Answer:
180
Step-by-step explanation:
12x15=180 simple
Answer:
3 cm
Step-by-step explanation:
First, find the volume of the cone.
V = 
r²h
V =
(3.14)(9)(12)
V = 113.04
This means the sphere is also 113.04
Use the formula V = 
r³
113.04 =
(3.14)r³
113.04 = 4.19r³
26.98 = r³
3 ≈ r
Answer:

Step-by-step explanation:
ST = w + 6,
PR = w
From the diagram given, we can deduce that PR is the midsegment of ∆QST. Therefore, according to the midsegment theorem:
PR = ½ of ST
Plug in the values into the equation and solve for w.

(distributive property of equality)
(subtraction property of equality)
(multiplication property of equality)

(subtraction property of equality)

Divide both sides by -1

Explanation:
We can find the slope by solving for y.
3x +2y +7 = 5x +3y +10
-2x -3 = y . . . . . . . . . . . . . add -5x-10-2y to both sides of the equation
In this form, the slope (m) is the coefficient of x, -2. Hence m = -2.

<em>Alternate solution</em>
A graph of the equation shows it has an x-intercept of -1.5 and a y-intercept of -3. The slope (m) is then "rise" divided by "run", or ...
m = rise/run = -3/1.5
m = -2
