Answer:
7x-6
Step-by-step explanation:
x+3+3x-18+3x+9 (Add like terms)
(x+3x+3x) (3-18+9) (solve) ( x is the same as 1x)
(7x) (-6)
7x-6
Answer:
Step-by-step explanation:
So we have:
And we want to solve for π.
First, divide both sides by h:
Now, divide both sides again by r²:
And this is our answer :)
Answer:
1386 in³
Step-by-step explanation:
Volume of the composite cone = volume of a hemisphere + volume of a cone
=>Find the volume of cone
Volume of cone = ⅓πr²h
π = 3.142
r = 7 in
h = =√(15² - 7²) [using Pythagorean theorem to solve for height given the slant height and radius]
h = √(225 - 49)
h = √176 ≈ 13 in
Volume of cone = ⅓*3.142*7²*13
= ⅓*2001.454 ≈ 667 in³
=>Find volume of hemisphere.
Volume of hemisphere = ½*volume of sphere = ½*4/3πr³ = ⅔πr³
π = 3.142
r = 7 in
Volume = ⅔*3.142*7³ ≈ 719 in³
<em>Volume of composite figure = 667+719 = 1386 in³</em>
Answer:
no, it is 38.5
Step-by-step explanation:
you have to add up the two numbers that are in the middle then divide it by two since there isn't just one number in the middle.
The cities are 14.7 inches apart on the map.
An inch on the map is 10 miles on the ground. That is what a scale of 1 in : 10 miles means.
If a distance is 147 miles on the ground therefore, on the map it will be:
= Distance on map / conversion factor
= 147 / 10
= 14.7 inches
The distance between the two cities on the map is 14.7 inches.
