Answer:

BD = √97 cm ≈ 9.849 cm

Step-by-step explanation:

Diagonal BD of rectangle ABCD is the hypotenuse of right triangle ABD. Opposite sides of the rectangle are the same length, so we have ...

AB = 4 cm

AD = 9 cm

The sides are related to the diagonals by the Pythagorean theorem.

<h3>Pythagorean theorem</h3>

The Pythagorean theorem tells you the relation between sides and hypotenuse of a right triangle:

AB² +AD² = BD²

4² +9² = BD² = 16 +81 . . . . . evaluating the squares

BD = √97 . . . . . take the square root

The length of BD is √97 cm, about 9.849 cm.

Rico can walk 3 miles in the same amount of time that Donna can walk 2 miles. Rico walks at a rate 2 miles per hour faster than

tatyana61 [14]

Answer:

$13$

Step-by-step explanation:

Donna's Rate is $R$

Rico's Rate is $R+2$

$\frac{R}{R+2}=\frac{2}{3}$

Cross-Multiply

$2(R+2)=32$

$2R+4=3R$

$4=R$

Donna's Rate is $R=4$

Rico's Rate is $R+2=6$

$\frac{6(130)}{60} = \frac{130}{10}=13$

Diane has a rope that is 8 meters long. She cuts away a piece that is 1.67 meters long. How long is the remaining piece of rope?

Readme [11.4K]

Answer:

6.33 m

Step-by-step explanation:

Total length of the rope = 8 m

Cut length of the rope = 1.67 m

We need to find the remaining piece of the rope.

Remaining piece = Total length - cur length

= 8 m - 1.67 m

= 6.33 m

So, 6.33 m is the remaining piece of the rope.

A country has a population of about 124 million people and an area of about 1.95km^2.

BigorU [14]

Answer:

64 people/m^2

Step-by-step explanation:

The population density can be found by diving the number of people by the amount of area

I assume that the answer should be in metre squares or the area should be 1.95 million km^2

124000000/(1.95*1000000)

=63.5897...

=64 people/m^2
