Vladimir79 [104]

Answer:

x = 3.75

Step-by-step explanation:

ABC is a right angled triangle.

Therefore, by Pythagoras theorem:

${(10 - x)}^{2} = {x}^{2} + {5}^{2} \\ 100 - 20x + {x}^{2} = {x}^{2} + 25 \\ 100 - 20x = 25 \\ - 20x = 25 - 100 \\ - 20x = - 75 \\ x = \frac{ - 75}{ - 20} \\ \: \: \huge \red { \boxed{x = 3.75}}$

Ann [662]

2.857 m away from the wall. because if it is 1.3 m off the ground when fired then you just subtract that from 2.9 to get 1.6 then divide that by sin (38.2) to get 2.857 m from the wall.

If the student has already read 2525 of the pages, how long will it take them to read the rest of the book? _____ minutes Your a

Alja [10]

The number of pages the student can read in a minute is an illustration of rates.

The time left to complete the whole book is 90 minutes

From the complete question, the student's rate is:

$\mathbf{Rate = 50\ pages/hr}$

The number of pages is:

$\mathbf{Total = 100\ pages}$

First, we calculate the time to read the whole book

$\mathbf{Total\ Time = \frac{Total\ pages}{Rate}}$

$\mathbf{Total\ Time = \frac{100\ pages}{50\ pages/ hr}}$

$\mathbf{Total\ Time = 2\ hours}$

The number of the student has read is:

$\mathbf{Pages = 25}$

Next, we calculate the time spent on the 25 pages

$\mathbf{Time\ Spent = \frac{Pages}{Rate}}$

$\mathbf{Time\ Spent = \frac{25\ pages}{50\ pages/hr}}$

$\mathbf{Time\ Spent = 0.5\ hr}$

Convert to minutes

$\mathbf{Time\ Spent = 30\ minutes}$

So, the time left is:

$\mathbf{Time\ Left = Total\ Time - Time\ Spent}$

This gives

$\mathbf{Time\ Left = 2\ hours- 30\ minutes}$

$\mathbf{Time\ Left = 1\ hour, 30\ minutes}$

Convert to minutes

$\mathbf{Time\ Left = 90\ minutes}$

Hence, the time left is 90 minutes
