The total of her first six quizzes is 75*6 = 450
Let her seventh score be x
The total of her seven quizzes be 450+x
Then, (450+x)/7 = 77
x = (77*7) - 450 = 89
Her seventh score is 89
x =
The largest radius for the swimming pool is 15.1 feet
Step-by-step explanation:
Step 1:
Circumference of the circular swimming pool built by Dan = 95 feet
We need to determine the largest radius for the pool.
Step 2 :
Circle's circumference is given by 2πr
Where r represents the radius
This shows that the radius is in direct proportion to the circumference. Hence the radius corresponding to the maximum circumference will be the largest possible radius
So we have 2πr = 95
=> r =
=> r = × where
=> r = 15.1 feet (rounded off to tenth of a foot)
Step 3 :
The largest radius for the swimming pool is 15.1 feet
1/4 1/8 1/16 anything below 2/4 anything below 5/10 its not awful if you just go below the top number and keep the bottom
Answer:
Alexis: 2.5x
Gary: x
James: x + 18
Total: (2.5x) + (x) + (x + 18)
= 4.5x + 18
Bonus:
4.5x + 18 = 1206
4.5x = 1188
x = 264
Alexis: 2.5(264) = 660
Gary: 264
James: 264 + 18 = 282
So there are 12 inches in a foot 51 divided by 12 = 4 feet with a remainder of 3 inches do you understand?
