An engineer is designing a new dam for a river. the retaining wall of the dam will be angled such that the height above the ground of the top at the wall is three times the horizontal distance between where it begins and where it ends at ground level. the outer angled wall will be 100-feet long. this relationship is shown below.

which system of equations can be used to determine y, the height above the ground at the top of the wall, and x, the horizontal distance between where the wall begins and where it ends at ground level.

recall the pythagorean theorem, a2 + b2 = c2, where a and b are the side lengths of a right triangle, and c is the length of the hypotenuse.

Urgentwhat is the area of the figure?

Customers are used to evaluate preliminary product designs. in the past, 93% of highly successful products received good reviews, 51% of moderately successful products received good reviews, and 14% of poor products received good reviews. in addition, 40% of products have been highly successful, 35% have been moderately successful and 25% have been poor products. round your answers to four decimal places (e. g. 98.) what is the probability that a product attains a good review? (b) if a new design attains a good review, what is the probability that it will be a highly successful product? (c) if a product does not attain a good review, what is the probability that it will be a highly successful product?
