If you draw a diagonal from upper left to lower right, you divide the figure into two triangles. One is a 3-4-5 right triangle (with area = (1/2)*3*4 = 6). The other is a 5-5-4 isosceles triangle.
The altitude of the isosceles triangle (upper left vertex to side 4) can be found from the Pythagorean theorem as
.. altitude = √(5^2 -2^2) = √21
So, the area of the isosceles triangle is
.. (1/2)*4*√21 = 2√21
The sum of the areas of the two triangles matches selection C.
The correct answer is B.If a and b are odd,then axb is odd.
Answer:
2 1/6 hours.
Step-by-step explanation:
It walks 1 1/2 miles in 3 1/4 hours.
So it walks 1 mile in (3 1/4 ) / (1 1/2) hours.
= 13/4 / 3/2
= 13/4 * 2/3
= 26/12 hours
= 2 1/6 hours.
Answer:
Step-by-step explanation:
First of all it should be like fractions
So -2/3 becomes -10/15
and -3/5 becomes -9/15
-9/15 is greater than -10/15
-3/5 is greater than -2/3
