Answer:
You have 43 nickles and 23 pennies
Step-by-step explanation:
43 x 5 = 2.15
you have 2.38 total in 66 coins
so 2.38 - 2.15 = 0.23
that will leave you with 23 pennies
23 pennies plus 43 nickles = 2.38
0.23 + 2.15 = 2.38
The answer is choice C
------------------------------------------------
You start off with the first term being a1 = 3
Then you add on 3 to get to 6 as the second term
The next thing to do is add on -3, which is the same as subtracting 3, to get back to 3 once more.
This pattern continues on forever. To ensure you add on either +3 or -3 to the previous term, we add on the general term 3*(-1)^n
Overall, the nth term is found by a(n) = a(n-1) + 3*(-1)^n, which is what choice C shows. I'm assuming your teacher meant to write 3(-1)^n instead of 3(-1)n
Answer:
240
Step-by-step explanation:
So let the first side be x. So the next side is 3x and the last side is (3x +60) . Add all 3 sides and set equal to 480. So x + 3x + (3x +60)= 480. Now do the Algebra. So 7x + 60 = 480. Subtracting 60 we get 7x = 420 so x= 60. You are asked to ffg ind the length of the longest side so 3(60) + 60 = 240.
Answer:
V= πr²h
V= 72π
V= 226.2
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a cylinder
Given data
Radius r of cylinder 3
Height h of cylinder 8
We know that the volume of a cylinder is given as
V= πr²h
Substituting our given data we have
V= π3²*8
V= π9*8
V= 72π
V= 226.2
Make hours to seconds to match meters
19.6*3600=70560 seconds
And is dropped from a height of 15.4 meters then the velocity will be
15.4m/70560s = 0.0002182539m/s
