Answer:
e. 10√30
Step-by-step explanation:
In this right triangle geometry, all of the right triangles are similar. This means that the ratio of long side to hypotenuse is the same for all triangles:
x/(10+50) = 50/x
Multiplying by 60x, we have ...
x^2 = 3000
x = 10√30 . . . . . take the square root. Matches choice E.
_____
<em>Comment on estimating</em>
You're looking for x. Examining the figure, you see that x is the long side of the triangle with hypotenuse 10+50=60, so it will be shorter than that value. x is also the hypotenuse of the triangle with long side 50. So, x will be longer than 50.
The only answer choice with a value between 50 and 60 is choice E.
You don't even need to know how to find x. You only need to know that the hypotenuse is the longest side in a right triangle.
Answer:
The total cost of commodities = $61.82
Step-by-step explanation:
Sam visited the mall to purchase a shirt and a pair of shoes. The price of the shirt is $12.72. The price of the pair of shoes is $44.00.
The tax rate in the shop = 9%.
We have to find the total price Sam has to pay.
The total cost of the shirt and the pair of shoes = 12.72 + 44 = $56.72
Now there is tax of 9%.
So the cost becomes 1.09 times the initial value.
Hence the final price = 56.72
= $61.82
The final price of shirt and shoes = $61.82

Step-by-step explanation:</h2>
A linear equation is an equation of a line while a system of linear equations contains two or more linear equations that work together. A system of two linear equation has no any solution when the lines have the same slope. The graphed line shown in the Figure has an equation 
being the slope 
. Thus, from the options the line that has the same slope is 
. Finally, these two lines have no any because they are parallel.
Answer:
$56
Step-by-step explanation:
The computation of the amount that sandra would received as a refund is as follows:
= Amount paid in federal withholding tax - minimum tax paid
= $6,000 - $5,944
= $56
The amount left after deducting the minimum tax paid from the amount paid is the refund amount
hence, the last option is correct
The answer would be 0.0166666667.
