Answers:
x = 13
Question mark angle is 64 degrees
============================================================
Explanation:
Let y be the angle labeled as a question mark.
This angle y is adjacent to the exterior angle of measure 116 degrees
This means y and 116 must add to 180 to form a straight angle
y+116 = 180
y = 180-116
y = 64
So 64 degrees will replace the question mark.
Then we can find the angle x. Recall that all angles of a triangle add to 180
90+2x+y = 180
90+2x+64 = 180
2x+154 = 180
2x = 180-154
2x = 26
x = 26/2
x = 13
-----------------
Alternatively, you can find x through the remote interior angle theorem
The interior angles 90 and 2x add to the exterior angle 116
90+2x = 116
2x = 116-90
2x = 26
x = 26/2
x = 13
This method doesn't involve angle y.
A cup contains 8 fluid ounces. Therefore, 8 cups would have 64 fluid ounces. Divinding 64 by 20 fluid ounces would equal to 3.2. So, Lexie would need to drink 3.2 water bottles to meet her goal of drinking 8 cups of water.
A.) 120
The variance is the range of a data set, which shows how spread out numbers are. To get the variance, we take the last number and subtract it from the first number. 160-40=120. Therefore, there is 120 numbers between 40 to 160.
Answer:
C. 40 cm
Step-by-step explanation:
length of side of square = s
perimeter = s + s + s + s = 4s
We use the formula P = 4s
P = 4 * 10 cm
P = 40 cm
Answer: The perimeter is 40 cm.
Notice that the perimeter is a sum of lengths, so its units are linear units such as cm, inches, feet, a unit of length.
An area has square units such as cm^2, in.^2, ft^2, etc.
Y = f(x)
The initial value will be the first point. (0,3)
3 = initial value of function, f(0)
