Answer:

1725 ft²

Step-by-step explanation:

The formula for the area of a trapezoid is ...

A = 1/2(b1 +b2)h

Here, the bases are given as 65 ft and 50 ft, and the height is 30 ft. Then the area is ...

A = 1/2(65 ft +50 ft)(30 ft) = (1/2)(115 ft)(30 ft) = 1725 ft²

You tell the salesman your lawn area is 1725 square feet.

Total possible outcomes: (2)³=8 (heads or tails possibility on each toss)

Draw out a Tree diagram to illustrate the given example, labelling the probability on each branch.

Adding all the possible situations with P(t)≥2, we get 0.352 as the probability.

Hope I helped :)

ABC ~ ADE AC = 4, AE = 7, AD = 10, what is the length of AB? 1 3/7 2 1/2 5 5/7 17 1/2

Butoxors [25]

If the polygon or the figures are similar then it is known that the ratios of their corresponding sides and angles are proportional. In this item we can derive an equation that is,

AC/AE = AD/AB

Substituting the known values,

4/7 = 10/AB

AB from the equation is equal to 70/4 or equal to 17 ½.
