10000 cm cubed
Step-by-step explanation:
The surface area of the present is 25 times 20 times 20 which equals 10000 cm cubed.
Answer:
The actual park has 0.7776 square meters
Step-by-step explanation:
To solve this we first have to find the value of the scale
We know that the width of the model is 8cm and that of the true park is 72cm², so if we divide 72 by 8 we will obtain the value of the scale
72 / 8 = 9
To find out how much the park area has, the park first we have to multiply 96cm² by the scale
As the scale of 9 is made for width and length, when we calculate the area it will be multiplied 2 times by 9, so to calculate the real area we have to multiply it 2 times
96cm² * 9 * 9 = 7776cm²
if we want the result in square meters we simply have to divide the result by 100²
7776cm²/100² = 7776cm² / 10,000
0.7776m²
The actual park has 0.7776 square meters
Answer:
A linear equation can have no, one or infinite solutions.
Step-by-step explanation:
No Solution:
Consider the equation 8x - 19 = 8x + 19
Subtract 8x from both the sides. We get:
8x - 8x - 19 = 8x - 8x + 19
⇒ - 19 = 19
This is absurd. So, this system of equations has no solution.
One Solution:
For the equation 9x + 5 = 14
⇒ 9x = 9
⇒ x = 1 the only solution to the equation.
Infinite Solutions:
The solution to the equation 3x = 3x are infinite.
Whatever the value of x the equation always remains the same. So, we have infinite values of x that can satisfy the equation.
