Answer:
$48
Step-by-step explanation:
1. multiply the original price (60) by the percent off (20% or 0.20)
60 * .20 = 12 (the discount)
2. subtract the discount (12) from the origianl price (60)
60-12 = 48
To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.
Answer:
b = long city island (l) + 10
Step-by-step explanation:
i'm not good at ALL at writing equations, sorry. i'm also not good at showing my work so i'm not sure if this'll help, but i hope you get an A on whatever assignment you're doing!! xo
Answer:
P=n*s
Step-by-step explanation:
n is the number of sides and s is the length of any one side.
The images to solve this problem is in the attachment.
Answer:
= 671.0 N;
= 300 N
Step-by-step explanation: From the image in the attachment and knowing that the box is in equilibrium, i.e., the "sum" of all the forces is 0, it is possible to conclude that:
=
and
= 
Using trigonometry, shown in the second attachment, the values for each force are:
sin 20° = 
=
. sin(20)
= 735.0.913
= 671.0
cos 20° = 
=
. cos (20)
= 735.0.408
= 300
The force of static friction is 671N and normal force is 300N
