Value of a is 3.22

Step-by-step explanation:

Solving the given expression:

2\frac{1}{7}:(1.5a)=\frac{5}{14}:0.8

Solving and finding the value of a.

2\frac{1}{7}:(1.5a)=\frac{5}{14}:0.8\\\frac{15}{7}:(1.5a)= \frac{5}{14}:0.8\\Ratio\,\,can\,\, be\,\, written\,\, in\,\, fraction\,\, form:\\\frac{\frac{15}{7}}{1.5a}=\frac{\frac{5}{14}}{0.8}\\ Cross\,\,multiply:\\\frac{15}{7}*0.8=\frac{5}{14}*1.5a\\1.71=0.53\,\,a\\a= \frac{1.71}{0.53}\\a=3.22

So, value of a is 3.22

In a doctor's waiting room, there are 14 seats in a row. Eight people are waiting to be seated. There is someone with a very bad
diamong [38]

Answer: 12,972,960

Step-by-step explanation: There are 14 chairs and  8 people to be seated. But among the 8. three will be seated together:

So 5 people and (3) could be considered as 6 entities:

Since the order matters, we have to use permutation:

¹⁴P₆ = (14!)/(14-6)! = 2,162,160, But the family composed of 3 people can permute among them in 3! ways or 6 ways. So the total number of permutation will be ¹⁴P₆  x 3! 

2,162,160 x 6 = 12,972,960 ways.

Another way to solve this problem is as follow:

5 + (3) people are considered (for the time being) as 6 entities:

The 1st has a choice among 14 ways

The 2nd has a choice among 13 ways

The 3rd has a choice among 12 ways

The 4th has a choice among 11 ways

The 5th has a choice among 10 ways

The 6th has a choice among 9ways

So far there are 14x13x12x11x10x9 = 2,162,160 ways

But the 3 (that formed one group) could seat among themselves in 3!

or 6 ways:

Total number of permutation = 2,162,160 x 6 = 12,972,960

Solve for y<br> a. 4x + 5y = 25
AfilCa [17]

Answer:

y = -4/5x + 5

Step-by-step explanation:

In order to solve for y, we need to isolate the variable. First, let's subtract 4x on each side. After doing said step, we should now have this equation:

5y = -4x + 25

Next, we need to divide 5 on each side, giving us this new equation:

y = -4/5x + 5

There you go! Let me know if I did anything wrong ^-^
