Answer:
2 hours
Step-by-step explanation:
Circumference = pi × d
126 = 3.14 × d
d = 40.127388535 yards
d = 40 yards (nearest whole number)
Time = 40/20 = 2 hours
The answer of Cubic root of 343 is 7
Answer:
Proportional: Mike, a plumber charges $5 per hour for his service.
Non-proportional: Mike charges a initial cost of $10 plus $3 for each hours of service.
Step-by-step explanation:
Let us assume that Mike, a plumber charges $5 per hour for his service.
So, the number of hours (h) of service and the total charge (C) are proportional, which is
C(h) = 5h ....... (1)
If the condition changes like, Mike charges an initial cost of $10 plus $3 for each hour of service.
Here, the equation that models the situation is
C(h) = 10 + 3h .......... (2)
Now, relation (1) is non-proportional. (Answer)
Answer:
-1 3/4 =x
Step-by-step explanation:
-3 1/2= 1/2x+1/2x+x
Combine like terms
-3 1/2 = 2x
Change to an improper fraction
- ( 2*3+1)/2 = 2x
-7/2 = 2x
Multiply each side by 1/2
-7/2 *1/2 = 2x* 1/2
-7/4 = x
Changing to a mixed number
-4/4 -3/4 =x
-1 3/4 =x
Consecutive odd integers means that the equation is
(x)+(x+2)+(x+4)+(x+6)+(x+8)=-65
add like terms
5x+20=-65
subtract 20 from both sides
5x=-85
divide both sides by 5
x=-17
so x+2=-15
x+4=-13
x+6=-11
x+8=-9
so they are (-9,-11, -13, -15, -17)
