Answer:
14
Step-by-step explanation:
Substitute the given values for a and b into the expression and evaluate
a + b = 43 + (- 29) = 43 - 29 = 14
Answer:
(40,0)
Step-by-step explanation:
A rotation of 270 degrees° counterclockwise about the origin has the rule

A ferris wheel is drawn on a coordinate plane so that the first car is located at the point (0,40).
According to the given rule, the image point after a rotation of 270 degrees° counterclockwise about the origin have the coordinates (40,0) (see attached diagram for details).
Answer:
you multiply all of those answers
Step-by-step explanation:
See the attached figure to understand the problem
we know that
tan 42°=1950/BO---------> BO=1950/tan 42°-------> BO=2165.69 ft
tan 39.5°=1950/AO---------> AO=1950/tan 39.5°-------> AO=2365.54 ft
AB=AO-BO--------> AB=2365.54 ft-2165.69 ft-------> AB=199.85 ft
the answer is
The runners are 199.85 feet apart
First, what letter can it be at the beginning?
English Alphabet has 26 letters, so we have 26 possibilities
26*
then it can be any of 10 digits
26*10=260
then any of the remaining 9 digits:
26*10*9
then any of the remaining 8 and 7 digits:
26*10*9*8*7=131040
so the solution is: 131040 possible combinations!
