Answer:
2044 cubic inches
Step-by-step explanation:
The amount of concrete required is the larger volume MINUS the smaller volume.
Note: Volume of cube = s^3 where s is the side length
Larger Volume = s^3 = 15^3 = 3375
and
Smaller Volume = s^3 = 11^3 = 1331
Hence, amount of concrete needed to make 1 planter = 3375 - 1331 = 2044 cubic inches
Answer: Area: 99cm Perimeter: 40cm
Step-by-step explanation:
To find the area, you would multiply 9cm by 11cm because the formula for area is length times width. To find the perimeter, you add all the sides, which would mean you add 9 + 9 + 11 + 11, making the perimeter 40cm.
Answer:
y + 2 = ⁶/₅(x - 5) {the point-slope form of the equation}
y = ⁶/₅x - 8 {the slope-intercept form of the equation}
6x - 5y = 40 {the standard form of the equation}
Step-by-step explanation:
The point-slope form of equation is: y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope.
m = ⁶/₅
(5, -2) ⇒ x₀ = 5, y₀ = -2
So, the point-slope form of the equation:
y + 2 = ⁶/₅(x - 5)
Therefore:
y + 2 = ⁶/₅x - 6 {subtract 2 from both sides}
y = ⁶/₅x - 8 ← the slope-intercept form of the equation
-⁶/₅x + y = - 8 {multiply both sides by (-5)}
6x - 5y = 40 ← the standard form of the equation
