Answer:
Answer:-4e-9

Start by combining like terms. I put like terms in parentheses so you can see them, but they are not needed.


That's it.
The answer is B) 1.9 you need to use Pythagoras where a^2+b^2=c^2, so at 9 o'clock it will make a right angle triangle so the square root of 1.5^2+1.2^2 is 1.92093... rounded it is 1.9
Answer:
15 oz.
Step-by-step explanation:
<u>Rounding to the nearest ounce:</u>
1<u>4</u>.853
<u>Rounding notes:</u>
If the number one place to the right of the rounding number is greater than 5, the number increases by 1.
If the number one place to the right of the rounding number is less than 5, the number stays the same and anything to the right of the rounding number changes to 0.
<u>Work:</u>
4 represents the 'ounces' place value.
To identify the rounding of 4, we need to determine if the value 8 is greater than 5, or less than 5.
8 > 5, meaning 4 increases to 5.
New rounded number = 15 oz.
90b + 150g > 500
0.35b + 2.50g < 15.00
what, is the question asking. These might help
