Out of 100 people who attended a concert (pre-Corona obviously), 26 bought a teeshirt and 42 sat in the lawn section. Six students who sat in the lawn section also bought tee shirts. If a person who attended the concert was randomly selected, what is the probability that they bought a teeshirt if it is known that they did not sit in the lawn section? The first term in a geometric series is 5 and the common ratio is 2. Find the sum of the first 10 terms in the series.

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.

step-by-step explanation:

for volume, add base x height x width
