Answer:
SA= 678.24 in^2
Step-by-step explanation:
SA = (pi)(r^2) + (pi)(r)(l)
r = radius
h = height
l = slant height
Pi = 3.14
Slant height:
l^2 = h^2 + r^2
l = sqrt (144+81)
= 15
SA = (pi)(9^2) + (pi) (9) (15)
SA = 254.34 + 423.9
SA= 678.24 square inches
If the slant height of the cone is 15 inches. Then the surface area of the cone will be 678.58 square inches.
How do find the surface area of some object?Find the area that its outer surfaces possess. The Sum of all those surface areas is the surface area of the considered object.
If a right cone has a radius of 9 inches and a height of 12 inches.
Then the surface area of a right cone will be
The slant height is given as
l² = 9² + 12²
l² = 81 + 144
l² = 225
l = 15
Then the surface area will be
Surface area = πr² + πrl
Surface area = π x 9² + π x 9 x 15
Surface area = 81π + 135π
Surface area = 216π
Surface area = 678.58 square inches

Unicorns love eating jelly beans! If a unicorn eats 410.7 ounces of jelly beans 6 times a day, how many ounces does it eat in one day?
Answer:
2464.2
Step-by-step explanation:
you multiply 410.7 by 6 to get this
The ounces of jellybean eaten in a day is required.
The amount of jellybean the unicorns eats in one day will be 2464.2 ounces.
The ounces of jellybean eaten at one time is 410.7 ounces
The number of times jellybean is eaten during one day is 6 times.
[tex]1\ \text{time}=410.7\ \text{ounces}[/tex]
So, for 6 times

Please can I check with you the answer for nbr 12?
Is it correct?
Answer:
B and C
Step-by-step explanation:
B = 2,4,6 =3,6C= 2,4,6,8,10,12 = 6,12Data were recorded for a car’s fuel efficiency, in miles per gallon (mpg), and corresponding speed, in miles per hour (mph). Given the least-squares regression line, , what is the fuel efficiency for a speed of 60 mph?
3.65 mpg
33.90 mpg
36.52 mpg
38.55 mpg
The least-squares regression line equation gives the line that approximate the relationship between the variables in the fuel efficiency data
The fuel efficiency when the speed is 60 mph is approximately 38.55 mpg.
Reason:
The given least-squares regression line equation is presented as follows;
ln(Fuel Efficiency) = 1.437 + 0.541 × ln(speed)
Required:
The value of the fuel efficiency for a speed of 60 mph.
Solution:
The general form of the least-squares regression line equation is [tex]\hat y[/tex] = a + b·x
Where, in the current question, we have;
[tex]\hat y[/tex] = The predicted value = ln(Fuel Efficiency)
a = The y-intercept = 1.437
b = The slope = 0.541
x = The input value = ln(speed)
When the speed = 60 mph, we have;
ln(Fuel Efficiency) = 1.437 + 0.541 × ln(60) = 3.65204040816
Therefore;
[tex]Fuel \ Efficiency = e^{(1.437 + 0.541 \times ln(60))} \approx 38.55[/tex]
The fuel efficiency when the speed is 60 mph ≈ 38.55 miles per gallon

i need step by step explanition if you can. paper depot is delivering 952 cases of paper today.300 of the cases are plain white paper twenty-eight trucks are being loaded with an equal number of cases of paper. how many cases will each truck carry
Answer:
34
Step-by-step explanation:
We actually don't care what amount of paper is white, we just need the amount per truck. If there were 2 trucks, they would each take half of the total amount of paper. If there were 3 trucks, they would each take a third of the total amount of paper. And so on for 4,5,6,etc.
For 28 trucks, they would each take a twenty-eighth of the total amount of paper. So, the amount each truck takes is just [tex]952/28=34[/tex].
So, the answer is [tex]\boxed{34}[/tex] and we're done!
how do you solve this (first equation) x=2y-1 (second equation) x+y=40
Answer:
[tex]x = 26 \frac{1}{3} \\ [/tex]
[tex]y = 13 \frac{2}{3} \\ [/tex]
Step-by-step explanation:
x = 2y - 1
x - 2y = -1 ________(1)
x + y = 40________(2)
(2) - (1)
[tex]x + y - (x - 2y) = 40 - ( - 1) \\ x + y - x + 2y = 40 + 1 \\ 3y = 41 \\ y = \frac{41}{3} \\ y = 13 \frac{2}{3} \\ [/tex]
y = 13 2/3
[tex]x + y = 40 \\ x + 13 \frac{2}{3} = 40 \\ x = 40 - 13 \frac{2}{3} \\ x = 40 - \frac{41}{3} \\ x = \frac{3(40) - 41}{3} \\ x = \frac{120 - 41}{3} \\ x = \frac{79}{3} \\ x = 26 \frac{1}{3} \\ [/tex]
