Step-by-step explanation:
$2.00x-($.10x)=3+x
the x would stand for cups and since you already get 3 more cups in a day than before then you would put 3+x_how many cups you sell. the $2.00 is for how much money each up is. and the -$.10 is subtracting 10 cents for each cup you sell.
I dont know if this is correct but this is how I would make my equation
Answer:
Let x = the number
A negative number is 42 less than its square ⇒
x = x2 - 42
x2 - x - 42 = 0
(x - 7)(x + 6) = 0
x = 7 or -6
But since it is given that x is negative, the final answer is x = -6.
Answer:
<u>The radius of the cylinder and sphere is 2.48 cm and the volume of the sphere is 64 cm³</u>
Step-by-step explanation:
Let's review the information given to us to answer the question correctly:
Volume of a cylinder = π * r² * h
π * r² * h = 48
r² * h = 48/3.1416
r² * h = 15.28
r = 2.48 cm, h = 2.48 cm
Now, we can calculate the volume of the sphere this way:
Volume of the sphere = 4/3 * π * r³
Volume of the sphere = 4/3 * π * 2.48³
Volume of the sphere = 4/3 * π * 15.28
Volume of the sphere = 1.33 * 3.1416 * 15.28
<u>Volume of the sphere = 64 cm³</u>
Answer:
4 + (2 + 1)2 = 4 + (3)2 = 4 + 9 = 13
