It is 8.96g/cm3. If you multiple 8.96grams by 10 cubic centimeter you will get 89.6g
Answer:
The three given points are the vertices of a right triangle.
Step-by-step explanation:
To determine that the three points are the vertices of a right triangle let us find the distance between each two points
The formula of the distance is
∵ = 6 and = -6
∵ = 9 and = -6
∴ =
∴ = 3
∵ = 6 and = -6
∵ = 9 and = 1
∴ =
∴ =
∵ = 9 and = 1
∵ = 9 and = -6
∴ =
∴ = 7
<em>Let us use the fact that if the square of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle at the vertex which opposite to the longest side</em>
∵ The longest side is
∵ The other two sides are 3 and 7
∵ ( )² = 58
∵ (3)² + (7)² = 9 + 49 = 58
∴ ( )² = (3)² + (7)²
- By using the fact above
∴ The triangle is a right triangle
The three given points are the vertices of a right triangle.
Declan has 9 dimes and 8 quarters in his pocket.
<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the number of dimes and y represent the number of quarters.
A dime is worth 10 cents. A quarter is worth 25 cents.
Hence:
x + y = 17 (1)
Also:
10x + 25y = 290 (2)
From equation 1 and 2:
x = 9, y = 8
Declan has 9 dimes and 8 quarters in his pocket.
