Answer:

To find the area of a circle we have [tex]\pir^{2}[/tex] and the radius is half of the diameter so we have 4.5² which gives 16.25π

When interest compounded continuously so the amount after 10 years the amount will be $18819.75, when n = 365 and t = 10 years amount will be $18819.22, when n = 12 and t = 10 years amount will be $18803.91.

It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.

We can calculate the compound interest using the below formula:

[tex]A = P (1 + \frac{r}{n} )^{nt}[/tex]

Where A = Final amount

         P = Principal amount

         r  = annual rate of interest

         n = how many times interest is compounded per year

         t = How long the money is deposited or borrowed (in years)

If the interest compounded continuously:

P = $12000, r = 4.5% = 0.045%

⇒ [tex]A (t) = 12000 (e)^{0.045t}[/tex]

When t = 10 years, plug this value in the above expression and calculating, we get;

A(10) = $18819.75

When interest compounded daily:

[tex]A(t) = 12000 (1 + \frac{0.045}{365} )^{365t}[/tex]

Plug t = 10 years:

We get;

A(10) = $18819.22

Similarly, If interest is compounded monthly:

n = 12 and t =10, we get:

A(10) = $18803.91

Thus, when interest compounded continuously so the amount after 10 years the amount will be $18819.75, when n = 365 and t = 10 years amount will be $18819.22, when n = 12 and t = 10 years amount will be $18803.91.

Answer:  -8, -5, -2, 1, 4

Step-by-step explanation:

Y=3x-2

- Plug in the number for x.

x = -2, y = 3x - 2= 3(-2) - 2 = - 6 - 2= - 8

x = -1, y = 3x - 2= 3(-1) - 2 = - 3 - 2= - 5

x = 0, y = 3x - 2= 3(0) - 2 = 0- 2= - 2

x = 1, y = 3x - 2= 3(1) - 2 = 3 - 2= 1

x = 2, y = 3x - 2= 3(2) - 2 = 6 - 2= 4

Answer:

First, we know that he spent rs500 plus rs60 in the whole process, then the total cost is:

C = rs500 + rs60 = rs560

Now he sells the oranges in packs of 12, then if he has 120 oranges, the total number of packs that he can sell is:

120/12 = 10

So he has 10 packs of 12 oranges.

And he sells each one for rs58.8

Then if he sells the 10 packs, the total revenue is:

R = 10*(rs58.8) = rs588

The profit is the difference between the revenue and the cost, here the profit is:

P = R - C = rs588 - rs560 = rs28

And the profit percentage is calculated as follows:

(P/C)*100%

Where P = profit and C = cost, then we have:

(rs28/rs560)*100% = 5%

Answer:

the plane flies 396,000yd in 30 min

Step-by-step explanation:

450 / 2 = 225

1 mile = 1,760

225 * 1,760 = 396,000 yd

Plz mark as brainliest if this helped! Have a nice day!!!

-Lil_G

Step-by-step explanation:

450 miles = 1hour = 60mins

X miles = 30mins

cross multiply

450 × 30 = 60 × X

13500 = 60X

divide through by 60

225 = X

therefore, X = 225miles

now

1 mile= 1760 yards

225 miles = X

cross multiply

X = 1760 ×225

X = 396000 yards

The product of the rational expression 2/x(3/2 x-5) is 3-10/x.

Expression is combination of numbers, fraction, symbols , coefficients, indeterminants or determinants. It shows a relationship between variables. It is mostly not found in equal to form.

We have been given an expression 2/x(3/2 x-5) and we have to find the product of the expressions.

Product=2/x*3/2 x-2/x*5

To find the product of the expression, we have to multiply numerators with numerators and denominators with denominators and then perform the division part.

=6x/2x-10/x

=3-10/x

Hence the product of the rational expression 2/x(3/2 x-5) is 3-10/x.

Answer:

y = 121.14

Step-by-step explanation:

For this, we will need to start by cross multiplying.

(4.2 * y) = (48 * 10.6)

4.2y = 508.8

to isolate the varible, we need to divide both sides by 4.2

y = 121.14

Answer:

Table 2: 1 Chair

Cupboard 5: 1 Table

Cupboard 10: 1 Chair

The table costs 4,000 rupees, the chair 2,000 rupees, and the cupboard costs 20,000 rupees.

Step-by-step explanation:

Since the cost of a table is double the cost of a chair and the cost of a cupboard is five times the cost of a table, to determine what is the ratio of the cost of the chair, the table and the cupboard the following calculations must be done:

Table 2: 1 Chair

Cupboard 5: 1 Table

5x2 = 10

Cupboard 10: 1 Chair

In turn, if the cost of a table is greater than that of a chair by 2000 rupees, to find the cost of a chair, table and the cupboard, the following calculations must be performed:

Table 2: 1 Chair

2000 x 2 = 4,000

Thus, the table costs 4,000 rupees and the chair 2,000 rupees.

4000 x 5 = 20,000

In turn, the cupboard costs 20,000 rupees.

Step-by-step explanation:

for the base of the triangles BC is 15 and DF is 5 so if 5 times 3 is 15 then you are reducing the other triangle to a third of the big triangles size. so 3.8 times three is 11 4

Answer:

Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene, isosceles, equilateral and so on.

The triangle inequality property states that the sum of any two sides of a triangle must be greater than the third side. If a, b and c are the sides of a triangle then:

a + b > c;   a + c > b;   b + c > a

Given a triangle with side length 4 m, 8 m, 9 m:

4m + 8m = 12m > 9m

4m + 9m = 13m > 8m

8m + 9m = 17m > 4m

Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m.

Step-by-step explanation:

The Egyptians calculated the area of a circle by a formula that gave the approximate value of 3.1605 for π. The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.

Answer:

π is a mathematical constant. Its commonly used value is 3.14. There is a expanded value for π. It appears in many formulas in all areas of mathematics and physics. In maths, it is commonly used for solving of circles and spheres.

The π was invented by Archimedes of Syracuse. He was one of the greatest mathematicians of the ancient world.

It's just 5 * 4 which is 20.

Given:

The central angle = [tex]\theta[/tex]

Radius of the circle = 4 ft

Intercepted arc length = 50ft

To find:

The value of [tex]\theta [/tex] in radian measure.

Solution:

The formula for arc length is

[tex]s=r\theta[/tex]

where, r is radius and [tex]\theta [/tex] is the central angle in radians.

Putting s=50 and r=4, we get

[tex]50=4\theta[/tex]

Divide both sides by 4.

[tex]\dfrac{50}{4}=\theta[/tex]

[tex]12.5=\theta[/tex]

Therefore, the value of [tex]\theta [/tex] is 12.5 radians.
