Step-by-step explanation:
make a negative and positive sign coordinate plane
plot it on -2
First we need to understand that the sum of adjacent angles on a straight line is 180°,meaning that when all the angles are added up the answer would be 180°
Here's how we can set up the equation:
2x+100°=180°
2x=80°
x=40°
Thus the answer is 40°

Answer:
width of one box = 1.25 inches
Step-by-step explanation:
Given data:
12 congruent boxes
Length = 25 inches
height = 2 feet
Volume = 9000 cubic inches
First change the height into inches
1 foot = 12 inches
therefore 2 feet = 24 inches
Volume = Length * width * height
9000 = 25 * width * 24
9000 = 600 * width
width = 9000/600
width = 15 inches
width of one box = width of all boxes / number of boxes
width of one box = 15/12
width of one box = 1.25 inches
I'm pretty sure the above fractions are equivalent because if you reduce 5s/15t then it equals s/3t.
Answer:
The answer is:
r<8
