25 letters for first spot
25 letters for second spot
$25 ^{2} = 625$
9 numbers
$9 ^{4} = 6561$
6561 times 625
=4,100,625

Each lenght is in metres Calculate DC

Gnom [1K]

Step-by-step explanation:

ED is greater than BC

the line from B to ED ^ (which i drew ) the point it touches ED name it X. so EX will be 2 ( ED-BC)(6-4).

then u have a triangle. EX, XB and EB.

you have length of EX(2) and u have hypotenuse. so u can calculate XB using Pythagoras theorem.

15.1²=2²+XB²

15.1²-2²=XB²

224.01=XB²

XB=14.97

since XB and DC are parallel ( a rectangle is forming XBCD) so DC is also 14.97

50% of 80 solve pls show working<br>pls I know it just try working it

Eduardwww [97]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{40}}}}}$

Step-by-step explanation:

$\sf{50 \: \% \: of \: 80}$

To convert the percent into a fraction , divide it by 190 and remove the % symbol. Then , Simplify the fraction to its lowest term.

⇒ $\sf{ \frac{50}{100} \times 80}$

⇒ $\sf{ \frac{1}{2} \times 80}$

Divide 80 by 2

⇒ $\sf{40}$

Hope I helped!

Best regards!!

Lexi2984 can u help me with this question

arsen [322]

9514 1404 393

Answer:

see the attachment

Step-by-step explanation:

The x- and y-intercepts are easily found:

<u><em>X-intercept</em></u>

Set y = 0 and divide by the coefficient of x.

-x +0 = 8

x = -8

__

<u><em>Y-intercept</em></u>

Set x = 0 and divide by the coefficient of y.

0 -2y = 8

y = -4

__

Now, we have two points on the graph: (-8, 0) and (0, -4). A third point can be one that is halfway between these: (-4, -2). The graph is attached.

Given ADEF: ARST, find the scale factor

Deffense [45]

Answer:

the scale factor is 3/4

x = 16×3/4 = 12

Step-by-step explanation:

the only side length we have for both triangles is the short left side.

we see that we get ED from SR and need to transform 4 into 3. how do we do that ?

well,

4×f = 3

f = 3/4

that is the scaling factor, as all side lengths in EDF are created by multiplying the corresponding side in SRT by the same scaling factor (3/4).

therefore,

x = EF = ST×f = 16×3/4 = 4×3 = 12
