Step-by-step explanation:
Let p and h represent pay and hours worked respectively,
p = kh
k = p/h = 148.5/18 = 8.25
p= 8.25h
90.75 = 8.25h
h = 11 hours.
Hope it helps! :)
Remember that straight lines are 180°. For #1 angle 1 would be 40°, since 140°+40°=180°
Answer:
In ∆ABD and ∆ACD
<BAD =<CAD ( each are half of <A )
<D=<D ( each equal to 90°)
AD = AD ( common)
So ∆ ABD is congruent to ∆ ACD.
Then AB =AC (by C.P.C.T)
Hence,∆ABC is an iso - sceles triangle.
Answer:
The multiplicative rate of change is 3
Step-by-step explanation:
The given graph passes through the points:

The multiplicative rate of change is the factor that multiplies each y-value to give the subsequent y-values.
We can find that factor by dividing a y-value by the previous y-value of any two consecutive y-value.
The multiplicative rate of change is
