81 if the number is higher than 5 or equal to 5 you round up
Answer:
C
Step-by-step explanation:
r=5t
r squared=25t squared
area=pi r squared
so, A(r(t))=25(pi)(t squared)
Answer:
38,200,000
Step-by-step explanation:
Put the 3 in the 8th spot to the left of the decimal point and fill in the other digits to the right of it.
38,200,000
__
The first spot immediately to the left of the decimal point has a place value of 10^0, so the location with a place value of 10^7 is the 8th spot left of the decimal point. You should be able to get the idea from the attached.
__
If you put your calculator in the appropriate display mode, it should show you the number in this form.
Answer:
You have completed only half in a 1/4 of a day
Step-by-step explanation:
think of it this way
lets say in half a day e.g at 12pm you finish the report
half of 12 is 6
so that would be a 1/4 of the day
100%=24 hours=whole day
50%=12 hours=half a day
25%=6 hours = quarter of a day
25% = 1/4
i hope this helps
Answer:
Angles KNL and JNM are vertical angles so they are equal so
10y - 12 = 8y + 4
2y = 16
y = 8
So angle KNL = 10y - 12 = 10(8) - 12 = 80 - 12 = 68�
and, as a check
Angle JNM = 8y + 4 = 8(8) + 4 = 64 + 4 = 68�
