Answer: 7/20
Step-by-step explanation:
3/4 - 2/5
= 3x5/4x5 - 2x4/5x4
=15/20 - 8/20
= 7/20
Hope it helped u,
pls mark as the brainliest
^_^
Answer:
First, you will need to arrange the data in an ascending order and the median is the middle value.
If the number of values is an even number, the median will be the average of the two middle numbers.
2, 6, 7, 10, 11, 15, 15
The median in this set is <em><u>10</u></em>.

Answer:
The radius is 9.0 units
Step-by-step explanation:
we know that
In the right triangle of the figure ABC
Applying the Pythagorean Theorem
![AC^2=AB^2+BC^2](https://tex.z-dn.net/?f=AC%5E2%3DAB%5E2%2BBC%5E2)
substitute the given values
![15^2=AB^2+12^2](https://tex.z-dn.net/?f=15%5E2%3DAB%5E2%2B12%5E2)
solve for AB
![AB^2=15^2-12^2\\AB^2=81\\AB=9\ units](https://tex.z-dn.net/?f=AB%5E2%3D15%5E2-12%5E2%5C%5CAB%5E2%3D81%5C%5CAB%3D9%5C%20units)
Remember the the side AB of right triangle represent the radius of the circle
therefore
The radius is 9.0 units
Answer:
- 8 3/4
- 2, 3
- 4 1/2, 11 1/4
- 9 3/4, 16 1/4
- Y/B = 2/3
Step-by-step explanation:
<h3>a)</h3>
The first line is simply the sum of the two given numbers.
3 1/2 +5 1/4 = (3+5) +(2/4+1/4) = 8 3/4
__
To find values on the remaining lines, it is convenient to find the ratios of the numbers involved. The ratio of yellow to blue is ...
Y/B = (3 1/2)/(5 1/4) = (7/2)/(21/4) = (7/2)(4/21) = 2/3
Then ...
Y : B : total = 2 : 3 : 5
This tells you the numbers on the second line are ...
Y = 2; B = 3
__
The value for B on the third line is the basic ratio number multiplied by (6 3/4)/3 = 2 1/4. Then the other two numbers are ...
Y = 2(2 1/4) = 4 1/2
total = 5(2 1/4) = 11 1/4
__
The value for Y on the fourth line is the basic ratio number multiplied by (6 1/2)/2 = 3 1/4. Then the other two numbers are ...
B = 3(3 1/4) = 9 3/4
total = 5(3 1/4) = 16 1/4
_____
<h3>b)</h3>
The equation is the one we used to find the values on the second line:
Y/B = 2/3
Answer:
i believe the answer is A
