0.7845 and 0.07845 because you keep moving the decimal to the left.

How to solve 2(x+y)^2-9(x+y)-5

Aliun [14]

Answer:

2(x + y)² - 9( x + y ) -5 = 0

⇒2(x + y)² - 10 (x+y) +1(x+y) -5 = 0

⇒2(x+y)(x + y - 5 ) + 1(x + y -5 ) = 0

taking (x + y -5 ) common ,

⇒(x + y -5 )[2(x + y) + 1] =0

⇒(x + y -5)(2x + 2y +1) =0

hope , you got this

Given: Measure of arc AB = measure of arc BC,

emmasim [6.3K]

9514 1404 393

Answer:

100°

Step-by-step explanation:

The relevant relation for angle x is ...

x = (AB +DE)/2

and for angle y, it is ...

y =(AC -DE)/2

Using the second relation to write an expression for DE, we have ...

DE = AC -2y

In the first equation, this lets us write ...

x = (AB +(AC -2y))/2 = (AB +(2AB -2y))/2

2x = 3AB-2y . . . . . . . . . . . . . . multiply by 2

(2x +2y)/3 = AB = AC/2 . . . . . add 2y; divide by 3

AC = (4/3)(x +y) = (4/3)(60° +15°) . . . . multiply by 2, substitute known values

AC = 100°

The table below shows all of the possible outcomes for rolling two six sided number cubes what is the probability of rolling an

Vanyuwa [196]

<u>Answer:</u>

The probability of rolling an even number first and an odd number second is $\frac{1}{4}$

<u>Solution: </u>

As two cubes are 6 sided, the total number of possibilities are $(6\times6) = 36$

Now in those possibilities the first number will be even and the second number will be odd. If we check the table, such pairs are,

(2,1), (2,3), (2,5), (4,1), (4,3), (4,5), (6,1), (6,3), (6,5)

So, we can see we have total 9 set with the combination of first number even and second number odd. So, the probability of rolling with this combination will be $\bold\frac{9}{36}=\frac{1}{4}\bold$
