Answer:The surface area of the cube is 100 cm.
Step-by-step explanation:
So since a cube has six faces and all of its lengths are equal. we could use the equation.
10^2 *6= 100 *6= 600
1.2 meters = 120 centimeters
amount of increase = 120-80 = 40 centimeters
40 ÷ 80 = 0.5 = 50%
There was a 50% increase.
The measure of <ABD, <DBC and <ABC are 67, 67 and 134 degrees respectively.
<h3>Bisection of angles</h3>
Angles are bisected if they are divided into two equal parts.
If the angle BC bisects <ABC, hence <ABD and <DBC are equal, hence;
2(11x + 23) = <ABC
Given the following parameters
<ABC = 25x + 34
2(11x + 23) = 25x + 34
Expand
22x +46 = 25x + 34
22x-25x = 34 - 46
-3x = -12
x = 4
Determine the measure of the angles
<ABD = 11x + 23 = <DBC
<ABD = 11(4) + 23
<ABD = 44 + 23
<ABD = 67 degrees
<ABC = 2(67)
<ABC = 134 degrees
Hence the measure of <ABD, <DBC and <ABC are 67, 67 and 134 degrees respectively.

Answer:
38 quarters
Step-by-step explanation:
0.25 x 63 = 15.75
0.05 x 63 = 3.15
----------------------------
0.25 x 50 = 12.50
+ = $13.15
0.05 x 13 = 0.65
----------------------------
0.25 x 25 = 6.25
+ = $8.15
0.05 x 38 = 1.90
----------------------------
0.25 x 30 = 7.50
+ = $9.15
0.05 x 33 = 1.65
--------------------------
0.25 x 35 = 8.75
+ = $10.15
0.05 x 28 = 1.40
-------------------------
0.25 x 38 = 9.50
+ = $10.75
0.05 x 25 = 1.25
------------------------------
I hope this helps!
