8.64 - 3.15 = $5.49 if this is what you are asking
Assume the length of the ribbon was X
after tieing the parcel , the reminder is X - 3/8 = 5/8 X
Rebecca used 1/5 of the reminder, so the remainder of the remainder is 4/5 of the remainder = (4/5) * (5/8X) = 24 cm
20/40X = 24
So X = 48 cm
Answer:
C(x) = 100 + 12x
L(x) = 275 + 10x
Step-by-step explanation:
Let x = no. of hours
C(x) = 100 + 12x
L(x) = 275 + 10x
Answer:
18
Step-by-step explanation:
as there are 12 red spheres there are 12*4 red cubes (48) add them ,60.Then 60/2 to find blue shapes ,30, then add the 2 and 3 to make 5 after that do 30/5 = 6 then multiply by 3
Given that:
mean,μ=35.6 min
std deviation,σ=10.3 min
we are required to find the value of x such that 22.96% of the 60 days have a travel time that is at least x.
using z-table, the z-score that will give us 0.2296 is:-1.99
therefore:
z-score is given by:
(x-μ)/σ
hence:
-1.99=(x-35.6)/10.3
-20.497=x-35.6
x=35.6-20.497
x=15.103
