Answer:
You can identify whether your answer is correct or not and/or easily solve for an answer.
Step-by-step explanation:
To see if things make sense, estimating an answer can give you that clarification. More so, in high school geometry, you tend to get lots of decimals and radicals and all sorts of crazy numbers so estimation can really help. I hope that helps you. If that was not what you were looking for please feel free to ask.
Answer:
Dividing by 8 on both sides
Step-by-step explanation:
Answer:
the answer to the whole equation is x=30.
Step-by-step explanation:
do 2/3(2) and -1/2(3)
4/6x and -3/6x
add the -3/6x to the other side
7/6x or 1 and 1/6x=5
times both by 6
x=30
<span>The answer is: 2. 11
Crowbar is a Class A lever
Therefore the mechanical advantage of the crowbar can be given by either:
MA = Output distance/Input distance
OR
MA = Output force/Input force
Since, the question gives only the force, we can use the second formula.
MA = Output force/ Input Force
= 330 N / 30 N
= 11</span>
Answer:
Step-by-step explanation:
The area to be resurfaced is the area of the
whole circle including garden and lanes minus
the area of the garden.
Area of a circle is (pi)r2
radius of garden is (1/2)diameter = 8 m
Garden area: (pi)82 = 64(pi) m2
Diameter of garden plus traffic lanes is
16 + 2(6) because we add 6 m to both sides
of the diameter of the garden.
Full diameter = 16+12 = 28 m
Full radius = 28/2 = 14 m
Full area: (pi)142 = 196(pi) m2
Area to be resurfaced:
196(pi) - 64(pi) = 132(pi) m2 ≅ 415 m2
