A computer can perform 4.5×〖10〗^2 instructions in a second. Which expression shows how long it would take to perform 1.8×〖10〗^10 instructions?
8.1×〖10〗^12 seconds
Answer:
A
Step-by-step explanation:
b must always be greater than 0 since 12b-15 must always be greater than 21. You can simplify the ineqaulity to see things easier; 12b>36. Again, this ineqaulity can be simplified; b>3. A is the closest answer here, but there should be an open interval at 3 for A to be correct.
Answer:
Option 4, BC = 12.689, m∠A = 58°, and m∠C = 32°
Hope this helps!
