You have 36 pages to read for homework. In 5 minutes you read 10 page if you countinue to read at the same rate how many times w
kykrilka [37]

Answer:

18 minutes

Step-by-step explanation:

5 mins = 10 pages

10 mins = 20 pages

15 mins = 30 pages

20 mins = 40 pages

Just keep adding 5 to the minutes and 10 to the pages. then if you divide 10 by 5 (10÷5) you get 2.

2 is the amount of pages you read in 1 minute.

so 1 minute = 2 pages

Since you only need to read 36 pages, you know that it would at least take you 15 mintes to read 30.

then you start adding 1 minute until you get to 36 pages.

15 minutes = 30 pages

16 minutes = 32 pages

17 minutes = 34 pages

18 minutes = 36 pages

Therefore, it should take 18 minutes to read all 36 pages.

(A shorter way of doing this would be doing 10÷5=2, then just dividing 36 by 2 (36÷2) and you would get 18 which would be the minutes it would take you to read all 36 pages if you read at 2 pages per minute.)

SVETLANKA909090 [29]
For this case, we can model the problem as a rectangle triangle.
 We know:
 Height of the triangle.
 Base of the triangle.
 We want to know, angle between the hypotenuse and the base of the triangle.
 For this, we use the following trigonometric relationship:
 tan \alpha =  \frac{7.4}{9.3}
 Clearing the angle we have:
 \alpha = arctan(\frac{7.4}{9.3} )
 \alpha = 39
 Answer:
 
the angle of depression from the spotlight to the bottom of the door is:
 
A) 39 degrees
