Answer:

81 cm^3

Step-by-step explanation:

We know that we have to use 3 for pi.

Formula given for formula of cone is:

πr^2h ÷3

Use formula with the given pi and dimensions:

3(3^2)(9) ÷ 3

= 3(9)(9) ÷ 3

= 243 ÷ 3

= 81

Volume is measured in cubic centimeters.

FINAL ANSWER:

81 cm^3

Answer:

[tex](x+9)^2+y^{2}=25[/tex]

Step-by-step explanation:

The equation of a circle is [tex](x-h)^2+(y-k)^2=r^2[/tex] where [tex](h,k)[/tex] is the center of the circle and [tex]r[/tex] is the radius of the circle.

Given the circle's diameter is [tex]d=10[/tex], then its radius is [tex]r=\frac{10}{2}=5[/tex].

Therefore, the equation of the circle is [tex](x+9)^2+y^{2}=25[/tex]

Answer:

(3-x) is the other factor.

Step-by-step explanation:

The given function is :

[tex]F(x)=-x^{2}+7x-12[/tex]

One of the factor is (x-4)

We need to find the other factor.

It can be solved as follows :

[tex]F(x)=-x^{2}+4x+3x-12\\\\=(-x+3)(x-4)[/tex]

So, the other factor is (3-x).

Answer:

imagine a triangle

one side is just upwards trough the cone, one side is the radius of the circle and the last one is the slant height.

remember the pythagoras stuff

so

(slantheight)² = radius² + height²

or finally:

slantheight = squareroot (radius² + height²)

Answer:

Step-by-step explanation:

5 red

3 blue

6 white

2 green

total 16 marbles.

Note: P(E) = probability of event E happening

P(~E) = probability of event E NOT happening.

We usually leave probabilities in fractions whenever possible because they will not be subject to round-off errors.

A. choose one marble at random.

P(W) = 6 white / 16 total = 3/8

B. choose one marble at random.

P(~R) = (16-5)/16 = 11/16

C. choose one marble at random, then a second one without replacement,

there will be 3 blue out of 16 at the beginning, then if successful, there will be 2 blue out of 15.

P(BB) = (3/16)*(2/15) = 1 / 40

D. choose two with replacement

5 red out of 16 for first draw, still 5 red out of 16 for second draw.

P(RR) = (5/16)^2 = 25/256

a=10

b=20

c=10[tex]\sqrt{3}[/tex]

x=b

x=20

Answer:

Yes

Step-by-step explanation:

We can see step by step how to solve for x, and get 11.5:

2x+9=32

Subtrract the 9 from both sides. You should always try to get the number on one side, and the variable on the other:

2x+9-9=32-9

=

2x=23

In the end, once the number values are on one side, and the variable value on the other, you want you varaible to be 1.

When I mean 1, I mean you want 1x, or just x.

Here we see 2x=23, meaning we need to divide both sides by 2, to get 1x:

2x/2=23/2

=

x=11.5

So x equals 11.5, and you were correct.

Step-by-step explanation:

Answer:

geometric

arithmetic

Step-by-step explanation:

there are no statements to check. you did not copy them in.

but I can solve the first part of the question.

sequence 1 :

-10, 20, -40, 80, -160, 320, -640, ...

I extended the sequence by a few more terms.

but it is clear that each new term is the previous term multiplied by -2.

since the sequence is built by multiplication, it is geometric.

sequence 2:

15, -5, -25, -45, -65, -85, ...

so, it is clear that each new term is the previous term subtracted by -20.

since the sequence is built by adding or subtracting, it is arithmetic.

Answer:

  -x +2

Step-by-step explanation:

The expression can be simplified as follows.

  [tex]\sqrt{x^2-4x+4}=\sqrt{(x-2)^2}=|x-2|[/tex]

For negative values of its argument, the absolute value changes the sign.

For x < 1, x-2 is negative, so the simplified form is ...

  -(x -2) . . . . . for x < 1

  -x +2 . . . . . for x < 1

Mid - point = ( 2 , 1 )

Step-by-step explanation:

Let A = ( - 4 , 2 ) and B = ( 8 , 0 )

Let P = ( x , y ) be the mid-point of AB

Then,

     [tex]P = (\frac{x_A + x_B}{2} , \frac{y_A + y_B}{2} ) \\\\P =(\frac{-4+8}{2} , \frac{2+0}{2}) \\\\P = ( \frac{4}{2} , \frac{2}{2} )\\\\P = ( 2 , 1)[/tex]

Answer:

(2,1)

Step-by-step explanation:

Hi there!

Midpoint: [tex](\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2} )[/tex] where two endpoints of a line segment are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points (-4,2) and (8,0)

[tex](\frac{-4+8}{2} , \frac{2+0}{2} )\\(\frac{4}{2} , \frac{2}{2} )\\(2, 1)[/tex]

Therefore, the midpoint of the line segment is (2,1).

Answer:

C

Step-by-step explanation:

magic

The region with the competition for resources is region C with the highest population density

The population density, or the number of people divided by the area's size, is determined by the number of people who reside there. Numerous creatures' distribution, growth, and migration can all be explained by population density.

Population density = number of people / the area they occupy

Given data ,

Let the population density be represented as P

Region    Population    Area

A               1,312       212

B               630         314

C               16,400     625

D               17,800      902

Now , the state with the highest population density will have the greater competition for the resources

So , The population density in Region A = 1312 / 212 = 6.19

The population density in Region B = 630 / 314 = 2

The population density in Region C = 16400 / 625 = 26.24

The population density in Region D = 17800 / 902 = 19.7

Hence , the region C has the highest population density

Answer:

32

Step-by-step explanation:

In order to find the measure of angle A we must first find x

If you didn't know, supplementary angles add up to equal 180

Hence, 2x - 16 + 5x + 28 = 180

( Note that we just created an equation that we can use to solve for x )

We now solve for x using the equation that we created

2x - 16 + 5x + 28 = 180

Combine like terms

7x + 12 = 180

Subtract 12 from both sides

7x = 168

Divide both sides by 7

We're left with x = 24

Now to find Angle a

To find Angle A we simply substitute 24 for x in 2x - 16

* Substitute 24 for x *

2(24) - 16

Multiply

48 - 16

subtract

Answer:

A) 0.265

B) 0.0265

C) 0.837

D) 0.0837

E) 0.00265

F) 0.00837

Step-by-step explanation:

We are given;

√7 = 2.65 and √70 = 8.37

A) √0.07 can be rewritten as;

√(7 × 1/100)

Let's deal with the digits in the bracket.

Square root of 100 is 10. Thus;

√(7 × 1/100) = (1/10)√7 = (1/10) × 2.65 = 0.265

B) √0.0007

Rewrite to get;

√(7 × 1/10000)

Square root of 1/10000 is 1/100

Thus;

√(7 × 1/10000) = (1/100)√7 = (1/100) × 2.65 = 0.0265

C) √0.7

Like above;

√0.7 = √(70 × (1/100))

>> (1/10)√70 = (1/10) × 8.37 = 0.837

D) √0.007

Like above;

Rewrite to get;

√(70 × 1/10000)

Square root of 1/10000 is 1/100

Thus;

√(70 × 1/10000) = (1/100)√70 = (1/100) × 8.37 = 0.0837

E) √0.000007

Rewritten to;

√(7 × (1/1000000))

√(1/1000000) = 1/1000

Thus; √(7 × (1/1000000)) = 1/1000 × √7 = 1/1000 × 2.65 = 0.00265

F)√0.00007

Rewritten to;

√(70 × (1/1000000))

√(1/1000000) = 1/1000

Thus; √(70 × (1/1000000)) = 1/1000 × √70 = 1/1000 × 8.37 = 0.00837

Answer:

22 exhibits

Step-by-step explanation:

We are told from the above question that:

Sandy went to her local zoo where 50% of it's exhibits featured reptiles.

If the zoo features 44 exhibits in total, then the number of the zoo's exhibits that feature reptiles is calculated as:

50% of 44

50/100 × 44

= 50 × 44/100

= 22

Therefore, the number of the zoo's exhibits that feature reptiles is 22 exhibits.
