1. The diameter of one side of a 10-foot log is approximately 13 inches. The diameter of the other side of the log is approximat

To best estimate the volume of the log, we assume that the diameter is the average of the diameters at both ends giving us 12 inches as the diameter. Thus, the radius is equal to 0.5 ft. The volume of the log is calculated through the equation,
                      V = πr²h = π(0.5 ft)²(10 ft) = 7.85 ft³

I don't understand this at all. can someone explain?
ElenaW [278]

Answer:

In order, your numbers are

22, 45, 75, 89, 89, 95, 100

The median is the number that is in the middle numbers of all your numbers. The median is 89, since it is in the very middle.

The mean is all your numbers added together and then divided by how ever many numbers you have. 22 + 45 + 75 + 89 + 89 + 95 + 100 = 515. Since you have 7 numbers, you would divide 515 by 7, which equals 73.5. The mean is 73.5.

The mode is the number that has the most numbers(not sure how to word it) Since 89 has two of the numbers, and no other numbers have duplicates, your mode is 89.

I need to drink 8 2/4 cups of water and 2 1/5 cups milk every day. How much fluid do I have to drink?
lidiya [134]

Answer:

The total fluid you have to drink is 10  7/10  =  10.7  cups.

Step-by-step explanation:

The daily requirement  of water =  8 2/4 cups

Now, 8 \frac{2}{4}  = 8+  \frac{2}{4}  = 8+ 0.5 = 8.5

or, the daily water requirement = 8.5 cups

The daily requirement  of milk =  2 1/5 cups

Now, 2 \frac{1}{5}  = 2+  \frac{1}{5}  = 2+ 0.2 = 2.2

or, the daily milk requirement = 2.2 cups

So, The total fluid needed  = Cups of  (Water + Milk) needed

                                              =  8.5 cups + 2.2 cups

                                              = 10.7 cups

Also, 10.7 = 10 + 0.7 = 10 + \frac{7}{10}  = 10\frac{7}{10}

Hence, the total fluid you have to drink is 10 7/10 cups.

Which is the equation of Line B?
notka56 [123]
  • Slope-Intercept Form: y = mx + b, with m = slope and b = y-intercept
  • Slope Formula: \frac{y_2-y_1}{x_2-x_1}

So firstly, to find the slope of this equation, plug the two points, (1,1) and (-3,2), into the slope formula and solve as such:

\frac{1-2}{1-(-3)}=-\frac{1}{4}

Next, plug either one of the points into the x and y coordinates to solve for b as such:

2=-\frac{1}{4}*-3+b\\2=\frac{3}{4}+b\\\frac{5}{4}=b

<u>Our final equation is y=-\frac{1}{4}x+\frac{5}{4} , or the third option.</u>
