Answer:
The weight of the block of ice after 1 day is of 4.81 pounds.
Step-by-step explanation:
Equation for exponential decay:
The equation that models an amount after t hours, subject to exponential decay, is given by:
In which A(0) is the initial amount and r is the decay rate, as a decimal.
A 10-pound block of ice melts at a rate of 3% per hour.
This means that 
So
Find the weight of the block of ice after 1 day.
One day has 24 hours, so this is A(24).
The weight of the block of ice after 1 day is of 4.81 pounds.
Let x be the digit in the tens place and y be the digit in the ones place.
so, the digit is xy
<span>
The ten's digit of a two digit number is 1 more than 4 times the units' digit.
</span>x = 4y + 1
<span>63 is subtracted from the number, the order of the digits is reversed
</span>10x + y - 63 = 10y + x
9x - 9y = 63
x = 4y + 1 ------------ (1)
9x - 9y = 63 ---------- (2)
Sub (1) into (2)
9(4y + 1) - 9y = 63
36y + 9 - 9y = 63
27y = 63 - 9
27y = 54
y = 2 ------- sub into (1)
x = 4(2) + 1 = 9
x = 9, y = 2
The number is 92
What are the options? could you type it out a little more clear if possible? thanks!
The 2nd one I think brainlest me I was first
Answer:
The answer is 18x+64
={the five terms it gives you} <(they might be different for everyone)
Step-by-step explanation:
I had the same question on my quiz and I used process of elimination to get the answer. According to my quiz, I'm assuming that you've had the same four answer choices that I had.
First off, the variable must be on 18, since it says 18 flowers each, which will eliminate two answer choices, another piece of evidence is that X is supposed to represent the numbers of flower arrangements.
Now we are left with two different answer choices, one of which is missing a term. This is a problem since it says that he has enough to have up to five of them. Since one of the answer choices has only four terms, it is safe to say it is incorrect.
Conclusion
This leads the answer to be 18x+64={five terms, not four}
I hope this helps, good luck on the rest of your assignment/quiz! :D
