A scale factor "from A to B" is a number that multiplies some dimension of A to make it equal to the corresponding dimension of B. That is, ...
(scale factor A to B) = (dimension of B)/(corresponding dimension of A)

Your triangles have one corresponding dimension. On triangle A, it is 6 ft. On triangle B, it is 5 ft. Using the above formula, we have
(a) (scale factor A to B) = (5 ft)/(6 ft) = 5/6

The reverse is also true. That is, ...
(b) (scale factor B to A) = (dimension of A)/(corresponding dimension of B)
(scale factor B to A) = (6 ft)/(5 ft) = 6/5

(c) The scale factors are reciprocals of each other.

The sum of three consecutive numbers is equal to 4 times the largest number minus 29. What is the smallest of the three numbers?

gulaghasi [49]

The smallest of the three consecutive integers is 24.

<h3>How to solve algebraic word problems?</h3>

Let the 3 consecutive integers be;

x, y and z

Thus;

y = x + 1

z = x + 2

Now, we are told that their sum is equal to 4 times the largest number minus 29. Thus;

x + x + 1 + x + 2 = 4(x + 2) - 29

3x + 3 = 4x + 8 - 29

4x - 3x = 3 + 21

x = 24

Thus, we can conclude that the smallest of the three consecutive integers is 24.

Question 5(Multiple Choice Worth 1 points)

azamat

Answer: Second option.

Step-by-step explanation:

As you can observe in the picture given in the exercise, there are two Right triangles formed inside the rectangle: CDA and ABC.

You need to use the Pythagorean Theorem to solve this exercise. This is:

$a^2=b^2+c^2$

Where "a" is the hypotenuse and "b" and "c" are the legs of the Right triangle.

If you solve for one of the legs, you get the following equation:

$a^2-c^2=b^2\\\\b=\sqrt{a^2-c^2}$

In this case, you can identify in the figure that:

$a=AC=65\ m\\\\b=BC=x\\\\c=AB=63\ m$

Finally, you must substitute these known values into the equation $b=\sqrt{a^2-c^2}$ and then evaluate in order to find the value of "x". You get that this is:

$x=\sqrt{(65\ m)^2-(63\ m)^2}\\\\x=16\ m$
