Answer:
<em>Equation:
</em>
<em>HCL + HCL = HCL
</em>
<em><u>0.30x + 0.45(50-x) = 0.35*50
</u></em>
<em><u>Multiply thru by 100 to get:
</u></em>
<em><u>30x + 45*50 - 45x = 35*50</u></em>
<em><u>-15x = -10*50
</u></em>
<em><u>x = (2/3)50
</u></em>
<em><u>x = 33 1/3 liters (amt. of 30% solution needed in the mixture)
</u></em>
<em><u>50-x = 16 2/3 liters (amt. of 45% solution needed in the mixture)
</u></em>

Answer:
The new coordinates are (-11, -35)
Step-by-step explanation:
When reflecting across the x-axis, you are just the Y. value. It is the opposite due to the fact that if you're moving something across the horizontal x-axis, it's actually the vertical height changing. So, you just inverse the Y value to its' negative or positive reciprocal.
Answer:
Step-by-step explanation:
To construct a box plot, use a horizontal or vertical number line and a rectangular box. The smallest and largest data values label the endpoints of the axis. The first quartile marks one end of the box and the third quartile marks the other end of the box. Approximately the middle 50 percent of the data fall inside the box. The “whiskers” extend from the ends of the box to the smallest and largest data values. The median or second quartile can be between the first and third quartiles, or it can be one, or the other, or both. The box plot gives a good, quick picture of the data.
Answer:
16-(-2)/ -6-(-4)= 18/-2= -9
Step-by-step explanation:
y2-y1/ x2-x1
Answer:
Period of the given harmonic function is 1.
Step-by-step explanation:
In any harmonic function which is in the form of y = asin(bx+c) + d , we know
Period of this function will be represented as P =
Therefore for the given function d = 5 sin (2πt) we know the value of B is 2π.
So the period will be P =
The answer is period = 1
