when you reverse the digits in a certain two-diget number you increase it value by 27. What is the number if the sum of its digits is 5

Answers

Answer 1

Answer: The number is = 10x+y
if reverse the digits, the number is: 10y+x
The sum fo its digits is = x+y=5
I suggest this system of equations:
(10y+x)-(10x+y)=27 ⇒9y-9x=27
x+y=5
We can solve this system of equations by equaliztion method
x=5-y

9y-9(5-y)=27
9y-45+9y=27
18y=27+45
18y=72
y=72/18
y=4

x=5-y
x=5-4=1

The number is: 10x+y=10(1)+4=14

Answer: the number is 14

Answer 2

Answer: 14 or 41

41 - 14 = 37

4+1 = 5

Answers

The account which is not the example of the type of savings vehicle is Checking Account. Thus option 3rd is correct.

What are the 3 types of savings?

The three kinds of the saving account are regular deposit, money market, and Certificate of Deposits. There is a difference in all the three types in terms of the accessibility and amount of interest.

The Checking account is the account which carries the day to day transactions of the money. It ensures the easy access to the money. Many of the people generally uses the debit card or the checks to make the purchases. Thus option 3rd is correct.

Rectangle ABCD and right triangle DCE have the same area. They are joined to form a trapezoid, as shown. What is DE?

Answers

Since the areas are the same (5 x 6 = 30 units), and the height of the triangle (DC) is 5 so the length of the triangle must be 12. (1/2 of 5 x 12 is also 30)

So now we use the Pythagorean theorem

a² + b² = c² we have 5² + 12² = c² or 25 + 144 = c² or 169 = c²

The square root of 169 is 13 so side DE is 13 units.

What is the exact area of a circle with a diameter of 25 pi m?A. 25 pi m²

B. 50 pi m²

C.156.25 pi m²

D. 625 pi m²

Answers

The rule to figuring out the area of a circle is A=r^2*pi.

So since the radius is half of the diameter you will ne to cut 25 in half. Which equals 12.5. OK so now we need to multiply 12.5 by 12.5 which equals 156.25.

So i believe that the Answer is C. 156.25pi m^2

Diameter = radius * 2
25 = radius * 2
radius = 12.5

Area = radius^2 * pi
Area = 12.5^2 * pi

Area = 156.25 pi m^2

Your answer is C.

3 times as much as the sum of 3-4 and 2-6.

Further explanation

The Problem:

3 times as much as the sum of $(3)/(4)$ and $(2)/(6)$
Write an expression to match, and then solve.

The Process:

Here are some early expressions that need attention.

three-quarter is $\boxed{(3)/(4)}$
two-sixth is $\boxed{(2)/(6)}$
the sum of $(3)/(4) \ and \ (2)/(6)$ is $\boxed{(3)/(4) + (2)/(6)}$

Let us write an expression to match for3 times as much as the sum of $(3)/(4)$ and $(2)/(6)$

$\boxed{\boxed{ \ 3 * \bigg((3)/(4) + (2)/(6) \bigg) \ }}$

Let us calculate the operation in parentheses at first.

$(3)/(4) + (2)/(6)$

A least common multiple of 4 and 6 is 12. We use to equate the denominator.

$(3 * 3)/(4 * 3) + (2 * 2)/(6 * 2)$

$(9)/(12) + (4)/(12)$

$(13)/(12)$

And now we solve the full expression.

$\boxed{ \ = 3 * \bigg((3)/(4) + (2)/(6) \bigg) \ }$

$\boxed{ \ = 3 * (13)/(12) \ }$

We cross out 3 and 12 because they both can be divided.

$\boxed{ \ = 1 * 1(13)/(4) \ }$

$\boxed{\boxed{ \ = (13)/(4) \ }}$

In mixed fraction:

$\boxed{ \ (13)/(4) = \ ? \ }$

$\boxed{ \ = (12)/(4) + (1)/(4) \ }$

$\boxed{ \ = 3 + (1)/(4) \ }$

$\boxed{\boxed{ \ = 3(1)/(4) \ }}$

In decimal:

$\boxed{ \ 3(1)/(4) = \ ? \ }$

$\boxed{ \ = 3(1 * 25)/(4 * 25) \ }$

$\boxed{ \ = 3(25)/(100) \ }$

$\boxed{\boxed{ \ = 3.25 \ }}$

$\boxed{\boxed{ \ Thus, \ the \ result \ is \ (13)/(4) \ or \ 3(1)/(4) \ or \ 3.25 \ }}$

Quick Steps:

Simplify $\boxed{(2)/(6) = (1)/(3)}$

$\boxed{ \ = 3 * \bigg((3)/(4) + (2)/(6) \bigg) \ }$

$\boxed{ \ = 3 * \bigg((3)/(4) + (1)/(3) \bigg) \ }$

$\boxed{ \ = 3 * \bigg((3 * 3)/(4 * 3) + (1 * 4)/(3 * 4) \bigg) \ }$

$\boxed{ \ = 3 * \bigg((9)/(12) + (4)/(12) \bigg) \ }$

$\boxed{ \ = 3 * (13)/(12) \ }$

$\boxed{\boxed{ \ = (13)/(4) \ }}$

$\boxed{\boxed{ \ = 3(1)/(4) \ }}$

$\boxed{\boxed{ \ = 3.25 \ }}$
