That depends on it's maximum height
but assuming the max is 160 feet then the answer is 1 second to attain max height since its 160 ft per second
Answer:
The original number is 28
Step-by-step explanation:
start by listing all possible combinations of digits that give 10 when added:
19 (1+9=10)
28 (2+8 =10)
37 (3+7=10)
46 (4+6=10)
55 (5+5=10)
Look into the order of digits reversed and what the difference with the original number gives:
1) 19 reversed is 91 then when we subtract 91 - 19 we obtain 72
2) 28 reversed is 82 hen when we subtract 82 - 28 we obtain 54 which is the combination we where trying to find.
Notice as well, that as we go down the list, the differences between reversed digit number and original become smaller (and ends being zero for the number 55), so they do not satisfy the requirement.
Therefore 28 is the answer, since 82 (the new number formed when the digits are reversed) exceeds the original number by 54.
Answer:
x = 76°
Step-by-step explanation:
Corresponding angles are formed when a transversal line cuts across two parallel lines. The angles formed are in corresponding position close to the transversal. Corresponding angles formed like this are congruent.
In the diagram given above, BD and XY are parallel lines cut across by a transversal line.
Angle labelled x corresponds with the angle measuring 76°. Therefore they are both congruent. Thus: x = 76°.
