The exchange rate in some prehistoric village was 6 jagged rocks for every 2 smooth pebbles. Also, one shiny rock could be trade

Scrat [10]

30 Jagged rocks are the same 3 shiny rocks using the exchange rates provided(i.e. option D)

What is an exchange rate?

Exchange rate means the rate at which one item exchanges hands with another, for instance, in this case, 6 jagged rocks are equivalent to 2 smooth pebbles.

6 jagged rocks=2 smooth pebbles

divide both sides by 2

6/2 jagged rocks=2/2 smooth pebbles

3 jagged rocks=1 smooth pebble

We can rewrite as below:

1 jagged rock=1/3 smooth pebble

30jagged rocks=1/3*30 smooth pebbles

30 jagged rocks=10 smooth pebbles

Now we need to convert 10 smooth pebbles to shiny rock equivalence

3 smooth pebbles=1 shiny rock

1 smooth pebble=1/3 shiny rock

10 smooth pebbles=1/3*10 shiny rocks

10 smooth pebbles=3 shiny rocks( even though it is 3.33, but the final answer should be rounded to a whole number)

1 What is the equation of the line parallel to 8x - 16y= -14 and passing through (3, 0)?

andreev551 [17]

Answer:

8x -16y = 24

Step-by-step explanation:

8x - 16y= -14

A parallel line (i.e. same slope) will be: 8x - 16y= c

We have to find the value of "c".

If it passes through (x, y) = (3, 0) ⇒ 24 - 0 = c,

so equation is 8x -16y = 24

13. What is the result of adding 5.4a + 7.1 and -1.28 - 6.3?

den301095 [7]

Answer:

C. 4.2a + 0.8

Step-by-step explanation:

Given:

The two binomials given for addition are:

$5.4a+7.1$ and $-1.2a-6.3$

Now, adding both the binomials, we get:

$5.4a+7.1+(-1.2a-6.3)$

Distributing the positive sign inside the second binomial, we get:

$5.4a+7.1-1.2a-6.3$

Now, combining like terms using the commutative property of addition, we get:

$(5.4a-1.2a)+(7.1-6.3)$

Simplifying the above expression, we get:

$(5.4-1.2)a+0.8\\4.2a+0.8$

Therefore, the resulting addition of the given binomials is $4.2a+0.8$

Hence, option C is the correct answer.

Find the complex conjugate of the given number -1+4i

adell [148]

With every imaginary term, there are 2 complex conjugates with opposing signs. So if I had the term a+bi, the complex conjugate would be a-bi. So given your example of -1+4i, the complex conjugate would just be the opposite sign, now negative, to get -1-4i.
