1. There are 78 sophomores at a school. Each is required to take at least one year of either chemistry or physics, but they may

SVETLANKA909090 [29]

We are given that there are a total of 78 students. If we set the following variables:

$\begin{gathered} C=\text{students only in chemestry} \\ P=\text{students only in physics} \\ PC=\text{students in physics and chemistry} \end{gathered}$

Then, the sum of all of these must be 78, that is:

$C+P+PC=78$

Since there are 15 in chemistry and physics and 47 in chemistry, we may replace that into the equation and we get:

$47+P+15=78$

Simplifying:

$62+P=78$

Now we solve for P by subtracting 62 on both sides:

$\begin{gathered} 62-62+P=78-62 \\ P=16 \end{gathered}$

Therefore, there are 16 students in physics

If he puts in $25 every month and there are 12 months in one year, just multiply 25 by 12 to find that Maurice will save $300 a year.

If 3x^2 -2x+7=0, then(x-1/3)^2=

Harman [31]

3x² - 2x + 7 = 0.

Using method of completing the square.

3x² - 2x = 0 - 7

3x² - 2x = -7 Divide through by 3.

x² - 2/3x = -7/3 ...........(d)

Coefficient of x = -2/3, half of it = 1/2*-2/3 = -1/3 square of it = (-1/3)² = 1/9

We add (1/9) to both sides of equation (d)

x² - 2/3x = -7/3

x² - 2/3x + 1/9 = -7/3 + 1/9

We factorize it by making using of half of the coefficient, -1/3

(x - 1/3)² = -7/3 + 1/9

(x - 1/3)² = -20/9

That's the answer as asked by the question. -20/9
