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.
Assuming that ' i ' is the old familiar square root of -1 ...
The square of 6i is -36 .
Of course, if ' i ' is something else, then (6i)² = 36 i² .
Answer:
60.96 cm
Step-by-step explanation:
To find the amount Chester needs using his centimeter ruler, convert 2 feet into inches and then into centimeters.
Each foot has 12 inches so 2*12 = 24 inches. 2 feet is 24 inches.
To find the number of centimeters, 24 inches * 2.54 cm = 60.96 centimeters
Area of circle = pi x r^2
= 22/7 x 40^2
= 5028.57
= 5030cm^2 (3 SF)
