Paul must get 13 since Peter gets more more than Jane so Jane would get 7 and then peter would get 12
Answer:
Step-by-step explanation:
Let x represent the length of the rectangle. The the width is (4x+2) and the area is ...
x(4x+2) = 342
2x² +x - 171 = 0 . . . . . divide by 2, rearrange to standard form
(2x +19)(x -9) = 0 . . . factor
x = -19/2 or +9 . . . . . the length is the positive solution: 9
(4x+2) = 4(9) +2 = 38 . . . . find the width from the length
The length of the rectangle is 9 meters. The width is 38 meters.
Answer:
The correct answer should be D.
Step-by-step explanation:
X = 100 : 10 = 10
5x : 4x : x
50 : 40 : 10
To solve the problem shown in the figure attached in the exercise, you must follow the proccedure shown below:
1. You have that the<span> formula for calculate the velocity (v) in feet per second (ft/s), of an object that has fallen h feet is:
v=</span>√(64h)
<span>
2. The problem shown above asks for the velocity of an object that has fallen 23 feet. Therefore, to solve this exercise you only have to susbtitute h=23 feet into the formula for calculate the velocity (v), as below:
v=</span>√(64h)
h=23 feet
v=√(64)(23)
v=√(1472)
v=8√23
v=38.37 feet per second
3. Therefore, as you can see, the correct answer is the second option, which is: 38.37 feet per second
