Answer: 65 people completed graduate school.
Step-by-step explanation:
25% of 260 is 65.
The equation of the unit circle is
x^2 + y^2 = 1
If x = 5/8, then solving for y
(5/8)^2 + y^2 = 1
y^2 = 1 - 25/64
y^2 = 39/64
y = sqrt(39/64)
We use the positive square root because positive x-coordinate and positive y-coordinate is in the first quadrant.
Therefore the answer to this question is sqrt(39)/8
I think the answer is $48
Answer:
<em><u>x=-2</u></em>
Step-by-step explanation:
<u>Let's solve your equation step-by-step.
</u>
<em>3x+9=x+5
</em>
<u>Step 1: Subtract x from both sides.
</u>
<em>3x+9−x=x+5−x
</em>
<em>2x+9=5
</em>
<u>Step 2: Subtract 9 from both sides.
</u>
<em>2x+9−9=5−9
</em>
<em>2x=−4
</em>
<u>Step 3: Divide both sides by 2.
</u>
<em>2x
/2=-4/2</em>
<em>x=−2
</em>
