Answer:
Step-by-step explanation:
error in measurement = 480 - 469 = 11 inches
Percent error = error *100/actual length
= 11 * 100 /480 = 2.9%
Just subtract but take care of the power or else you can come up with wrong results !
so first make the power same ;
for Jupiter = 1.898× 10(27) = 18.98 × 10(26)
for Saturn = 5.68×10(26)
so now subtract = (18.98-5.68) × 10(26)
= 13.3 × 10(26)
so the answer is 13.3 ×10(26)
or, 1.33× 10(27)
For Sammie the equation would be S=3N.
If Nora (N) has 4 goldfish, you substitute N=4 into the previous equation to find out how many goldfish Sammie has.
> S= 3 x 4
= 12
The next part of the question is asking you how many goldfish do Sammie and Nora have in all. If Sammie has 12 goldfish and Nora has 4 goldfish, the equation would be 12 + 4= 16
The answer would be 16 goldfish in total.
2/14x is the right answer.
Answer:
60 sides
Step-by-step explanation:
The formula for the sum of the interior angles of a polygon with n sides is 180(n -2). The problem also tells you that each angle is 174, so the sum of the interior angles would also be 174n.
Then, you get the equation
180(n - 2) = 174n
180n - 360 = 174n
6n = 360
n = 60 sides.
