A half times a half is a quarter. You can think of it this way: 1/2 is equivalent to 0.5, so you do 0.5 times 0.5 which is 0.25.(answer)
Answer: Multiplying and Dividing Decimals by Powers of 10
When you divide a decimal by a power of 10, simply move the decimal place to the left as many places as there are 0s in the power of 10.
Answer:
c =2
Step-by-step explanation:
2(6c+2)+3c=2 (19 -c)
1. Distribute
2(6c +2 ) + 3c = 2 ( 19 - C )
12c + 4 +3c = 2 (19 - C )
2. Combine like terms
12c + 4 + 3c = 2 ( 19 - c )
15c + 4 = 2 (19 - c )
3. Rearrange terms
15c + 4 = 2( 19 - C )
15c + 4 = 2 ( -c + 19 )
4. Distribute
15c + 4 = 2 ( -c + 19 )
15c + 4 = -2c + 38
5. Subtract 4 from both sides of the equation
15c + 4 = -2c + 38
15c + 4 -4 = -2c + 38 -4
6. Simplify
Subtract the numbers
Subtract the numbers
15c = -2c +34
7. Add 2c to both sides of the equation
15c = -2 +32
15c +2c = -2c + 34 + 2c
8. Simplify
Combine like terms
Combine like terms
17c = 34
9.Divide both sides of the equation by the same term
17c = 34
17c/17 = 34/17
10. Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
c = 2
To remember the ratios, use the mnemonic sohcahtoa.
S = O/H
C = A/H
T = O/A
In this case, we want S, sin. The side opposite angle X would be 24. The hypotenuse is 26, so the ratio is 24/26. <span />
