Langkah 2

Suku 1/2 (n + 1)

1/2 (10 + 1) istilah

= 11/2 istilah

= 5,5 suku

Istilah ini antara istilah ke-5 dan ke-6

Suku ke-5 = 12

Suku ke-6 = 12

= 12 + 12/2 = 24/2

= 12

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

Step-by-step explanation:

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:

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.

Answer: A≈63.62

Step-by-step explanation:

9/2= 4.5

A=πr2=π·4.52≈63.61725

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

y = 2(x - 1)² + 4

y = 2(x² - 2x + 1) + 4

y = 2x² - 4x + 2 + 4

y = 2x² - 4x + 6

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.

Answer:

Principal = Rs 2000

Time = 4 years

Interest = Rs 400

Now, Interest= Principal×Rate×Time/100

400= 2000×R×4/100

R= 400×100/2000×4

Answer:

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.

Answer:

39,494 square miles

Step-by-step explanation:

Simple: 49,108-9,614= 39,494 square miles

Answer: Simplifying a square root just means factoring out any perfect squares from the radicand, moving them to the left of the radical symbol, and leaving the other factor inside the radical symbol. If the number is a perfect square, then the radical sign will disappear once you write down its root. hope this helps can u give me brainliest or use this link it can help u

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:

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
