triangles are length 23 mm and 31 mm

Let us assume that the triangle is a right angle triangle

Step two:

Applying the Pythagoras theorem we can find the third as

z^2= x^2+y^2\\\\z^2= 31^2+23^2\\\\z^2= 961+529\\\\z^2= 1490\\\\

square both sides

z= √ 1490

z= 38.60mm

Hence a possible dimension of the third side is 38.60mm

What is the sum of 4.9 × 102 and 6.8 × 103?
dusya [7]

Answer:

The sum is

7.92\times 10^3

Step-by-step explanation:

We want to add

4.9\times 10^2 and 6.8\times 10^3

The sum of these two numbers is:

4.9\times 10^2 +6.8\times 10^3

This is the same as:

4.9\times 100 +6.8\times 1000

490 +6800=7290

We rewrite 7290 in standard form to get;

7.92\times 10^3
