Answer:
7√3
Step-by-step explanation:
We can use pythagoreans theorem to solve this
Since, we know one side, and the hypotenuse, we can solve for the other side.
Pythagoreans theorem: a²+b²=c²
Where a and b are two sides, and c is the hypotenuse (the side opposite of the right angle)
In this triangle, 7 is the side, and 14 is the hypotenuse.
I will plug in the values into pythagoreans theorem, and then simplify:

So x = 7√3
Noah has 75 marbles. Noah has more marbles. this is because 34 times 3 is equal to 102. since michelle takes 9 marbles from EACH box, 9 times 3 is 27. 102 minus 27 is 75
Given conditions are :
In 1980's, a typical middle-income household earned= $34,757
In 2009, a similar middle-income household earned= $38,550
And we have to find relative increase in income for these households from 1980 to 2009.
So first we will find the total increase in amounts.

Relative increase = 
= 10.91% or rounding it off we get approx 11%.
Hence, the answer is 11%.
<u>Answer</u>:
The female would pay $322.00 less for a policy of $25,000
<u>Step-by-step explanation:</u>
Since we have given that
Amount for policy = $25000
If she opt for 20 year life insurance at $2.90 per $1000.
so, her amount of premium becomes

=$72.50
If she opt for straight life insurance at $15.78 per $1000,
Then, her amount of premium becomes

= $394.50
Difference between them is given by
$394.50-$72.5 = $322.00
The answer is C
Hope this helped:)
