X/5 = 8/9
this is a proportion, so we cross multiply
(9)(x) = (5)(8)
9x = 40
x = 40/9 or 4 4/9

The sides of a backgammon die are marked with numbers 2,4,8,16,32 and 64. Describe an outcome that has a probability of 2/3
Cloud [144]
The probability 2/3 means that there are 2 events we are interested in (which probability to happen we calculate) and there are 3 total events that may happen.
The probability 2/3 is equal to the probability 2/3*2/2=4/6.
An possible outcome would be : The probability that the side of the backgammon can be divided with 8 (there are 4 possibilities: 8, 16, 2 and 64).

Can someone help me with this question "Given the triangle below, what is m (angle) < B, rounded to the nearest tenth?
JulsSmile [24]
The answer
the sum of the angles in a triangle is always 180°
m < B + m < A + m < C = 180°,  
let's find m < B, 
by applying sinus rule 
 14/sinB=10/sinC, so sinB= 10xsinB = 14 x sinC and therefore, 
sinB=( 14/10 )sinC =7/2 sin 36° =0.82, so arcsinB=55.08°
the answer is C 55.4°

Step-by-step explanation:

2(2x - 1) + 7 < 13

4x - 2 + 7 < 1

4x + 5 < 13

4x < 8

x < 2

-2x + 5 ≤ -10

-2x ≤ -10 - 5

-2x ≤ -15

x ≤ -15 / -2

x ≤ 7.5
