Answer:
$102.14
Step-by-step explanation:
2.8 hours a day X 4 days = 11.2
11.2 X $9.12 = 102.144
rounded to the nearest cent is $102.14
45 minutes?
Answer:
13/2
Step-by-step explanation:
Keep in mind that speed*time=distance
ok so, if you convert 8 2/3 in to a improper fraction you'll get 26/3. Now we have to turn 45 minutes into a fraction so it's easier to multiply, that would be 45/60 because 1 hour has 60 minutes. Now, we would multiply 26/3 and 45/60 and get 78/12. Simplify that and get 13/2
Answer:390 miles
Step-by-step explanation:
speed*time=distance (keep that in mind)
8 2/3 is also equal to 26/3
take that number and multiply that by 45 min
45*26/3
that equall 390 miles
(I tried my best, I might be wrong)
For this case, the first thing we must do is define variables.
We have then:
y: number of caps
x: number of shirts
We now write the system of equations that represents the problem:
The graphical solution of the system of equations (see attached image) is:
Therefore, we have 4 shirts and 4 caps.
Answer:
See attached image for the graphic
number of caps = 4
number of shirts = 4
