Answer:
Option B
Step-by-step explanation:
First make x = 4 and y = 3 in the equation y = -1/2x + 5
it should look like 3 = -1/2(4) + 5 now we can solve
-1/2 * 4 = -2 → 3 = -2 +5
-2 + 5 = 3 → 3 = 3
Answer:
3,451 cm³
Step-by-step explanation:
The ball is a sphere.
Formula for finding the volume of a sphere = ⁴/3*πr³
Volume of the 3 balls = 3(⁴/3*πr³)
Where,
radius (r) = ½ of diameter = ½(13) = 6.5 cm
Plug in the values into the formula:
Volume of the 3 balls = 3(⁴/3*π*6.5³)
= 4*π*274.625
= 3,451.03953 ≈ 3,451 cm³
Answer:
(D) Each year,the machinery loses a value of 4,500
When it is 3 years old,it is worth a little over 35K ,and when it is 6 years old,its worth about 22K.
This info means A,C and B is wrong b/c it loses too little value per year.
