Answer:
Step-by-step explanation:
A polynomial function involves only non-negative integer powers or only positive integer exponents of a variable in an equation.
Solve for the two velocities:
with the current = 48/6 = 8 mph
against the current = 48/8 = 6 mph
bv= boat velocity in still water
cv = current velocity
A) bv -cv = 6mph
B) bv + cv = 8mph
Adding both equations
2 * bv = 14 mph
boat velocity = 7 mph
current velocity = 1 mph

<span>To find this answer, multiply the numerators across: (8 x 6 x 1) = 48, and the denominators in the same fashion: (15 x 5 x 3) = 225. This gives a non-reduced fraction of 48/225, which, when reduced by 3s, gives a product of 16/75.</span>
Answer:
im leaning towards 200
Step-by-step explanation:
If we assume that the lines BC and the ilne that pint A is on are paralell since they didn't specify
remember at interior angles are congruent
also oppiotie angles are congruent
therefor angle x is congruent to 3x-70
so solve
x=3x-70
add 70 to both sides
70+x=3x
subtract x from both sides
70=2x
divide by 2
35=x
angle abc needs to be found
since that euals angle x
the asnwer is 35 degrees
