Answer:
It will take 9 hours with 4 painters to paint 720 feet of fence.
Step-by-step explanation:
Given that,
The time needed to paint a fence varies directly with the length of the fence
.......(1)
and inversely with the number of painters
.....(2)
Combination of (1) and (2) is

where t represents time,
represents length of fence, P represents number of painters.
Again we can write the above equation as


Given that,
It takes 7 hours with 2 painters to paint 280 feet of fence .
We need to find time to paint 720 feet of fence with 4 painters.
=7 hours,
=280 feet,
=2,
=? ,
= 720 feet,
=4




It will take 9 hours to paint 720 feet of fence with 4 painters.
First, you would distribute 2 into the parentheses so you would have 6x-8= 5x+6. Subtract 5x from both sides so you have x-8=6. Finally, add 8 to both sides which leaves you with x= 14
Answer:
1.) Exponential Growth
2.) Exponential Decay
3.) Exponential Growth
4.) Exponential Decay
Step-by-step explanation:
<u>1.) </u><u><em>f (x) </em></u><u>= 0.5 (7/3)^</u><u><em>x</em></u>
↓
always increasing
<u>2.) </u><u><em>f (x) </em></u><u>= 0.9 (0.5)^</u><u><em>x</em></u>
<em> </em>↓
always decreasing
<u>3.) </u><u><em>f (x) </em></u><u>= 21 (1/6)^</u><u><em>x</em></u>
↓
always increasing
<u>4.) </u><u><em>f (x) </em></u><u>= 320 (1/6)^</u><u><em>x</em></u>
<em> </em> ↓
always decreasing
<u><em>EXPLANATION:</em></u>
It's exponential growth when the base of our exponential is bigger than 1, which means those numbers get bigger. It's exponential decay when the base of our exponential is in between 1 and 0 and those numbers get smaller.
Answer:
i believe the answer is 332
Step-by-step explanation:
basically what i did was divide 3 and 996. when you do that it will let you know the estimate number of the number times she got number 3 on the die.
