Sam sold 1/4 of his raffle tickets. He has 60 left to sell. How many tickets he has sold? Draw a picture or diagram that explains your thinking.

Sam has sold 20 tickets,

The attached diagram also represents this scenario.

Step-by-step explanation:

1/4 means Sam has sold 1 portion of raffle tickets out of 4 portions.

So, he has 3 portions left. As 60 are the  number of raffle tickets left to cell.

Therefore, divide 60 by 3 equal portions/parts. i.e. 60/3 = 20

As all parts/portions are equal, it means each portion contains 20 tickets.

Therefore, Sam has sold 20 tickets,

The attached diagram also represents this scenario.

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
