How to quickly convert degrees to radians?

1 answer:

4 0

180 degrees is the same as $\pi$
So if you have to convert 60 degrees to radians, do it like this:
$60* \frac{ \pi }{180}$
Then you reduce between the 60 and the 180. 60 goes into itself once and into 180 3 times, so 60 degrees is the same as $\frac{ \pi }{3}$

Answer:

To find how tall he was at the end of the school year, you add his height at the beginning of the year and during the school year. First you should just add the inches.

2 1/4 + 7/8

The common denominator is 8.

2 2/8 + 7/8

2 9/8

3 1/8

Put back in the 5 ft.

So, Jerry was 5ft and 3 1/8 inches at the end of the school year.

IXL Question! Brainliest + 5-star!

Nitella [24]

Step-by-step explanation:

First, count the total number of the boxes from the figure. This can be done easily by counting the number of the rows and then the number of the columns and multiplying the numbers.

=> 10 x 10 = 100 boxes.

Now, count the shaded boxes. It's 8.

Now, we calculate percentage by,

=> Selected boxes/Total boxes x 100

Putting the values,

=> 8/100 x 100

=> 8%

Hope it helps :)

Graph the system of equations. {2x - y =4 {x - y = -2

Mnenie [13.5K]

Answer:

See attachment

Step-by-step explanation:

The given system is

2x-y=4

x-y=-2

We write the system in slope-intercept form:

y=2x-4

y=x+2

The first equation has slope of 2 and y-intercept at (0,-4)

When y=0, x=2.

We plot (0,-4) and (2,0) to graph this first equation.

The second equation has a slope of 1 and a y-intercept at (0,2)

Also when y=0, x=-2.

We plot (0,2) and (-2,0) and draw a straight line through them.

The graph of the system is shown in the attachment.
