Answer:
B
Step-by-step explanation:
To get x by itself, you have to divide each side by the number that x is attached with.
For the first one, divide each side by 3 so that x is by itself and 21/3 is 7 to get x<7
Do the same with the other side but with 5 to get x>11
Answer:
See explanations below
Step-by-step explanation:
Volume of the sphere is expressed as;
V = 4/3πr³
r is the radius
V = 4/3 * 3.14 * 3³
V = 4/3 * 3.14 * 27
V = 4 * 3.14 * 9
V = 113.04cube units
For the secind sphere;
diameter = 12
radius = 12/2 = 6
V = 4/3πr³
r is the radius
V = 4/3 * 3.14 * 6³
V = 4/3 * 3.14 * 216
V = 4 * 3.14 * 72
V = 904.32cube units
Task 1 -----

Task 2 ----- 3 min 10 sec = 3+10/60 =

Task 3 ----- 1 min
Total time to make 1 item =

+1 =

minutes
In 25 minutes;
Number of items made = 25/(6 2/3) = 3.75 items = 3 items (since only a fully assembly can be regarded as an item).<span />
1,600 vases must be produced and sold to break even.
x($28-$11)=$27,200
Simplify to 17x=27,200
Divide 17x by 17 so it cancels out.
What you do to one side of the equation you have to do to the other.
27,200/17=1,600
x=1,600
To find slope you can use rise over run over run
