Answer: 44g
Step-by-step explanation:
Half life refers to the length of time it takes for half of the atoms of the element in question to decay.
The half life here is 1 minute which means that in a minute, the amount of protactinium left would be:
= 352 / 2
= 176g
After the second minute:
= 176 / 2
= 88g
After the third minute:
= 88 / 2
= 44g
Answer:
hope this helps :)
Step-by-step explanation:
Since we know how far she can walk in 1/5 (one fifth) of an hour, if we multiply this distance by 5, we will find out how far she can walking in 5/5 (five fifths) of an hour, or to be clear: in one hour.
So, 5 x 1/4 miles = 5/4 or 1.25 miles per hour
Jazmeen can walk 1.25 miles in one hour.
Answer: The distance from the base of one pole to the top of the other pole is approximately 108.17 feet
Step-by-step explanation:
The scenario is shown in the attached photo. Two congruent right angle triangles, ABC and BAD are formed. Since the triangles are the same, we would consider only one of them.
Let the distance from the base of one pole to the top of the other pole be x feet.
Considering triangle ABC,
Hypotenuse = x feet
Opposite side = 60 feet
Adjacent side = 90 feet
Applying Pythagoras theorem,
Hypotenuse^2 = Opposite^2 + Adjacent ^2
This becomes
x^2 = 60^2 + 90^2
x^2 = 3600 + 8100 = 11700
x = √11700 = 108.16653826392
Approximately 108.17 feet
Answer:
D) 74
Step-by-step explanation:
1c = 6p
1c = 1.5f
1f = 296
6/1.5 = 4
296/4 = 74
