Find the missing length of the following trapezoid

Mathematics
1 answer:
Schach [20]3 years ago
4 0

Answer:

1) The length of DC is 20.

2) The length of PS is 17.

Step-by-step explanation:

1) If DR = RE and CS = SB, then we can use the following proportionality ratio:

\frac{DE}{DR} = \frac{32 - x}{26 - x} (1)

Where x is the length of segment \overline{CD}.

If DE = 2\cdot DR, then the value of x is:

2 = \frac{32-x}{26-x}

52 - 2\cdot x = 32 - x

20 = x

The length of DC is 20.

2) If QV = VP and RW = WS, then we can use the following proportionality ratio:

\frac{QP}{QV} =  \frac{x-7}{12-7} (2)

Where x is the length of segment \overline{PS}.

If QP = 2\cdot QV, then the value of x is:

2 = \frac{x-7}{5}

10 = x-7

x = 17

The length of PS is 17.

1 Katherine can run the perimeter of Kiker Park in
Vlad1618 [11]

The according to the perimeter, Parker takes 5 second longer than the Marin to run the perimeter.

According to the statement

We have to find that the comparison of the running time of the parker.

So, For this purpose, we know that the

Perimeter is the distance around the edge of a shape.

From the given information:

Katherine can run the perimeter of Kiker Park in 5.0 minutes and It takes Marin 1.45 minutes longer.

Marin takes 6.45 minutes and the Parker can run the perimeter of the park in 6.50 minutes.

Then from the statement it is clear that the

Time taken by Katherine = 5.0 minutes

Time taken by Parker = 6.50 minutes

Time taken by Marin = 5.0 minutes + 1.45 minutes

Time taken by Marin = 6.45 minutes.

from the timing we can say that the Marin's running time to Parker's running time is compared and the Parker takes 5 seconds more than the Marin.

So, The according to the perimeter, Parker takes 5 second longer than the Marin to run the perimeter.
