The answer is C: first add 2 both sides then divide both sides by -5.
Answer:
126mm
Step-by-step explanation:
To find the diameter of the circle = circumference divided by pi = 56.52/3.14=18mm.
There are 4 circles = 18mmx4=72mm
Add on the 3x strips = 72+(18x3) = 126mm.
Hope this helps
Answer:
Thus, the value of x = -36 when y = 15
Step-by-step explanation:
We know that if y varies directly with x, we can express the relationship such as
y ∝ x
y = kx
k = y/x
where 'k' is called constant of variation.
Given
y = -5
x = 12
Using the equation
k = y/x = -5/12
Thus, the value of k = -5/12
Finding x when y = 15
y = 15
k = -5/12
substituting y = 15 and k = -5/12 in the equation
y = kx
15 = -5/12 (x)
15×12 = -5x
180 = -5x
divding both sides by -5
-5x/-5 = 180/-5
x = -36
Thus, the value of x = -36 when y = 15
Answer:
Step-by-step explanation:
The formula of a volume of a cylinder:
r - radius
H - height
We have the height H = 3ft and the radius r = 4ft. Substitute:
