0.333   IS rounded to the nearest thousandth....

Thank you so much Alan

Notice that the numerator of each term cancels with the denominator of the next term, so that overall you are left with \(\frac{a}{2}=9\)

Hence a = 18.  The denominator of each term is just 1 less than the numerator, so b = a-1 = 17.

It said rounded to the nearest thousandth

60 miles per hour. 

The cost of a book is $4. 

 Express your answer as the ordered pair (a,b).

Hello Guest!

\(f(x)=\frac{1}{1.5}x+1\\ g(x)=x^2\\ f(x)=g(x)\)

\(\frac{2}{3}\cdot x+1=x^2\\ x^2-\frac{2}{3} x-1=0\\ x=\frac{1}{3}\pm \sqrt{\frac{1}{9}+1}\)

\(x\in \{-0.721,1.387\}\)

\(\{a,b\}=\{-0.721,1.387\}\)

The price of a book went up from $20 to $25. ...

Thank you for this.

$12 + $4 = $16

5 - 3 = 2

$16 / 2 = $8

0.333  

The altitude divides the hypotenuse into two segments, each of length 4.

The area is  ½ · 8 · 4  =  16

0.330

The x-intercepts are -8 and 1   --->   a distance of 9 (the base)

The y-intercept is 8 (the height)

Area  is  ½ · 9 · 8  =  36

The first term is 6.

The common ratio if -8/6.

The 205th term is:  6(-8/6)²⁰⁴.

Draw a line through P that is parallel to BC.

If P is "below" that line, the area of triangle(PBC) will be less than one-half the area of triangle(ABC).

The area below that line is three times the area above the line, so the probability that the area of

triangle(PBC) is less than the area of triangle(ACB) is 3/4.

The probability that the first occurs, the second doesn't and the third doesn't:  (1/3)(5/7)(4/5)

or

the probability that the first doesn't occur, the second does and the third doesn't:  (2/3)(2/7)(4/5)

or 

the probability that the first doesn't occur, the second doesn't and the third does:  (2/3)(5/7)(1/5)

Find each of the above individual probabilities and add their answers together.

But this question in NOT 10 minutes earlier but 15 minutes earlier. So, the first answer of 72 mph is correct.

Check your math.....the Q asked for 15 minutes earlier.....

Chris got 60 mph: https://web2.0calc.com/questions/3-questions-on-algebra

"

It takes Tina  30miles / 45mph  =  2/3 of an hour to get to work  = 40 minutes

So......10 minutes earlier is 30 minutes.....so........to travel 30 miles in 30 minutes....she must travel at 1 mile per minute  =  60 mph   "

it should be 63/64

Yeah

I think its 171
