It'd be A since dividing on a negative coefficient results flipping the sign of the inequality and results in a different impact
Answer:
7.065
Step-by-step explanation:
There are two ways to do this:
(Note: area = pi * r^2)
Method 1:
Diameter of A = 4, so radius = 4/2 = 2
Area of A = 3.14 * 2^2 = 12.56
Diameter of B = 5, so radius = 5/2 = 2.5
Area of B = 3.14 * 2.5^2 = 19.625
Difference in area = 19.625 - 12.56 = 7.065
Method 2:
First find out how much larger the diameter of B is than A, so 5/4 = 1.25.
What this means is if you take the diameter of A and multiply it by 1.25, you get the diameter of B.
When dealing with area, the area of B will be 1.25^2 times bigger than A.
Area of A = 3.14 * 2^2 = 12.56
So area B = 12.56 * 1.25^2 = 19.625
Difference = 19.625 - 12.56 = 7.065
Answer:
Step-by-step explanation:
<h3>Given</h3>
<u>The equation for simple interest:</u>
<u>And values</u>
<h3>Solution</h3>
<u>Interest amount is</u>
<u>Solving for annual interest rate</u>
- 160 = 2000*2r
- 160 = 4000r
- r = 160/4000
- r = 0.04
- 0.04*100% = 4%
Annual interest rate is 4%
Answer:
The answer is -19
Step-by-step explanation:
-27 - (-8)=
-27+8
=-19
You have a lot of different questions here, I can help with the first part.
The range is the highest minus the lowest.
26 - 10 = 16
The mean is the result when you add them all up and divide by 10.
170 / 10 = 17
The median is the middle number in order.
The middle is at 15.
The mode is the number that shows up the most.
14 appears twice, every other number appears only once.
