Tanner watched 1/4 of a movie in the morning, and he watched some at night. By the end of the day, he still had 2/3 of the movie
bazaltina [42]

Answer: he watched 1/12 of the movie at night.

Step-by-step explanation:

Let x represent how much of the movie that he watched at night.

Tanner watched 1/4 of a movie in the morning, and he watched some at night. This means that she had already watched

x + 1/4 = (4x + 1)/4 of the movie by the end of the day. Therefore, what he has left to watch would be

1 - (4x + 1)/4 = [4 - (4x + 1)]/4

= (3 - 4x)/4

By the end of the day, he still had 2/3 of the movie to watch, it means that

(3 - 4x)/4 = 2/3

Cross multiplying, it becomes

3(3 - 4x) = 4 × 2

9 - 12x = 8

12x = 1

x = 1/12

What is the value of f(15) for the given function? What does this value mean in the context of the situation you described in pa
bija089 [108]

Answer:

f(15)=525\ ft^{2}

f(15) is the area of the rectangular garden for a width of 15 ft

Step-by-step explanation:

we know that

f(x)=x(2x+5)

where

x----> is the width of the rectangular garden

(2x+5) ----> is the length of the rectangular garden

so

f(15) -----> is the value of f(x) for x=15 ft

That means

f(15) is the area of the rectangular garden for a width of 15 ft

substitute the value of x and solve

f(15)=15(2(15)+5)

f(15)=525\ ft^{2}
