Step-by-step explanation:

Given in the question,

radius of a plate = 3 inches

π  = 3.14

To find,

circumference of the plate.

As we know that formula to calculate circumference of a circle given radius

<h2>2 π r</h2>

2 (π) (3)

2 (3.14) (3)

How much must be deposited today into the following account in order to have $35,000 in 7 years for a down payment on a​ house?
Rom4ik [11]

Answer:

The amount that must be deposited is $ 19973.87.

Step-by-step explanation:

We have a relation between future value present value as:

                                       F= P (1 +\frac{r}{n}  )^{nt}

F=future value

P=present value

r=rate (as a decimal)

n=number of compounding periods per year

t=number of years

Now,

               assume rate as 8%

                                       35000= P (1+\frac{0.08}{12} )^{12*7}

                                or,   35000= P × 1.0067^{84}

                                      or, P = \frac{35000}{1.7522}

                                     or, P = $ 19973.87

So you must deposit $ 19973.87 today.

If 11 - 3x = x, then 20x=
dimaraw [331]

Answer:

20x = 55

Step-by-step explanation:

First you have to add 3x to both sides of 11-3x=x

11-3x=x\\+3x=+3x\\11=4x

Now that you have 11 = 4x you divide 4 on both sides \frac{11}{4} =\frac{4x}{4}

11/4 = x

But you can't divide 11 by 4 unless you are looking for the decimal form of 11/4 which is 2.75

so now we take 11/4 or 2.75 depending on if you need your answer in fraction or as a decimal and replace that with x  however both will equal the number 55

20(\frac{11}{4})=55\\20(2.75)=55
