Answer:
The Chi and Zhang were units of length equivalent to approximately 25 centimeters (9.8 inches) and 3 meters (9.8 feet) respectively.
Step-by-step explanation: 300 centimeters if you need metric measurements.
Answer:
A) 12.5%
B) 50%
C) 50%
Step-by-step explanation:
For A, 7 is one of the 8 possibilities (1/8). 1/8 of 100 is 12.5, so your chance of spinning a 7 is 12.5%
For B, even numbers are 4/8 or 1/2 of your options. 1/2 of 100 is 50, so your chance of spinning an even number is 50%
For C, there are 4 out of 8 numbers that are prime (2,3,5, & 7).
4/8 or 1/2 of 100 is 50, so your chance of spinning a prime number is 50%
hope this helps
A constant is a number that never changes value. Example:
x + 3 = 5, 3 and 5 are constants.
The slope is 0, the equation is y=50
When the line is horizontal the slope is 0 and when the line is vertical the slope is undefined.
A = s^2 and P = 4s.
So if A = 25, then s^2 = 25 so s = 5. Then 4*s = 4*5 = 20
The perimeter of a square with an area of 25cm^2 is 20cm.
Increase the perimeter by 4 to get 24cm. Then 4s = 24 implies s = 6. Then s^2 = A = 6^2 = 36.
Now the area is 36 cm^2
