What is the approximate area of a circle with the diameter of 20cm in square centimeters (use 3.14 for pie(

Answers

Answer:

314cm

Step-by-step explanation:

the area formular for a circle is a=pi(r)^2. Using this information we can plug in the numbers...

3.14(10)^2. Next square 10 to get 3.14*100. Then you get 314 which is the answer. The reason I used 10 is because the diameter is half of the radius so half of 20 would be 10.

What is meant by Parallel lines?Parallel lines are two lines in the same plane that are equal distance apart and never intersect. Real-world parallel line examples include railroad tracks, sidewalk edges, street markings, zebra crossings, the surface of pineapple and strawberry fruit, staircases and railings, and so on.Parallel lines are lines in a plane that never meet, no matter how far they are extended. The distance between the parallel lines is constant because they never meet. Parallel lines are defined as lines that do not intersect or meet at any point in a plane. They are always parallel and equidistant from one another.

Step-by-step explanation:

fist find how much of 6750 is 6.25%

6750 * .0625 = 421.875

then use trial and error until u get the number u want

421.875 * 10 = 4218.75 + 6750 = 1096875 NO

421.875 * 20 = 84375 + 6750 = 151875 NO

421.875 * 30 = 12656.25 + 6750 = 19406.25 NO

421.875 * 31 = 13078.125 + 6750 = 19828.125 NO

a = 4, b = -7, c = -15

a x c = -60

Your answer is A!

Step-by-step explanation:

Your answer is A!

The coordinate point from the given graph is (3, -5). Therefore, option A is the correct answer.

What is coordinate plane?

A coordinate plane is a two-dimensional surface formed by two number lines. It is formed when a horizontal line (the X-axis) and a vertical line (the Y-axis) intersect at a point called the origin. The numbers on a coordinate grid are used to locate points.

From the given coordinate plane, the coordinate point lies in fourth quadrant.

Where, x-coordinate is positive and y-coordinate is is negative.

The coordinate point correspond to x-axis is 3 and coordinate point correspond to y-axis is 5.

So, the coordinate point is (3, -5)

Therefore, option A is the correct answer.

A new business borrows $320,000 at a yearly simple interest rate of 7%. The total amount the
company repays for the loan and interest is $678,400. How long did it take to pay off the loan?

Answers

Answer:

16 years

Step-by-step explanation:

Annual interest payment is 7% * 320k = 22,400

Total interest is 678400-320000=358400

358400/22400=16

The number of years that it takes to pay off the loan will be 16 years.

What is simple interest?

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

The formula for interest is written as,

I = (PRT)/100

Where P is the principal, R is the rate of interest, and T is the time.

A new business borrows $320,000 at a yearly simple interest rate of 7%. The total amount the company repays for the loan and interest is $678,400. Then the equation is given as,

P + I = A

$320,000 + ($320,000 x 7 x T) / 100 = $678,400

$22,400 T = $358,400

T = 16 years

The number of years that it takes to pay off the loan will be 16 years.

child was $5.66. There were two adults in the group. The families intend to spend no more than
$46.00. What is the greatest number of child tickets that can be purchased?

Answers

Answer:

5 children

Step-by-step explanation:

$7.31 x2 = $14.62

$46- 14.62 =$32

5.66 divided by 5 = 28.3

5.66 divided by 6 = 33

and $33 is bigger than $31

So the greatest number of children tickets can be purchased is only 5.

Answer:

5 children

Step-by-step explanation:

Solve

$7.31 x2 = $14.62

$46 - 14.62 =$32

5.66 divided by 5 = 28.3

5.66 divided by 6 = 33

$33 is bigger than $31

Therefore, the greatest number of children tickets can be purchased is only 5.

A right angled triangular prism has length 3m, breadth 2m and height 2.5m. If the mass of the prism is 3.4kg, find its density​

Answers

Answer:

The density of the prism is 0.453 kilograms per cubic meter.

Step-by-step explanation:

Let suppose that mass in the prism is uniformly distributed. Then, the definition of density ([tex]\rho[/tex]), in kilograms per cubic meter, is defined by the equation below:

[tex]\rho = \frac{m}{V}[/tex] (1)

Where:

[tex]m[/tex] - Mass, in kilograms.

[tex]V[/tex] - Volume of the right angle triangle prism, in cubic meters.

Besides, the volume of the right angle triangle prism is:

[tex]V = \frac{1}{2}\cdot b\cdot h\cdot l[/tex] (2)

Where:

[tex]b[/tex] - Breadth of the base, in meters.

[tex]h[/tex] - Height of the base, in meters.

[tex]l[/tex] - Length of the base, in meters.

If we know that [tex]b = 2\,m[/tex], [tex]h = 2.5\,m[/tex], [tex]l = 3\,m[/tex] and [tex]m = 3.4\,kg[/tex], then the density of the prism is:

[tex]V = 7.5\,m^{3}[/tex]

[tex]\rho = 0.453\,\frac{kg}{m^{3}}[/tex]

The density of the prism is 0.453 kilograms per cubic meter.

Answers

Answer:

7.900 cm

Step-by-step explanation:

The computation of the diameter after using the tape is given below:

Since the circumference is 14.8 cm

And it would be decrease by 2.4 cm

So, the new circumference is

= 14.8 - 2.4

= 12.4 cm

Now the radius is

= 12.4 ÷ π

= 3.95

And, the diameter is

= 3.95 × 2

= 7.900 cm

Then to find how many tutors you need for 81 students you would need 4 tutors because you want to divide 81 by the unit rate we got (22), and since the answer would be a decimal (3.68.....) you would need to round the whole number up to four because you cant have a decimal of a person.
