Answer:
The -18°C temperature as the freezing point of maple syrup means that the temperature at which maple syrup changes from liquid to solid (that is, freezes) is 18° below the freezing point of water.
Step-by-step explanation:
It is explained that the freezing point of water is used as the standard or reference point to calibrate the Celsius scale.
The scientists use 0°C to represent the freezing point of water and subsequently use positive numbers to indicate temperatures above the freezing point of water and negative numbers to indicate temperatures lower than the freezing point of water.
So, a temperature/freezing point of -18°C simply means that the temperature/freezing point is 18° lower than the freezing point of water.
Hope this Helps!!!
Answer:
37.5
Step-by-step explanation:
3 ÷ 8 = 0.375
0.375 × 100 = 37.5
Answer:
4/5
Step-by-step explanation:
Of the hats in Deb's Hat Shop, 1/2 are purple and another 3/10 are red. What fraction of the hats are either purple or red?
The Fraction of the hats that are either purple or red are:
Purple + Red
= 1/2 + 3/10
Lowest Common Denominator is 10
= 5 + 3/10
= 8/10
= 4/5
Therefore, the fraction of the hats tha are either purple or red is 4/5
