Answer:
YZ = 44
Step-by-step explanation:
Let the intersection of XW and YZ equal A. For this problem, we can use power of a point in the scenario where two secants intersect in the interior of a circle. We get the equation:
WA * AX = ZA * AY
We can substitute the values we are given to get:
(2x - 6)(21) = (x + 1)(30)
42x - 126 = 30x + 30
12x - 126 = 30
12x = 156
x = 13
Using segment addition postulate, we can say that:
YZ = YA + AZ
And we can plug in what we know from the diagram:
YZ = 30 + x + 1
We can also plug in the value of x, 13
YZ = 30 + 13 + 1 = 44
Answer: 10

Answer:
41/62 = .66
Hope this helps :)
Step-by-step explanation:
41/4 / 31/2
keep change flip
41/4 * 2/31
82/124
Simplify
82/124 = 41/62
41/62 = .66
Answer:
Meghan's weekly allowance is $60
Step-by-step explanation:
The first thing you need to do is know how much the camera is and how much Seth has already. If Seth already has $299.99 and the camera costs $699.99, you need to work out how much more you need.
699.99-299.99=400
$400
You need $299.99 more so you divide that by 5
59.998
Money is in 2 decimal point so you round to two.
Which gives you 60
That way, Meghan has $60 a week
Answer:
Step-by-step explanation:
To rationalize the above fraction multiple both numerator and denominator by the conjugate of its denominator.
We can simplify √8 like this :
√8 = √4 × √2
√8 =<u> 2√2</u>
<u>Let us rationalize the above fraction now.</u>
<em>Solve the brackets and roots.</em>
<em>Simplify the roots.</em>
√75 = √25 × √3
√75 =<u> 5√3</u>
