Nina is 64. I hope this is correct , let me know if it isn’t .
If you would like to know how much longer is Molly's jump rope, you can calculate this using the following steps:
6 1/3 feet long - 4 2/3 feet long = 6 1/3 - 4 2/3 = 19/3 - 14/3 = 5/3 = 1 2/3
The correct result would be 1 2/3 feet longer.
Given:
Area of a sector = 
Radius = 5 cm
To find:
The central angle.
Solution:
The area of a sector is:
Where, r is the radius and 
is the central angle in radians.
Putting 
in the above formula, we get
Multiply both sides by 2.
Divide both sides by 25.
Therefore, the central angle in radians is 
.
4 days later. ugh haha sorry. answer in the first ten min on time my butt
L=7+W
area=30=LW
so subsitute 7+W for length
30=(7+W)(W)
30=W²+7W
minus 30 both sides
0=W²+7W-30
factor
what 2 numbers multiply to get -30 and add to get 7
-3 and 10
0=(W-3)(W+10)
set to zero
0=W-3
3=W
0=W+10
-10=W
false, can't have a negative width
width=3in
L=7+W
L=7+3
L=10
the length is 10in
the width is 3in
