Answer:

952 cubic feet

Step-by-step explanation:

The diameter is 21, so the radius is 10.5. The area of a circle is πr^2, so 10.5^2π, or 110.25π. The pool is filled 9 inches from the top, so it is 3.5 feet - 9 inches high, 9 inches is 0.75 feet, so 2.75 feet filled. Now multiply 110.25π by 2.75 to get 303.1875π and then 952.4916, closer to 952 cubic feet.

The aquarium has a scale model of a great white shark for sale in their gift shop. If the scale of the model is 2 in. : 7 ft, wh
kompoz [17]

Answer:

14ft

Step-by-step explanation:

Since the scale is 2in : 7ft, so you would do 7x2 which gets you to 14.

(You would do 7x2 because 4 in/2 in = 2in, that's where the 2 comes from, and 7 because 7ft is part of the scale.)

Hope this helps :D

Found out g<br> 2(g - 15) = -26 <br> Please help
posledela

Answer: g=2

Step-by-step explanation:

To solve this exercise you need to remember the following properties:

1. The Distributive property states that:

a(b+c)=ab+ac\\\\a(b-c)=ab-ac

2. The Addition property of Equality statest that:

If a=b, then a+c=b+c

3. The Subtraction property of Equality statest that:

If a=b, then a-c=b-c

4. The Division property of Equality statest that:

If a=b, then \frac{a}{c}=\frac{b}{c}

5. The Multiplication property of Equality statest that:

If a=b, then a*c=b*c

Given the equation:

2(g - 15) = -26

You must solve for "g" in order to find its value:

- Apply the Distributive property:

2g - 30= -26

- Apply the Addition property of Equality adding 30 to both sides of the equation:

2g - 30+30= -26+30\\\\2g=4

- Apply the  Division property of Equality dividing both sides by 2:

\frac{2g}{2}=\frac{4}{2}\\\\g=2
