Hello!
A figure only becomes bigger if it is dilated. This figure is reflected, not dilated, so A is not the answer.
Shapes are similar if the ratios of their corresponding side lengths match. Basically, they are the same shape but can be in a different size or direction. In our case each side is the same length, and they are both triangles. Therefore these shapes ARE similar, so be could be the answer.
If you were to rotate the two triangles and look at the angles that were in the same spot, those are corresponding angles. They would have the same angle measure. If you were to turn each triangle tip pointing up, (S,R') would have the same angle measure, along with (R, S') and (T,T'). As you can see, R is equal to S', so C could also be the answer.
In D we can see that R corresponds to S', not T, so D is not the answer.
Now we are torn in between B and C. C is just explaining one angle. B is saying that the shapes are similar. This would mean that all of their corresponding angles. C is just an example of B. B has it all in one. Therefore, our answer is B) <span>Figure RST is similar to figure R′S′T′.
I hope this helps!</span>

Answer:
f. 260 in by 100 in
Step-by-step explanation:
13 + 5 = 18
720/18 = 40
Find length:
40*13 = 520
520/2 = 260 <-- must divide by 2, 520 is the sum of twice the length
Find width:
40*5 = 200
200/2 = 100 <-- must divide by 2, 200 is the sum of twice the width
Answer:
9/50
Step-by-step explanation:
Turning 18% to a decimal= .18. As you turn the decimal to a fraction, it gives you 9/50
9/50= .18
Answer: I believe his earnings would be 187$ once he teaches 7 classes.
Step-by-step explanation:
$187-$68=$111
17 x ? = 119
(take the 17$ which is the amount of money he'll earn each class and divide by 111. as seen below:
$111/17$=$6.5 (round to $7)
(you then plug in the 17 for 7 x ? = 119)
7x17=119
now you have to add the 68$ that he will get per month.
119+68=187
then you get 187$ which he had spent on the certificate
