Answer:

(a)4

Step-by-step explanation:

First you would distribute the 2 within the parentheses and it becomes 14n-46 <= 14-16n. Then you would find the smallest coeficent and do the inverse operation so you would have to add 16n to 14n and get 30n. Your equation is now 30n-46<=14. Now you want to isolate the variable by doing the inverse operation of -46. You would then add 46 to positive 14 and get 60. Your eqaution now is 30n<=60. Your last step is to divide 30 on each side which leaves you with n<=2.

2 is less than or equal to 2

-2 is less than or equal to 2

-4 is less than or equal to 2

4 is NOT less than or equal to 2 it is GREATER

Hopefully, that helps.

Answer:

∠MDP = 90° = Right angle

∠MDP = 180° = Straight angle

∠ODM = 90° = Right angle

∠OND = Not an angle

∠NDO = 90° = Right angle

∠NDM = 180° = Straight angle

∠PMN = Not an angle

∠PDO = 180° = Straight angle

∠PDN = 90° = Right angle

Zepler [3.9K]

Answer:

B) 14

Step-by-step explanation:

We can plug in the values of m and p into the equation:

1/2 m + 3p = 1/2 (16) + 3 (2) = 8 + 6 = 14.

Water flows at a rate of 8000 cubic inches per minute into a cylindrical tank. The tank has a diameter of 128 inches and a heigh

beks73 [17]

Answer:

The height of the water = 6.2 in. to the nearest tenth

Step-by-step explanation:

∵ The rate of flows of water into the tank = 8000 in.³/min.

∴ The volume of the water in the tank after 10 min. = 8000 × 10 = 80000 in.³

∵ The water take the shape of the tank

∴ The height of the water = volume of water ÷ Area of the base of the tank

∵ The tank is cylinder with diameter 128 in. and height 72 in.

∴ The area of the base of the tank = π(128/2)²

∴ The height of the water = $\frac{80000}{\pi(64)^{2}}=6.2169899$

∴ The height of the water = 6.2 in. to the nearest tenth
