Quinn has 6 bottles of water that each weigh 3/5 pound. What is the total weight of the water bottles? Use the number line to he

olganol [36]

Answer:

The weight of 6 bottles = $3\frac{3}{5}\ pounds$ or $3.6\ pounds$

Step-by-step explanation:

Given:

Total number of bottles = 6

Weight of each bottle = $\frac{3}{5}$ pound

To find the total weight of 6 bottles.

Solution:

We can plot the number line for six bottles.

We can the plot the weights in another number line.

Each unit represents $\frac{3}{5}$ pound of weight.

As the number of bottles increase the number of pounds of weight increase by $\frac{3}{5}$ .

Thus, weight of 6 bottles = $\frac{3}{5}+\frac{3}{5}+\frac{3}{5}+\frac{3}{5}+\frac{3}{5}+\frac{3}{5}$ $=\frac{18}{5}$ pounds

Converting fraction to mixed number.

$\frac{18}{5}=3\frac{3}{5}$ pounds

Or in decimals $\frac{18}{5}=3.6\ pounds$

Thus weight of 6 bottles = $3\frac{3}{5}\ pounds$ or $3.6\ pounds$

Find the measure of one interior angle in each regular polygon. Round your to nearest tenth if necessary.

e-lub [12.9K]

The value of the interior angle of the regular polygon is calculated using the formula (n - 2) 180 / n where n is the number of sides of the regular polygon.

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

A regular polygon refers to a multi-sided convex figure where all the sides are equal in length and all the angles have equal degree measures.

The triangle has 3 interior angles of 60 degrees

The square has 4 interior angles of 90 degrees.

The pentagon has 5 interior angles of 108 degrees .

The formula for the interior angle of a regular polygon is given by,

( n − 2 ) 180 / n

where n refers to the number of sides.

Triangle : (3 - 2) 180 / 3 = 60 degree.

Square : (4 - 2) 180 / 4 = 90 degree.

Pentagon: (5 - 2) 180 / 5 = 108 degree.

Consider this equation. cos(θ)= -3/10 If θis an angle in quadrant II, what is the value of tan (θ)?

Alja [10]

Answer:

Step-by-step explanation:

Trigonometry ratio:

$\sf Cos \ \theta = \dfrac{Adjacent \ side}{hypotenuse}=\dfrac{-3}{10}$

We need to find the opposite side using Pythagorean theorem.

opposite side² = hypotenuse² - adjacent side²

= 10² - (-3)²

= 100 - 9

= 91

opposite side = √91

$\sf tan \ \theta = \dfrac{opposite \ side}{adjacent \ side}$

$\sf = \dfrac{\sqrt{91}}{3}$

In quadrant II, value of tan $\theta$ is negative.

$\sf tan \ \theta = -\dfrac{\sqrt{91}}{3}$
