In this question, it is given that
Walter wants computer software that cost $129. He has $57 saved.
he saves a maximum of $15 a week, the following inequality can be used to find how many weeks it will take Walter to save enough money to buy the software.
And we have to solve this inequality for x.
First we subtract 57 to both sides. And on doing so , we will get
Dividing both sides by 15.
\
Correct option is A.
Answer:
the probability to select both marbles to be red is 36% round up to the nearest whole number.
Step-by-step explanation:
He could have had 3,6,9,12,15,,18,21,24,27,30 etc....
You need to find the acceleration once the rope starts acting.
For that, first you need the velocity, V, when Karen ends the 2.0 m free fall
V^2 = Vo^2 + 2gd = 0^2 + 2* 9.81m/s^2 * 2.0 m = 39.24 m^2 / s^2 => V = 6.26 m/s
From that point, the rope starts acting with a net force that produces a constant acceleration, modeled as per these values and equation:
Vo = 6.26m/s
Vf = 0
Vf^2 = Vo^2 + 2ad => a = [Vf^2 - Vo^2] / 2d = [0^2 - (6.26 m/s)2 ] /2(1m) = -19.62 m/s^2
That acceleration is due to the difference of the force applied by the rope - the weight of Karen:
Weight of Karen: mg
Weight of karen - Force of the rope = Net force = ma
mg - Force of the rope = ma
Force of the rope = mg - ma = m(g -a) = m [9.81m/s^2 - (-19.62m/s^2) ]= 29.43m
To express it as a multiple of her weight, divide it by her weight (mg = 9.81m) =>
29.43m / 9.81m = 3.0
Answer: 3.0 times.
Answer:
C
Step-by-step explanation:
Because if you have 75 baskets of 30 then you have to multiply 75x30 it is the same thing with 50x45. Hope this helps
