Kenny's weight is 6/7 times melvin's weight. what is the ratio of melvin's weight to the total weight of the two boys?
Answers
Answer:
Step-by-step explanation:
Let
x------> Melvin's weight
y------> Kenny's weight
we know that
-----> total weight of the two boys
Find the ratio of Melvin's weight to the total weight of the two boys
Kenny's Weight*6/7=Melvin's Weight
So, for example, if Melvin's weigh was 7...
Kenny's Weight*6/7=7
divide both sides by 6/7
Kenny Weight=6
So we can say that Melvin's weight to Kenny's weight is 7:6
The boys total weights would be...
7+6=13
So Melvin's weight over the total weight of the two boys is:
7:13

Answer:
The x-intercepts are (2+√(8/3),0) and (2-√(8/3),0)
Step-by-step explanation:
y = A(x+2)2 - 8
Since (0,4) is on the graph, 4 = 4A-8
4A = 12
A = 3
So, y = 3(x+2)2-8
To locate the x-intercepts, set y = 0 and solve for x:
0 = 3(x+2)2-8
3(x+2)2 = 8
x+2 = ±√(8/3)
x = -2 ± √(8/3)

Answer:
The cart gravitational potential energy is 117,600 Joule
Step-by-step explanation:
First lets define what a gravitational potential energy is.
A gravitational potential energy is the energy stored in an object that rise above a certain height surface.
The formula for calculating the gravitational potential energy(P.E) is m×g×h, where m is the mass of the object measured in kilograms(kg), g is the acceleration due to gravity measured in *(m/s²). It is a constant and always equal to 9.8 m/s² on the earth surface and h is the height of the object above the surface in (m).
The gravitational potential energy is measured in Joules(J).
From the question, mass(m) is given as 40 kg and the height(h) is 300m
and g=9.8m/s²
Gravitational Potential Energy(P.E) = m×g×h
=40 ×9.8 ×300
=117,600 Joules.
Therefore the cart gravitational potential energy is 117,600 Joules.
m for mass = 40 kg
g for gravitational field strength = 10 N/kg
h for height = 300m
Plug them in:
g.p.e = 40 × 10 × 300
= 120000 J
In terms of kilo joule:
1 kJ = 1000 J
so 120000 J = 120 kJ
