Answer:

18.8 inches

Step-by-step explanation:

The circumference is \displaystyle{C = 2\pi r}. The diameter is two times of radius which can be expressed as \displaystyle{d = 2r}.

We can rewrite the equation of circumference as \displaystyle{C = \pi d}<em>. </em>Thus, substitute d = 6 in:

\displaystyle{C = 6\pi}\\\\\displaystyle{C = 18.849}

Rounding to the nearest tenth, we will get:

\displaystyle{C = 18.8 \ \sf \ inches}

Hence, the circumference is 18.8 inches.

A function is expressed by the equation y=0.3x−6. For what value of the independent variable will the value of the function be e
Anna11 [10]

Answer:

0; 10; 20

Step-by-step explanation:

x is the independent variable

y is the dependent variable

y is dependent on x

a) For what value of the independent variable will the value of the function be equal to −6

y=0.3x−6

-6 = 0.3x-6

0=0.3x

x = 0

Therefore, if the independent variable is 0, the value of the function will be -6.

b) For what value of the independent variable will the value of the function be equal to −3

y=0.3x−6

-3 = 0.3x-6

0.3x = -3+6

0.3x = 3

x = 3/0.3

x = 10

Therefore, if the independent variable is 10, the value of the function will be -3.

c) For what value of the independent variable will the value of the function be equal to 0.

y=0.3x−6

0=0.3x-6

6 = 0.3x

x = 6/0.3

x = 20

Therefore, if the independent variable is 20, the value of the function will be 0.

1 question. A big square is made up of 4 identical small squares the area of each small square is 25 cm A. Find the length of ea
Bogdan [553]

Answer:

50cm

200cm

50cm^2

Step-by-step explanation:

The big square is divided into 4 with a side length of 25cm. 2 small square side lengths make up the big squares.

25 * 2 =

50cm

50 + 50 + 50 +50 =

200

15 +2

17

8 + 2

10

17 * 10 = 170

15 * 8 = 120

170-120 = 50

50cm^2
