Answer:
Interest rate is 5.25% a year.
Step-by-step explanation:
r = (1/54)((22252.5/18000) - 1) = 0.004375
r = 0.004375
Convert decimal to percentage
R = 0.004375 * 100 = 0.4375%/month
Calculate annual rate
0.4375%/month × 12 months/year = 5.25% per year.
35,569.92 L of water is required to fill the pool
Step-by-step explanation:
- Step 1: Find the area of the circular pool when radius = 20/2 = 10 ft
⇒ Area = πr² = 3.14 × 10² = 314 ft²
- Step 2: Find the volume of the pool
Volume = Area × Depth
= 314 × 4 = 1256 ft³
- Step 3: Convert the volume into liters.
Volume of water = 1256 × 28.32 = 35,569.92 L (∵1 ft³ = 28.32 L)
Answer:
9*(6+7)
Step-by-step explanation:
First, we have to find the Greatest Common Factor (GCF), to do this we have to see all the factors of 54 and 63 and find the greatest factor that they have in common.
Factors of 54
1,2,3,6,9,18,27,54
Factors of 63
1,3,7,9,21,63
The GCF is 9 because is the greatest factor that is common to both numbers.
Now we have to divide 54/9 and 63/9
54/9 = 6
63/9 = 7
So now we can write the product of the GCF and another sum:
9*(6+7)
<em>We can prove this by solving both expressions:</em>
<em>54+63 = 9*(6+7)</em>
<em>117 = 9*13</em>
<em>117 = 117 </em>
<em>The results are equal so we prove it is right.</em>
