What we need to do is find out what 29% of 639 is and add it to 639 to find the total.  The easiest way to find a percentage of a number, if you don't know how to calculate it, is by taking 10%.  So 10% of 639 is 63.9.  Now since there is 29%, we need to multiply 63.9 x 2, to get 127.8.  However, we only have 20% out of the 29%.  So we need to find the other 9%.  If 10% is 63.9, then 1% is 6.39.  So we need to multiply 6.39 x 9, and that equals 57.51.  Now, we need to add 127.80 and 57.51 together.  That will give us 185.31.  Add that to the 639, and you have your answer.  Hope this helped!

An island has some portion submerged in water. Point A on the island is at negative 7 over 3 feet from the surface of the sea. P
sashaice [31]

Answer:

1/6feet

Step-by-step explanation:

Given

Point A on the island = -7/3 feet from the sea surface

Point B on the island = -5/2 from the sea surface

The distance between the two points will be Point A - Point B

Distance between the two points = -7/3 - (-5/2)

= -7/3+5/2

Find the LCM

= {2(-7)+3(5)}/6

= -14+15/6

= 1/6

Hence the distance of the two points from the surface of the sea is 1/6feet

Hello! May Someone Kindly help me with this? its worht 13 points!
shusha [124]
So basically, to graph the points, you look at the x axis first. look at the first point. for example,(-2,4) look at the x axis and find -2. then, go up four points. do that to the rest of the points, then connect the dots, labeling the corresponding points you to A,B, and C. based off of this graph, turning it clockwise means to mirror it from the y axis. 90 degrees mean clockwise! from the new graph, bring each point 3 units down. thats it! good luck!

Suppose a population of 10 spiders doubles in size every month. How
gregori [183]

Answer:

b. 40,960

Step-by-step explanation:

There is probably some equation you could do for this but I find it simpler just to take 10 and multiply it by 2 and then keep multiplying the answers by 2 twelve times so:

10*2=20

20*2=40

40*2=80

80*2=160

160*2=320

320*2=640

640*2=1280

1280*2=2560

2560*2=5120

5120*2=10240

10240*2=20480

20480*2=40960
