The fraction of the reading assignment done by Tuesday night is 1/2.

<h3>What are fractions?</h3>
  • Fractions are the numbers that make up a portion of the whole. An object or a collection of objects can be a whole.
  • If a quantity or item is divided into equal pieces, each piece will represent a portion of the entire.
  • A fraction is represented by the ratio a/b, where a represents the numerator and b is the denominator.

Given:

Let the total reading assignment be x.

Fraction of the reading assignment finished by Tori on Monday afternoon = (1/6)x

Fraction of the reading assignment finished by Tori on Tuesday afternoon = (1/3)x

The fraction of the reading assignment done by Tuesday night is,

Total - Fraction of the reading assignment completed by Tori

= x -(\frac{x}{6} + \frac{x}{3} )

= x -(\frac{x+ 2x}{6}  )

= x - \frac{3x}{6}

= x -\frac{x}{2}

= \frac{2x-x}{2}

= \frac{x}{2}

So, 1/2 of the reading assignment(x) was done by Tuesday night.

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 3x² - 7x

f(-2) is x = -2

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em>:                    f(-2) = 3(-2)² - 7(-2)
  2. Exponents:                          f(-2) = 3(4) - 7(-2)
  3. Multiply:                               f(-2) = 12 + 14
  4. Add:                                     f(-2) = 26

a surveyor measures the distance to the two landmarks as shown in the diagram what is the distance d. between the landmarks​
Inessa [10]
<h3>The distance between two landmarks is 123 meters</h3>

<em><u>Solution:</u></em>

We have to find the distance between two landmarks

<em><u>Use the law of cosines</u></em>

The third side of a triangle can be found when we know two sides and the angle between them

c^2 = a^2 + b^2 - 2ab\ cos c

Here, angle between 90 meters and 130 meters is 65 degrees

From figure,

a = 90

b = 130

c = d

Therefore,

d^2 = 90^2 + 130^2 - 2(90)(130)\ cos 65\\\\d^2 = 8100 + 16900 - 23400\ cos\ 65\\\\d^2 = 25000 - 23400 \times 0.4226\\\\d^2 = 25000 - 9889.267\\\\d^2 = 15110.73\\\\d = 122.92\\\\d \approx 123

Thus, the distance between two landmarks is 123 meters
