Answer:
a. 38.5
Step-by-step explanation:
The triangles are similar. That means that the ratios are the same.
x/14 = 11/4
x/31.5 = 11/9
Let's use the top one
x/14 = 11/4
4x/14 = 11
4x = 154
x = 38.5

The volume of a cone, V , varies jointly with its height, h , and the square of its
radius, r . If k is the constant of proportionality, which of the following equations
represents the correct relationship between volume, radius, and height?
An equation is formed of two equal expressions. The equation that represents the correct relationship between volume, radius, and height is V=khr².
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given the volume of a cone, V varies jointly with its height, h, and the square of its radius, r. Therefore, the relationship can be written as,
V ∝ h(r²)
Also, k is the constant of proportionality, therefore, the equation now can be written as,
V = k×h×r²
Hence, the equation that represents the correct relationship between volume, radius, and height is V=khr².

x=10 y=15
x= 30 y=25
x=16 y=21
x= 32 y= 26
Answer:
the last one
Step-by-step explanation:
32+26=58
32-26=6
Answer:
The first number is 32 and the second is 26
Step-by-step explanation:
Let the two numbers be represented by x and y
1) x + y = 58
2) x - y = 6
x = 6 + y, we'll use put this in the first equation.
x + y = 58
6 + y + y = 58
6 + 2y = 58
2y = 58 - 6
2y = 52
2. 2
y=26, now let's find x, again use the first equation
x + y = 58
x + 26 = 58
x = 58 - 26
x = 32

The height, h, in feet of a golf ball above the ground after being hit into the air is given by the equation, h = -16t 2 + 64t, where t is the number of seconds elapsed since the ball was hit. How many seconds does it take for the golf ball to hit the ground?
It will take ---------
seconds for the ball to hit the ground??
Answer:
Step-by-step explanation:
It will hit the ground when height is equal to zero.
-16t^2+64t=0
-16t(t-4)=0
t=4 seconds
The other persons right,
it will take 4 seconds for the ball to hit the ground.
