Answer:
The measure of the angles are 55° and 35°
Step-by-step explanation:
Sum of two angles that are complement of each other are 90.
The angles are A and B, so we can write:
A + B = 90
Also,
The difference is 20. Let A be the greater of them, so we can write equation 2 as:
A - B = 20
Now, we add up both equations, eliminate B and solve for A first:
A + B = 90
A - B = 20
---------------
2A = 90 + 20
2A = 110
A = 110/2
A = 55
And now the measure of B:
A + B = 90
55 + B = 90
B = 90 - 55
B = 35
Answer:
1 / 1728
Step-by-step explanation:
( 1 / 64 ) / 27
= 1 / ( 64 x 27 )
= 1 / 1728

Answer:
There are twelve 12 bottles in one full box.
Step-by-step explanation:
From the given information:
suppose there are 9 water bottles in the refrigerator,
and 3 full boxes of water are being added, we do not know the total number of bottles in a box, so let's represent it by b
i.e. 3b
However, two more boxes are being added which had 1 fewer bottle than the full box.
i.e. 2(b-1)
Now to determine the number of bottles in a full box, we have:
9 + 3b +2(b-1) = 67
9 + 3b + 2b - 2 = 67
5b + 7 = 67
5b = 67 - 7
5b = 60
b = 60/5
b = 12
Hence, there are twelve 12 bottles in one full box.
