Brainliest if right! a gallery owner is hanging up 444 pictures for an art exhibit. she has put up 37 pictures in 9 minutes. if she continues at the same rate how many more minutes will it take her to hang the rest of the pictures? 111 minutes 99 minutes 0.75 minutes 46 minutes

Divide the number of pictures put up so far (37) over the time in minutes taken (9) to get
37/9 = 4.11
This value is the approximate unit rate. So she can put up roughly 4.11 pictures per minute

The question is: how long will it take her to put up 444 pictures?

Let x = amount of time it takes to put up all the pictures

It turns out that
(unit rate)*(time) = number of pictures put up

So
4.11*x = 444

Divide both sides by 4.11 to isolate x
4.11*x = 444
4.11*x/4.11 = 444/4.11
x = 108.03
which rounds to 108 minutes

This is the total time it takes to put up all the pictures. Since the question asks about the additional time needed after the initial 9 minutes, we need to subtract off 9
108 - 9 = 99

Final 99

It takes an additional 99 minutes to put up the remaining pictures

"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).

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.
