Answer:
The number is 5
Step-by-step explanation:
6+3n = 5n-4
Subtract 3n from each side
6+3n-3n = 5n-3n-4
6 = 2n-4
Add 4 to each side
6+4 = 2n-4+4
10= 2n
Divide by 2
10/2 =2n/2
5=n
Answer:
t=4.19 seconds
Step-by-step explanation:
Distance varies directly with the square of the time of the fall
It means,
D=kt^2
18ft in 2 seconds
D=kt^2
18=k*2^2
18=4k
k=18/4
=9/2
k=9/2
D=kt^2
D=79feet
79=9/2t^2
t^2=79÷9/2
t^2=79×2/9
=158/9
t=√158/√9
t=12.57/3
t=4.19 seconds
Answer:
The ratio can be 16:14 whose simplest form is 8/7

To solve this problem you must apply the proccedure shown below:
1. You need to apply the Pythagorean Theorem:
Where <em>c</em> is the hypotenuse and the legs are<em> a</em> and <em>b.</em>
2. Now, you must substitute the values given in the problem above and solve for <em>b</em>:
Therefore, the answer is: The value of <em>b</em> is 6.92
