She is wrong. The way we know this is by this. If you are going 70 mph for 30 miles than you have to spilt the mph sign in half so 35 miles in 30 minutes.The you subtract 4 from each getting 31 miles in 26 minuets. Therefore Lethna is wrong.

Large reusable bottles cost $4 more than small ones. Eight large bottles cost $24 less than 12 small ones. How much does one sma

ss7ja [257]

A small bottle costs $14.

To solve the problem, the equation would be this:

$8(4+s)=12s-24$

Let s represent a small bottle. Since one large bottle is $4 more than a small one, you would write out (4+s). Then, multiply it by 8 to find one side of the equation, and get 8(4+s). To write out the right side of the equation, you would write out 12s to represent 12 small bottles, and subtract 24 from that to represent that 8 large bottles is $24 less than 12 small ones.

Then, proceed to solve the equation to get the answer of s=14. Because a small bottle is $14, you can check your work by substituting the 14 in replace of s.

Answer:

0.61

Step-by-step explanation:

The computation of the probability of the working of the system is shown below:

But before that first we have to find out the total probability of sub-system i.e 2,3 and 4 i.e

$= 0.75\times0.8\times0.8$
