It would be: = 56 1/4 % = 225/4% = 225/4/100 = 225/400 = 9/16
In short, Your Answer would be 9/16
Hope this helps!
Answer:
∠1 = 72°
Step-by-step explanation:
Complementary angles sum to 90°, thus
∠1 + ∠2 = 90, substitute ∠1 = 4∠2 , thus
4∠2 + ∠2 = 90
5∠2 = 90 ( divide both sides by 5 )
∠2 = 18°
Hence ∠1 = 90 - 18 = 72°
The area of every circle is (pi) (radius²) .
Radius = 1/2 of the diameter, so the area of your circle is
(pi) x (8 cm)² = 201 cm² . (rounded)
(pi) is not 3 . There's nothing wrong with approximating (pi),
but 3 is more than 4.5% wrong, and that's too much. There's
no reason why 3.14 should be too hard to handle.
Answer:
Yes.
Step-by-step explanation:
The two triangles are <em>similar</em> because they have:
- a common angle (90°)
- corresponding sides with lengths in a 3:1 ratio
All you need to do is to slide the smaller triangle into the larger one so that a small angle and one of its sides coincide.
Then the hypotenuses of each triangle will lie along the same line.
Answer:
C. -11,325
Step-by-step explanation:
- To know the answer, is convenient to replace some values of "n" in the sum
.
- The result would appear after adding up every value of the expression
when n=1,2,3.....,150. - When n=1, the expression takes the value of (-1):
. - When n=2, the expression takes the value of (-2):
. - Following this way, for every n, we will obtain -n, then, the sum will be:
. This sum can actually be expressed as
, which is the result of solving the initial expression of the sum
. - Finally, the sum of n=-1 to n=-150 equals -11,325.
