What must be the length of PQ in order for AJKL to be
similar PQR

Answer:

Step-by-step explanation:

1/20 hour = 5 minutes

(We can now call 1/20 of an hour 5 minutes)

If it falls 4/50 of a mile in 5 minutes (1/20 of an hour),

we do 4/50 * 12 because there are 12 5-minute intervals in an hour/

4/50 * 12 = 48/50 = 24/25 of a mile

Therefore, the raindrop will travel 24/25 of a mile in an hour.

The distance of the raindrop in an hour will be 24/25 miles.

The speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is a scalar quantity and is described by its magnitude only.

Given that A raindrop falls at a rate of 4/50 mile in 1/20 hour. The distance in an hour will be calculated as:-

If it falls 4/50 of a mile in 5 minutes ( 1/20 of an hour ),

Distance = 4/50 x 12

Distance = 4/50 x 12

Distance = 48/50

Distance = 24/25 of a mile

Therefore, the distance of the raindrop in an hour will be 24/25 miles.

Step-by-step explanation:

[tex](a-2b)^{3} \\=a^{3}-6a^{2} b+6ab^{2}-8b^{3}[/tex]

Given that,

[tex]a=(-3)\\b=(-1/2)[/tex]

So,

Answer:

D) 35 sq ft

Step-by-step explanation:

The options are:

A) 24 sq ft      B) 70 sq ft      C) 12 sq ft      D) 35 sq ft

So, when calculating the area of a regular rectangle or square, you need to multiply the base by the height (area=base*height)

So it is as simple as 7 multiplied by 5 which is 35 (7*5=35), so the answer is D) 35 square feet.

Answer:

  2πr cm

Step-by-step explanation:

The circumference of a circle of radius r is ...

  C = 2πr

For a radius of (r cm), the circumference is ...

  A = 2π(r cm) = 2πr cm

For a radius of (2r cm), the circumference is ...

  B = 2π(2r cm) = 4πr cm

Then the difference between the circumferences is ...

  B -A = (4πr cm) -(2πr cm) = 2πr cm . . . . difference in circumference

Answer:

x = 36 is not a solution

Step-by-step explanation:

3x<100

Let x = 36

3*36 < 100

108 < 100

This is not true so x = 36 is not a solution

Answer:

This inequality is False!

Step-by-step explanation:

3x < 100

3x36 < 100

108 < 100

Since 108 is greater than 100 this statement is not true. Hope this helps:)

Answer:

the slope: 2

Equation : y=2x-4

Answer:

-2

Step-by-step explanation:

use the rise over run equation: your rise is 8 and your run is -4

your first y is 4 and your second y is -4: 4 - (-4) is 8

your first x is -4 and you second x is 0; -4 - 0 is -4

dividing 8 by -4 will give you -2, which is your slope

Answer:

the equation is

Y-y = -33
