The radius of the base of a cone is 4 inches. The slant height of the cone is 6 inches. Which is closest to the surface area of the cone ?
Answer:-Given:-[tex] \bullet [/tex] Radius (r) of the base of a cone is 4 inches.
[tex] \bullet [/tex] Slant height (l) of the cone is 6 inches.
To Find:-Which is closest to the surface area of the cone ?
Solution:-We know,
Formula of surface area of a cone is πr(r + l) sq. units.
Taking value of π = 3.14
So, Surface area of the cone = 3.14 × 4(4 + 6)
Surface area of the cone = 12.56 × 10
Surface area of the cone = 125.6 sq. inches.
[tex] \because [/tex] 126 sq. inches is closest to 125.6 sq. inches.
So, option (H) 126 sq. in is correct. [Answer]
Which answer choice?
Answer:
B or C,i think. I'm not sure though
To model some data, Anne ran a linear regression and found the regression equation to be y=0.554x-0.507.
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]y = 0.554x - 0.507[/tex]
The question is incomplete; however, a possible question could be to interpret the given equation.
The equation is given in slope intercept form i.e. [tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
[tex]b = y\ intercept[/tex]
So, by comparing:
[tex]y = mx + b[/tex] to [tex]y = 0.554x - 0.507[/tex]
[tex]m = 0.554[/tex]
[tex]b = -0.507[/tex]
Hence, the slope of the regression is 0.554 and the y intercept of -0.507

The result of a random survey showed that 40 out of 75 people plan to vote for Mr. Best for a position on the local store school board which is the best prediction of the number of people who vote for Mr. Busan if 3000 people vote
Answer: 1,600 people
Step-by-step explanation:
The survey showed that 40 out of 75 people would vote for Mr. Best.
Convert this figure to a percentage so that you can use it to find out the number of people that would vote for him if numbers were larger:
= 40 / 75
= 53.33%
If 3,000 people voted, 53.33% would vote for Mr. Best which is:
= 3,000 * 53.33%
= 1,599.9
= 1,600 people

Use π=3.14 and round your answer to the nearest hundredth
Answer All of my questions to get 180 points
Answer:
3052.08 m³
Step-by-step explanation:
[tex]\boxed{volume \: of \: sphere = \frac{4}{3}\pi {r}^{3} }[/tex]
Given that the radius is 9m, r=9.
Volume of sphere
[tex] = \frac{4}{3} (3.14)(9^{3} )[/tex]
= 3052.08 m³
Answer:
Solution :-Volume = 4/3 • π • r³
Volume = 4/3 • 3.14 • (9)³
Volume = 4/3 • 3.14 • 9 • 9 • 9
Volume = 4 • 3.14 • 27 • 9
Volume = 3052.08 cm³

Answer:
i havent had this one.
Step-by-step explanation:
1) Find the missing side. Give each
answer in simplest radical form.
Answer:
x = 10
y = 10√2
Step-by-step explanation:
Reference angle = 45°
Opposite = 10
Adjacent = x
Hypotenuse = y
Recall: SOHCAHTOA
✔️Apply TOA to find x:
Tan 45 = Opp/Adj
Tan 45 = 10/x
x = 10/Tan 45
x = 10/1 (tan 45 = 1)
x = 10
✔️To find y, apply SOH:
Sin 45 = Opp/Hyp
Sin 45 = 10/y
y = 10/Sin 45
y = 10/(1/√2) (sin 45 = 1/√2)
y = 10 × √2
y = 10√2

Members of a school sports team are raising money by selling custom water bottles at school activities. They plan to sell each bottle for $13. Each bottle costs them $6. They spend $40 for advertising. Use n to represent the number of bottles they sell. Multiply this by the money they make for each bottle, then subtract the advertising cost. Which expression represents the money that the group raises? O A. 40 - (13 - 6)n O B. (13 - 6) n - 40 O C. 13n - 6 - 40 D. 13-on-40
Answer:
B. (13 - 6)n - 40
Step-by-step explanation:
If each bottle costs them $6 and they are selling each one for $13, the amount of money they make for each bottle can be represented by (13 - 6)n
This is because this finds the profit per bottle, then multiplies it by n, which is the number of bottles they sell.
Then, since they spent $40 on advertising, subtract 40 from this.
The expression will be (13 - 6)n - 40.
The correct answer is B. (13 - 6)n - 40
The expression represents the money that the group raises is (13-6)n - 40
What is expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
According to the question
Members of a school sports team are raising money by selling custom water bottles at school activities.
Let number of bottle they sell = n
Selling price of a bottle = $13
Now ,
Selling price of n bottle = $13n
Cost price of a bottle = $6
Now ,
Cost price of n bottle = $6n
Money spent on advertising = $40
Total they spent on bottles = $6n + $40
Therefore,
Money they raise in expression = 13n - 6n - 40
= (13-6)n - 40
Hence, The expression represents the money that the group raises is (13-6)n - 40
