6. 2 h 14 min= 134 min
134min/26.2 mi = 5.114 min/mi

7. 9834.9-8546.3=1348.6 mi
1348.6 mi/65.4 gal=20.6 mi/gal

8. 5 miles = .4x
x=5/.4
x=12.5 laps

9. 8 x 3600=28800 sec
28800/8001=3.6 sec/kiss

If p is inversely proportional to the square of q, and p is 22 when q is 8, determine p when q is equal to 2. 9 w

Amiraneli [1.4K]

Answer:

167.42

Step-by-step explanation:

p = 1/q²

22 = k* 1/8² .........k is the constant which we re finding now

k = 1408

p = 1408/2.9²

= 167.42

Tree C is the proper tree. The first game has the possibility of a win, a loss, or a tie which the first row represents. The second game could also win, lose or tie, meaning each result would have each possibilty for that game.

For any nonnegative real number.

frutty [35]

Answer:

Step-by-step explanation:

We know that $\sqrt{b}=b^{1/2}$ .

We also know that $(a^b)^c=a^{bc}$ .

We can combine these facts to get $(\sqrt{b})^2=(b^{1/2})^2=b^{1/2*2}=b^{1}=b$ .

So, the answer is $\boxed{A}$ and we're done!

<em>Note: the non-negative part or the equation comes from the fact that you assume the square root of a negative number doesn't exist. You will change this assumption later in the year, or in further years.</em>

Cora says he dosen't need to know the y-interce of a line to write its equation,just its slope and some other point on the line.

Soloha48 [4]

Answer:

Yes, Cora is correct.

The equation of line with point (2,6) and slope of line (-1/3)

is x + 3y - 20 = 0

Step-by-step explanation:

Yes, the equation of a line can be written using a point and a slope of the line equation.

Cora has used the POINT SLOPE FORMULA, to represent the line equation.

In <u>Point Slope formula</u>:

The equation with slope m and points (x0,y0) can be written as:

(y-y0) =m (x-x0)

Here, the point (x0,y0) = (2,6)

and slope m = (-1/3)

So, the equation can be written as: $( y - 6) =\frac{-1}{3} (x-2) \\\implies 3( y-6) = (2-x)\\or, 3y - 18 -2 + x = 0\\or, x + 3y - 20 = 0$

Hence, the equation of line with point (2,6) and slope of line (-1/3)

is x + 3y - 20 = 0
