Answer:
8.5 units
Step-by-step explanation:
(-1, 1) squared + (7,4) squared = formula
Distance 8.5 is rounded to the nearest 10
Answer:
Step-by-step explanation:
1st question: perimeter is 34 m; area is 44m^2
2nd question: perimeter: 20.3 ft; area is 13
3rd question: 32 units^2 (I might be wrong)
4th question: 105 in^2
The solution would be like this for this specific problem:
Volume of a cylinder = pi * r^2 * h
Volume of a cone = 1/3 * pi * r^2 * h
Total Height = 47
Height of the cone = 12
Height of the cylinder = 35
If the top half is filled with sand, then:
volume (sand) = pi * 4^2 * 36
volume (cone) = 1/3 * pi * 4^2 * 12
Total volume = 1960.353816 cubic millimeters
353816 / (10 * pi) = 62.4 seconds.
It will take 62.4 seconds until all of the sand has dripped to the bottom of the hourglass.
Answer:
To solve for y, you want to use the distributive property
First you want to distribute the 8 through the 3y-5 and the 9 through the y-5
8(3y-5)= 24y-40
9(y-5)= 9y-45
24y-40=9y-45 (get the x on one side, so first add 40 to each side)
24y=9y-5 (now subtract 9y to each side)
15y=-5 (divide both sides by 15)
y= -5/15= -1/3
Hope this helps ;)
Answer:
m=-1
Step-by-step explanation:
9m+13 =4
Subtract 13 from each side
9m+13-13 =4-13
9m = -9
Divide each side by 9
9m/9 = -9/9
m = -1
