There's ambiguity here. Either the original expression is "5 times the square root of a" or 5 is the "index of the root."
Then "5 times square root of a" would be 5a^(1/2), or
1/2
5a
. On the other hand, if you meant 5 to be the "index of the root," then the correct result would be
1/5
a

Answer: 238.95 in²
because this is a regular pentagon
=> the area of the regular pentagon will be 5 times the area of the triangle in the picture.
we have: the area of the triangle is: (11,8.8,1)/2 = 47,79 (in²)
=> the area of the regular pentagon is 5. 47,79 = 238,95 (in²)
Step-by-step explanation:
Answer:
Darlene and Mary will be on the same page after 1 hour.
Step-by-step explanation:
Given:
Number of pages Darlene has already completed = 72
Rate at which Darlene continues working = 14 pages per hour
Number of pages Mary has already completed = 81
Rate at which Mary continues working = 5 pages per hour
To Find:
Time after which the students will be on the same page =?
Solution:
let the time after which the students will be on the same page bex X
then
After X hours, number of pages completed by Darlene will be
72 + 14(x)--------------------------------------------------(1)
After X hours, number of pages completed by Mary will be
81 + 5(x) ---------------------------------------------------(2)
Equating the equations (1) and (2)
72 + 14(x) = 81 + 5(x)
72 +14x = 81 + 5x
solving the equation,
14x - 5x = 81-72
9x= 9
x=
x=1
Answer:
5484 gallons
Step-by-step explanation:
Given that:
Delivery in 1 day = 457 dozen gallons
g = number of gallons delivered on that day
Recall :
1 dozen = 12
Therefore, the number of gallons delivered in 1 day :
457 gallons * 12 = 5484 gallons
