ANSWER:3.6
EXPLAINATION:
since a diameter is the total length from one side to the other and a radius is just to the middle of a circle. to get the diameter yoo would have to divide 7.2÷2=3.6
IF YOU LIKE MY ANSWER I WOULD APPRECIATE A BRAINLIEST. THANK YOU
Answer:
Step-by-step explanation:
The variables are defined, so we only need to express the given relations. The total of the two quantities is 14.
x + y = 14
The sum of costs is $72. Totts are $8 each, so x of them will cost 8x. Elentines are $3 each, so y of them will cost 3y.
8x +3y = 72
Question
Find the least common multiple of 8 and 15.
Answer= 120
1 feet is 12 inches so 40 feets is 480 inches
Real locomotive is 480/16=30 times wider then the model
And then a window on the real locomotive is 30 times wider then the model.
Answer:
The exponential growth model is given by this general expression:

And the exponential model decay model is given by:

Where a the initial amount r the growth factor of rate anf t the time.
The reason with we need to add 1+r in the base of the model is because each period of time
we have an increase of the initial amount by a factor of (1+r) so after n periods we will have (1+r)^n times the initial amount.
Step-by-step explanation:
In general an exponential model is given by this formula:

Where:
a = the constant, b = the base and x x the exponent.
