Answer:10%= 310
5%= 155
15%=465
Step-by-step explanation: Solution for what is 15% of 3100
3100/x=100/15
(3100/x)*x=(100/15)*x - we multiply both sides of the equation by x
3100=6.66666666667*x - we divide both sides of the equation by (6.66666666667) to get x
3100/6.66666666667=x
465=x
x=465
First you have to find the area of each polygon by adding each number on all the sides then if this helps put the eqaule number of the polygon by it then do the same with the other polygon and if there the same you put eaquvilant or just circle both of them
To solve this problem we can find the area of the whole rectangle, then find the area of the smaller white rectangle inside the whole rectangle. Lastly, we can subtract the area of the smaller rectangle from the area of the whole rectangle which leaves us with the area of the shaded region.
Area of whole rectangle = length x width
= (3x + 6) (2x + 4)
= 6x squared + 24x + 24
Area of small rectangle = length x width
= (x-3) (x - 1)
= x squared - 4x + 3
Area of shaded region = area of whole rectangle - area of small rectangle
= 6x squared + 24x + 24 - x squared + 4x - 3
= 5x squared + 28x + 21
Ayy you got it right thank you very much your
Answer:
12 cm
Step-by-step explanation:
To calculate the length of a spring with a 2 kg load, compare the displacement of a 1 kg load and adjust accordingly.
When a 1 kg load is suspended from the spring, the spring which is 6 cm stretches to 9 cm. This is 3 cm longer due to the weight. If you attach a weight which is twice as much then the displacement will be twice as much. Instead of stretching an additional 3 cm, it will stretch 2*3 = 6 cm. Add this to the length of the spring and it stretches in total 6 + 6 = 12 cm.
