Answer:

He scored 79\frac{1}{2} points.

Step-by-step explanation:

Given:

Number of points for a correct answer = 2\frac{1}{2}

Number of points scored for an incorrect answer = -\frac{1}{4}

Therefore, for 35 correct answers, points scored = 35\times 2\frac{1}{2}=35\times \frac{5}{2}=\frac{175}{2}

Now, for 32 incorrect answers, points scored = 32\times -\frac{1}{4}=-\frac{32}{4}=-8

Therefore, net number of points scored by Nathan is:

\frac{175}{2}-8=\frac{175}{2}-\frac{16}{2}=\frac{175-16}{2}=\frac{159}{2}=79\frac{1}{2}

Therefore, Nathan scored 79\frac{1}{2} points.

What is the value of the expression 4rs if r = -1/3 and s = 7/8
Brut [27]

1 and 1/6 is the correct answer because 4/1 multiplied by 1/3 is 4/3. 4/3 multiplied by 7/8 is 28/24 or 1 and 4/24, which can be simplified down to 1 and 1/6.

Answer:   a) -240

<u>Step-by-step explanation:</u>

2\sqrt{-32}\cdot 5\sqrt{-18}\\\\=2\cdot 5\sqrt{-32\cdot -18}\\\\=10\sqrt{-1\cdot 2\cdot 2\cdot 2\cdot 2\cdot 2\cdot -1\cdot 2\cdot 3\cdot 3}\\\\\\=10(-1\cdot 2\cdot 2\cdot 2\cdot 3)\\\\=10(-24)\\\\=\boxed{-240}

Which of the following is true of rounding the optimized solution of a linear program to an integer?
VashaNatasha [74]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

the optimized solution of a linear program to an integer as it does not affect the value of the objective function.

As if we round the optimized solution to the nearest integer, it does not change the objective function .

while it is not true that it always produces the most optimal integer solution or feasible solution.

Hence, Option 'c' is correct.
