It would simply take you 20 hours. 90/4= 22.5. 22.5/15= 2.5

Answer: 25 hrs 15 mins to go from Nazareth to Bethlehem with rest and 22 hrs 30 mins without rest

Step-by-step explanation:

So you go 8 miles at a time. 90/8=11.25 with 11 15 minute intervals in between. 165 minutes resting (well change it to hours later) and 8 miles takes 2 hours to walk. 2x11.25=22.5 hours. 165 minutes is 2 hrs and 45 mins. It would take 25 hrs and 15 mins to do the journey. If it’s asking how much longer compared to if you didn’t rest, that is 2 hrs and 45 minutes (the time spent resting is the difference between time with resting and time without resting)

Use the x-intercept method to find all real solutions of the equation. -9x^3-72x^2+36=3x^3+x^2-3x+8
larisa86 [58]

-9x^3-72x^2+36=3x^3+x^2-3x+8                     Add 9x^3 to both sides.

-72x^2 + 36 = 3x^3 + 9x^3 + x^2 - 3x + 8       Add 72x^2 to both sides

36 = 12x^3 +   73x^2 - 3x + 8                           Subtract 36 from both sides.

0 = 12x^3 + 73x^2 - 3x - 28      

It does factor, but it is not very nice.

(x + 6.06)(x - 6.09)(x + 0.632)

If there is any kind of error please report it in a note below.

Answer:

  a = 3, b = 12, c = 13

Step-by-step explanation:

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  (a^b)/(a^c) = a^(b-c)

  (a^b)^c = a^(bc)

___

You seem to have ...

  \dfrac{2^5\times8^4}{16}=\dfrac{2^5\times(2^3)^4}{2^4}\qquad (a=3)\\\\=\dfrac{2^5\times2^{3\cdot4}}{2^4}=\dfrac{2^5\times2^{12}}{2^4}\qquad (b=12)\\\\=2^{5+12-4}=2^{13}\qquad(c=13)

_____

<em>Additional comment</em>

I find it easy to remember the rules of exponents by remembering that <em>an exponent signifies repeated multiplication</em>. It tells you how many times the base is a factor in the product.

  2\cdot2\cdot2 = 2^3\qquad\text{2 is a factor 3 times}

Multiplication increases the number of times the base is a factor.

  (2\cdot2\cdot2)\times(2\cdot2)=(2\cdot2\cdot2\cdot2\cdot2)\\\\2^3\times2^2=2^{3+2}=2^5

Similarly, division cancels factors from numerator and denominator, so decreases the number of times the base is a factor.

  \dfrac{(2\cdot2\cdot2)}{(2\cdot2)}=2\\\\\dfrac{2^3}{2^2}=2^{3-2}=2^1

Select all the expressions that are equivalent to 18 + 4(m − 3) + 4m.
mixas84 [53]

Answer:

A 2(4m + 3)   Distribute 8m +6   match

C 8m + 6    This matches

Step-by-step explanation:

18 + 4(m − 3) + 4m

First distribute

18+ 4m -12 +4m

Then combine like terms

8m +6

Now see which expressions match

A 2(4m + 3)   Distribute 8m +6   match

D 4(2m + 4)  Distribute  8m + 16   no match

B 5m + 19  This does not have 8m   no match

E 8m + 16  This does not have 6 as a constant  no match

C 8m + 6    This matches
