I think it is $37.10 but i am not sure.
Answer:
<u>n=-6</u>
Step-by-step explanation:
First, distribute the 5 and the -
5n+20-n-7=-11 now combine like terms,
4n+13=-11 subtract 13 from each side
4n=-24 divide by 4
/4 /4
<u>n=-6</u>
The answer is C :108! have a good night
Answer:
It will take 4 hours to dig in the garden
Step-by-step explanation:
First we have to calculate the diameter, for this we will use the formula to calculate the circumference of a circle and we will clear the diameter
d = diameter
π = 3.14
c = circumference
c = π * d
d = c / π
d = 88yd / 3.14
d = 28.025yd
round to the nearest whole number
28.025 = 28
d = 28yd
To know how many hours it takes, we divide the diameter by the speed
t = time
v = velocity
t = d / v
t = (28yd) / (7yd/h)
t = 4h
It will take 4 hours to dig in the garden
