The answer is -19 because I asked my math teacher and she said-19
Answer:
x = 33
y = 41
Step-by-step explanation:
GIven
x: number of nickels
y: number of quarters
A nickel = $0.05
A quarter = $0.25
then we have the system of equations
0.05*x + 0.25*y = 11.90
x + y = 74
Which can be solved applying any of known methods. Then, the solution is
x = 33
y = 41
hope this was helpful.
Answer:
Step-by-step explanation:
6/2=3 cm is the radius V(4/3πr³) = 4/3.π.27…(1)
8/2= 4 cm is the radius and V = 4/3.π.64…..(2)
10/2=5 cm is the radius and V = 4/3.π.125…(3)
The Total Volume is the addition of (1)+(2)+(3) or 4/3π (27+64+125) or New volume is 4/3.π.(216) cm³ and therefore...
The radius of the New Solid Sphere is Cube Root of 216 (r³) = √6.6.6 or r = 6 cm and the diameter is 6.2 = 12 cms.
12 cms answer. Brainlist please?
