Answer:
h(2) = 90 means that the value of function h(x) evaluated at x = 2 is 90.
Answer:
use the symmetric and transitive properties of congruence
Step-by-step explanation:
(1) ∠ABC ≅ ∠DEF and ∠GHI ≅ ∠DEF; given
(2) ∠DEF ≅ ∠GHI; symmetric property of congruence
(3) ∠ABC ≅ ∠GHI; transitive property of congruence (QED)
_____
<em>Additional comment</em>
The transitive property says if A≅B and B≅C, then A≅C. We used the symmetric property to swap sides of the congruence symbol with DEF and GHI to put the statement in the form to match the transitive property.
__
You will note we used the form ...
(statement number) statement; reason
with statement and reason separated by a semicolon.
Answer:
number of cards in a house hold and number of siblings
Step-by-step explanation:
The answer is <span>The liquid must be in the cooler fewer than 10 minutes.
</span>
Let:
m - the number of minutes the liquid is in the cooler.
a - the starting temperature
The function is:
f(m) = a - 3 * m (Since the temperature decreases by 3°F each minute m, it has a negative sign)
Let:
m - <span>the number of minutes the liquid is in the cooler.
a - the starting temperature
</span>a = 90<span>°F
</span>
<span>The temperature of a liquid must stay above 60°F:
f(m) > 60
Thus:
</span>f(m) = a - 3 * m
f(m) > 60
a - 3 * m > 60
90 - 3m > 60
90 - 60 > 3m
30 > 3 m
30/3 > m
10 > m
Or m < 10. So the correct answer is The liquid must be in the cooler fewer than 10 minutes.
