Answer:
-18.50490621
Step-by-step explanation:
To solve, take -64/3.
15.75 divided by 0.25
In every 1 whole number, there are 4 of 0.25
Now we have 15 as whole number so simply multiply 15 x 4
15 * 4 = 60, there are 60 pieces of .025s in 15.
0.75 has 3 0.25s
Now, let’s add 60 + 3 = 63, the answer is 63.
There are 63 pieces of 0.25 in 15.75.
15.75 / 0.25
63
25% reduced
you take 337.50 divide by 450 which gives you .75
so you take 100% minus 75% and you get 25%
you can check the work by taking 450 time .25 which gives you 112.5 . and subtract that from 450 you'll end up with 337.50
That would be choice 2. One acute angle is the complement of the other
eg in a 90-60-30 triangle sine 30 = cos 60
