<h3>
Answer: 140 degrees</h3>
==================================================
Explanation:
See the diagram below.
We start with triangle PQR with the given angles mentioned. Then you extend out segment QR to form line QR. It goes off infinitely in both directions.
The exterior angle x adds to the interior angle Q = 40 to get 180
x+40 = 180
x+40-40 = 180-40 ... subtract 40 from both sides
x = 140
The exterior angle is 140 degrees
which means the sum of the 100 numbers must be
Answer:
0.111111...
Step-by-step explanation:
Hi,
this function is stating that for any x the f is 9(3)^x.
SO if x was -4 it would be 9(3)^-4
Following order of operations we calculate the exponent first.
the answer is 0.1111111...
Answer:
4(2x+3)
Step-by-step explanation:
8x+12
4(2x+3)
----------------
Note that 8x+12=4(2x+3),
because we factored out 4.
Sal's answer is wrong because even though 2(4x+6)=8x+12,
but the answer 4(2x+3) is more reasonable,
because our goal is to find the largest number when factoring an expression.
Answer:
C
Step-by-step explanation:
Longest practice is 2 1/2 hours long
Shortest is 1 1/4 hours long
For difference, subtract 1 1/4 from 2 1/2
Convert mixed to improper fractions
(2*2+1)/2 - (1*4+1)/4
5/2 - 5/4
10/4 - 5/4 = 5/4
Change back to mixed fraction
1 1/4
