One circle has a diameter of 6 inches. A larger circle has a diameter that is 4 times the diameter of the circle. what is the ra
harina [27]

Answer:

C, 1 : 16

Step-by-step explanation:

Small Circle

The radius is half of the diameter. 3 inches.

π×r²=A

We'll use 3.14 for pi.

3.14×9

28.26 in²

Bigger Circle

6×4= 24

So the diameter is 24. The radius is 12.

3.14×12²

3.14×144

452.16 in²

Let's divide.

452.16÷ 28.26

= 16

Therefore, the answer is C, 1 : 16.

Hope this helps, please mark brainliest if possible :)

Which represents the polynomial written in standard form? 8x2y2 – StartFraction 3 x cubed y Over 2 EndFraction 4x4 – 7xy3 –7xy3
olga55 [171]

Polynomial equation is a equation which is formed with coefficients variables and exponents with basic mathematics operation and equality sign. The given option the option A matches correctly with the above polynomial equation which is,

-7xy^3+8x^2y^2-\dfrac{3x^3y}{2}+4x^4

Hence the option A is the correct option.

<h3>Given information-</h3>

The given polynomial equation in the problem is,

8x^2y^2-\dfrac{3x^3y}{2}+4x^4-7xy^3

<h3>Polynomial equation </h3>

Polynomial equation is a equation which is formed with coefficients variables and exponents with basic mathematics operation and equality sign.

In the above polynomial equation the variable are<em> x </em>and <em>y </em>and the highest power of the variable <em>x</em> is four and highest power of the variable <em>y</em> is three.

Arrange the polynomial equation in the power of the variable <em>x. </em>Thus,

4x^4-\dfrac{3x^3y}{2}+8x^2y^2-7xy^3

Arrange the polynomial equation in the power of the variable <em>y. </em>Thus,

-7xy^3+8x^2y^2-\dfrac{3x^3y}{2}+4x^4

From the given option the option A matches correctly with the above polynomial equation which is,

-7xy^3+8x^2y^2-\dfrac{3x^3y}{2}+4x^4

Thus the option A is the correct option.

Tanzania [10]

Answer:

c = 160 - 3(45)

Step-by-step explanation:

if c = the number of characters left;

160 = maximum number of characters that can be used in a text

3*45 = number of characters in sentences already used. (There are 3 sentences of 45 characters.)

(# of char left) = (max # char) - (# char already used) so:

c = 160 - 3*(45)

c = 160 - 135

c = 25
