<span>Simplify -1.7+0.4+(-0.8)+0.3?
</span>
Answer is -1.8
First do parenthesis
12.3*108=1328.4
1.06*10-7= 3.6
multiply them together
1328.4*3.6=4,782.24
So 4,782.24 is the answer
yes.
yes
yes.
see if it worked good luck bro
The solution is 40% acetic acid.
Multiply the amount of the solution by 40%:
15 liters x 0.40 = 6 liters
There is 6 liters of acetic acid
We know that :
⊕ Sum of the three angles in a triangle should be equal to 180°
Given : Angle BAC = 50° and Angle ABC = 75°
⇒ Angle BAC + Angle ABC + Angle ACB = 180°
⇒ 50° + 75° + Angle ACB = 180°
⇒ 125° + Angle ACB = 180°
⇒ Angle ACB = 180° - 125°
⇒ Angle ACB = 55°
