Polygon Y is a scaled copy of Polygon X using a scale factor of 1/3 Polygon Y's area is what fraction of Polygon X's area?

Answers

Answer:

1/9. Because the area is measured in units squared, then you have to square 1/3 which is 19th.

Step-by-step explanation:

The area is measured in squared units. You have to square 1/3 which is 1/9. (1)/(3) ^2= (1)/(3) ((1)/(3))

Answer:

1/9

Step-by-step explanation:

SideY/sideX = ⅓

AreaY/AreaX = (sideY/sideX)²

= (⅓)²

AreaY/AreaX = 1/9

Answer:

x = -4/3

Step-by-step explanation:

2(x-1) +3(1-2x) = 5-x

Distribute

2x-2 +3 -6x = 5-x

Combine like terms

-4x +1 = 5-x

Add 4x to each side

-4x+4x +1 = 5-x+4x

1 =5+3x

Subtract 5 from each side

1-5 =5-5 +3x

-4 = 3x

Divide each side by 3

-4/3 = 3x/3

-4/3 =x

Answer:

1-5 =5-5 +3x

-4 = 3x

Divide each side by 3

-4/3 = 3x/3

-4/3 =x

The legs of a right triangle are 4 units and 7 units. What is the length of the hypotenuse?A. square root 33 units
B. square root 65 units
C. 33 units
D. 65 units

Answers

Answer:

Correct option is:

B. square root 65 units

Step-by-step explanation:

Pythagorean theorem states that the square of hypotenuse is equal to the sum of squares of the legs of the right angled triangle.

Here, we are given that:

The legs of a right triangle are 4 units and 7 units.

By Pythagoras theorem

Hypotenuse²=4² +7²

                     = 16+49

                     = 65

⇒ Hypotenuse= √(65)

Hence, Correct option is:

B. square root 65 units
the square root of 65 units
