Hello!
If y varies jointly with x and z, it'll mean that x and z are being multiplied by a factor "k", to equal y.
To give you a visual, this is what I mean.
That means we'll want to find 
with the first point we're given: 
Which means our equation is:
Now, let's plug in the 
and 
from the other point to find 
.
Hope this helps!
The answer for the question is 8.33
Answer:
Part A: Triangles GCB and PBE
Part B: They're similar because they have the same internal angles.
Part C:
250/400 = BE/450
112500/400 = BE
BE = 281.25 ft
250/400 = PE/350
87500/400 = PE
PE = 218.75 ft
Answer:
The answer is B
Step-by-step explanation:
b.
$26.83
D the typical ostrich runs at a speed of about 36 mph
U work this out by adding all number together then diving by number of results
