Xian and his cousin kai both collect stamps. xian has 64 stamps, and kai has 68 stamps. the boys recently joined different stamp-collecting clubs. xian's club will send him 20 new stamps per month. kai's club will send him 16 new stamps per month. after how many months will xian and kai have the same number of stamps? how many stamps will each have? after months xian and his cousin will have stamps each.

After one month, Xian and his cousin will have 84 stamps each.

Step-by-step explanation:

Let x represent number of months.

We have been given that Xian's club will send him 20 new stamps per month. Number of stamps that Xian would have after x months would be .

Total number of stamps that Xian would have after x months would be .

We are also told that Kai's club will send him 16 new stamps per month. Number of stamps that Kai would have after x months would be .

Total number of stamps that Kai would have after x months would be .

Now, we will equate both expressions and solve for x.

Therefore, after 1 month Xian and Kai will have same stamps.

Therefore, after one month, Xian and his cousin will have 84 stamps each.

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
