The answer is A !!!!!!!!
the two segments AD and AB are equal therefore if you make the two equal to each other you will get the answer:
<span>x^2+2=11 then you subtract two to put x squared on the side by itself
</span>then you have <span>x^2=9
then all you have to do is take the square root of 9 and </span><span>x^2 and you get x=3
thefore the answer is A</span>
Step-by-step explanation:
a=7+3+7=17
b=3
h=8
area=(1/2)(17+3)(8)=80
The answer of 
is √ 2
<u>Step-by-step explanation:</u>
The value of 
= √2/ 2
The value of 
= √2/ 2
= √2/ 2 + √2/ 2
= √2 + √2 / 2
= 2 √2 / 2
Dividing √2 by 1
= √2
Answer:
very less
Step-by-step explanation:
When rolling a fair 6 sided die 5 times there are 6^5 possible combinations.
Of those, there are 5 ways to roll exactly four sixes, and each of those ways have 5 possible results on the die which has not rolled a six, plus there is 1 way to roll five sixes. 5*5+1=26 combinations with at least four sixes.
Now, take the number of results which fit your conditions, divide by the number of possible results and you get your answer: 26/7776 which can be reduced to 13/3338, a bit less than 0.4%
Im pretty sure she has 6 quarters and 12 nickels since it it twice as much.
$0.25 x 6 =150
$0.5 x 12 =60
total = 210
