Answer:

Mr. and Mrs. Jones retirement income will be $32,000

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

According to the question the couples last pre-retirement earnings were $47,000. Since they plan on retiring with 70% percent of their pre-retirement earnings, this means we need to multiply their pre-earnings by 70% in decimal form.

So, the first thing we need to do is turn 70% into a decimal by moving the decimal two digits to the left.

70.0%   ⇔   0.70

Now we multiply 0.70 by $47,000 to find their retirement income.

r = 47,000 * 0.70

r = 32,900

Finally, we can see that Mr. and Mrs. Jones retirement income will be $32,000

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Sue has a balance of $35in her checking account. She writes one of the check for$10,and three checks for $9 each what is her balance now

Answers

We have to subtract the total of the written checks from the total money in her balance; so first lets add the total of the checks:
$10 + $9 + $9 + $9 = $37.00
Now that we found the total money of checks we must now subtract it from the balance:
$35 - $37 = -$2.00
So her ending balance is -$2.00

Suppose we want to choose 2 objects without replacement from the 4 colors red, blue, green, purple. How many ways can this be done, if the order of the choices matter?

Answers

Answer:

Number of ways = 6

Step-by-step explanation:

Given:

Total number of choices = 4

Taken object choices = 2

Find:

Number of ways

Computation:

Number of ways =  [4 × 3] / 2!

Number of ways = [4 × 3] / [2 × 1]

Number of ways = [12] / [2]

Number of ways = 6

The end points of one side of a regular pentagon are (-1,4) and (2,3). What is the perimeter of the pentagon?(1) the square root of 10
(2) 5 times the square root of 10
(3) 5 times the square root of 2
(4) 25 times the square root of 2

Answers

To determine the perimeter of the pentagon, you must first calculate a side length of it. Let's name the coordinates A(-1,4) and B(2,3).

To figure out how far the points are from each other, you have to use the distance formula:
D_(AB) = \sqrt{( x_(2)-x_(1))^2+{(y_(2)-y_(1))^2}
x_(1) =1, x_(2) =-2, y_(1) =2, y_(2) =3
D_(AB)= \sqrt{(2--1)^2+{(3-4)^2}
D_{AB}= \sqrt{(2--1)^2+{(3-4)^2} 
D_(AB)= \sqrt{(2+1)^2+{(3-4)^2}
D_(AB)= √((3)^2+(-1)^2)
D_(AB)= √(9+1)
D_(AB)= √(10)

Now, the formula for the perimeter of a pentagon is 
P = 5×side length
 
So...
Perimeter = 5×√(10)

The answer is (2)

the answer is (2) because using the distance formula which can be found on your browser, it will lead us to the answer 5 radical 10
