vagabundo [1.1K]

Answer:

Follows are the solution to this question:

Step-by-step explanation:

In point a:

$\to \frac{5 \pi }{6}$

calculating a positive coterminal angle:

$\to \frac{5 \pi }{6} + 2 \pi \\\\ \to \frac{5 \pi +12 \pi }{6} \\\\ \to \frac{17 \pi }{6} \\\\$

calculating negative coterminal angle:

$\to \frac{5 \pi }{6} -2\pi \\\\ \to \frac{5 \pi - 12 \pi }{6} \\\\ \to \frac{ - 7 \pi }{6} \\\\$

In point b:

$\to \frac{-9 \pi }{4}$

calculating a positive coterminal angle:

$\to \frac{ -9 \pi }{4} + 2 \pi \ \ = \frac{-9 \pi + 8 \pi }{4} \\\\$

$\to \frac{ - \pi }{4} + 2 \pi \ \ = \frac{- \pi + 8 \pi }{4} \\\\$

$= \frac{ 7 \pi}{4}$

calculating a negative coterminal angle:

$\to \frac{ -9 \pi }{4} - 2 \pi \\\\ \to \frac{-9 \pi - 8 \pi }{4} \\\\ \to \frac{-17 \pi }{4}$

There are 3 times as many dogs as cats.

vazorg [7]

Answer:

there are 12 dogs.

Step-by-step explanation:

d= dogs now plug in the 4 into your equation.

c= cats d=3(4)

d+c=16 d=12

3c+c=16

4c=16 SO THEREFORE THERE ARE 12 DOGS :)

c=4

Karen is typing a report.she typed 3/8of the pages in the report in the morning and 2/5 of the pages in the afternoon.what fract

Karolina [17]

Simple...

you have $\frac{3}{8}$ and $\frac{2}{5}$

Just subtract...but first find a common denominator...

Use 40 as the common denominator...

$\frac{3}{8} * \frac{5}{5} = \frac{15}{40}$
and
$\frac{2}{5} * \frac{8}{8} = \frac{16}{40}$

So, subtract,

$\frac{15}{40}
-
 \frac{16}{40}$

= $- \frac{1}{40}$

Thus, your answer.

Maya reads that 0.63 of Oak School is female and 0.47 of Elm School is female. She says that Oak School must have more females.

-BARSIC- [3]

Answer:

No not correct

Step-by-step explanation:

We are given information that Maya came to know that 0.63 pf Pal school is female and 0.47 of Elm school is female.

Without knowing the total number of students in each school, we cannot conclude that 0.63 is greater than 0.47

For example, say number of students in Oak school be 100, and in Elm school be 200

Females in Oak school = 0.63(100) =63

Females in Elm school = 0.47(200) = 94

We find that there are more females in Elm school

So with the information given, we cannot conclude she is correct , there are chances for her being wrong also.
