-0,046875
Step-by-step explanation:

Answer:
FV=PV(1−d)^n
FV = 290(1-.132)^14
FV = 290(.868)^14
FV = 39.96 g
Step-by-step explanation:
6.5c + 9.7a = 1721.4
a = 4c
6.5c + 9.7(4c) = 1721.4
6.5c + 38.8c = 1721.4
45.3c = 1721.4
c = 1721.4 / 45.3
c = 38...so there were 38 childrens' tickets <==
and 152 adult tickets
Answer:
The area of the whole field is 54400yd^2
Step-by-step explanation:
says that I add 10 yards in each zone, that means that 10 yards is added twice at 1000 yards
1000yd + 2*10yd = 1020yd
we have to know that one yard equals 3 feet
so to have the length in feet we only multiply it by 3
1020 * 3 = 3060ft
Now that we know the length and width of the court, we can calculate the area by multiplying them
a = b * h
a = 3060ft * 160ft
a = 489600 ft^2
the result is in square feet
if we want it in square yards we just have to divide 2 times by 3
489600/(3*3) = 54400yd^2
Answer:
50 gallons of red
30 gallons of blue
Step-by-step explanation:
5 parts of the whole must be red, 3 parts of the whole must be blue, and there are 5+3=8 parts in total.
therefore, 1 part = 80/8 = 10 gallons
red : 5 parts
5×10 = 50 gallons
blue : 3 parts
3×10 = 30 gallons
