Answer:
36 minutes.
Step-by-step explanation:
Piggly takes 6 minutes and Wiggly takes 5 minutes. Therefore Wiggly is travelling one minute slower.
If we just think about the first lap to start, and break it up into minute sections (like in the diagram attached), we can think about each pigs placement on the diagram for each lap.
At the end of the first lap, Piggly will have reached the end of the 6th minute section and will be back at the start/finish. Wiggly will only be at the end of the 5th minute section.
For the second lap, Piggly will again end up back at the start/finish, but Wiggly, having started his lap one section behind (at the end of the 5th section) will now end up even further behind (at the end of the 4th section).
Go ahead and count it out. Every lap he only covers 5 section, so every lap he falls one section further behind.
After six laps he will finish back at the start, at the same time as Piggly (but Piggly will be a lap ahead of him. Our sections have 6 minutes in each, and 6 laps are completed.
6 x 6 = 36 minutes
The answer will be A
you will substitute
There are 30 treasures.
80% are found:
80% of 30 = 0.8 x 30 = 24
Bella found 24 of them
30 - 24 = 6
There are 6 more left to find
If x represents the number of children under three years, which equation can be used to find the value of x, where C represents the total amount of money collected from tickets that day is <span>(40 + x)36 + (92 − (40 + x)) ⋅ 48 = C </span>
Answer:
x= 5.55 and 0.45
Step-by-step explanation:
Quadratic Equation = (-b±√b²-4(a)(c))÷2(a)
Get equation = to 0 by subtracting the 3 on the right side of the = sign
2x² - 12x + 5
Identify the variables
a=2
b=-12
c=5
Put them into the quadratic equation
(-(-12)± √-12² - 4(2)(5))÷2(2)
Simplify
(12 ±√144 - 40)÷4
(12±√104)÷4
Now split into 2 equations (one with addition one with subtraction) because of the ± then continue simplifying
(12 - √104)÷4 (12 + √104)÷4
(12 - 10.198039)/4 (12 + 10.198039)/4
5.54950975 0.45049025
Round
5.55 0.45
