The top layer has 1 orange and the layer below has 4 oranges, the layer below has 9 oranges, the total number of oranges for each layer:
Layer 1 = 1 orange
Layer 2 = 4 oranges
Layer 3 = 9 oranges
Total: 14 oranges.
The number of oranges required for 10 layers can be solved using an arithmetic sequence.
A number multiplied by a power of 10 makes the decimal point move to the right as many as there is zeroes in the power of 10: for example, 1*10=10, 5.5*100 = 550.
In your case:
a) 4301 = 430.1 * 10 = 43.01 * 100 = 4.301 * 1000... more the decimal point goes backward, the more zeroes you add to the power of 10.
b) 687 = 68.7 * 10 = 0.687 * 1000 = 0.0687 * 10 000, if the decimal point goes beyond the last number, you add zeroes to the left before the decimal point.
c) Same thing here! 56 = 5.6 * 10 = 0.56 * 100, etc..
Hope this helps! ;)
Answer:
6 cars per hour
Step-by-step explanation:
The rate can be expressed several ways. One of them is "cars per hour". To find that rate, divide cars by hours:
(24 cars)/(4 hours) = 6 cars/hour
__
If 6 cars were washed in 60 minutes, another way to express the rate is ...
(60 minutes)/(6 cars) = 10 minutes/car
__
When you ask "what is the rate?", you need to be specific as to the rate you're interested in. Different expressions of the rate are useful for different purposes.
Answer:
Answer: D
Step-by-step explanation:
Let's just go through it.
No parallel sides A B C (if you believe the diagram) D F
Not regular (and no parallel sides) (if you believe the diagram) B C D F
No Lines of symmetry (that means that if you put a mirror on a line of symmetry) what you see as an image will be the same as what there is in front of the mirror. C D F
Has a reflex angle. (Just to remind you, it is an angle greater that 180 but less than 360
That lets out everybody but D.
