Triangle M was dilated by a scale factor of 1.2 to form triangle M. How does the area of triangle M'

GrogVix [38]

Answer:

The area of triangle M is 1.44 times the area of triangle M.

Step-by-step explanation:

From Geometry we remember that the area formula of the triangle is:

$A = \frac{1}{2}\cdot b\cdot h$ (1)

Where:

$b$ - Base of the triangle, dimensionless.

$h$ - Height of the triangle, dimensionless.

$A$ - Area of the triangle, dimensionless.

The dillation of the triangle by a scale factor means that:

$A' = \frac{1}{2}\cdot b'\cdot h'$ (2)

$b' = k\cdot b$ (3)

$h' = k\cdot h$ (4)

Where:

$b'$ - Dilated base of the triangle, dimensionless.

$h'$ - Dilated height of the triangle, dimensionless.

$A'$ - Dilated area of the triangle, dimensionless.

$k$ - Dilation factor, dimensionless.

If we know that $k = 1.2$ , then the area formula for the dilated triangle is:

$A' = \frac{1}{2}\cdot (k\cdot b)\cdot (k\cdot h)$

$A' = k^{2}\cdot \frac{1}{2}\cdot b\cdot h$

$A' = k^{2}\cdot A$

Therefore, the area of triangle M is 1.44 times the area of triangle M.

Please help me i have no clue what the answer is :?

Nadusha1986 [10]

Answer:

1. Yes

2. They could change the 60° angle into a different one.

Step-by-step explanation:

1. Two triangles are the same if they share two side lengths with the same angle between them.

2. Since the triangles are equal if they share two side lengths with the same angle between them, if they changed the angle between 3 and 5, it'd no longer be the same triangle.

You are dealt two cards without replacement what is the probability the first card is one of 4 twos and second is 4 tens in a de

Ilia_Sergeevich [38]

A = drawing a two card
B = drawing a ten card

P(A) = 4/52 = 1/13
P(B|A) = P(A and B)/P(A)
P(A)*P(B|A) = P(A and B)
P(A and B) = P(A)*P(B|A)
P(A and B) = (1/13)*(4/51)
P(A and B) = 4/663
P(A and B) = 0.006033

The answer as a fraction is exactly 4/663
The answer in decimal form is approximately 0.006033
