Answer:

20 = EB

10 = DB

10 = ED

Step-by-step explanation:

By definition, according to this cross-section model, point D is the segment bisector of all segments, according to which segments they are in congruence with. Anyway, here is how it is done:

3x - 8 = x + 4

-3x - 3x

_____________

−8 = −2x + 4

-4 - 4

_____________

−12 = −2x

____ ____

−2 −2

6 = x[Plug this back into all expressions above to get the measurements of 20 = EB, 10 = DB, 10 = ED]

* Since point D the segment bisector, you set the given equations equal to each other, then in the end, plug the x-value back into all expressions to get the length of EB.

I am joyous to assist you anytime.

Answer:

Part 1) ED=10\ units

Part 2) DB=10\ units

Part 3) EB=20\ units

Step-by-step explanation:

we know that

EB=ED+DB

ED=DB -----> given problem

Substitute the given values and solve for x

x+4=3x-8

3x-x=4+8

2x=12

x=6

<em>Find the value of ED</em>

ED=x+4

substitute the value of x

ED=6+4=10\ units

<em>Find the value of DB</em>

Remember that

ED=DB

therefore

DB=10\ units

<em>Find the value of EB</em>

EB=ED+DB

EB=10+10=20\ units

Answer:

  • C. f(x) = 470(0.88)ˣ

Step-by-step explanation:

  • Initial number =  470
  • Decrease rate = 12%   ⇒ 100% - 12% = 88%   ⇒ 0.88 times

<u>Required equation:</u>

  • f(x) = 470(0.88)ˣ

Correct choice is C

One grain of sand approximately weighs 7 * 10^{-5} g. How many grains of sand are there in 6300 kg of sand? Give your answer in
sertanlavr [38]

Answer:

Proportion states that the two ratio or fractions are equal.

Given the statement: One grain of sand approximately weighs 7 * 10^{-5} g.

To find how many grains of sand are there in 6300 kg of sand.

Let x be the number of grains of sand in 6300 kg of sand.

Using conversion :

1 kg = 1000 g

6300 kg = 6300000 g

Then, by using proportion method, we have;

\frac{1}{7\times 10^{-5}}= \frac{x}{6300000}

\frac{10^5}{7} = \frac{x}{6300000}

By cross multiply we get;

6300000 \times 10^5 = 7x

or

63 \times 10^5 \times 10^5 = 7x

63 \times 10^{5+5} = 7x  [using x^a \cdot x^b = x^{a+b}]

63 \times 10^{10} = 7x

Divide both sides by 7 we get;

x = \frac{63 \times 10^{10}}{7} = 9 \times 10^{10}

Standard form is a way of of writing down very large or very small numbers easily.

Therefore, 9 \times 10^{10} grains of sand are there in 6300 kg of sand.

Need help with 5. Part C
Mamont248 [21]

Answer:

  BA = 12

Step-by-step explanation:

All the right triangles are similar, so the ratio of hypotenuse to long side is a constant. In particular ΔABC ~ ΔDBA, so ...

  hypotenuse/long-side = BC/BA = BA/BD

Cross multiplying gives ...

  BA² = BC·BD

  BA = √(BC·BD) = √(16·9)

  BA = 12
