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
Answer:
One angle is 46° and the other angle is 44°
Step-by-step explanation:
Complementary angle means the angles add up to 90 so:
90 - 44 = 46
Answer:
120/400 of the baseball gloves were left handed.
Step-by-step explanation:
Firstly, multiply 30% and 400 (just 30 x 400)
Secondly, with your solution (12,000), divide it by 100 (because of the percentage)
Lastly, you get your answer which is: 120 out of the 400 baseball gloves were left handed.
Answer:
10 or 10.1
Step-by-step explanation:
<h3>
#1</h3>
Given: f(x) = 3x² -5x + 4
To find f(-2), simply substitute x = -2 in function f(x).
f(-2) = 3(-2)² -5(-2) + 4
f(-2) = 12 + 10 + 4
f(-2) = 26
Answer: 26
<h3>#2</h3>
