Answer:
32-gon
Step-by-step explanation:
5402 = (n - 2) · 180
5402/180 = n-2
30 = n-2
32 = n
14.50 × 7%
= 1.015
= 14.50 + 1.015
= 15.515

Answer: 9/10 of a mile per hour.
Step-by-step explanation:
For each ounce of the product, let
x = ounces of moisturizing lotion used,
y = ounces of self-tanning lotion used.
The sum of the two lotions per ounce is equal to one ounce. Therefore
x + y = 1 (1)
Moisturizing lotion costs $0.70 per ounce.
Self-tanning lotion costs $22 per ounce.
Because the product costs $1.30 per ounce. Therefore
0.70x + 22y = 1.30 (2)
From (1), obtain
y = 1 - x (3)
Substitute (3) into (2).
0.70x + 22(1 - x) = 1.30
0.70x - 22x + 22 = 1.30
-21.3x = -20.7
x = 0.9718 ounces
From (3), obtain
y = 1 - 0.9718 = 0.0282 ounces.
A batch of the product is 700 ounces. Therefore the amount of self-tanning lotion used is
700*y = 700*0.0282 = 19.74 ounces
Answer: 19.74 ounces
Answer:
1,440 bottles will be packed in an hour
Step-by-step explanation:
Firstly, we need to calculate the Amount of Distance the conveyor belt will move in an hour.
Now the speed with which it moves is 2 feet per seconds. We calculate the number of seconds in a hour= 60 * 60 = 3600 seconds. The total distance is thus 3,600 * 2 = 7,200 ft
Now, to calculate the number of bottles to be packed in an hour, we simply divide the total distance covered by the distance between the bottles = 7,200/5 = 1,440 bottles
