Answer:
The temperature outside is 75.6°F
Step-by-step explanation:
We are given the following in the question:
The temperature of dry ice = - 109.3°F
Let x be the temperature outside in Fahrenheit.
It is given that the temperature of dry ice is 184.9°F less than the outside temperature.
Thus, we can write the equation:

Solving, the above equation, we get:

Thus, the temperature outside is 75.6°F
The answer to this question would be <span>B. Mystic

Since the rate should be constant, option C and D wouldn't be true.</span>
If the Four Rivers bank gives 12% per year and Mystic Bank gives 14% per year, it will be 3% per quarter year for Four Rivers Bank and 7% semiannually for Mystic Bank.
The total rate would become:
Four rivers 103%^4= 1.125
Mystic : 107%^2= 1.145
780, or C, is correct. Since 9.75 is 1/80th of the actual measurement, we can set up an equation like this:
9.75 = 1/80x
Then multiply each side by 80:
780 = x
The actual building's height is 780 ft.
We can check this answer by plugging in 780 for x in the original equation:
9.75 = 1/80(780)
9.75 = 9.75

We can round 5.65 up to 6 and 3.4 down to 3.
3 * 6 = 18
now let's see how close our estimate is to the real answer
5.65 * 3.4 = 19.21
Our answer was pretty close to the real answer!
Hope I helped!
