2/4+3/8. how do I calculate this
solniwko [45]
Well, 2/4 is equivalent to 4/8. So you can turn the 2/4 into 4/8 and then add 4/8 plus 3/8.

Answere the question
boyakko [2]

Answer:

no the sign should say 12 percent of people voted darnells

Step-by-step explanation:

because if the population is 10 thousand and you take 25 percent that will put the total amount of people who can vote at 7500 and then take 20 percwnt of that and it will put you at 1500 people who can vote and then if you take 80 percent of 1500 people who can vote than only 1200 of them voted for Darnell which would make it only 12 percent of people voted for darnells

Consider this equation. 7.8+2(0.75m+0.4)=-6.4m+4(0.5m-0.8) Mia solved the equation and determined that m=2. Is she correct?
IgorC [24]

Answer:

B) She is incorrect because when substituting 2 for m the result was a false statement.

Step-by-step explanation:

Let's solve it for ourselves and see if Mia is correct:

7.8+2(0.75m+0.4)=-6.4m+4(0.5m-0.8)

7.8+1.5m+0.8=-6.4m+2m-3.2

1.5m+8.6=-4.4m-3.2

8.6=-5.9m-3.2

11.8=-5.9m

-2=m

m=-2

Since the answer is actually m=-2, Mia's guess is incorrect because plugging in m=2 does not make both sides equal. Therefore B is the correct option.

Compute the missing data in the table for the following exponential function f(x)=(3)^x
slega [8]
ANSWER

The correct answer is B.

27


EXPLANATION

The give function is
f(x) =  {3}^{x}


The missing data occurs at
x = 3

We substitute
x = 3
into the given function and simplify.


This implies that,
f(3) =  {3}^{3}


This gives us,

f(3) =  3 \times 3 \times 3


This simplifies to,

f(3) =  27
Therefore the missing data is 27
