Answer:

The prime factorization is 3*3*5

Step-by-step explanation:

IN order to find this, start by dividing by the lowest non-one number that goes in evenly. Since 2 does not go in, divide 45 by 3.

45/3 = 15

Now that we have 15, we can do the same. 3 is again the right number.

15/3 = 5

And since 5 is a prime number, then take all the numbers you divided by and the 5 to create the prime factorization.

3*3*5

How do I get the answer for 1 1/2 x 3 x 1 1/9

Mekhanik [1.2K]

$\boxed{1 \frac{1}{2}\times 3 \times 1 \frac{1}{9}=5}$

<h2>Explanation:</h2>

in this problem we have the following expression:

$1 \frac{1}{2}\times 3 \times 1 \frac{1}{9}$

So here:

$1 \frac{1}{2} \ and \ 1 \frac{1}{9} \ are \ written \ as \ mixed \ fractions$

Let's convert them as improper fractions:

$1 \frac{1}{2}=1+\frac{1}{2}=\frac{1\times 2+1}{2}=\frac{3}{2} \\ \\ 1 \frac{1}{9}=1+\frac{1}{9}=\frac{1\times9 +1}{9}=\frac{10}{9}$

Rewriting our expression:

$\frac{3}{2}\times 3 \times \frac{10}{9}=\frac{3\times 3 \times 10}{2\times 9}=\frac{90}{18}=5$

The diagrams show triangular figures

The first figure has 1 dot

The second has 1 + 2 = 3 dots

The third has 3 + 3 = 6 dots

The fourth has 6 + 4 = 10 dots

Note the pattern is + 2 , + 3, + 4

This composite figure consists of a right triangle and semicircle

The area of a triangle is: 1/2(bh)

The area of a semicircle is 1/2(pi)(r²)

Plug in the values:

1/2( 12)(8)

=48

1/2(3.14)(4²)

=25.12

25.12+48=73.12
