So first 15/100 which is 15 percent and out of 20, thats 15.
20. 100. 100X15 divided by 20 which is 75. I did cross multiplication ok. So I just did 20 times 15 and then divided by 100
The simple interest formula<span> allows us to calculate I, which is the </span>interest<span> earned or charged on a loan. According to this </span>formula<span>, the amount of </span>interest<span> is given by I = Prt. We calculate as follows:
14.65 = P (.025)(2)
P = $293</span>
With y-x=0, add x to both sides to get y=x.
Now you can substitute either x or y
7x-9x=8 or 7y-9y=8 which is the same thing
-2x=8 or -2y=8
x=-4 or y=-4
Hope this helped!
Answer:
The scale factor of dilation is 2.
Step-by-step explanation:
From the given information it is notices that the vertices of preimage are A(1, 4), B(3, 4), C(3, 1), and D(1, 1). The vertices of image are A'(2, 8), B'(6, 8), C'(6, 2) and D'(2, 2).
The scale factor is the ratio of distance of a image of a vertex from the center of dilation and distance of the vertex from the center of dilation.
The center of dilation is origin. So, the scale factor is
.... (1)
Distance formula:
Now, put these values in equation (1).
Therefore the scale factor of dilation is 2.
The length of CD will be 3
From given diagram, triangle ABC and EDC meet at a common vertex C.
So, triangle ABC and EDC both are congruent to each other.
Applying the similarity property of congruence, ratio of the congruent triangles' corresponding sides will be equal.
Therefore,
Simplifying the expression,
We get
Multiplicating the terms in right hand side,
Solving 6x on both sides,
we get
Dividing both the sides by 24, we get
Hence, the length of CD is 3.
