Answer:
12 sapphires
Step-by-step explanation:
Let's call the number of sapphires x. This means the number of rubies is the total number of gems minus x, or 17-x.
# of Sapphires: x
# of Rubies:17-x
A sapphire is worth 5 (gold coins) each, and a ruby is worth 8.
We also know the total amount of money is 100 coins, so
5*x+8*(17-x)=100
5x+136-8x=100
-3x=-36
x=12
Remember:
# of Sapphires: x
# of Rubies:17-x
...so Lara found 12 sapphires and 17-12=5 rubies.
Answer: The volume of the sphere is 8177.08
Step-by-step explanation:
v= 4/3nr^3
v= 4/3*3.14*1953.125
v= 8177.08
17% of 800= 136
83% of 800= 664
166.5
area a is multiplied by y. Aka length times width
This polynomial can't be factored further. the three terms have nothing in common that make it factorable--you can't take anything out of all three terms.
however, if you perhaps mistyped and meant u² + 2uv + v², you would be able to factor it into (u + v)(u + v).
