The explanation of using Literal equations to solve for a given variable is as explained below.

How to solve Literal Equations?

Literal equations are equations containing two or more variables; at least one independent variable and one dependent variable

To solve a literal equation means to rewrite the equation so a different variable stands alone on one side of the equals sign. We have to be told for which variable we want to solve.

Linear equations in one variable may take the form ax + b = 0  and are solved using basic algebraic operations.

We begin by classifying linear equations in one variable as one of three types: identity, conditional, or inconsistent. An identity equation is true for all values of the variable.

What is the explicit formula for this geometric sequence? 8, 4 2, 1
11Alexandr11 [23.1K]

Answer:

C

Step-by-step explanation:

The standard form for the explicit formula of a geometric sequence is given by:

a_n=a\cdot(r)^{n-1}

Where a is the initial term, r is the common ratio, and n is the nth term.

Our sequence is: 8, 4, 2, 1...

So, we can see that our initial term or a is 8.

Each subsequent term is half of the previous one. So, our common ratio is 1/2.

Let's substitute 8 for a and 1/2 for r to acquire:

a_n=8\cdot(\frac{1}{2})^{n-1}

So, our answer is C.

And we're done!

A jeweler needs 50 ounces of a 21% silver alloy. Find the amount of a 12% silver alloy and the amount of a 24% silver alloy he s
sergij07 [2.7K]

Answer:

  • 12.5 ounces of 12% alloy
  • 37.5 ounces of 24% alloy

Step-by-step explanation:

Let x represent the amount (in ounces) of 24% alloy in the mix. Then the amount of 12% alloy is (50 -x). The amount of silver in the mix is ...

  24%·x + 12%·(50 -x) = 21%·50

  12x = 450 . . . . . . simplify, multiply by 100 (to eliminate %), and subtract 600

  x = 37.5 . . . . . . . divide by 12

The jeweler needs to mix 37.5 ounces of 24% silver alloy with 12.5 ounces of 12% silver alloy to make 50 ounces of 21% silver alloy.

Emilia conducted an experiment with Growing crystals. At the beginning of the experiment, she had a crystal that measured 6MM. S
hammer [34]

Answer: (2,30), (5,66)

Step-by-step explanation: I truly don’t know if this is correct, but at the beginning, the crystal was already 6 mm. She then realized it increased 12 mm every hour, so if one hour passed, it would be 12+6= 18. Okay, so now that we know that, we multiple the hours by 12 and then add the 6.

12x2= 24

24+ 6= 30,

12x5= 60

60+6= 66

A roulette wheel has 37 numbers (0 through 36).
NeX [460]

\large\boxed{\frac{1}{1369}}

We'll assume that there is an equal probability of any position on the wheel, so a \frac{1}{37} chance for any given number.

We must take the probability of getting a 27, then the probability of getting a 15, and multiply them together to find the chances that they both happen in a row.

\frac{1}{37}\cdot\frac{1}{37}=\boxed{\frac{1}{1369}}
