A honeybee flaps its wings 200 times per second.how much time is required for one wingbeat? give your answere in millisecond
Fiesta28 [93]

The time required for one wing beat is 5 milliseconds.

<em><u>Explanation</u></em>

Lets assume, the time required for one wing beat is  t seconds

So, the time required for 200 wing beat = 200t seconds

Given that, the honeybee flaps its wings 200 times per 1 second. So...

200t=1 \\ \\ t=\frac{1}{200}seconds\\ \\ t= (\frac{1}{200}*1000 )milliseconds\\ \\ t=( 5 )milliseconds

So, the time required for one wing beat is 5 milliseconds.

Which is the most likely first step needed to solve this equation?
Vanyuwa [196]

Answer:

C.  Add 15 to both sides

Step-by-step explanation:

Given equation:

99x – 15 = 45

To solve:

<u>Step 1</u>:  Add 15 to both sides:

⇒ 99x – 15 + 15 = 45 + 15

⇒ 99x = 60

<u>Step 2</u>:  Divide both sides by 99:

⇒ 99x ÷ 99 = 60 ÷ 99

⇒ x = 60/99

⇒ x = 20/33

(05.01)A scale drawing of a living room is shown below. The scale is 1 : 40.
matrenka [14]

Answer:

A=266\frac{2}{3}\ ft^2

Step-by-step explanation:

we know that

The scale is \frac{1}{40}

That means

1 unit in the drawing represent 40 units in the actual

or

1 inch in the drawing represent 40 inches in the actual

step 1

Find the actual dimensions of the living room

Multiply the dimensions of the living room in the drawing by 40

Length:\ 6(40)=240\ in

Width:\ 4(40)=160\ in

step 2

Convert inches to feet

Remember that

1\ ft=12\ in

To convert inches to feet , divide by 12

so

Length:\ 240\ in=240/12=20\ ft

Width:\ 160\ in=160/12=\frac{40}{3}\ ft

step 3

Find the area in square feet

Multiply the length by the width

A=(20)(\frac{40}{3})=\frac{800}{3}\ ft^2

Convert to mixed number

A=\frac{800}{3}\ ft^2=\frac{798}{3}+\frac{2}{3}=266\frac{2}{3}\ ft^2
