Answer:

The polygons are similar.

Step-by-step explanation:

By definition, the corresponding sides and angles of similar polygons must be in some constant proportion.

Therefore, we can find the ratio between corresponding sides to see if that ratio is maintained.

The side marked 3 cm in the smaller figure corresponds with the side marked 3.75 cm in the larger figure. This proportion is $\frac{3}{3.75}$ .

The side marked 5 in the smaller figure corresponds with the side marked 6.25 cm in the larger figure. This proportion is $\frac{5}{6.25}$ .

If these polygons are similar, these proportions must be equal.

$\frac{3}{3.75}=\frac{5}{6.25},\\0.8=0.8\:\checkmark$

Checking, we see that these proportions are equal, and therefore the polygons are similar.

A levee protects a town in a low-lying area from flooding. According to geologists, the banks of the levee are eroding (wearing

Cloud [144]

Answer:

The signed number that indicates how much of the levee will erode during the next decade is:

-30 feet

Step-by-step explanation:

a) Data and Calculations:

Erosion rate of the banks of the levee = 3 feet per year

For 10 years, if nothing is done to correct the problem, the eroded banks will be equal to 10 * 3 = 30 feet

Therefore, the signed erosion in the next decade is -30 feet.

b) The quantity of erosion can be given as the number of years involved without correction, multiplied by the rate of erosion per year. This implies that the quantity of erosion depends on the number of years and the rate of erosion per year.

What happens to the value of the expression 2t/t as t decreases

anyanavicka [17]

Answer:

it stays the same until t=0, where it is undefined

Step-by-step explanation:

2t/t = 2 . . . . when t ≠ 0

2t/t = undefined when t = 0.

The value of t can increase or decrease and the value of the ratio remains the same. The value has a "hole" at t=0, where it is undefined. Otherwise, its value is always 2.
