8 0

Answer:

21%

Step-by-step explanation:

Formula for this type of problem is

\frac{84}{400} = \frac{x}{100}

cross multiply

8400 = 400x

divide by 400

8400 = 400x

/400   /400

21 = x\\

plug 21 into the original equation

\frac{84}{400} = \frac{21}{100}

simplify

\frac{84}{100} = .21

.21 can be represented as 21%

A triangle has vertices at L(2, 2), M(4,4), and N(1,6).
mr Goodwill [35]

Answer:

The rule for the transformation is (x, y) (-x, -y).

The coordinates of L'are (-2,-2).

The coordinates of N'are (-1,-6).

Step-by-step explanation:

Given

L = (2,2)

M = (4,4)

N = (1,6)

Ro=180

Required

Select three options

The rule to this is:

(x,y) \to (-x,-y)

So, we have:

L = (2,2)

L' =(-2,-2)

M = (4,4)

M =(-4,-4)

N = (1,6)

N' = (-1,-6)

All you have to do is divide 40 by five and you've got your answer. I don't have the required diagram, but that would basically mean that the average lifespan of a guinea pig is about eight years, which is being generous in reality (they usually live for about 4-8 years in real life).
