A group of 5 girls went to the library to study for an upcoming biology test. Each girl studied for the amount of time. If the total amount of time they spent studying was 8 hours, how long did each girl study for?
x represents how long each girl studied for
5x = 8 divide 5 on both sides and you get 1.6, so the amount each girl spent studying is 1 hour and 36 minutes
LN is 180 degrees
180 - 41 = x
x = 139 degrees
hope this helps
Answer: Rahul walks 2.7 km more than Vansh.
Step-by-step explanation:
The options include:
a. Vansh walks 7.2 km more than Rahul.
b. Vansh walks 2 km more than Rahul.
c. Rahul and Vansh both cover the same distance.
d. Rahul walks 2.7 km more than Vansh.
Distance covered by Rahul weekly = 9km
Distance covered by Vansh weekly = 900m × 7 = 6300m = 6300/1000 = 6.3km
From the above, we can see that Rahul walk (9km - 6.3km) = 2.7km more than Vansh.
Note: 1000 meters = 1 kilometers
3x/10-2 = x/5+2
+2 +2
3x/10 = x/5+4
x10 x10
3x = x(5 x 4)
-x -x
2x = 20
/2 /2
x=10
Ok so 1.5 is pins and 6.5 is t shirts so you multiply 1.5 x 20 and 6.5 x 5 so for pins= $30 and T-shirts= $32.50 and you times both those numbers by 3 so for pins you get $90 and T-shirts you get $97.50. Finally you add them and get $187.5 so the answer is $187.5 for the project.
