487 divided by equals 60.825 because 8 can't go into 4 but it can go into 48 6 times so then you can't do 8 divided by 7 so you have to add a zero and a decimal so that's how you get 60.825
25% is equal to 1/4 or .25 of a whole.
If you do 10 divided by .25 you get 40.
10 is 25% of 40.
-2/3 is the simplified form of the expression -1/2 ÷ 3/4.
<h3>What is the simplified form of the given expression?</h3>
Given the expression in the question;
-1/2 ÷ 3/4
To divide by a fraction, multiply by its reciprocal.
-1/2 ÷ 3/4
Reciprocal of 3/4 is 4/3
Hence
-1/2 × 4/3
Next, we cancel out the common factor of 2
Factor out 2 from 4
-1/2 × 2(2)/3
-1/1 × 2/3
( -1 × 2 ) / ( 1 × 3 )
(-2) / (3)
-2/3
Therefore, the simplified form is -2/3

Answer:
pls dont kill me for wacky lines. this shall just give you a basic idea. the important part is the 90° angle
Answer:
Step-by-step explanation:
We will use the co-function identity for sine, where:
Since sin(21)=0.358=cos(x). This means that:
Solve for x. Add x to both sides:
Subtract 21 from both sides:
Hence:
