In the given question, it is already mentioned that Pam takes 15 minutes to type 2.5 pages. this information should be used as the main information for reaching the desired answer.
Pam typed 2.5 pages in = 15 minutes
Then time taken by Pam to type 23 pages = (15/2.5) * 23
= 345/2.5
= 3450/25
= 138
So Pam will take 138 minutes to type 23 pages
Answer:
C
Step-by-step explanation:
(3^5)^2 = 3^10
(8^2)^5 = 8^10
therefore
(3/8)^10
Answer:
-1/2 is your answer.
Step-by-step explanation:
The slope formula is (y_2 - y_1)/(x_2 - x_1)
The y's are -3 and 2, while the x's are 9 and -1.
(-3-2)/(9-(-1))=-5/10=
-1/2 is your answer.
-- The 3 is the numerical coefficient of 'x'.
-- The 'x' is the literal coefficient of 3 .
The height of tree is 32 meter
<em><u>Solution:</u></em>
Given that, The sun is at an angle of elevation of 58 degree
A tree casts a shadow 20 meters long on the ground
The sun, tree and shadow forms a right angled triangle
The figure is attached below
ABC is a right angled triangle
AC is the height of tree
AB is the length of shadow
AB = 20 meters
Angle of elevation, angle B = 58 degree
By definition of tan,

In this right angled triangle ABC,
opposite = AC and adjacent = AB
Therefore,

Thus height of tree is 32 meter
