She will have £262 left to pay at the end of five months.

Step-by-step explanation:

Exponential equation for an amount:

A exponential equation for an amount that decays has the following format:

$A(t) = A(0)(1-r)^{t}$

In which A(0) is the initial amount, r is the decay rate, as a decimal, and t is the time measure.

Sue owes an amount of £800

This means that A(0) = 800

Each month, she pays back 20% of the amount she still owes.

This means that r = 0.2

$A(t) = A(0)(1-r)^{t}$

$A(t) = 800(1-0.2)^{t}$

$A(t) = 800(0.8)^{t}$

How much will she still have left to pay at the end of five months?

This is A(5). So

$A(5) = 800(0.8)^{5} = 262$

She will have £262 left to pay at the end of five months.

Answer from: Quest

"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).

step-by-step explanation:

75% of the temperatures are below what value? how do you know? 75% of the temperatures are above w
