(60,4)(120,8)
slope = (8 - 4) / (120 - 60) = 4/60 = 1/15 <== the constant of proportionality is the slope
Answer:
270 first question's answer
Step-by-step explanation:
Solution at attachment box
Total surface area of cuboid is = 12x18x2 + 10x12x2 +18x10x2
=432+240+360
=1032
Surface of the 1 cube =2x2x2 = 8
Surface of the all cubes = 8x270 = 2160
Consecutive means right behind each other basically.
1,2,3,4,5 are consecutive numbers because they are in order.
the numbers got 135, 136, 137, 138, 139, 140
137 lies between 136 and 138.
136 and 138 is your answer
The slope-intercept form: y = mx + b
m - a slope
b - y-intercept
8x - 3y = 10 |subtract 8x from both sides
-3y = -8x + 10 |divide both sides by (-3)
y = 8/3 x - 10/3
Answer:
The slope: m = 8/3
The y-intercept: b = -10/3
This is a right triangle (you can confirm by using Pythagorean Theorem: 15² + 36² = 39²)
A = 
A = 
= 15 * 18
= 270
Answer: 270 cm²
