How do I turn this rad into degrees with no calculator? 4pi/5?

You need to know that pi rad = 180°

Then 4 pi / 5 rad = 4 (180°) / 5

Those are numbers that you can multiply and divide wihout calculator and the result is 720 °/ 5 = 144 °

What is the slope of the line shown below? (-2,-3) (-4,-9)

gogolik [260]

Answer:

Slope = 3

Step-by-step explanation:

Slope = (y2-y1)/(x2 - x1)

In this case,

Slope = (-9 + 3) / (-4 + 2)

= -6/-2

= 3

For the right triangle shown, the lengths of two sides are given. Find the third side. Leave your answer in simplified, radical

sleet_krkn [62]

Answer: $c=4\sqrt{2}$

Step-by-step explanation:

For this exercise you need to apply the Pythagorean Theorem. This is:

$h^2=l^2+m^2$

Where "h" is the hypotenuse of the Right triangle and "l" and "m" are the legs.

In this case, you can identify that:

$h=c\\\\l=a=4\\\\m=b=4$

Knowing these values, you can substitute them into $h^2=l^2+m^2$ :

$c^2=4^2+4^2$

Now you must solve for "c":

$c=\sqrt{4^2+4^2}$

Evaluating, you get:

$c=\sqrt{16+16}\\\\c=\sqrt{32}$

To simplify the result:

- Descompose 32 into its prime factors:

$32=2*2*2*2*2=2^5$

- By the Product of powers property, you know that:

$2^5=2^4*2$

- Make the substitution:

$c=\sqrt{2^4*2}$

- Finally, knowing that $\sqrt[n]{a^n}=a$ , you get:

$c=2^2\sqrt{2}\\\\c=4\sqrt{2}$

The ratio of blue jays to Robin's was 6 to 7. If there were 84 Robins, how many blue jays were there?

Paul [167]

Answer:

72

Step-by-step explanation:

<em>Since the ratio of blue jays to robin's was 6 to 7 then if there were 84 robins how many blue jays were there.</em>

<em>6 to 7 can also be express as 6/7</em>

<em>Thus, we can set up a proportion</em>

<em>6/7 = x/84</em>

<em>Now, we have to solve for x</em>

<em>x = 72</em>

<em>Hence, if there were 84 robin there would be 72 blue jays.</em>

The length of a rectangle solid is 3.0 m the width is 0.6 meter, and the height is 0.4 meter. Find, to the nearest tenth, the nu

Ad libitum [116K]

Answer:

$0.72\,\,m^3$

Step-by-step explanation:

Given:

Length of a rectangle solid = 3 m

Width of a rectangle solid = 0.6 m

Height of a rectangle solid = 0.4 m

To find: Volume of the solid

Solution:

Volume of the solid = length × breadth × height

$=3\times 0.6\times 0.4=0.72\,\,m^3$

So, the number of cubic meters in the volume of the solid is $0.72\,\,m^3$
