Tiana can clear a football field of debris in 3 hours. Jacob can clear the same field in 2 hours. If they decide to clear the fi
Lapatulllka [165]
Let us determine each of their rates of work:

Since Tiana can clear the field in 3 hours, meaning she can do 1/3 of the work per hour.

In the same way, Jacob can do 1/2 of the work per hour. 

Now, what would be the rate of work if they were working together? Let's look at it like this:

Hours to complete the job:
Tiana = 3
Jacob = 2
Together = t

Work done per hour:
Tiana = 1/3
Jacob = 1/2
Together = 1/t

If you add their labor together:

1/3 + 1/2 = 1/t
5/6 = 1/t
t = 6/2 = 1.2

Together, they can clear the field in 1.2 hours.

Total 427 tickets sold 73 fewer student tickets than adult tickets how many adult tickets
viktelen [127]

9514 1404 393

Answer:

  250

Step-by-step explanation:

Let 'a' represent the number of adult tickets.

  a +(a -73) = 427

  2a = 500 . . . . . add 73

  a = 250 . . . . . . divide by 2

250 adult tickets were sold.

_____

<em>Additional comment</em>

I call this a "sum and difference problem" because we are given the total of two values and the difference between them. As you can see here, the larger of the two values is the average of the given numbers, their sum divided by 2. This is the generic solution to such a problem: the larger number is the average of the given sum and difference.

What is 2-(-8)????? And how do you solve it????
marusya05 [52]
<h3>Answer: 10</h3>

Subtracting a negative is the same as adding a positive. So 2-(-8) is really 2+8 = 10.

With something like 2-8, we start at 2 and move to the left 8 units to arrive at -6 on the number line. When we do 2-(-8), we start at 2 and move 8 units in the opposite direction since -8 is the opposite of 8.

In terms of money, you can think of a negative number as an IOU or it represents the amount of debt. Writing -8 means you are 8 dollars in debt. If we subtract away debt, then we have less of it and effectively its the same as adding dollars to your pocket. Subtracting away 8 dollars of debt is the same as adding 8 dollars to your pocket, which is one interpretation of how 2-(-8) is the same as 2+8.

Straight-Line Depreciation A small delivery truck was purchased on January 1 at a cost of $21,920. It has an estimated useful li
lesantik [10]

Answer:

Rate of depreciation per year  is 4310 $/ year and the depreciation schedule is given below.

Step-by-step explanation:

According to the question,

since, it is straight-line depreciation,

rate of depreciation per year = \frac{21920 - 4680}{4}   $/year

                                                = 4310 $/ year

So we can prepare the following table.  (year = 0 for the base period)

Year    Depreciation   Accumulated      Book value

              expense        depreciation  

                 ( in $)               (in $)                    (in $)

 0              0                         0                      21920

 2           4310                     8620                  13300

For which segment lengths is QS¯¯¯¯¯ parallel to MN¯¯¯¯¯¯¯ ? A triangle with vertices labeled as Q, R, S. Side Q S is base. Side
Andrew [12]

Answer:

Thus, (1) is non parallel set and (2) and (3) are parallel set.

Step-by-step explanation:

Consider a triangle with vertices labeled as Q, R, S. Side QS is base. Sides RQ and RS contain midpoints M and N, respectively. A line segment is drawn from M to N as shown in figure below.  

For MN and QS to be parallel the ratio of line segment must be in same ratio, that is \frac{RM}{RQ}=\frac{RN}{RS}.

Check for the given options,

1) Given : QM=2, MR=4, SN=3, NR=5

Find the values in the ratio,

\frac{RM}{RQ}=\frac{RM}{RM+MQ}=\frac{4}{6}=\frac{2}{3}

\frac{RN}{RS}=\frac{RN}{RN+NS}=\frac{5}{8}=\frac{5}{8}

Thus, \frac{RM}{RQ}\neq \frac{RN}{RS}

Thus, (1) is non parallel set.

2) Given : QM=2, MR=5, SN=6, NR=15  

Find the values in the ratio,

\frac{RM}{RQ}=\frac{RM}{RM+MQ}=\frac{5}{7}

\frac{RN}{RS}=\frac{RN}{RN+NS}=\frac{15}{21}=\frac{5}{7}

Thus, \frac{RM}{RQ}=\frac{RN}{RS}

Thus, (2) is parallel set.

3) Given: QM=2, MR=8, SN=3, NR=12

Find the values in the ratio,

\frac{RM}{RQ}=\frac{RM}{RM+MQ}=\frac{8}{10}=\frac{4}{5}

\frac{RN}{RS}=\frac{RN}{RN+NS}=\frac{12}{15}=\frac{4}{5}

Thus, \frac{RM}{RQ}=\frac{RN}{RS}

Thus, (3) is parallel set.
