First, convert 2/5 to a decimal by dividing 2 by 5:
2/5 = 0.4
Now, multiply:
0.4 x 8.75 = <u><em>3.5 gallons</em></u><em></em>
Hope this helps!

Suppose that $a$ is a positive integer for which the least common multiple of $a+1$ and $a-5$ is $10508$. What is $a^2 - 4a + 1$
Nana76 [90]

Answer:

21022.

Step-by-step explanation:

Find the prime factors of 10508:

2 ) 10508

2 ) 5254

37 ) 2627

       71.

50208 = 2*2*37*71.

Now there is no integer value for a that would fit  (a+ 1)(a - 5) = 10508 .

But we could try multiplying the LCM by 2:-

= 21016  = 2*2*2*37*71.

= 2*2*37 multiplied by 2 * 71

= 148 * 142.

That looks promising!!

a - 5 = 142 and

a + 1 = 148

This gives  2a - 4 = 290

2a = 294

a = 147.

So substituting a = 147 into a^2 - 4a + 1 we get:

= 21022.

ratelena [41]

Answer:

I believe your answer is C 94.79

If this answer is wrong please let me know my apologies

Step-by-step explanation:

If my math is correct

44.50+44.50=89

89

Now, find the tax value by multiplying tax rate by the before tax price:

tax = 85 × 0.065

tax = 5.53 (tax value rounded to 2 decimals)

Add tax to the before tax price to get the final price:

The final price including tax = 85 + 5.53 = 90.53

90.53 plus the shipping 3.89=94.79
