If 45% of a number n is 225 what is 75% of n

Tpy6a [65]

75% of n is 375.

Step-by-step explanation:

Given,

45% of a number n = 225

We will find n first.

$\frac{45}{100}n=225\\0.45n=225$

Dividing both sides by 0.45

$\frac{0.45n}{0.45}=\frac{225}{0.45}\\n=500$

Now we have to find 75% of n.

75% of n = $\frac{75}{100}*500=75*5$

75% of n = 375

75% of n is 375.

Which transformation was applied to ABC to transform it to DEF?

kow [346]

Answer:

So the Answer will be D.

Step-by-step explanation:

Cuz if you look it up online it will give you words or maybe links that youu shouldn't look at cuz they don't really give it to you. It shows that ''<u>A rotation</u> turns each point on the preimage a given angle measure around a fixed point or axis. Each point on triangle ABC is rotated 45° counterclockwise around point R, the center of rotation, to form triangle DEF.'' So indee that D. is right. (I am only 11 and i am helping lol)
