Answer:

x = 9.8 (rounded)

Step-by-step explanation:

the diagonal within the quadrilateral measures

\sqrt{(12)^{2} +(12)^{2} } =\sqrt{288} =16.97

Calculate x on the right triangle of which it is a leg

tan60^{0} =\frac{16.97}{x}

x=\frac{16.97}{tan60^{0} } =9.797

Hope this helps

How would you find the number, 3/7 of which is equal to t? (let's say it was any number, just need the equation)
ohaa [14]
Let the number be x
(3/7) x = t
I can't think of anything useful to add to this. How about an example?

Let x = 49

(3/7) x = t
(3/7) * 49 = t seven will go into 49
3 * 49 = t
t = 147

Which is not an equation of the line going through (6, 7) and (2, –1)?
garri49 [273]
Answer - D.

you basically find the equation of the line first and eliminate the wrong answers...

Strategy:  before u do any of this, label your coordinates as (X1,Y1) and (X2,Y2) and u can choose any of ur points to be as x1 or x2 or y1 or y1...
basically, I'll choose (6,7) as (x1,y1) and (2,-1) as (x2,y2). SO,

First you have to  find the gradient (m) of the line.
  you do this by using the formula m = Y2-Y1 / X2-X1 (where '/' is division sign) ....
Put the numbers in their respective places and your gradient will be 2x. we put the x after our number to represent it as a gradient as the straight line formula is y = mx+c and you've found the m.
NOW.
use the formula Y-Y1=m(x-x1) to find the equation of the line.Again u can use any Y1 and X1 here but remember your m is 2

replace the digits and solve...Hopefully you'll get sth like this if you use the points (6,7):
Y-7 = 2(x-6) ....
y=2x-12+7...
Y=2x-5! <<<< this is your straight line equation!
Now all u gotta do is rearrange all your options into y = mx+c.
D. is incorrect as it gives us y=2x+5 and not y = 2x-5 unlike the others 
 

Hope you get it!

A public beach in Florida charges non residents $8 per day for a fishing license and $2.50 per day for live bait. Florida reside
melamori03 [73]

For a non-resident:

C_{nr}=8d+2.5d=10.5d

For a resident:

C_{r}=114+1d

We want to know the number of days d such that the two costs are equal ie \{d|C_{nr}(d)=C_{r}(d)\}

To do this set the two costs equal to each other:

C_{nr}=C_{r}

10.5d=114+1d

And solve for d:

10.5d-1d=114+1d-1d

9.5d=114

d=\frac{114}{9.5}

d=12

The costs will be equal when a resident and a non-resident each use the beach for 12 days.
