If she drives 318.4 km for 4 hours, then if we divide 318.4 by 4 we get 79.6 km per hour.
79.5km per hour x 5.5 hours
=437.8 km
Answer:
107 :)
Step-by-step explanation:
In total there are 53+8+155+17+145+10+98+2=488 physicians of aerospace medicine. 45-54 year-old males account for 145/488 of this population, so they should account for that fraction of the central angle of the circle graph also. Since there are 360 degrees in the central angle to divide up among the groups, the 45-54 year-old male group should get 145/488 x 360 which rounds to about 107 degrees.
3/5 of 60
= 60 divided by 5
= 12
12 x 3
= 36
Answer:
Length in feet is equal to 
, where P is the perimeter
Step-by-step explanation:
Let the width (W) of the yard be "X"
Then the length(L) of the yard will be
The perimeter of the yard will be equal to the sum of twice the length and width of the yard
Thus,
Substituting the given values in above equation, we get -
Thus, width in terms of perimeter is equal to
Length in feet is equal to
3(x^2 + 6x + 5) = 0
3(x^2 + 6x + 9 + 5 - 9) = 0
3(x + 3)^2 + 3(-4) = 0
3(x + 3)^2 - 12 = 0
3(x + 3)^2 = 12
(x + 3)^2 = 4
x + 3 = sqrt(4)
x = -3 + or - 2
x = -3 + 2 or -3 - 2
x = -1 or -5
The correct answer option is option c.
