It would spin 116.55 times in 3 1/2 minutes.
Answer:
1130.4 if rounded its 1330.5
i think thats the answer :3
Step-by-step explanation:
Answer:
15 sqrt(2) =c
Step-by-step explanation:
We can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
The legs are 15 and the hypotenuse is the diagonal
15^2 + 15^2 = c^2
2 * 15^2 = c^2
Take the square root of each side
sqrt(2 * 15^2 )=sqrt( c^2)
sqrt(2) sqrt(15^2) = c
15 sqrt(2) =c
Let's recall that I = Prt
so... hmm we're assuming here, it doesn't say there, but this is for 1 year period.
ok... so... let's use two quantities for such interest, say "a" is the Interest for the Principal of 6000, and let's use "b" is the Interest for the Principal of 13000.
now, we know that, whatever the interest amount of "a" is, is 220
less than whatever "b" is.
we know what "b" is,
b = 130(r-1), and 220 less than that is just b - 220, or
130(r-1) - 220.
