Equivalent ration of b/40=9/10 b=____ ?

Mathematics
1 answer:
NARA [144]3 years ago
7 0

Answer:

The correct answer is <em>b = 36</em>

Step-by-step explanation:

In order to find out what b is, you must find out what 9/10 is.

9/10 is 0.9. This will later be used to check our answer.

Now, solve by using cross-multiplication

b * 10 = 9 * 40.

Then use the commutative property to reorder the terms

10b = 9 * 40

Now Multiply 9 * 40 = 360

10b = 360

Now divide both sides of the equation by 10

<em>b = 36</em>

In terms of rigid transformations (reflections, rotations, and translations), what does this difference represent?
makvit [3.9K]

Solution:

There are four kinds of rigid transformations.

1. Reflection

2. Rotation

3. Translation

4. Dilation

1.  The Meaning of term reflection is when we reflect something through a line or mirror the distance of object from line of reflection on both sides are same. The two images Preimage and image are congruent.

2.   Rotation means rotating an object or geometrical shape through an angle. An angle can be of any measure that is 0,30°,45°,90°,...... In rotation the two , image and preimage are congruent.

3.  While in translation , we shift something from a place to another place keeping the two images,that is image and preimage are congruent.

In all three,either in  reflection, rotation,or  translation  there is no change in shape and size, the two that is  image and Preimage are congruent.

A piece of wire is 8/9 meter long broke into two pieces. One piece is 2/3 meter long. How long is the other?
Genrish500 [490]

Answer:

<h2><em><u>2/9 is the answer.</u></em></h2>

Step-by-step explanation:

<em><u>1. First, make an equation.</u></em>

<em><u>Given:</u></em>

8/9 = length of wire

2/3 = length of a part of the wire

E = 8/9-2/3

<em><u>Unknown:</u></em>

Second part of wire

<em><u>2. Make the numbers have equal denominators</u></em>

2/3 * 3/3

= 6/9

<em><u>3. Solve</u></em>

8/9 - 6/9

= 2/9

Hope this helped,
