Dahasolnce [82]

Answer:

34

Step-by-step explanation:

All angles of a triangle add up to 180 degrees so you would subtract from 180 with the angles you already have to get your answer. 180 - 115 - 31 = B which is 34.

NEED HELP ASAP!!!
Sergeeva-Olga [200]

Answer:

(b) P(\textrm{Event of getting a 3 in the spinner)}  =  \frac{11}{61}

Step-by-step explanation:

Let E: Event of getting a 3 in the spinner.

So, the number of favorable outcomes  =  11

Total number of outcomes = Number of times the outcomes is {1,2,3,4,5,6}

= {13 +10 +11+16+11}  = { 61}

So, the total number of outcomes = 61

\textrm{Probability of Event E}  = \frac{\textrm{Number of favorable events}}{\textrm{Total number of outcomes}}

So, here P(\textrm{Event of getting a 3 in the spinner)}  =  \frac{11}{61}

B is the midpoint

\\ \sf\longmapsto AB=\dfrac{1}{2}AC

\\ \sf\longmapsto 7x-3=\dfrac{5}{2}

\\ \sf\longmapsto 5=2(7x-3)

\\ \sf\longmapsto 5=14x-6

\\ \sf\longmapsto 14x=6+5

\\ \sf\longmapsto 14x=11

\\ \sf\longmapsto x=\dfrac{11}{14}

\\ \sf\longmapsto x=7.8

80 is earnings per day

d is number of days

The algebraic expression is 80d
