Answer:
Step-by-step explanation:
I do not understand your question very well but I think that the state of the glass of the water would be liquid and solid at the same time since the water would not freeze 100% and would be with small pieces of solid and some parts liquid, in terms of temperature, I think that at 5 minutes it would be 5 ° C and at 10 it would be 3-4 ° C the longer it is in the freezer the less its temperature will be
(All of that is my point of view)
Average temperature 30 °
So :
30 ÷ 15 = 2 °
30 ÷ 10 = 3 °
30 ÷ 5 = 6 °
Answer:
a = 6 or a = -58/8
Step-by-step explanation:
I think you meant to ask us to solve for a.
There are two cases to solve for:
5 + 8a = 53 or -(5 + 8a) = 53
8a = 48 or 5 + 8a = -53
a = 6 or 8a = -58
a = 6 or a = -58/8
Answer: Driving Speed
Step-by-step explanation:
The Independent variable is the one that is being experimented on to see the effect it will have on the dependent variable.
The Independent variable is adjusted to different levels to see if a relationship exists between these adjustments and a change in the dependent variable.
In this scenario the independent variable would be the speed you drive your car whilst time taken to completely stop is the dependent variable because the speed is the variable being adjusted to see the time taken to completely stop the car.
The present age of George is 25 years and the present age of Harry is 17 years
For given question,
Let x be the age of George and y be the age of Harry.
George is now 8 years older than harry.
So, we get an equation,
x = y + 8 ...................(1)
After 5 years the age of George will be x + 5 and the age of Harry will be y + 5
Two years ago the age of Harry = y - 2
In 5 years George will be twice as Harry was 2 years ago.
So we get an equation,
x + 5 = 2(y - 2) ..............(2)
Substitute the value of x in equation (2)
⇒ x + 5 = 2(y - 2)
⇒ y + 8 + 5 = 2y - 4
⇒ y + 13 = 2y - 4
⇒ y = 17
Substitute the above value of y in equation (1)
⇒ x = 17 + 8
⇒ x = 25
Therefore, the present age of George is 25 years and the present age of Harry is 17 years
