In the figure below, the triangles are similar. Find the ratio of their areas from larger to smaller.

Answers

Answer 1

Area of larger triangle is A1
21:14=x:8
x=21•8/14
x=168/14
x=12
x=base of triangle
A2=h•b/2
21^2=6^2+h^2
441=36+h^2
h^2=441-36
h^2=405
h= √405
h=20.12

A1=12•20.12/2
A1=6•20.12
A1=120.72

Area of smallest triangle is A2
A2=b•h/2
h=?
14^2=4^2+h^2
196=16+h^2
h^2=196-16
h^2=180
h= √180
h=13.42
A2=8•13.42/2
A2=4•13.42
A2=53.68

Ratio 120.72:53.68
Ratio=2.25

Which expression is equivalent to 64y18 – 1000z6?

Answers

Answer:

8 * (2y⁶ - 5z²) ( 4y¹² +10 y⁶z² + 25z⁴)

Step-by-step explanation:

64y¹⁸ – 1000z⁶ = 8 * (8y¹⁸ - 125z⁶) = 8 * ((2y⁶)³ - (5z²)³)

= 8 * (2y⁶ - 5z²) ( 4y¹² +10 y⁶z² + 25z⁴)

Find the surface area, given that the area of each hexagon is 166 square feet.

Answers

Answer:

Step-by-step explanation:

The ratio of the perimeters of two squares is 2:3. If the
area of the larger square is 324 square feet, what is the length, in feet, of the side of the smaller square?

Answers

2:3 would be the right feet.

Where the above ratio are given, the length of the side of the smaller square is approximately 14.7 feet.

How to compute the above

The area of a square is calculated by squaring the length of its side. Given that the area of the larger square is 324 square feet, we have:

(3/2)x² = 324

To solve for x, we can rearrange the equation and take the square root of both sides -

x² = (324 * 2) / 3

x² = 216

x ≈ √216

x ≈ 14.7

Hence , the length of the side of the smaller square is approximately 14.7 feet.

Answers

Answer:

A certain field is a rectangle with a perimeter of 818 feet. The length is 175 feet more than the width. Find the width and length of the rectangular field.

Answers

9514 1404 393

Answer:

width 117 feetlength 292 feet

Step-by-step explanation:

Let w represent the width of the field. Then w+175 is its length. The perimeter is ...

P = 2(L+W)

818 = 2((w+175) +w) . . . . . fill in given values

818 = 4w +350 . . . . . . . . . simplify

468 = 4w . . . . . . . . . subtract 350

117 = w . . . . . . . . divide by 4

w+175 = 292 . . . . find the corresponding length

The width of the field is 117 feet; the length is 292 feet.

Answer:

4990

Step-by-step explanation:

638 x 5 = 3190

There is already a population of 1800, so then you add 3190 and 1800 to get 4900. The reason you add these numbers is because the population grows by 638 every year. They want to know how much it will grow in 5 years. You you multiply n (number) by y (year) to get t ( total).

Which number is a perfect cube?
A. 8
B. 9
C. 16
D. 25

Answers

C. 16
2^3 = 16
2x2=4
4x2=8
8x2=16

8 is a perfect cube number. So, option A.) is correct.

A number is said to be a perfect cube if it can be multiplied by itself three times. X must equal [tex]y^3[/tex] if it is a perfect cube of Y. As a result, a natural integer, not a fraction, is obtained when we take the cube root of a perfect cube. Therefore, [tex]3\sqrt{x}[/tex] equals y.

Let, a be a integer number then for a number to be perfect cube

Number= [tex]a^3[/tex]..............................................where a is integer number

8= [tex]a^3[/tex]

So, a=2

9= [tex]a^3[/tex]

No, integer value exist, whose cube is 9.

16= [tex]a^3[/tex]

No, integer value exist, whose cube is 16.

25= [tex]a^3[/tex]

No, integer value exist, whose cube is 25.

Thus, 8 is a perfect cube number. So, option A.) is correct.
