Answer:

30 miles.

Step-by-step explanation:

A van will drive 10 miles north, 15 miles south, and then 5 miles north again.

Van will drive total distance = 10 + 15 + 5  = 30 miles.

Relative distance is 0 miles since the van is back where it started.

The total distance to travel is 30 miles and van gets 33 miles per gallon. There is one gallon of gas left in the tank so there is enough fuel for the trip.

25.What is the average rate of change for the sequence shown?
d1i1m1o1n [39]

Given the following points:

(1, 4): (2, 2.5): (3, 1) and (4, -0.5).

We are asked to find the average rate of change of the sequence.

The average rate of change for the sequence is the slope and it can be solved using the slope formula.

Slope (m) = y2 - y1

x2 - x1

So, lets choose two points on the line and substitute into the formular.

(1, 4) and (2, 2.5)

where:

x1 = 1

x2 = 2

y1 = 4

y2 = 2.5

m = 2.5 - 4

2 - 1

m = -1.5/1

m = -1.5

m = -1 1/2

Therefore, the correct option is the second option.

Angharad had an operation costing $500 She was in hospital for x days The cost of nursing care was $170 for each day she was in
Ket [755]

Answer:

a) Total cost = 500 + 170x

b) 11 days

Step-by-step explanation:

Given:

(a)

Number of days in hospital = x

Cost of operation = $ 500

Cost of nursing per day = $170

∴ Cost of nursing for x days = $ 170x

Therefore, the expression for total cost of her operation and nursing care is given as,

C=500+170x, where C is the total cost.

(b)

Given:

Total cost of operation = C=\$ 2370

Using the expression obtained in (a), we solve for x.

C=500+170x

Plug in 2370 for C and solve for x. This gives,

2370=500+170x\\ 170x=2370-500\\ x=\frac{1870}{170}\\x=11

Therefore, Angharad stayed in hospital for 11 days.

Find the m&lt;3 if m&lt;5=130 and m &lt;4=70 equal
olga nikolaevna [1]

<2 + <5 = 180  this is a straight line

<2 + 150= 180

subtract 150 from each side

<2 = 30

<2 + <3 + <4 = 180  a triangle is 180 degrees

30 + <3 + 70 = 180

100 + <3 = 180

<3 = 80
