Thanks

Step-by-step explanation:

Answer/Step-by-step explanation:

Volume of a cone = ⅓*π*r²h

Where,

Radius (r) = 7 mm

Height (h) = 8 mm

Plug in the value into the equation

V = ⅓*3.14*7²*8

V = ⅓*3.14*49*8

V = 410.293333

V ≈ 410.3 mm³ (nearest tenth)

Answer:

D

Step-by-step explanation:

first find the perimeter of both triangles

Original perimeter: 72 in

scaled perimeter: 24 in

A is wrong since the scaled perimeter is actually smaller.

B is wrong because its not 6 times smaller

C is wrong since it's not 1/9 of the original

D is correct since the scaled is a 1/3 of the original perimeter (72*1/3 = 24)

Answer:

44

Step-by-step explanation:

Basically, just substitute t for the value you were given, in this case, 4.

3*4^2 - 4

Do exponents first:

3*16 - 4

Multiply next

48-4

Subtract

44

I have attached a picture of the double cone.

I have also attached the options missing.

Answer:

Option B is correct

Step-by-step explanation:

From the image of the double given, when we cut a section vertically through the centre where the tips of the cones meet, when we look at the cut section, we will not see curves but straight lines meaning that the top and bottom will be horizontal lines and not curves.

Also, the meeting point of the two cone tips will remain the same.

Looking at the options, the only one that fulfills the condition is option B.

B

Answer:

Hello! answer:

Step-by-step explanation:

6 × 12 = 72

6 × 12 = 72

3 × 12 = 36

3 × 12 = 36

3 × 6 = 18

3 × 6 = 18

72 + 72 + 36 + 36 + 18 + 18 = 252 therefore the surface area would be 252 hope that helps!

Answer:

252 in²

Step-by-step explanation:

You have to calculate the area of each surface and sum all they after:

Top area: 6 × 12 = 72 in

Front area: 3 × 12 = 36 in

Side area: 6 × 3 = 18 in

You have 2 rectangles with the same measure of the top, of the side and the front, so multiply each area per 2:

72 × 2 = 144

36 × 2 = 72

18 × 2 = 36

Now you sum all the areas:

144 + 72 + 36 = 252 in²

Answer:

x = - 8

Step-by-step explanation:

x - 124 = 9(2x + 3) - 15

x - 124 = 18x + 27 - 15

x - 124 = 18x + 12

x - 124 + 124 = 18x + 12 + 124

x = 18x + 136

x - 18x = 18x - 18x + 136

- 17x = 136

- 17x ÷ - 17 = 136 ÷ - 17

x = - 8

Answer:

b

Step-by-step explanation:

Answer:

So the point of intersection would be -x=2x+6

and then we'll subtract 2x on both sides and get -3x=6

this will result in x=-2

Then we'll substitute that into y=-x, so y=2

Therefore the point of intersection is (-2,2)

Hope I helped, have a nice day :)

Answer:

SOHCAHTOA

-opposite = 45

adj = x (32 degrees)

Tan(32)/x = 45/x

cross multiply to get your answer

Answer:

z = 45 (it is the same angle as x)

y and u = 135

Step-by-step explanation:

45 + 45 = 90

360 - 90 = 270

270/2 = 135

CHECK YOUR WORK:

135 + 135 + 45 + 45 = 360

270 + 90 = 360

360 = 360

Answer:

z = 45

y = 135

u = 135

Step-by-step explanation:

Vertically opposite angles are equal so x and z must be the same.

A circle is 360 degrees so

360 - (45 + 45) = 270

270 / 2 = 135 degrees

This means that y and u must both be 135 as they too are vertically opposite.

Answer:

answer is 40 :)

Answer:

First one is 120, second is 185

Step-by-step explanation:

So basically it is literally just segmenting the object into rectnagles and squares.

From there, we can subtract and use different side lengths to find the width and length of the segmented pieces.

Hope this makes sense!

Step-by-step explanation:

tan(7π/6)

tan(180*7/6)

tan(30*7)

tan(210)

tan(360-150)

-tan 150

-(-1/[tex]\sqrt{3[/tex])

1/[tex]\sqrt{3[/tex]

Step-by-step explanation:

[tex] \tan( \frac{7\pi}{6} ) \\ = \tan( \pi + \frac{\pi}{ 6} ) \\ = \tan( \frac{\pi}{6} ) [/tex]

as this angle lies in the third quadrant and tan x is positive in the third quad.

[tex] = \frac{1}{ \sqrt{3} } \\ as \: the \: value \: of \: \tan( \frac{\pi}{6} ) = \frac{1}{ \sqrt{3} } \\

\frac{1}{ \sqrt{3} } ×\frac{\sqrt{3}}{ \sqrt{3} }\\

= \frac{\sqrt{3} }{ 3 } [/tex]

Step-by-step explanation:

so you put the value of F into x and make an equation

Answer:

Step-by-step explanation:

f(x) = px + q

f(-2) = 4

 p*(-2) + q = 4

-2p + q = 4 -----------------(I)

                    f(3) = 4

                    p*3 + q = 4

                     3p + q = 4 ---------------------(II)

Subtract equation (II) from (I)

(I)           -2p + q = 4

(II)           3p  + q = 4  {Subtract}

           -         -      -  

              -5p + 0 = 0

-5p = 0

p = 0

Plugin p = 0 in equation (I)

0 + q = 4

       q = 4

p = 0

q = 4

Answer:

b) x=2

Step-by-step explanation:

The axis of symmetry is what straight line would divide the parabola directly in half.

Answer:

A. -1.5 B.2

Step-by-step explanation:

The Axis of symmetry is the line that goes through the center of the parabola. And resembles a symmetrical shape that makes the parabola look the same on both sides.

In this case for A, -1.5 would be the answer because it is in the center of the parabola on the x-axis. For B, 2 is the axis of symmetry because it lines up in the center of the parabola.

Answer:

The polygons are similar.

Step-by-step explanation:

By definition, the corresponding sides and angles of similar polygons must be in some constant proportion.

Therefore, we can find the ratio between corresponding sides to see if that ratio is maintained.

The side marked 3 cm in the smaller figure corresponds with the side marked 3.75 cm in the larger figure. This proportion is [tex]\frac{3}{3.75}[/tex].

The side marked 5 in the smaller figure corresponds with the side marked 6.25 cm in the larger figure. This proportion is [tex]\frac{5}{6.25}[/tex].

If these polygons are similar, these proportions must be equal.

[tex]\frac{3}{3.75}=\frac{5}{6.25},\\0.8=0.8\:\checkmark[/tex]

Checking, we see that these proportions are equal, and therefore the polygons are similar.

Answer:

p³+2; 29 plants

Step-by-step explanation:

Hi there!

Find the expression to represent the total number of plants in her garden

p

First, we're told that Iliana cubed the number of flowering plants in her garden. This means she raised the original number of plants by an exponent of 3.

p³

Then, we're told that she added 2 vegetable plants.

p³+2

Find the number of total plants if p=3

p³+2

= (3)³+2

= 27+2

= 29

Therefore, Iliana now has 29 plants in total.
