Same with the other question we did, we are given the area of each tile which is 4 1/2in^2.
All we need to do it divide.
252 / 4.5 = 56
So, she would need 56 tiles in total.
Best of Luck!

Write N as a product of powers of its prime factors.
N = 5^(10) × 2^(14) × 3
This is about prime factors
By definition, a prime factor is a factor of a number and that factor is also a prime number.
A prime number is one that is divisible by only itself and 1.
The number we have is; 480 × 10^(9)
Now, let's list the prime factors or 480 and they are;
2, 3, 5
Now, using these prime factors alone to get 480, we have;
5 × 3 × 2 × 2 × 2 × 2 × 2 = 480
In powers, gives;
5 × 3 × 2^(5)
Now,the 10^(9) with the 480 can also be expressed in terms of it's prime factors which are 2 and 5 as;
(5 × 2)^(9)
Expanding this gives; 5^(9) × 2^(9) = 10^(9)
Thus;
480 × 10^(9) = 5 × 3 × 2^(5) × 5^(9) × 2^(9)
This gives;
5^(10) × 2^(14) × 3

Answer:
I got 5^10 x 2^14 x 3
Step-by-step explanation:
1. Do a tree to find 480 as a product of its prime factors
2. You should get 480= 5x2x3x2x2x2x2
3. 10 expressed as a product of its prime factors is 5x2
4. so 10^9 expressed as a product of its prime factors would be
5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2
5. You can then write out 480x10^9 as a product of its prime factors
5x2x3x2x2x2x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2
6. change this to use powers
5^10 x 2^14 x 3
The number of games in which Fairlawn High scored between 15 and 36 points is 22.
To determine the number of games in which Fairlawn High scored between 15 and 36 points, we need to find the range of scores. If the range is inclusive of both endpoints, we subtract the lower score from the higher score and add 1. So the number of games is 36 - 15 + 1 = 22.

Answer:
The first reactant takes approximately 147 seconds to reach half its initial concentration, while the second reactant takes approximately 214.5 seconds for the same reduction, based on their half-lives and initial concentrations.
Step-by-step explanation:
The rate constant (k) for a first-order reaction can be calculated using the formula:
k = (0.693) / t_half
For the first set of data:
k₁ = (0.693) / 147 s ≈ 0.00472 s⁻¹
For the second set of data:
k₂ = (0.693) / 215 s ≈ 0.00322 s⁻¹
Now, you can use these rate constants to calculate the time it takes for each reactant to reach a certain concentration. For example, if you want to find the time it takes for the first reactant (initial concentration = 0.294 M) to reduce to 0.147 M (half its initial concentration), you can use the following equation for a first-order reaction:
ln(C_t / C₀) = -kt
Where:
C_t = concentration at time t
C₀ = initial concentration
k = rate constant
t = time
For the first reactant:
ln(0.147 / 0.294) = -0.00472t
Solving for t:
t ≈ 147 seconds
For the second reactant (initial concentration = 0.201 M) to reduce to 0.1005 M (half its initial concentration):
ln(0.1005 / 0.201) = -0.00322t
Solving for t:
t ≈ 214.5 seconds
So, it takes approximately 147 seconds for the first reactant to reach half its initial concentration, and approximately 214.5 seconds for the second reactant to do the same, based on their respective half-lives and initial concentrations.
