Percent means per 100.
Per means divided by.
So you can change a number by multiplying it by 1. Anything over itself is 1 (except zero but that doesn't matter right now)
So multiply .6 by 100/100
So you get 60/100
or 60 per 100
or 60%.
So basically, just multiply by 100 and add the % sign!
The triangle at top has a perimeter of 5, 12, and 13. The square has a perimeter of 29, 12, 29, and 12. If you add all those up you get 112
Answer:
Step-by-step explanation:
Isolate x on one side of the equation.
2(-2x-4) ← (Expand by using with distributive property.)
<u><em>DISTRIBUTIVE PROPERTY</em></u>
⇒ A(B+C)=AB+AC
⇒ A(B-C)=AB-AC
A=2
B=(-2x)
C=4
2(-2x)-2*4
-2*2x-2*4
-2*2x-2*4 (Solve.)
-2*2-2*4=-4x-8
Rewrite the equation problem.
10-x=-4x-8
10-x-10=-4x-8-10 (Subtract 10 from both sides.)
Solve.
-x=-4x-18
-x+4x=-4x-18+4x (Then, add 4x from both sides.)
3x=-18 (Solve.)
3x/3=-18/3 (Divide by 3 from both sides.)
-18/3 (Solve & Simplify.)
-18/3=-6
X=-6
Therefore, the correct answer is x=-6.
The answer is A
A Parallelogram is a shape with 4 sides that has two pairs of parallel sides. The opposite sides must have equal length. This is accurate for this shape.
A Rectangle is a shape with 4 sides that has four right angles. This is accurate for this shape.
A rhombus is a shape with 4 sides of equal length. This is not accurate for this shape.
A square is a shape with 4 sides of equal length and four right angles. This is not accurate for this shape.
Step-by-step explanation:
2 m corresponds to 0.4 cm on a blueprint.
so,
2 m / 0.4 cm = 200 cm / 0.4 cm
our fun the point of view of the blueprint
0.4 cm / 200 cm
the scale on a map or blueprint is usually normed to one unit on the blueprint :
0.4/200 × f/f = 1/(200×f)
0.4 × f = 1
f = 1/0.4 = 2.5
so, our scale is
(0.4 × 2.5) / (200 × 2.5) = 1 / 500
that means 1 cm on the blueprint corresponds to 500 cm or 5 m in reality.
