suppose we are given an isosceles triangles with a leg measuring 5 in two lines are drawn through some point on the base, each parallel to one of the legs. Find the perimeter of the constructed quadrilateral. WILL GIVE 25 POINT TO WHOEVER GET IT RIGHT FIRST

Browning labs is testing a new growth inhibitor for a certain type of bacteria. the bacteria naturally grows exponentially each hour at a rate of 6.2%. the researchers know that the inhibitor will make the growth rate of the bacteria less than or equal to its natural growth rate. the sample currently contains 100 bacteria.the container holding the sample can hold only 300 bacteria, after which the sample will no longer grow. however, the researchers are increasing the size of the container at a constant rate allowing the container to hold 100 more bacteria each hour. they would like to determine the possible number of bacteria in the container over time.create a system of inequalities to model the situation above, and use it to determine how many of the solutions are viable.

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

Out of $20$ creepy-crawly creatures in a room, $80\%$ are flies and $20\%$ are spiders. if $s\%$ of the total legs belong to spiders, what is $s$?
