The answer would be a. Yes, the student’s answer is
reasonable.
In the problem, it states that Cindy rode her bike for an
hour and ran for an hour. Without the
presence of the comma between rode her bike for an hour, and ran for an hour,
this just means that Cindy only rode her bike and ran it for an hour.
The sentence can be written as Cindy rode her bike and ran
for an hour. So, this gives an answer
that Cindy only exercise for an hour.
Star at -20 and go back by -5 on the number line
Answer:
The last one.
Step-by-step explanation:
The solutions with the horizontal lines are wrong because then h(x) would be -1 and 1 respectively.
The subtlety is in the open or closed dot. x ≥ -1 means that -1 is included, which is drawn as a closed dot. x < -1 means that -1 is excluded, which is drawn as an open dot.
Hence the last graph is the correct one.
Answer:
<em>B. 86 degrees</em>
Step-by-step explanation:
Given the following angles:
m∠NOQ = 110
m∠NOP = 24
Using the addition postulate:
m∠NOQ = m∠NOP + m∠POQ
110 = 24 + m∠POQ
m∠POQ = 110 - 24
m∠POQ = 86
<em>Hence the measure of m∠POQ is 86 degrees</em>
