1 apple weighs 150 grams.
To find how much 9 apples weight, multiply the unit weight of the apples by 9.
150 • 9 = 1350
9 apples weight 1,350 grams.

There are 1,000 grams in a kilogram.
1 gram = 0.001 kilogram.
1350 grams = 1.35 kilograms

If Li needs 2 kilograms of apples, then 9 apples are not enough because 1.35 kilograms is less than 2 kilograms.

State whether the equation is true, false or open? 4y+8=6y+3
g100num [7]

<u><em>Answer:</em></u>

Open


<u><em>Explanation:</em></u>

An open equation is an equation that has variables and CAN be solved

<u>Example</u>: 2x = 4 ......> can be solved giving ......> x = 2

A false equation is one where both sides can NEVER be equal

<u>Example:</u> 15 = 2(3) + 1 ..........> 15 can never be equal to 7

A true equation is one having no variables and both sides are ALWAYS equal

<u>Example:</u> 2(3) + 1 = 2(2) + 3 ........> 7 will always be equal to 7


Now, the given equation is:

4y + 8 = 6y + 3

Let's try to solve is:

4y + 8 = 6y + 3

6y - 4y = 8 - 3

2y = 5

y = 2.5


Therefore, the given equation contains a variable and can be solved which means that it is an open equation


Hope this helps :)

What is the exact volume of a cone whose base radius is 9 feet and whose height is 13 feet? Show your work.
Radda [10]

Answer:

<u>The volume of the cone is 1,102.7 feet³ (cubic)</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Radius = 9 feet

Height = 13 feet

2. What is the exact volume of the cone?

We will use the following formula to calculate the volume of the cone:

Volume of the cone = π * Radius² * Height/3

Volume of the cone = 3.1416 * 9² * 13/3

Volume of the cone = 3.1416 * 81 * 13/3

Volume of the cone = 3.1416 *9² * 13/3

<u>Volume of the cone = 1,102.7 feet³ (cubic)</u>
