Dead asl (can't keep replying stop blowing my shii up)

YYYYYYYYYYYEEEEEEEEEEEEEERRRRRRRRRRRRRRRR WSG MAMAS I  MISSD U BRU FR ITS BEEN TOO LONG

Answer:

how

Step-by-step explanation:

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:

[tex]4^{-5}[/tex]

Step-by-step explanation:

The given expression is :

[tex]4^{-3}\times (\dfrac{1}{4})^2[/tex]

We know that, [tex]x^{-a}=\dfrac{1}{x^a}[/tex]

So,

[tex]4^{-3}\times (\dfrac{1}{4})^2=\dfrac{1}{4^3}\times (\dfrac{1}{4})^2\\\\=\dfrac{1}{4^3}\times \dfrac{1}{4^2}\\\\=\dfrac{1}{4^3\times 4^2}\\\\=\dfrac{1}{4^{3+2}}\\\\=\dfrac{1}{4^5}\\\\=4^{-5}[/tex]

So, the answer of the given expression is equal to [tex]4^{-5}[/tex].

Answer:

  a. 123.2 cm²

  b. 136 m²

Step-by-step explanation:

Use the formulas.

a) The formula is ...

  SA = 2πr(r+h) . . . . where r is half the diameter, and h is the height.

  SA = 2π(2 cm)(2 cm +7.8 cm) = 2·2·9.8π cm² = 123.2 cm²

__

b) The formula is ...

  SA = 2(LW +H(L+W))

  SA = 2((8 m)(3 m) +(4 m)(8 m +3 m)) = 2(24 m² +44 m²) = 136 m²

_____

For the cylinder, we used the "pi button" and rounded to tenths. If you use 3.14 for π, you get 123.1 cm² when rounded to tenths.

Answer:

[tex]\text{a. }123.2\:\mathrm{cm^2},\\\text{b. }136\:\mathrm{m^2}[/tex]

Step-by-step explanation:

Part A:

The total surface area of the cylinder consists of two circular bases and a side area. The area of a circle is given by [tex]A=r^2\pi[/tex], where [tex]r[/tex] is the radius of the circle. Since the diameter is given as 4 cm, the radius must be 2 cm.

Area of two circular bases: [tex]2\cdot 2^2\pi=8\pi=25.1327412287[/tex]

Area of side: [tex]7.8\cdot 2\cdot 2\cdot \pi=31.2\pi=98.017690792[/tex]

Therefore, the cylinder's total surface area is [tex]25.1327412287+98.017690792=123.150432021\approx \boxed{123.2\:\mathrm{cm^2}}[/tex]

Part A:

The total surface area of a rectangular prism with width [tex]w[/tex], length [tex]l[/tex], and height [tex]h[/tex] is given by [tex]2(hl+hw+lw)[/tex].

Thus, the total surface area of the rectangular prism is [tex]2(4\cdot 8+4\cdot 3+8\cdot 3)=2(32+12+24)=2(68)=\boxed{136\:\mathrm{m^2}}[/tex]

Answer:

Since 7 and 11 are both rational, the sum and difference are rational.

Step-by-step explanation:

A. Since 7 and 11 are both rational, the sum and difference are rational.

B. Since 14 and 11 are both rational, the sum and difference are rational.

C. Since 7 is rational and StartRoot 11 EndRoot is irrational, the sum and difference are irrational.

D. Since StartRoot 7 EndRoot is irrational and 11 is rational, the sum and difference are irrational.

p² – 14p – 72 = 0

p² – 14p = 72

p² – 14p + 49 = 72 + 49

p² - 14p + 49 = 121

(p - 7)² = 121

find the square root of both sides

√(p - 7)² = √121

p - 7 = ±11

p = +11 - 7 or p = -11 - 7

p = 4 or -18

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)

Confused a bit, can you make sure you copy and pasted it right?

Answer:

I guess no.B is the answer....

Hope it helps:)

Unfortunately there isn't enough information.

Check out the diagram below. We have segment BC equal to 120 meters long. Points B, C, D and E are all on the edge of the same circle. According to the inscribed angle theorem, angles BDC and BEC are congruent. This shows that the surveyor could be at points D or E, or the surveyor could be anywhere on the circle. There are infinitely many locations for the surveyor to be at, which leads to infinitely many possible widths of this canal.

tan(180*7/6)

tan(30*7)

tan(210)

tan(360-150)

-tan 150

-(-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} }\\

Answer:

a) x=-1.5

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:

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.

I hope this helps!

Answer:

D

Step-by-step explanation:

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:

perimeter = 18 units

area = 20 square units.

Step-by-step explanation:

We know that a rectangle is defined by two measures, length L, and width W.

Such that the perimeter is given by:

P = 2*(L + W)

and the area is given by:

A = L*W

Here we know that the vertices of or rectangle are:

(-1, 6)

(-1, 2)

(4, 2)

(4, 6)

Here you can see that we have just two different values of x (-1 and 4) and two different values of y (6 and 2)

So we can define the length L as the difference between the two different values of x:

L = 4 - (-1) = 4 + 1 = 5 units

And the width as the difference between the two different values of y:

W = 6 - 2 = 4 units

A graph of the rectangle can be seen below, to see why I choose to define the length and width in this way.

Now that we know the measures of our rectangle, and using the above formulas for perimeter and area, we get:

P = 2*(W + L) = 2*(5 + 4) = 18 units

A = W*L = 5*4 = 20 square units

Answer:

Option B is correct

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.

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
