Answer:
169
Step-by-step explanation:
13*13=169
We can split the two 13's up:
(10+3)(10+3)
Multiply 10 with 10, 10 with 3, 3 with 10, and 3 with 3.
Basically, just multiply every single term together.
100+30+30+9
100+69
169
Hope this helps!
Answer:
Step-by-step explanation:
If the bathroom scale make an angle of 20°
Then, we need to resolve it to the vertical axis
W=mg
Then weight on the vertical axis is
W=W•Cos20
Since cos20 is less than 1
The weight is lower than it's actual weight because the weight that will be recorded on the scale is the normal weight and which is
N=W•Cos20
N=0.94W
%reduction = (actual weight-measure weight)/actual weight ×100
%reduction= (W-0.94W)/W × 100
%reduction=0.06W/W× 100
℅reduction =6%
It will be reduce by 6% of his original weight
Answer:
Step-by-step explanation:
Sample space = {1, 2 , 3 , 4 , 5, 6, 7, 8, 9, 10}
In Euclidean geometry, the angles of a triangle add to 180, which means the remaining angle has a measure of 86 degrees.
In spherical geometry, it's impossible to know the measure of the remaining angle precisely without knowing any more info about the triangle. The sum of the interior angles is between 180 and 540 degrees, so the missing angle is somewhere between 87 and 445 degrees.
