Two complementary angles measure (9x+27) and (x+50) degrees. what is the value of x?

Answers

Complementary angles mean that the sum is Equal to 90. So

(9x+27)+(x+50) = 90

10x + 77 = 90 (combine like terms)
10x = 13 (subtraction property of equality)
x=1.3 (division property of equality)

Answer:

***********o                                                         o**************

<----------(-4)--------(-2)--------(0)--------(-2)----------(4)-------------->

x>4 or x<-4

Step-by-step explanation:

You are looking for numbers that give you a distance, x, greater than 4 from 0. That wouldn't be anything between -4 and 4 because these would all give you a distance less than 4 from 0. So the answer would be to shade everything greater than 4 while also shading everything less than -4.

Here is a number line <-----|-----|-----|-----|-----|-----|-----|-----|-->

                                          -6    -4   -2    0     2     4    6    8

                                                 

Let's think about this more which of these numbers on this number line would satisfy |x|>4?

Numbers inside the numbers -4 and 4.

Or the numbers on the outside.

Let's try the inside numbers:

-2,02

|-2|>4

 2>4 is false which means -2 doesn't satisfy |x|>4

|0|>4

 0>4 is false which means 0 doesn't satisfy  |x|>4

|2|>4

 2>4 is false which means 2 doesn't satisfy  |x|>4

We could also try -4 and 4... but these will both give you a distance equal to 4 from 0.  And we are looking for greater than.

|-4|>4

 4>4 is false which mean -4 doesn't satisfy |x|>4

|4|>4

 4>4  is false which means 4 doesn't satisfy |x|>4

Now let's try the numbers on the outside:

-6,6,8

|-6|>4

 6>4 is true so -6 does satisfy |x|>4

|6|>4

 6>4 is true so 6 does satisfy |x|>4

|8|>4

 8>4 is true so 8 does satisfy |x|>4

So what I'm trying to do is convince you more that the only numbers that would satisfy |x|>4 are numbers outside the interval from -4 to 4.

So x>4 or x<-4.

On a number line the solution would look like this:

***********o                                                         o**************

<----------(-4)--------(-2)--------(0)--------(-2)----------(4)-------------->

We have holes at -4 and 4 to mean we do not include those numbers.  We would have if the inequality read |x| \ge 4.  The line underneath this inequality means to include or equals.  We do not want to include; we did not have the equal sign.   The only difference between the two solutions would be to fill the holes if you |x| \ge 4.

***********o                                                         o**************

<----------(-4)--------(-2)--------(0)--------(-2)----------(4)-------------->

Alana and her friends decided to have a water fight on a hot summer day. They filled a bunch of water balloons and started the fight at 12:20 P.M. The water balloons lasted for 25 minutes. When all the water balloons were gone, they sprayed water with hoses for 55 minutes, until Alana's dad showed up with ice cream. What time was it when the water fight ended?

Answers

The time was it when the water fight ended is when they started the fight at 12:20 P.M. at 1:40 P.M.

To find out what time the water fight ended, you can start with the initial time when they began the water fight (12:20 P.M.) and then add the duration of the water balloon fight and the hose spraying.

Water balloons lasted for 25 minutes, and spraying water with hoses lasted for 55 minutes, so:

Total duration = 25 minutes (water balloons) + 55 minutes (hose spraying)

                        = 80 minutes

Now, add these 80 minutes to the starting time:

12:20 P.M. + 80 minutes = 1:40 P.M.

So, the water fight ended at 1:40 P.M.

A circle with a radius of 4 in, is dilated by a scale factor of 5. What will be the circumference of the circle after dilation?21 in

Answers

Ok so circumference=2*pi*radius. So We know that the radius is dilated by a scale factor of 5, so we can put 2*pi*20. For pi you can use So when we multiply 2*pi*20, you get 125.6637
