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
Answer:
I THINK THIS IS IT
Step-by-step explanation:
They washed a total of 96 cars during both car washes. How many cars did they wash during the spring car wash? ANSWER: 2x – 14 = 96; 41 cars.
For every hour she works, her earnings go up by $10.
Jacinda: d = 10 * t ( a rate: 10 miles per hour )
Raj : d = 1.5 + 4.5 * t
Jacinda will catch up with Raj when:
10 t = 1.5 + 4.5 t
10 t - 4.5 t = 1.5
5.5 t = 1.5
t = 1.5 : 5.5 = 0.27 hours = 16.2 min = 16 min 12 seconds
