Answer:
<u>The volume of a mound of salt-sand mixture is 589.05 feet ³ or 589.05 cubic feet.</u>
Step-by-step explanation:
1. Let's check the information given to resolve the question:
Diameter of a mound of the mixture = 15 feet
Height (h) of the mound of the mixture = 10 feet
How much salt-sand mixture is there?
2. Let's find the volume of a mound of mixture with a conical shape:
For doing that, we need to use the volume formula of a cone.
It's: 1/3 * π * r² * h
Replacing with real values, we have:
1/3 * 3.1416 * 7.5 ² * 10 (Diameter = 15, so radius = Diameter/2 = 15/2 = 7.5)
Volume = 1/3 * 3.1416 * 56.25 * 10
Volume = 1/3 * 3.1416 * 562.5 (56.25 * 10 = 562.5)
<u>Volume = 187.5 * 3.1416 = 589.05 feet ³ or 589.05 cubic feet.</u>

Step-by-step explanation:
Answer:
A number (x) is 14.3
Step-by-step explanation:
You can write the problems like this and solve starting with z to x
x - 15 = y (15 was subtracted from a number)LAST HERE
x = 15 + -0.7
x = 14.3
y / 0.7 = z (and that difference was then divided by 0.7.)THEN HERE
y = -1 x 0.7
y = -0.7
3z = -3(After which, that quotient was multiplied by 3. The resulting product was -3.) START HERE
z = -3 / 3
z = -1
CHECK
14.3 - 15 = -0.7 -0.7 / 0.7 = -1 3 x -1 = -3
