<span>B. Decreases.
While evaporation is happening, the temperature is slowing cooling down due to not as much water in the pot that is holding the water. If you have ever taken boiling hot water and dumped half of it out, and immediately put it back on the stove, it doesn't start boiling right away. It takes minutes to heat it back up to that boiling temperature.</span>
Answer:
FALSE
TRUE
TRUE
Step-by-step explanation:
Here, let us first state the logarithmic rules.
Now, here the given expressions are:
The given statement is FALSE as:
The given statement is TRUE .
The given statement is TRUE as:
<span>Out
of 50 customers surveyed, 22 of them stated that they would buy a protection
plan.
On the next day, 700 customers came.
Let’s predict how many of them would probably buy the protection plan.
Ratio = 50 : 22 = 700 : x
=> 700 * 22 = 15 400
=> 15 400 / 50 = 308
Thus, if 700 customer came in the next day, around 308 of the customers will
buy life plan.</span>
Answer:
x = 1; y = 5
Step-by-step explanation:
-2x + 3y = 13
;
y = 7x - 2
Since the second equation is already solved for y, substitute y of the first equation with 7x - 2.
-2x + 3y = 13
-2x + 3(7x - 2) = 13
-2x + 21x - 6 = 13
19x - 6 = 13
19x = 19
x = 1
Now substitute x of the second equation with 1 and solve for y.
y = 7x - 2
y = 7(1) - 2
y = 7 - 2
y = 5
Solution: x = 1; y = 5
