Answer:
D. x ≤ -18
Step-by-step explanation:
-x/6 ≥ 3
Multiply both sides by 6.
-x ≥ 3 × 6
-x ≥ 18
Multiply both sides by -1 and reverse the inequality.
x ≤ 18 × -1
x ≤ -18
Answer:
198
Step-by-step explanation:
No. of Pencils in a box = 45
No. of Boxes of Pencil = 22
Total No. of Pencils = 
= 990
No. of fourth grade classes = 5
So, the no. of pencils each class will receive is,

= 198.
Each class will receive 198 pencils.
Answer:
The equation is 
Step-by-step explanation:
From the question we are told that
The diameter endpoints is (-8, -3, -10) and (-6, 1, -4)
Generally the equation of a sphere with center coordinates (a, b , c ) and radius r is mathematically represented as

Now since we are given the endpoints of the diameter then we can obtain the center coordinates as follows
![(a, b , c) = [ \frac{ -8 +(-6)}{2} , \frac{-3 + (1)}{ 2} , \frac{ -10 + (-4)}{2} ]](https://tex.z-dn.net/?f=%28a%2C%20b%20%2C%20c%29%20%3D%20%20%5B%20%5Cfrac%7B%20-8%20%2B%28-6%29%7D%7B2%7D%20%20%2C%20%20%5Cfrac%7B-3%20%2B%20%281%29%7D%7B%202%7D%20%20%2C%20%5Cfrac%7B%20-10%20%2B%20%28-4%29%7D%7B2%7D%20%5D)
![(a, b , c) = [ -7 , -1.5 , -7 ]](https://tex.z-dn.net/?f=%28a%2C%20b%20%2C%20c%29%20%3D%20%20%5B%20-7%20%2C%20%20-1.5%20%20%2C%20-7%20%5D)
Now the length of the diameter is evaluated as




Now the radius is mathematically represented as



So




There are 35 quarters and 15 dimes.
