Answer:
y=5 does not equal 2y=15
Step-by-step explanation:
If you plug y into the equation we get 2(5)=15
The next step is to multiply 2*5, which equals 10
10≠15
<u>35.12 miles </u><u>is the total number of minutes that it took krissy to run these three miles.</u>
What is a simple definition of time?
The measured or measurable period during which an action, process, or condition exists or continues : duration. b : a nonspatial continuum that is measured in terms of events which succeed one another from past through present to future.
Krissy ran three miles one morning she ran the first mile in time 1 = 11.74
Krissy ran three miles one morning she ran the first mile in time 2 = 11.26
Krissy ran three miles one morning she ran the first mile in time 3 = 12.12
To get total time , we have to add all the time 1,2,3
Total time = Time1 + Time2 + Time3
= 11.74 + 11.26 + 12.12
Total Time = 35.12 <u>miles</u>

Answer:
It is a Cuboid
Area of the base = 12x9
Area of the top = 12x9
Area of the right lateral faces = 9x7
Area of the left lateral faces = 9x7
Area of the front face = 12x7
Area of the rear face = 12x7
Total surface area is the sum of above (please do it yourself)
The volume = base surface Area x height
= 12x9x7 = 756
Be reminded to put in the right unit for Area and volumn
Answer:
Step-by-step explanation:
There are solutions on the internet. Just google it. We are not allowed to give you a link, but if you put in "solutions to rubic's cube", the first one that comes up is pretty good.
