Answer:
34° is the closest to the record high in degree Fahrenheit ⇒ C
Step-by-step explanation:
∵ The formula F = C + 32 is used to convert the temperature from
degrees Celsius (C) to degree Fahrenheit (F)
∵ The high temperature in Chicago is 1° Celsius
→ Substitute C in the formula above by 1
∴ F = (1) + 32
∴ F = + 32
∴ F = 33.8°
→ Round it to the nearest degree Fahrenheit
∴ F ≅ 34°
∴ 34° is the closest to the record high in degree Fahrenheit
She has 10lbs of 25% syrup... so, in the 10lbs, 25% of that is syrup, the rest, namely the 75% remaining is water or other substances.
let's say she adds "x" lbs of water, to get "y" lbs for the 10% mixture.
how much is 25% of 10lbs? well, (25/100) * 10, or 2.5.
the water has no sugar syrup in it, so is just pure water, so the amoun of syrup in it is 0%, how much is 0% of "x" lbs? well, (0/100) * x, or 0.00x, which is just 0.
how much is 10% of "y" lbs? well (10/100) * y, or 0.10y.
whatever "x" and "y" are, we know that 10 + x = y.
we also know that the syrup amount in that is also 2.5 + 0.00x = 0.10y, thus
