Answer:
5 miles
Step-by-step explanation:
It may get a bit messy, but we can solve for the desired value directly. Let d = the distance walked (in miles). Then 20-d is the distance traveled in the car. The relevant relation is ...
time = distance / speed
The total travel time is 9:00 -6:50 = 2:10 = 2 1/6 hours = 13/6 hours. Here is the equation for total travel time.
total time = time spent walking + time spent riding
13/6 = (d/3) + (20-d)/30
Multiplying by 30 gives ...
65 = 10d + 20 -d
45 = 9d . . . . . . . . . . subtract 20
5 = d . . . . . . . . . . . . divide by 9
The girl walked 5 miles.
_____
<em>Check</em>
Her walking time was (5 mi)/(3 mph) = 5/3 h = 1:40.
Her riding time was (15 mi)/(30 mph) = 1/2 h = 0:30.
Her total travel time was 1:40 +0:30 = 1:70 = 2:10, as required.
The line is solid so we have either ≤ or ≥
find the equation of the line
ok, a y intercept if -1
sllope=rise/run=3/1=3
y=mx+b
m=slope
b=y intercept
y=3x-1 is the equaton
now find if it's y≥3x-1 or y≤3x-1
test a point
we see (0,0) Is not in in it
test it in y≥3x-1
0≥3(0)-1
0≥-1
false,
so this is the equation because (0,0) is not a valid solution for this equation
answer is y≥3x-1
Answer:
Step-by-step explanation:
- R = F/(N + F)
- R (N+F) = F
- RN + RF = F
- F - RF = RN
- F(1 - R) = RN
- F = RN/(1 - R)
Correct option is B)
Answer:
The correct option is B.
Step-by-step explanation:
Consider the diagram below.
It is a Venn diagram.
The diagram shows that all the natural numbers are contained in the set of all the whole numbers.
This implies that all natural numbers are whole numbers.
Then the statement best describing the relationship between whole numbers and natural numbers is:
(B) The diagram shows that natural numbers are a subset of whole numbers, because all natural numbers are whole numbers.
Thus, the correct option is B.
