If you walk 3 kilometers in 30 minutes, what is your average speed in kilometers per hour?
Answer:
If you walk 3 kilometers in 30 minutes your average speed is 6 kilometers per hour.
Therefore, the avearge speed in kilometers per hour is [tex]0.1[/tex] kilometer per hour.
What is the speed?
The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.
Here given that,
Here, you walk [tex]3[/tex] kilometers in [tex]30[/tex] minutes. So the average speed is :-
Speed = Distance/ Time
Distance is [tex]3km[/tex] and the time is [tex]30[/tex] minutes so,

Megan wants to give each guest at her birthday party three mini-
cans of Play-Doh. The cans are sold in bags of nine for $2.86. If there
are thirty-six guests at her party, how much will it cost to give three
mini-cans of Play-Doh to each guest?
Number of guests to be invited in the birthday party = 36
Megan wants to given 3 cans of Pay-Doh to each guest.
Therefore, number of cans to be given = 3 × 36 = 108
Since, cans are sold in the pack of 9, number of packs required = [tex]\frac{108}{9}[/tex]
= 12
Since, cost of each pack of cans = $2.86
Therefore, total cost of 12 packs = 12 × 2.86

Write an equation in which the quadratic expression 2x^(2)-2x-12equals 0. Show the expression in factored form and explain what your solutions mean for the equation. Show your work.
Answer:
Answer:
Begin by factoring 2 out of 2x^2 - 2x - 12 equals 0:
2(x^2 - x - 6) = 0
2(x - 3)(x + 2) = 0. 2 is never zero, but x-3 and x+2 can each be set = to 0:
This results in x = 3 and x = -2. The equation is true for these two x-values.
