Natalia is drawing a rectangle. she wants the width to be at least 10 inches and the perimeter to be no more than 72 inches. a.) write a system of inequalities that can be used to solve this problem. b.) give a possible length and width for the rectangle. c.) give a length and width that cannot be used for the rectangle.

A) and

B) w=8 l=28

C) w=11 l=39 does not work

Step-by-step explanation:

An inequality is an equation that has a solution set or many possibilities for solutions. You write it with an inequality sign like.

A) The width must be at least 10 which means it must be equal o 10 or greater.

The perimeter has the formula for a rectangle of 2l+2w=P. If the perimeter is no more than 72, then it is equal to 72 or less than it.

B) The width could be 8 and the length could be 28 since 2*8+2*28 = 72

C) The width cannot be 11 and the length 39 cince 2*11 + 2*29 = 100.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
