Tickets to an outdoor concert were $30 for front-seating and $20 for lawn seats. there were 600 more lawn seat tickets sold than front seats. sales for all the tickets totaled $30,000. samantha is making a chart to determine the total sales (in dollars) for lawn seats. she defines x as the number of front-seat tickets. which expression could samantha use on the chart to represent the total dollar sales for lawn tickets? a) 20(x + 600) b) 20(x − 600) c) 20x d) 30(x − 10)

it is probably the graph on the bottom right.

answer: answer: d) v= 1/6 bh  

step-by-step explanation:

since according to the given question,   a pyramid is placed inside a prism.

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
