Answer:
41.22
Step-by-step explanation:
12+28 = 40
0.54 + 0.68 = 1.22
40 + 1.22 = 41.22
Answer:
A
Step-by-step explanation:
h determines how much d she will get and hence B and D are wrong
independent variable means the cause
dependent variable means the effect
Answer:
0.05
Step-by-step explanation:
The formula for slope is rise/run.
So, in this case it would be 2.9ft/58ft = 0.05
The mode of the given data set is 42, becuase mode is define as the number with the must number of responses or result.
The mean of the given data set is 26.89, because it is define as the average of the data set
The median of the data set is 42, it is define as the middle figure when the data set is already arrange ascending or descending.
Answer:
(21x+168)cm²
Step-by-step explanation:
If the expression 2 1 (x + 8) represents the area of the model bridge, where 2 1 is the width, in centimeters, and (x + 8) represents the extended length, the expression that is equivalent to 21(x+8) can be gotten by expanding the function. The expansion of the function will give the area of the rectangular model bridge as shown;
21(x+8) = 21x+ 168
The expression equivalent to 21(x+8) is therefore (21x+68)cm²
Note that the the unit of the value and function given is in cm therefore the unit of their equivalent expression will be in cm²
