Answer:

7.74 cm^2

Step-by-step explanation:

The length of the side of the square is 3+3 = 6

The area of the square is

A =s^2 = 6^2 = 36

The area of the circle is

A = pi r^2 where the radius is 3

(3.14) 3^2 =28.26

Subtract the area of the circle from the area of the square to get the shaded area

36-28.26 = 7.74 cm^2

Colin and Brian were playing darts. Colin scored 91. Brian scored 9 more than Colin. What was their combined score?

Sloan [31]

Answer:
The combined score was 191

Simplify. 2u? - 20u +42 u² – 5u+6

chubhunter [2.5K]

Answer:

The simplified expression is:

$\frac{2(u + 7)}{(u- 2)}$

Step-by-step explanation:

We want to simplify:

$\frac{2 {u}^{2} - 20u + 42}{ {u}^{2} - 5u + 6}$

We factor the numerator and the denominator to get:

$\frac{2(u - 3)(u + 7)}{(u- 2)(u- 3)}$

Cancel out u-2 which is common to the numerator and the denominator yo get:

$\frac{2(u + 7)}{(u- 2)}$

In step one do you found the volume (in cubic feet) of the main tank(359,006.67). The maximum density of killer whales per cubic

Luba_88 [7]

Answer:

4 killer whales

Step-by-step explanation:

The dimensional analysis is ...

(whales/ft³)(ft³/tank) = whales/tank

Putting the numbers with the units, we get ...

(1.1142·10^-5 whales/ft³)(3.5900667·10^5 ft³/tank) = 4.00005... whales/tank

The maximum number of killer whales allowed in the main show tank is 4.
