Answer:
terminating
Step-by-step explanation:
20 is a factor of a 100
20 × 5 = 100
therefore 19 × 5= 95
So in decimal form it's 2.95
If one-sixth of a certain number is four more than one-twelfth the number, the required number will be 48.
Let the unknown number be 'a'
One-sixth of the number is expressed as 1/6 a ..... 1
One-twelfth the number is also expressed as 1/12 a
Four more than one-twelfth the number will be written as:
1/12 a + 4 .... 2
Equating 1 and 2 will give:
1/6 a = 1/12 a + 4
a/6 = a/12 + 4
Collect the like terms
Find the LCM
Cross multiply
a = 12×4
a = 48
This shows that the required number is 48

<u><em>The complete question is</em></u>
Bianca is trying to find the area of this rectangle. She already measured one side as 10 cm. Which other length(s) could she measure to use in her area calculation?
The picture of the question in the attached figure
we know that
The area of rectangle is equal to
where
L is the length of rectangle
W is the width of rectangle
Remember that
The opposite sides of a rectangle are parallel and congruent and the measure of each interior angle is 90 degrees
That means---> The length and the width are perpendicular
In this problem we have
we have that
The width is equal to
so
The area of rectangle is equal to
or
therefore
To find out the width, Bianca could measure segments b or c, because they form a 90 degrees angle with the length
First, let's prove that triangle ABC and AFG are similar.
Line segment FG and BC are parallel to each other, that's a given.
With this information, we can state that these sides are similar to each other since you can transform BC on to FG using only rigid transformations and dilations.
Another thing is that both of these triangles share angle A, that's a given. Therefore, using the SA similar theorem, we can conclude that these triangles are similar.
Now that we know that triangle ABC and AFG are similar we may start going to the answer box.
We can eliminate the first three answer choices for having sides we cannot make full conclusions due to limited knowledge.
The only answer remaining is the fourth choice.
