Answer:

900 square feet :)

Step-by-step explanation:

plz give brainliest

Answer:

30 cm

Step-by-step explanation:

1. Given the length, width and tallness discover the volume, surface region and inclining of a rectangular crystal  

h, l and w are known; discover V, S and d  

V = lwh  

S = 2(lw + lh + wh)  

d = √(l2 + w2 + h2)  

2. Given the surface region, length and width discover the tallness, volume and askew of a rectangular crystal  

S, l and w are known; discover h, V and d  

h = (S - 2lw)/(2l + 2w)  

V = lwh  

d = √(l2 + w2 + h2)  

3. Given the volume, length and width discover the stature, surface territory, and slanting of a rectangular crystal  

V, l and w are known; discover h, S and d  

h = V/lw  

S = 2(lw + lh + wh)  

d = √(l2 + w2 + h2)  

4. Given the inclining, length and width discover the tallness, volume and surface space of a rectangular crystal  

d, l and w are known; discover h, V and S  

h = √(d2 - l2 - w2)  

V = lwh  

S = 2(lw + lh + wh)

Answer:

Volume=8

Step-by-step explanation:

[tex]volume[/tex]⇒[tex]\frac{1}{3}[/tex]×[tex](\frac{1}{2}[/tex]×[tex]3[/tex]×[tex]4^{2}[/tex]×[tex]4)[/tex]

⇒[tex]\frac{1}{3}[/tex]×[tex]3[/tex]×[tex]8[/tex]

[tex]Answer:8[/tex]

Multiplying the two together, you get an equation such as

-6x^4 - 12x^3 +33x^2 +12x -27.

Answer:

384 cm^2

Step-by-step explanation:

A = 6a^2    (a = side length)

A = 6(8^2)

A = 6(64)

A = 384 cm^2

More explain stuff:

a^2 is what is used to find the area of a 2 dimensional square. You can also use a · a. Remember, a = side length. Since there are 6 sides/faces in a cube, you multiply the area of each face by 6. :D

Answer:

y=8x+1

Step-by-step explanation:

y=mx+b

m=rise/run=(8)/(1)=8

y=8x+b

b is the y-intercept  

y=8x+1

Answer:

5. a) 96ft²

6.  c) 144ft²

Step-by-step explanation:

Answer:

100%

300 students

Step-by-step explanation:

let b = number of students in the school

this equation can be derived = 10% x b = 30

to find b, divide both sides of the equation by 10%

b = 30/0.1 = 300

we want find the total number of students in the school, which is equal to 100%

Answer:

B. a square must have 4 right angles, but a rhombus may or not have 4 right angles.

Answer:

B

Step-by-step explanation:

The main difference between a square and a rhombus is a square must have 4 right angles, but a rhombus may or may not have 4 right angles. All the angles of a square have to be 90 degrees. All right angles are 90 degrees. All squares are rhombuses, but not all rhombuses are squares. There are occasions when a rhombus has 4 right angles.

Answer:

It would be 900

Answer:

The anwser is -1/2

Step-by-step explanation:

A trick i personally learned is that is you are shrinking then it will turn up as a fraction, but make sure that fraction is not an improper fraction and if the dialation does get bigger it will be a whole number or improper fraction.

Answer:

267x2 -8x -8 where

x=- 4± 2√ 538/267

Step-by-step explanation:

x2 - 2x -89x2 - 16x2 - 163x2 + 10 x + 8

= x2  -89x2 - 16x2 - 163x2  - 2x+ 10 x + 8

= -267x2+8x +8

= 267x2 -8x -8

First the like terms are arranged and then added . All the co efficients of x2 are added and x are added separately.

Using the quadratic equation to find the value of x

a= 267 , b= -8 and c= -8

x= -b±√b²- 4ac/ 2a

x= -8±√64 +8544/534

x= -8±√8608/534

x=-8±√ 2 x 2 x 2 x 2 x 2 x 269/534

x=-8± 4√ 2 x 269/534

x=- 4± 2√ 2 x 269/267

x=- 4± 2√ 538/267

Answer:

See Below.

Step-by-step explanation:

We are given that ABC is a triangle in which AB = AC.

A circle passing through B and C also intersects the sides AB and AC at points D and E respectively.

And we want to prove that AD = AE.

By the secant-secant theorem (shown below), we know that:

[tex]AD(AB)=AE(AC)[/tex]

We are given that AB = AC. So, by substitution:

[tex]AD(AB)=AE(AB)[/tex]

And by dividing both sides by AB (AB ≠ 0), we acquire:

[tex]AD=AE[/tex]
