Answer:
The density of the pine log is 0.2842 pounds per inch.
Step-by-step explanation:
To calculate the density of an object, you must divide its mass by its volume (radius times height). Thus, given that the pine log that has a 5-inch radius and is 30 inches long, while its weight is approximately 42.63 pounds, the following calculation must be performed to determine its density:
X = 42.63 / (30 x 5)
X = 42.63 / 150
X = 0.2842
Thus, the density of the pine log is 0.2842 pounds per inch.
The x intercept is when the line passes through the x axis , the only time that happens is when y=0
the y intercept is when the line passes through the y axis, the only time that happens is when x=0
so to solve for them, set the other coortinate to zero so
x intercept is when y=0 so set y to zero and solve for x
0-1/4x=-1/2
-1/4x=-1/2
multiply both sides by -4/1
x=2
the x intercept is (2,0)
the y intercept is when x=0 so set x to zero
y-1/4(0)=-1/2
y=-1/2
the y intercept is (0,-1/2)
the x itnercept=(2,0)
the y intercept=(0,-1/2)
Answer:
22 per dog when she is walking 8
she would make 176 for walking all 8 of them
Step-by-step explanation:
For each additional dog she walks she is giving a discount. If you subtract each one you will see she is giving a 2.75 discount.
40-37.25 = 2.75
37.25-34.50 = 2.75
34.50-31.75 = 2.75
Since you know she gives a discount of 2.75 per dog you can take that times the number of dogs (8).
8 x 2.75 = 22 per dog
Then take that amount and multiply it by the number of dogs she is walking.
8 x 22 = 176 for all 8 dogs
If I'm right, then the answer would be B. 800. Hope I helped!
