A truck is rented at $40 per day plus a charge per mile of use. The truck traveled 15 miles in one day, and the total charge was

$115. Which equation can be used to find the charge x, in dollars, per mile traveled? 40x + 15 = 115 40 + 15x = 115 40x + 15x = 115 40 + 15 = 115x

Answer:

40+15x= 115

Step-by-step explanation:

A truck is rented at $40 per day plus a charge per mile of use. The truck traveled 15 miles in one day, and the total charge was $115.

Let x be the charge per mile of use (dollar per mile)

The truck traveled 15 miles in one day. the charge for 15 miles is 15x

A truck is rented at $40 per day

So charge is 15x+ 40

total charge was 115

So the equation becomes

40+15x= 115

Find the distance between points P(5, 1) and Q(1, 3) to the nearest tenth.
bonufazy [111]

Answer:

Idk if its multiple choice but you can do 1 of 2 ways theres using distance formula =√(5-3)sq+(1-4)sq

=√4+9

=√13 <--

or

3.6 units

Given: The two points that are P(5,1) and Q(3,4).

To find: The distance between these two points.

Solution: It is given that there are two points that are P(5,1) and Q(3,4).

The distance between these two points can be found out as using the distance formula that is: 3.6

Thus, the distance between the given two points is 3.6 units.

So you choose 13 or 3.6 Hope this helps :)

Aroon is asked to choose five integers so that the mode is 2 more than the median and the mean is 2 less than the median.
torisob [31]
  • The mean is the sum of observations divided by number of observations.
  • x bar = (∑x)/n
  • The median is the middle value of the ordered data <u><em>or</em></u> the value of the interval n+1/2 for odd numbered data.
  • The mode is the repeated value.

<h3>The highest value is 0</h3>

  • Number of observations= n= 5
  • Median is the 3rd value when the data is arranged.
  • Mode is unknown

The relation between <u><em>Mean, Median</em></u> and <u><em>mode</em></u> is given by

Mode= 3 Median - 2Mean---- equation1

According to the given condition

Mode= 2+median ----- equation 2

Putting equation 2 in equation 1

2+median= 3 Median - 2Mean

2 Mean= 3 Median - 2- Median

2 Mean= 2 Median - 2

Mean= Median-1

Mean- Median=1--------Eq. A

According to the <u><em>second condition</em></u>

Median- Mode=-2-----------eq. 3

Putting eq. A in eq. 3

Mean -1 - Mode=-2

Mean- Mode=-1

or

Mode- Mean=1------equation 4

Adding <u><em>equation A</em></u> and <u><em>equation4</em></u>

Mode- Mean=1

<u>Mean- Median=1</u>

<u>Mode+ Median =2------- equation5</u>

<u />

Again Putting equation2 in equation 5

2+median + Median =2

2 Median =2-2

2 Median =0

Median=0

Mean= 0-1

Mean= 0-1=-1

Mode- Mean=1

Mode-(-1)=1

Mode=0

Putting values in the formula of mean

x bar =∑x/5

(-1)5 = 0+0+ x1+x2+0

-5=  x1+x2

<u><em>So the highest value is 0.</em></u>
