Each pair of figures below is similar. Find the lengths of all unknown sides

lions [1.4K]

Answer:

a) w = 8; y = 5.25

b) x = 10; z = 7.2

Step-by-step explanation:

a) Dimensions on the smaller figure are FA/F'A' = 3/4 times those on the larger figure.

6 = (3/4)w

w = 24/3 = 8

y = (3/4)·7 = 21/4 = 5.25

b) Dimensions on the smaller figure are ER/E'R' = 9/15 = 3/5 times those on the larger figure.

6 = (3/5)x

x = 30/3 = 10

z = (3/5)12 = 36/5 = 7.2

20. Determine the following product. 5g(-3g²h - 7g + 9)

soldier1979 [14.2K]

Distribute 5g to all of the terms in parentheses:

$5g \times -3g^2h = -15g^3h$
$5g \times -7g = -35g^2$
$5g \times 9 = 45g$

$-15g^3h - 35g^2 + 45g$

The answer is A.

An architect creates a scale model of a building with a scale of 3 inches =11 feet of the actual width of the building is 121 fe

Tomtit [17]

Answer:

The width of the scale model is 33 inches.

Step-by-step explanation:

This question is solved making a relation with the scale model.

In the scale, 3 inches are worth 11 real feet.

The actual width of the building is 121 feet, so we find it's scale by a rule of three.

3 inches - 11 feet

x inches - 121 feet

$11x = 121*3$

Simplifying by 3, both sides

$x = 11*3 = 33$

The width of the scale model is 33 inches.

Solve for x..................

Lostsunrise [7]

7x - 9 < 12
7x < 12 + 9
7x < 21
x < 21/7
x < 3

1/4x + 8 > 11
1/4x > 11 - 8
1/4x > 3
x > 3 * 4
x > 12

solution : x < 3 or x > 12
