Answer:
<em> 3 years old </em>
Step-by-step explanation:
( 21 + 24 + 18 + 15 + 15 + x ) / 6 = 16
93 + x = 96
x = 3
<em>The person who entered the room is 3 years old.</em>
Isocoleese means that 2 sides and hence 2 angles are same measure
acute means that all 3 angles are less than 90 degrees
We can rule out choice I since acut means less than 90
II is a possibility, but it doesn't best describe it
III. that is true, but it doesn't include the isocileese part
IV. that is true, but doesn't include the acute part
not sure, either III or IV
Answer:
The total surface area is 336ft2
Step-by-step explanation:
solution:
total suface area of the pyramid
=area of base square +(12)2 = 4 (1/2 x 12 x 8)
=144+192
=336ft2
then the total surface area is 336ft2
The distance between -2 1/2 - (-3)
-2 1/2 + 3
1/2

450/3 = x.
150 = x.
So x = 150.
This means 45 is 30% of 150
