Answer:
A
Step-by-step explanation:
if you did 6+3=9
8x(9)=72
"27+45=72"
Diameter = 40
Circumference is about 125.66
Area is about 1256.64
Answer:
3/2
Step-by-step explanation:
Because the problem tells you that the two triangles are similar, the value of a/b would be equivalent for both triangles. The fact that they are right triangles also indicates which sides are which in case the image was not drawn to scale. A is proportional to 2.1 and b is proportional to 1.4. So a/b= 2.1/1.4. This can reduce itself to 3/2 because both are divisible by .7
Answer:
B. y - 0 = -⅓(x + 2)
Step-by-step explanation:
First, find the slope of the line using two points in the line, (-5, 1) and (-2, 0):
Slope (m) = ∆y/∆x = -⅓
To find the equation in point-slope form, substitute (a, b) = (-2 0), and m = -⅓ into y - b = m(x - a)
Thus:
y - 0 = -⅓(x -(-2))
y - 0 = -⅓(x + 2)
Given :
After 4 days, a plant is measured to be 10 inches tall.
Later, after a total of 20 days, then height is measured to be 18 inches.
To Find :
The rate of growth for the plant.
Solution :
We know, rate is given by :
Therefore, rate of increase of height is 0.5 inch/day .
Hence, this is the required solution.
