Answer:

10=40

50=30

Step-by-step explanation:

Suppose the number of 10 paise coins =x

∴ the number of 50 paise coins =70−x

Now, value of 10 paise coins = Rs.  

10 x  and value of 50 paise coins = Rs.   2 70−x

Total value of coins =   10 x +  2 70−x

​∴  10 x  +  2 70−x  =19

Multiplying both sides by 10, (LCM of 10,2=10), we get  

x+5(70−x)=19×10    

x+350−5x=190

−4x=−160

−4 −4x  =  −4 −160

​∴x=40

∴ number of 10 paise coins =40  

Number of 50 paise coins =70−40=30.

When a number is a multiple of 6 what are possible values of the ones digit
umka21 [38]
6,2,8,4,and 0 are the only possible value of the ones digit, because 
6*1=6, last digit is 6
6*2=12, last digit is 2
6*3=18, last digit is 8
6*4=24, last digit is 4
6*5=30, last digit is 0
6*6=36, last digit is 6
and the whole cycle goes over again.

A triangle has an angle that measures 25. The other two angles are in a ratio of 11:20. What are the measures of those two angle
frozen [14]

Answer:

The measures of the two angles are 55 and 100 degrees.

Step-by-step explanation:

The three interior angles of a triangle always add up to 180.

So if one angle is 25 degrees

180 - 25 = 155

The two other angles must add up to 155.

If the ratio is 11:20

That means there are 31 equal parts between the two angles

So 155/31 =5

Whic means

11 x 5 = 55

20 x 5 = 100

The two missing angles are 55 and 100 degrees.

Hope this explanation helped you!
