Answer:
Z=0.8
Step-by-step explanation:
Step-by-step explanation:
Combine the opposite terms
2z+2+4z=7
Add
2z and 4z
6z+2=7
Move all terms not containing z to the right side of the equation.
Subtract 2 from both sides of the equation.
6z=7−2
6z=5
Divide each term:
6z/6 = 5/6
Decimal Form:
z=0.8
Hey there!
Given that this flower bed is circular, it can be assumed that it's a cylinder. In this problem, we need to use the equation for the volume of a cylinder:
V = π r² h
Since we just need to find the area that the mulch will take up, we'll use that given measurement of 4 inches in place of the actual height of the flower garden. Since we need the radius, all we have to do is divide the 12 inch diameter measurement in half to get a radius of 6 inches. Usually for these problems, they'll tell you to use 3.14 for pi instead of the full pi number, so we'll just use that to make things easier.
V = π (6)² (4)
V = π (36)(4)
V = π (144)
V = 452.16
The volume of the mulch needed will be 452.16 in³.
Hope this helped you out! :-)
It is most likely to be 7.4cm because that is the closest because the hypotenuse length is the longest so side A wouldn't be as small as 2.5cm ??? This is just an estimate ;)
Answer:
29.3 feet
Step-by-step explanation:
Okay I don't know the equation to put it in, but all you need to do is add the two values together.
12.4 + 16.9 = 29.3 feet
