25A2B is a 5-digit number. If the number is divisible by 5 and 9, find all the possible values of A and B. Explain also.
3241004551 [841]

Answer:

25020, 25920, 25425

Step-by-step explanation:

To find if our number is divisible by 5 the number must end with 0 or 5, divisibility by 9 is if sum of all numbers in number is divisible by 9,

We know B must end with 0 or 5

1. Case 25A20 sum of that number is 9 so if we pick 0 as A we have first number because 9/9=1

We can put A as 9 because 18/9=2

2. Case B = 0, sum is 14 so we need pick A as 4 to get 18.

If sin theta = -(sqrt(3))/2 and pi < theta < (3pi)/2, what are the values of cos theta and tan theta?
Gwar [14]

For \pi, we expect \cos\theta. Then recalling that \sin^2\theta+\cos^2\theta=1, we have

\cos\theta=-\sqrt{1-\sin^2\theta}=-\dfrac12

Then by definition of tangent,

\tan\theta=\dfrac{\sin\theta}{\cos\theta}=\dfrac{-\frac{\sqrt3}2}{-\frac12}=\sqrt3

Answer:

Emilia bought 28 sweets

Step-by-step explanation:

now they have 65, but before they had 65-15+10 because earlier, zakiah had ten more sweets than now and Emilia had 15 less, so basically, if you wanna calculate number of sweets they had earlier, you have to make minus from plus and in reverse too.

65-15+10=60 and now just do that simply ratio

E:Z=7:8

E+Z=7x+8x

60=15x

4=x

7x=28=Emilia

8x=32=Zakiah

Accuracy test:

(28+15)+(32-10)=65

28 is 4•7 and 32 is 4•8
