What do all similar circles have in common?

Mathematics
1 answer:
Art [367]3 years ago
8 0

Answer:

Explanations (4) Similarity is a quality of scaling: two shapes are similar if you can scale one to be like the other, like these triangles ABC and DEF. Since all circles are of the same shape (they only vary by size), any circle can be scaled to form any other circle. Thus, all circles are similar!

The Walden University has 47,456 students in 2010, while Kaplan university had 77,966 students. Complete the following:
Umnica [9.8K]

We have been given that The Walden University had 47,456 students in 2010, while Kaplan university had 77,966 students. We are required to compare the number of students in each of these universities in different ways.

(A) Let us first find difference between the number of students between the two universities. The difference between the number of students for two universities is 30510.

Let us now find what percentage is 30510 of 47456.

\frac{30510}{47456}\times 100 = 64.29 \%

Therefore, Kaplan’s enrollment was 64.29% larger than Walden’s

(B) In order to answer this part, we need to find what percentage is 30510 of 77966.

\frac{30510}{77966}\times 100 = 39.13 \%

Hence, Walden’s enrollment was 39.13% smaller than Kaplan’s.

(C) In this part we need to figure out what percentage is 47456 of 77966.

\frac{47456}{77966}\times 100 = 60.87 \%

Thus, Walden’s enrollment was 60.87% of Kaplan’s.

Note: Please round your answers to required number of decimal values.
