Can someone help me please

Answer:

h = 16 cm

Step-by-step explanation:

Given that,

The area of a trapezium, A = 512 cm²

The sum of the length of the parallel sides = 64 cm

The area of a trapezium is given by :

[tex]A=\dfrac{1}{2}\times \text{sum of parallel sides}\times height\\\\h=\dfrac{2A}{Sum}\\\\=\dfrac{2\times 512}{64}\\\\=16\ cm[/tex]

So, the distance between the parallel sides is 16 cm.

Answer:

4846.59

Step-by-step explanation:

21/2= 10.5 as your radius

10.5^3(3.14)(4/3) = 4846.59

Answer:

y= [tex]\frac{2}{5}[/tex]x -3

Step-by-step explanation:

slope-intercept form is y=mx+b

m= slope

b= y-intercept

so plugin your numbers with the given data...

and you get y=2/5x-3

For the graph, you start at -3 on the y-intercept and then move right 5 and up 2

Graph is the picture below :)

Answer:

- [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

One cubic down and 2 cubics to the right

Answer:

Step-by-step explanation:

The 3 angles must add up to 180. So

6x + 4x + 2x = 180

12x = 180

x = 15

Plug this into all the angles and you have your answers

Answer:

Step-by-step explanation:

The sum of a triangles angles is always 180 degrees.

2x+4x+6x=180

12x=180

x=15

A=6x=6(15)=90 degrees

B=2x=2(15)=30 degrees

C=4x=4(15)=60 degrees

Answer:43.2

Step-by-step explanation:

Answer:

Step-by-step explanation:

4x + 3y = 6 -----------------(I)

4x - y =2 ---------------------(II)

Multiply (II) by (-1) and  then add

(I)                4x + 3y = 6

II) *(-1)        - 4x + y  = - 2   {Now add, x will be eliminated}

                         4y = 4

                           y= 4/4

y= 1

Plugin y =1 in equation (I)

4x +3*1 = 6

4x + 3 = 6

      4x = 6- 3

      4x = 3

        x = 3/4

Answer:

( [tex]\frac{3}{4}[/tex], 1 )

Step-by-step explanation:

Given the 2 equations

4x + 3y = 6 → (1)

4x - y = 2 → (2)

Subtract (2) from (1) term by term to eliminate x

4x - 4x + 3y - (- y) = 6 - 2, that is

4y = 4 ( divide both sides by 4 )

y = 1

Substitute y = 1 into either of the 2 equations and solve for x

Substituting into (1)

4x + 3(1) = 6

4x + 3 = 6 ( subtract 3 from both sides )

4x = 3 ( divide both sides by 4 )

x = [tex]\frac{3}{4}[/tex]

solution is ( [tex]\frac{3}{4}[/tex], 1 )

plreae help me

Answer:

I think it is B sorry if I got it wrong

Answer:

Step-by-step explanation:

base b = 7

slant height = L

area of base = 49 cm²

lateral area = surface area - base area = 209 - 49 = 160 cm²

area of one lateral face = 160/4 = 40 cm²

½·b·L = 40

L = 80/7 ≅ 11.4 cm

Answer:

It would be absolute value I think :)

so, you just use the x's from the table and plug them into the equation to find the y.

y=(1)+9

y=10

y=(2)+9

y=11

y=(3)+9

y=12

y=(4)+9

y=13

i hope this helps :)

Answer:

Step-by-step explanation:

He opens the account with $100 so the line would start on a 100 then he adds $25 each month meaning that the line should go up by 25 three times for the three different months he adds $25 The line should stay constant (not moving) for the next five months because he made no deposits, then finally for the next month, the line should dip down to 50 because it states his final amount of money in the account was $50.

Answer:

34in

Step-by-step explanation:

Given data

Length= 21in

Area= 714 in^2

The shape of the doormat is rectangular

Area= Length*Width

substitute

714=21* W

W= 714/21

W= 34in

Hence the widht is 34in

The Triangle EHL and MPE by HL Congruence Rule.

Two triangles are said to be congruent if their sides and angles are the same length. Two triangles can thus be stacked side by side and angle by angle.

Two triangles are said to be congruent if their sides are the same length, their angles are the same measurement, and they may be superimposed on each other.

As, from the figure in Triangle EHL and MPE

EH = MP

EL = ME

<EHL = < MPE = 90

As, If the hypotenuse and a leg of one right triangle are congruent with the hypotenuse and leg of another right triangle, the triangles are congruent.

So, the Triangle EHL and MPE is Congruent by HL Congruence Rule.
