65*7=(1+1+1+1+1+1+1)=65+65+65+65+65+65+65=455 she did 65 sit ups every day for one week the expression is right there the answer to solve it is 455. :)

lots of toys were in the swimming pool. the pool had 15 hoops in it. what is the value of each line in the graph?

Volgvan

Each line indicates the amount of a certain object.

We already know that the value of the green line is 15, all that is left to do is find the rest . . .

<u>Values</u>

Red Line: 20

Orange Line: 60

Green Line: 15

turquoise Line: 45

Blue Line: 65

Your welcome :3

Take a moment to think about what tan(θ) represents.1. Use interval notation to represent the values of θ (between 0 and 2π) whe

Nonamiya [84]

Let's first get the representation of tan

We also need to understand how to convert radians to degrees

$\begin{gathered} \frac{\pi}{2}=90^0 \\ \pi=180^0 \\ \frac{3\pi}{2}=270^0 \\ 2\pi=360^0 \end{gathered}$

For question 1

since tan > 1

It must be in either first quadrant or third quadrant as shown in the diagram above

$\begin{gathered} \text{ } \\ \frac{\pi}{4}$
