Answer:
C. 248°
Step-by-step explanation:
The arc measure of a full circle is 360 degrees.
Arc XZ measures 112 degrees.
Arcs XZ and XWZ add to a full circle, or 360 degrees.
The measure of arc XWZ = 360 degree - 112 degrees = 248 degrees
The answer might be 258 but idk
<span>We have 75 mL of 4% sugar solution.
We have to add a 30% sugar </span><span>solution to make a 50% </span><span>sugar solution.
75 * .04 + .30x = .50 * (75 +x)
3 + .30x = 37.5 +.50x
I can't get the equation to solve.
Did you type it correctly? For one thing, you have the percentages typed as .30 % and 4%. Are the decimal places in the correct positions?
Also, no matter how much 30% sugar solution you add, it will NEVER increase to 50%.
