Answer:

Step-by-step explanation:

The answer is B. Shape A is a square which all the sides are the same length. This mean it has 2 pairs of parallel sides. Shape B is a rectangle which also has 2 pairs of parallel sides. Shape C is rhombus which also has 2 pairs of parallel sides. Shape D is a trapezoid which only has 1 pair of parallel sides.

Answer:

Step-by-step explanation:

the second one is correct. the first one is wrong because shape C also has those angles. the third one is wrong because shape C also has no perpendicular sides. the fourth one is wrong because shape C also has 2 pairs of angles with the same measure.

A. The perimeter of a rectangle is twice the length plus twice the width. If L represents the length and W represents the width

vampirchik [111]

Perimeter P = 2L + 2W

b. P = 2*1010 + 2*1818 = 2020 + 3636 = 5656 inches

c. Area A = WL

d Area = 1010*1818 = 1836180 in^2

A long distance runner does a first lap around a track in exactly 50 seconds.As she tires.Each subsequent lap takes 20% longer t

madreJ [45]

Answer:

182 seconds

Step-by-step explanation:

Given:

Time taken for first lap is 50 seconds and each subsequent lap takes 20% longer than previous

Solution:

Time taken for first lap = 50 sec

For second lap

Each subsequent lap takes 20% longer than previous

Previous lap time = 50 sec

second lap = 50 + 20% of 50

second lap $=50+(\frac{20}{100}\times 50)$

second lap $= 50 + 10$

second lap $= 60\ sec$

For third lap

Each subsequent lap takes 20% longer than previous

Previous lap time = 60 sec

Third lap = 60 + 20% of 60

$Third\ lap = 60 + (\frac{20}{100}\times 60)$

$Third\ lap = 60+2\times 6$

$Third\ lap = 60+12$

$Third\ lap = 72\ sec$

Time taken for 3 laps is equal to sum of all three laps time.

$Tiem\ taken\ for\ 3\ lap = 50+60+72$

$Tiem\ taken\ for\ 3\ lap = 182\ sec$

Therefore, it takes 182 seconds (3 min, 2 seconds) to run three laps

Using the formula find the slope of a line with the points (10,20) and (30,50).

VARVARA [1.3K]

Answer:

m = 2/3

Step-by-step explanation:

Slope is defined as the ratio rise/run.

As we move from (10, 20) to (30, 50), the run is 30 - 10, or 20, and the rise is 50 - 20, or 30. Thus, the slope of the line is m = 30/20, or 2/3.
