Surface = 2 x PI x r x H + 2 x PI x r^2
= 2 x r x h + 2 x r^2
= 2 x 6 x 12 + 2 x 6^2
= 144 + 72
= 216 PI in^2
Answer is A
Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
y = x² + 2x + 7 → (1)
y - 7 = x → (2)
Rearrange (2) expressing y in terms of x by adding 7 to both sides
y = x + 7 → (3)
Substitute y = x + 7 into (1)
x + 7 = x² + 2x + 7 ( subtract x + 7 from both sides )
0 = x² + x ← factor out x from each term
0 = x(x + 1)
Equate each factor to zero and solve for x
x = 0
x + 1 = 0 ⇒ x = - 1
Substitute these values into (3) for corresponding values of y
x = 0 → y = 0 + 7 = 7
x = - 1 → y = - 1 + 7 = 6
The solutions are
(- 1, 6 ) and (0, 7 )

put the numbers in oreder of smallest to largest
Median is the middle so would be 6
The range is biggest- smallest so would be 9-0 aka 9
The mode is the most so there are 4 7s so it would be 7
If you divide 120,000 by 1,500 you will get the amount that it costs per square feet which you would then multiply by 2,400 to get 192,000. So the answer is $192,000
Answer:
.62 cents per box
Step-by-step explanation:
Take the total cost and divide by the number of boxes to get the unit cost
4.98 / 8
.6225 per box
It states to round to the nearest cent
.62 cents per box
