Six times the sum of a number and eight is 30. Find the number

Answers

Answer:

-3

Step-by-step explanation:

to the following equation:

6(x + 8) = 30

Now, we need to solve this equation for x. First, distribute the 6 on the left side of the equation:

6x + 48 = 30

Next, isolate the variable x by subtracting 48 from both sides of the equation:

6x = 30 - 48

6x = -18

Finally, divide both sides by 6 to solve for x:

x = -18 / 6

x = -3

So, the number is -3.

If $396 is invested at an interest rate of 13% per year and is compounded continuously, how much will the investment be worth in 3 years?

Answers

if the interest is compound (yearly) then is calculated by
A = P (1+r)^(t)

then after 3 years the investment will worth

396(1.13)^3 = $571.38

Answer:

$\$584.88$

Step-by-step explanation:

we know that

The formula to calculate continuously compounded interest is equal to

$A=P(e)^(rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

e is the mathematical constant number

we have

$t=3\ years\n P=\$396\n r=0.13$

substitute in the formula above

$A=\$396(e)^(0.13*3)=\$584.88$

there is a bag filled with 3 blue and 4 red marbles. A marble is taken at random from the bag, the colour is noted and then it is not replaced. another marble is taken at random. what is the probability of getting 2 reds ?

Answers

You can just use some sort of counting principle
The first time you draw a read marble, your odds of getting 1 were 4/7
You are not replacing the marble. Your choice now is 3/6

P(2 reds) = (4/7) * (3/7) = 12/49 <<<<< Answer

the probability is:
$(1)/(49)$
1/49

good luck
