Answer:The value of the surface area (in square centimeters) of the cone is equal to the value of the volume (in cubic centimeters) of the cone. The formula for the surface area S of a cone is S=πr2+πrl, where r is the radius of the base and l is the slant height.

Step-by-step explanation:

Answer:

A cone is 360 triangles rotated in a circle, so find the hypotenuse of the triangle and multiplying it by 360 you would get the surface area of the cone

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

You order all the numbers from least to greatest and the center number/s is the median.

If two numbers are in the center, you add them up and divide by 2

The median for this set was 4 and 4. We add those numbers (4+4=8) and divide the sum by 2. We get 4 as the answer

Answer:

3(4+√2)

Step-by-step explanation:

Here we need to find the perimeter of the given figure. Here the given figure is made from a triangle and a square. The side lenght of the square is 3. We need to find the hypontenuse of the triangle in order to find Perimeter .

• Using Pythagoras Theorem :-

⇒ h² = p² + b²

⇒ h² = 3² + 3²

⇒ h² = 9 + 9

⇒ h² = 18

⇒ h = √[ 9 × 2 ]

⇒ h = 3√2 .

Therefore the perimeter will be ,

⇒ P = 3√2 + 3 + 3 + 3 + 3

⇒ P = 3√2 + 12

⇒ P = 3( 4 + √2)

wait wait wait I feel like I did this before but I don't at the same time-

I have no brain too so yeah sorry- :((

Answer:

30

Step-by-step explanation:

20+11=31

It can't be exactly 31 but it can be any number less than 31, so the nearest whole number down is 30

Answer: should be no solution

Step-by-step explanation:

There are no values of x

Answer:

Mean and Median

Step-by-step explanation:

Given the data :

285,288,289,290,299,300,308,309,312,314

To summarize the data using a measure of centre, considering that the dataset doesn't show a great deal of variation we could use either the mean or median value.

The mean, x = Σx / n

n = sample size = 10

Σx = 2994 ; n = 10

x = 2994 / 10 = 299.4

Also the median value ;

1/2 * (n + 1)th term

1/2 * (10 + 1)th term

1/2 * 11

= 5.5 th term

= (5 + 6)th / 2

= (299 + 300) / 2

= 299.5

Answer:

the slope equals 2. otherwise known as the coefficient of x.

Answer:

6216

Step-by-step explanation:

This problem deals with exponential growth.

Final value: F

Present (initial) value: P

Rate of growth: r

Time in years = t

[tex] F = P(1 + r)^t [/tex]

[tex] F = 2900(1 + 0.1)^8 [/tex]

[tex] F = 6216 [/tex]

Answer: 6216

Answer:

1. 5.6%

2. 15%

3. 300 seats

4. 2.3%

Step-by-step explanation:

1. Percent error is A-E/E*100

A is actual and e is expected

376-356/356= 0.05618*100= 5.6%

2. 17-20/20=-0.15*100= 15%

3. This time we have to solve for the actual

x-250/250*100=20

x=300 seats

4. 342-350/350=-0.0228571429*100= 2.3%

Answer:

Step-by-step explanation:

The answer would be (G)

The value of w is greater than -4 which will best represent the inequality 3.3w - 9 > -22.27 on number line.

Number lines are simple, visual pictures of how the values of numbers increase and decrease.

Given an inequality 3.3w - 9 > -22.27

On solving, we get,

3.3w - 9 > -22.27

3.3w > -22.27 + 9

3.3w > -13.27

w > -4

Hence, the value of w is greater than -4 which will best represent the inequality 3.3w - 9 > -22.27 on number line.

Answer:

  4 ft = height

  10 ft = base

Step-by-step explanation:

The area of a triangle is given by ...

  A = 1/2bh

Filling in the given value, we get the relation ...

  20 = 1/2bh

  40 = bh

We know the factors of 40 are ...

  40 = 1×40 = 2×20 = 4×10 = 5×8

Of the numbers that area available, only the pair 4×10 will give the desired result.

The height is 4 ft; the base is 10 ft.

Answer:

#12.) 3m+2=17

3(5)+2=17

5*3=15

15+2=17

Step-by-step explanation:

Answer:

3 x 2 + 5 - 4 = 7 if its not 7 then try 15 most likely 7

m = 5 its already given on the top or its 17

7 x 5 - 2 > 12, m = 5 or the answer is 33 for the left side

for this you need to draw an empty circle on two and make the line bold starting from 2 to the 10.

Answer:

The point crosses over the y-axis

Step-by-step explanation:

Given

A change in the sign of x coordinate

Required

The effect on the point location

Assume the coordinate to be (x,y).

The above point is located in the first quadrant,

When the x value changes to negative i.e. (-x,y)

The point moves from the first quadrant to the second quadrant

This implies that, the point crosses over the y-axis.

Similarly, assume the coordinate to be (-x,-y).

The above point is located in the third quadrant,

When the x value changes i.e. (x,-y)

The point moves from the first quadrant to the fourth quadrant

This implies that, the point crosses over the y-axis.
