Answer:
f6h40
Step-by-step explanation:
Step 1 :
h23
Simplify ———
f3
Equation at the end of step 1 :
h23
((f9) • ———) • h17
f3
Step 2 :
Multiplying exponential expressions :
2.1 h23 multiplied by h17 = h(23 + 17) = h40
Final result :
f6h40
First keep in mind that the center is 5 inches...let L and R be the left and right positions of the two flames...
L=h and R=10-1.5h where h is in hours....
The two flames meet when L=R so we can say:
h=10-1.5h add 1.5h to both sides
2.5h=10 divide both sides by 2.5
h=4
So the flames will meet in five hours, using either original equation we can find this position, I'll use L=h..
L=4
So the position of the flames is 4" from the end. The questions ask how far this point is from the center so:
5-4=1"
So the flames meet 1 inch from the center.
Answer:

Step-by-step explanation:
Answer:
-125/27
Step-by-step explanation:
(-3/5)^-3= 1÷(-3/5)³
=1÷(-3³/5³)
=1÷(-27/125)
=1×(125/-27)
=-125/27
