Answer:

226.285 square

Step-by-step explanation:

Given:

The radius of a circular sign is 12 inches.

Equal parts of the sign are painted red and yellow.

Question asked:

How many square inches are painted each​ color?

Solution:

Here given that <u> a circular sign is divided into two equal parts </u>and one part is painted with red and other with yellow and we have to calculate the area of each color:

We will find area of semicircle of each color:

Area\ of\ semicircle =\frac{\pi x^{2}}{2}

                               =\frac{\frac{22}{7}\times12\times12 }{2} \\ \\ =\frac{\frac{3168}{7} }{2} \\ \\ =\frac{452.57}{2} \\ \\= 226.285\ square\ inches

Thus, 226.285 square inches are painted each color.

17n + 4n- 4= 122<br><br> how do i solve for n?
Leokris [45]

Answer:

n = 6

Step-by-step explanation:

17n + 4n - 4 =122

combine like terms  17n & 4n

21n - 4 = 122

21n - 4 + 4 = 122 + 4

21n = 126

21n / 21 = 126 / 21

n = 6

Write the algebraic expression for... 16 less than a number n
jarptica [38.1K]

Answer: n-16

Step-by-step explanation:

The algebraic expression for 16 less than a number n is thesame thing as subtracting 16 from n which will be represented as: n - 16.

Therefore, the algebraic expression for 16 less than a number n will be = n - 16

Factor completely 81x^8-1
marysya [2.9K]

The complete factorized form for the given expression is \left(9 x^{4}+1\right)\left(3 x^{2}+1\right)\left(3 x^{2}-1\right)

<u>Step-by-step explanation:</u>

Step 1: Given expression:

              81 x^{8}-1

Step 2: Trying to factor as a Difference of Squares

Factoring 81 x^{8}-1

As we know the theory that the difference of two perfect squares, A^{2}-B^{2}  can be factored into (A+B) (A-B)

from this, when analysing, 81 is the square of 9, x^{8} is the square of x^{4}. Hence, we can write the given expression as,

            \left(9 x^{4}\right)^{2}-1^{2}

By using the theory, we get

           \left(9 x^{4}+1\right)\left(9 x^{4}-1\right)

Again, we can further factorise the term \left(9 x^{4}-1\right)

9 x^{4} is the square of 3 x^{2}. Therefore, it can be expressed as below

           \left(3 x^{2}+1\right)\left(3 x^{2}-1\right)

Now, we can not factorise further the term \left(3 x^{2}-1\right). Because it will come as \sqrt{3} x (3 is not a square term). Thereby concluding that the complete factorisation for the given expression is \left(9 x^{4}+1\right)\left(3 x^{2}+1\right)\left(3 x^{2}-1\right)

lesantik [10]

Step-by-step explanation:

Length = 5 cm and Breadth = 3 cm

Area of a rectangle = length × breadth

=(5×3) cm

2

=15 cm

2

Hence, Area of rectangle with length 5 cm and breadth 3 cm is 15 cm
