r=-6/1=-6

[tex]S_{7}=a\frac{1-r^n}{1-r} =1\frac{1-(-6)^7}{1-(-6)} \\=\frac{1+6^7}{1+6} \\=\frac{1+279936}{7} \\=\frac{279937}{7} \\=39991[/tex]

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:

60 were left with Ken, and that is 75%

Step-by-step explanation:

80-10 = 70

70-10 = 60

60/80 = x/100, simplify & cross multiply

6/8 = x/100

600 = 8x

x = 75

Given:

A coordinate pair was dilated from (-3, 2) to (-6, 4).

To find:

The scale factor.

Solution:

We need to divide the coordinate of dilated point by the corresponding coordinate of original point to find the scale factor.

The value of scale factor is:

[tex]k=\dfrac{x\text{-coordinate of image}}{x\text{-coordinate of original point}}[/tex]

[tex]k=\dfrac{-6}{-3}[/tex]

[tex]k=2[/tex]

Therefore, the scale factor is 2.

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:

When x=2

Step-by-step explanation:

Well in the first one it tells you that 2x is 90.

In the second it's y=40x+10

So you plug 2 in as the x.

y=40(2)+10

y=80+10

y=90

Answer:

Step-by-step explanation:

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

Step-by-step explanation:

y = 2(x - 1)² + 4

y = 2(x² - 2x + 1) + 4

y = 2x² - 4x + 2 + 4

y = 2x² - 4x + 6

Answer:

1) 4 hours  2) 144 miles  3) 12 miles

Step-by-step explanation:

60/5=12

72/6=12

120/10=12

180/15= 12

1) 48 miles / 12 miles = 4 hours

2) 12 hours x 12 miles = 144 miles

3) 1 hour x 12 miles = 12 miles

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.

Step-by-step explanation:

Median data dihitung sebagai

= 1/2 (n + 1) suku ke-1

Dimana n = Jumlah suku

= 10

Langkah 1

Kami mengatur ulang

8, 9, 10, 10, 12, 12, 13, 15, 15, 17

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

Median data adalah 12

Answer:  -10; -2; 0

Step-by-step explanation:

≥ means greater or equal than.

-10 is equal -10, true.

-14 is less than -10, so false.

-2 is greater than -10, true

0 is greater than -10, true

so the answer is -10, -2 and 0 can make this inequality true.

Answer:

Step-by-step explanation:

552,200 people × (1 km²)/6,300 people) ≈ 87.65 km²

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:

x= 11.4

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
