Answer:
C. .024
Step-by-step explanation:
You multiply 25 by 4 to get 100 and then you multiply 6 by 4 to get twenty four. After that you divide both numbers by one hundred and you get C
Answer: Perimeter = 22*sqrt(2)
Area = 60.5 inches
Step-by-step explanation:
Simple a square has 4 equal sides.
It contains (by definition) 1 right angle but since we are not including and statement about parallel sides, it needs 4 right angles.
Answer: 1/25 or 0.04
Step-by-step explanation:
1/5 divided by 5 for the whole number you have to turn it to a fraction so you would do 5/1
THEN: it becomes 1/5 divided by 5/1 but you have to do the inverse so the inverse of division is multiplying and you will cross multiply so 5*5= 25 and 1*1=1 therefor the final answer is 1/25
Answer:
no
Step-by-step explanation:
so in order for it to be a right triangle this would have to be true:
a^2 + b^2 = c^2
since c represents the hypoteneuse, it will be the longest side. so:
60^2 + 63^2 = 88^2
3600 + 3969 = 7744
7569 = 7744
since that statement is not true, the answer is no.
it is not a right triangle
the square root of 7569 is 87, so the triple would have to be : {60,63,87}
We know, cos A + cos B = 2cos(C+D)/2 × cos(C - D)/2
So,
cos 130 + cos 110 + cos 10
cos 130 + 2cos (110+10)/2 × cos( 110-10)/2
cos 130 + 2cos 60 × cos 50
cos ( 180 - 50 ) + 2cos60 cos 50
We know, cos ( 180 - A ) = -cos A
2cos 60 cos 50 - cos 50
Also, cos 60 = 0.5
2×0.5 cos 50 - cos50
cos 50 - cos 50
0 = RHS.
Hence proved
