Answer 1

Answer:
4.2% means 0.042 .

4.2% more than some amount is 1.042 of it.

Interest compounded annually means that a year after you deposit some money
into your bank account, the bank looks to see how much of your money has been
there for a year, and they add 4.2% of that into your account. Another way to
look at it is that they change the balance in your account, from the amount it was
a year ago, to 1.042 of that amount. That's right. They just give you free money !

Why that's so good is: Now the new amount in your account is 1.042 of
the amount you originally deposited, and after another year, they'll give you
another 4.2% of that larger amount. Then you'll have (1.042)² = about
8.6% more than your original deposit, 2 years earlier.

At the end of any number of years ... call it 't' years ... the amount in your
account is the amount you deposited, multiplied by (1.042)^'t' power.

If you just put some money into this particular bank, and forget about it
and never touch it, you'll have double the amount in 17 years.

Now we can go and take care of Rhonda.

She put $3000 into a new account at the the bank, and then she forgot
about it and never touched it. How much is in that account after 't' years ?
The amount that's in that account at any time is called the 'balance'.
How much is it after 't' years ?

Balance = 3,000 (1.042)^'t' power .

A die is rolled 260 times. Predict how many times it will show a 3 or 5.

Answers

The chances of getting 3 or 5 by 260 times will be 87.

What is probability?

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favorable outcomes / Number of sample

Given that a die is rolled 260 times. The number of times it will show a 3 or 5 will be calculated as below:-

Sample = 6

Number of getting 3 = 1

Number of getting 5 = 1

Probability of getting 3 = 1 / 6

Probability of getting 5 = 1 / 6

Probability of 3 or 5 = ( 1 / 6 ) + ( 1 / 6 )

Probability of 3 or 5 = 2 / 6

Number of times of getting 3 or 5 = ( 2 / 6 ) x 260

Number of times getting 3 or 5 = 87

Therefore, the chances of getting 3 or 5 by 260 times will be 87.

3. Irvin cut a 47 in. wire into two pieces. The longer piece is 13 in. longer than the shorter piece. What is the length of the longer piece?_________ in.

Please Help!!!

Answers

Let's say x to the shoter piece's length, since the longer one is 13 in longer, it's length has to be x+13 in. We know the sum of these pieces is equal to 47. So let's solve:
$x+x+13=47\n 2x+13=47\n 2x=47-13\n 2x=34\n x=\frac { 34 }{ 2 } \n x=17$
the shorter piece's length 'x' is 17 , so the longer piece's length 'x+13' is : $x+13\n 17+13=30$

Step-by-step explanation:

Which shows the equation c=a(w/150) correctly solved for the variable w ?

Answers

$c=a( (w)/(150) )$

$c=a* (w)/(150)$ $Simplify \ brackets$

$c= (aw)/(150)$

$c*150=aw$ $Multiply \ both \ sides \ by \ 150$

$150c=aw$    $Regroup \ terms$

$(150c)/(a) = w$    $Divide \ both \ sides \ by \ a$

$w= (150c)/(a)$    $Solution$

Final answer:

To solve the equation c = a(w/150) for 'w', divide the equation by 'a' and then multiply by 150. This gives us w = 150c/a. This equation represents 'w' in terms of 'c' and 'a'.

Explanation:

To solve the equation c = a(w/150) for the variable w, you need to isolate w on one side of the equation. The goal is to express w in terms of c and a.
