Answer:
157 square yards.
Step-by-step explanation:
Given:
Width of walk around a circular swimming pool = 2 yard
The diameter of the pool = 23 yard
Question asked:
What is the area of the walk ?
Solution:
<em>To find area of walk, we will first calculate area of the pool and then combined area of pool and walk then after we will subtract the area of pool from combined area.</em>
The diameter of the pool = 23 yard
Radius of the pool = 
<u>As width of walk around a circular swimming pool is 2 yard :</u>
New radius will be = 11.5 + 2 = 13.5 yard
Now, area of the walk = Combined area of pool and walk - Area of the pool
= 572.265 - 415.265
= 157 square yards
Therefore, area of the walk is 157 square yards.
Answer:
1:0.06
Step-by-step explanation:
since there is a 6% sales tax, which is the same as 0.06. to calculate your tax, you would multiply both of the sides of the ratio by 75, and the left side will show you subtotal of what you are buying, the right will show tax.
Answer is x=-4 second choice
The measure of angle A in the triangle is 18°
<h3>How to determine the measure of angle A?</h3>
The angles in the triangle are given as:
m∠A = (2x − 24)°, m∠B = (x + 8)°, m∠C = (4x + 49)°
The sum of angles in a triangle is 180
So, we have
m∠A + m∠B + m∠C = 180
Substitute the known values in the above equation
So, we have:
2x − 24 + x + 8 + 4x + 49 = 180
Evaluate the like terms
7x = 147
Divide both sides by 7
x = 21
Substitute x = 21 in m∠A = (2x − 24)°
m∠A = (2 * 21 − 24)°
Evaluate
m∠A = 18°
Hence, the measure of angle A in the triangle is 18°

Answer:
Option A) y=1000(1.15)^6 2313 bacteria
Step-by-step explanation:
The initial value is 1,000 and the growth factor would be the the 15%.
15% can be rewritten to .15, but you have to have to add 1 for the start to make the equation easier. Thus making the growth factor 1.15
After multiplying 1000(1.15)^6 you will get 2313.06076562 which is simplified to 2,313 bacteria.
Hope this is helpful. :)
