Answer:

Hey there!

60 hrs in 5 weeks is equal to 3600 minutes in 35 days.

So, each day you would have to do 102.86 minutes.

Hope this helps!

Answer:

102 minutes

Step-by-step explanation:

If you have to work 60 hours in five weeks, there are seven days in a week so I multiply 7 by 5 (5 being the number of weeks) and I divide that by 60, getting 1.7 hours a day, which is 102 minutes. Hope this helped!

The cells of a bacteria doubles in every 15 minutes. A scientist begins with a single cell. How many cells will be there after (

Anastaziya [24]

Step-by-step explanation:

Given that:-

1 cell = 15 minutes

So, we can concert 15 minutes to hours.

So,

60 minutes = 1 hour

1 minute = 1/60

15 minutes =

$\frac{15}{60} = 0.25 \: hrs$

Okay, now we will apply first for 0.4 hours.

$0.25 \: hrs= 1 \: cell$

$1 \: hr = \frac{1}{0.25}$

$0.4 \: hrs = \frac{0.4}{0.25}$

$= 1.6 \: cells$

$= 16 \times {10}^{ - 1} \: cells$

Now, second one:-

$10 \: hrs = \frac{10}{0.25}$

$= 40 \: cells$

$= 0.4 \times {10}^{2} \: cells$

Hope it helps :D

Are all congruent rectangles similar?

shusha [124]

All congruent rectangles similar because comparable shapes are not always congruent.

Given that,

We have to find are all congruent rectangles similar.

We know that,

Each side's length and the angles that separate them match those of the other shape's corresponding sides and angles. Comparable shapes are not always congruent, whereas congruent shapes are always similar.

So,

Similar figures are not always congruent, whereas congruent figures are always similar. For similar figures, we simply take into account the shapes, however for congruent triangles, we take into account both the shapes and sizes of the figure.

Therefore, All congruent rectangles similar because comparable shapes are not always congruent.

What is your reading rate if you read 2/3 of a chapter in 3/4 an hour expressed in chapters per hour

andrew-mc [135]

¾ an hour is 45 minutes

So to have your answers you need to do a cross product :

45 minutes —> 2/3 of a chapter
60 minutes —> X of a chapter

((2/3) • 60) / 45

40/45 = 8/9

Answer : You read 8/9 of a chaper per hour! :)

Find dy/dx any one <br>x=acost , y=asint

dangina [55]

Answer:

$x=a \cos t \implies \dfrac{dx}{dt}=-a \sin t$

$y= a \sin t \implies \dfrac{dy}{dt}=a \cos t$

Using the chain rule:

$\begin{aligned}\implies \dfrac{dy}{dx} & =\dfrac{dy}{dt} \times \dfrac{dt}{dx}\\\\& = a \cos t \times \dfrac{1}{-a \sin t}\\\\& = \dfrac{a \cos t}{-a \sin t}\\\\& = - \dfrac{\cos t}{\sin t}\\\\& = - \cot t\end{aligned}$
