hello :)
so the intial temperature was:
-10
and if it dropped 24 then this is the equation you want to solve
-10-24
so the new temperature would be
-34 degrees
hope this helped!
Answer:
2839.16
Step-by-step explanation:
119.92(m)+81=C(t)
119.92(23)+81=C(t)
2839.16=C(t)
Answer:
19 points
Step-by-step explanation:
convert points to percents:
20 points = 100%
19 points = 95%
18 points = 90%
17 points = 85%
percent-wise, her average prior to another quiz is 92.5
so if she wants to keep to maintain that average she must get 18 1/2 points; if teacher doesn't award partial credit then she needs to get a full 19 points
For 6 hours charges $330
for 9 hours charges x
---------------------------------
x = 9*330/6 = 495 so choice C. is right
Answer:
Step-by-step explanation:
Since the segment EF appears tangent to the circle, we are assuming that it it is actually tangent.
This assumption gives us a right triangle with base (because it the radius of the circle), a perpendicular of , and a hypotenuse of ; therefore, from the Pythagorean theorem we have
.
Upon expanding the expression on the right side, we get
.
Subtract from both sides:
,
and solve for
