Which of the following pairs show(s) triangles that are similar but not congruent?

Answer:

D. D₂ (∆XYZ)

Step-by-step explanation:

Dₙ = (x,y) → ((n)x, (n)y)

_________________

X = (-1, 2).

Y = (2, -1).

Z = (-2, -1).

_________

Dₙ ∆XYZ:

X(-1, 2) → X'(-2, 4)

Y(2, -1) → Y'(4, -2)

Z(-2, -1) → Z'(-4, -2)

______________

-2 / -1 = 2, 4 / 2 = 2.

4 / 2 = 2, -2 / -1 = 2.

-4 / -2 = 2, -2 / -1 = 2.

_______________

D₂ = (x,y) → ((2)x, (2)y).

X(-1, 2) → ((2)(-1), (2)(2)) = X'(-2, 4)

Y(2, -1) → ((2)(2), (2)(-1)) = Y'(4, -2)

Z(-2, -1) → ((2)(-2), (2)(-1)) = Z'(-4, -2)

Answer:

[tex]x + \frac{5}{3}-x - \frac{3}{2} = \frac{1}{6}[/tex]

Step-by-step explanation:

Given

[tex]x + \frac{5}{3}-x - \frac{3}{2}[/tex]

Required

Solve

[tex]x + \frac{5}{3}-x - \frac{3}{2}[/tex]

Collect like terms

[tex]x + \frac{5}{3}-x - \frac{3}{2} = x -x+ \frac{5}{3} - \frac{3}{2}[/tex]

[tex]x + \frac{5}{3}-x - \frac{3}{2} = \frac{5}{3} - \frac{3}{2}[/tex]

Take LCM

[tex]x + \frac{5}{3}-x - \frac{3}{2} = \frac{10 -9}{6}[/tex]

[tex]x + \frac{5}{3}-x - \frac{3}{2} = \frac{1}{6}[/tex]

Answer:

Surface area of cylinder = 24π

Step-by-step explanation:

Given:

Base diameter = 4 yd

So Radius = 4 / 2 = 2 yd

Height = 4 yd

Find:

Surface area of cylinder

Computation:

Surface area of cylinder = 2πr(h+r)

Surface area of cylinder = 2π(2)(4+2)

Surface area of cylinder = 2π(2)(6)

Surface area of cylinder = 24π

Step-by-step explanation:

Answer:

Step-by-step explanation:

All the sides of a square are equal, so:

12x - 5 = 7x + 4

12x - 7x = 4 + 5

5x = 9

x = 9/5

Answer: 17, 19, 21

Step-by-step explanation:

Three consecutive odd numbers: x, x+2, x+4 (since odd numbers occur every other number)

Just to show you that the numbers are x, x+2, and x+4, just say x is 13 then x+2 is 15 and x+4 is 17 (3 consecutive odd numbers)

Now the second equation:

3x = 2(x+4) + 9

three times smallest number (which is x) is equal to 2 times the largest number (x+4) plus 9

Now solve

3x = 2(x+4) +9

3x = 2x + 8 + 9

3x = 2x + 17

x = 17

x+2 = 19

x+3 = 21

Answer: $5.33

Step-by-step explanation:

Bliss was able to collect $18 in total.

Out of this total, she received a $2.00 bronze star donation and the rest were 3 Silver star donations.

This means that the 3 equal silver star donations added up to:

= 18 - 2

= $16.00

This means that each silver star donation was:

= Amount in total / Number of silver stars

= 16 / 3

= $5.33

Answer:

61.25

Step-by-step explanation:

The of cubic units which hat occupies having a radius of 3 inches and a height of 6.5 inches is 61.26 cubic inches.

Volume of cone is the amount of quantity, which is obtained it in the 3 dimensional space.

The volume of the cone can be given as,

[tex]V=\dfrac{1}{3}\pi r^2h[/tex]

Here, (r) is the radius of the base of the cone and (h) is the height of the cone.

A cone-shaped party hat has a radius of r=3 inches and a height of h=6.5 inches. The amount of cubic units it occupies is equal to the volume of hat.

Thus, put the values in the above formula as,

[tex]V=\dfrac{1}{3}\pi (3)^2(6.5)\\V=\dfrac{1}{3}\pi (3)^2(6.5)\\V=61.26\rm\; in^3[/tex]

Thus, the of cubic units which hat occupies having a radius of 3 inches and a height of 6.5 inches is 61.26 cubic inches.

Answer:

2 5/14 yards

Step-by-step explanation:

Area of the rectangular floor = Length * Width

Given

Area = 8 1/4 square yards

width = 3

1/2 yards

Required

Length

Length = Area/width

Length = (8 1/4)/(3 1/2)

Length = 33/4 ÷ 7/2

Length = 33/4 * 2/7

Length = 33/14

length = 2 5/14 yards

This gives the required length
