Okay. 10×5=50cm^2 is the area of the rectangle
The height of the triangle is (18-10)=8cm
So (8×5)÷2=20cm^2
50+20=70cm^2 is the area of the composite shape

If a/b = 4/3 and b/c = 2/3, what is a,b, and c?
kaheart [24]

Answer:

.

Step-by-step explanation:

\frac{a}{b}  =  \frac{4}{3}

\frac{b}{c}  =  \frac{2}{3}

to give b from both equation the same value

\frac{a}{b}  =  \frac{4}{3}  \times   \frac{2}{2}  =  \frac{8}{6}

\frac{b}{c}  =  \frac{2}{3}  \times  \frac{3}{3}  =  \frac{6}{9}

a:b:c = 8:6:9

a = 8

b = 6

c = 9

Graph the image using the given transformation
Hunter-Best [27]

The triangle KLM is rotated about origin by 90 degrees to form the triangle K'L'M'.

<h3>What is a transformation of geometry?</h3>

A spatial transformation is each mapping of feature shapes to itself, and it maintains some spatial correlation between figures.

Rotation does not change the size and shape of the geometry.

The triangle KLM is rotated about origin by 90 degrees to create the triangle K'L'M'.

The diagram is given below.

More about the transformation of geometry link is given below.

Vsevolod [243]
In order to find a percentage, you divide the sample by the total amount.

For example: Tess has 3 cookies out of the total amount of 9. 3/9 = 33.3%

Find at least 3 numbers that are palindromes and have square roots that are palindromes
Artemon [7]

Hey there!

Palindromes are numbers that can be written the same way backwards, such as 101 and 12321. You're looking for some numbers which are palindromes, and so are their square numbers.

Alright, I'll give you four of those:

  1. 121 is a palindrome, and its square root is 11, both palindromes. 11 x 11 = 121
  2. 484 is a palindrome, and its square root is 22, both palindromes. 22 x 22 = 484
  3. 10201 is a palindrome, and its square root is 101, both palindromes. 101 x 101 = 10201
  4. 12321 is a palindrome, and its square root is 111, both palinromes. 111 x 111 = 12321

Hope this helps!
