Answer:
Kira has 40 Jelly beans
Step-by-step explanation:
Morgan and Kira have a number of jelly beans in a ratio 5:3.
The ratio is
Morgan : Kira
5:3
The total proportion is= 5 + 3 = 8
Total number of Jelly beans that they have together is = 64 jelly beans
Hence, the number of Jellybeans that Kira has is calculated as:
5/8 × 64 jelly beans
= 40 jelly beans.
Kira has 40 Jelly beans
Answer:
Approximately
, assuming that
.
Step-by-step explanation:
When the force
is constant, moving by
in the direction of the force would do a work of
.
However, in this example, as an increasing portion of the chain gets lifted up, the force lifting the chain would increase in size. Hence, apply the integral form of this equation.
Let
denote the force required to lift the chain when the height above the ground is
meters. At that moment, exactly
of the chain would be above the ground. The mass of that much of the chain would be
the mass of the whole chain.
.
Integrate with respect to
:
.
In other words, it would take approximately
of energy to raise one end of the chain to that height of
.
Answer: wow, that's a hard one, well the answer is 2
Step-by-step explanation: logic
2 1/7 + 3/7 (3x-5)= - 4
2 1/7 + (9/7)x - 15/7 = - 4
15/7 + (9/7)x - 15/7 = - 4
(9/7)x = - 4
x = - 4 * 7/9 = - 28/9 = - 3 1/9
Answer is - 28/9 or - 3 1/9.
