Step-by-step explanation:

Condition for a triangle formed by three segments,

Sum of two segments should be greater than third segment

1). AC + BC > AB

2). AC + AB > BC

3). AB + BC > AC

1). AC + BC > AB

   1 + 8 > 8

   9 > 8

   Triangle is possible.

2). AC + AB > BC

   1 + 8 > 8

   9 > 8

   Triangle is possible.

3). AB + BC > AC

    8 + 8 > 1

    16 > 1

   Triangle is possible.

Therefore, with the help of given segments triangle can be formed.

Answer:

if you do the problem 5 and 11 with that multiply and but dont forgoet to divide that number its B

Answer:

x=4,−2

Step-by-step explanation:

Because Step 1. Move all terms to one side.

{x}^{2}-2x-8=0

x

2

−2x−8=0

2 Factor {x}^{2}-2x-8x

2

−2x−8.

1 Ask: Which two numbers add up to -2−2 and multiply to -8−8?

-4−4 and 22

Step 2. Rewrite the expression using the above.

(x-4)(x+2)

(x−4)(x+2)

and going to;

(x-4)(x+2)=0

(x−4)(x+2)=0

And Step 3. Solve for xx.

1 Ask: When will (x-4)(x+2)(x−4)(x+2) equal zero?

When x-4=0x−4=0 or x+2=0x+2=0

2 Solve each of the 2 equations above.

x=4,-2

x=4,−2

x=4,-2

Our Answer is:

x=4,−2

Answer:

I'll setup the problem and you can do the calculations

Step-by-step explanation:

a.

[tex]V = \pi( {D}^{2} \div 4)H[/tex]

V = volume; D = diameter; H = height of can

b.

Area of the Tin is the total area of the 2 Tin circles

one circle's area A is

[tex]A = \pi {D}^{2} \div 4[/tex]

A = area; D = diameter

calculate A

Then multiply by 2

c.

The area of the cardboard is the circumstance of the circle

times the height

[tex]SA = \pi DH[/tex]

d.

add answers from b and c

Answer:

494018

Step-by-step explanation:

you are trying to find the diameter of the circle, it is usually half the length of a radius, but since 497 squared is how long a radius is (unless the question asked that the area if 497 inches squared), i can't really give you a clear answer, but the diameter is 247009 times 2 which is 494018

Answer:

Demas gastos= $492.000

Step-by-step explanation:

Dada la siguiente información:

Una persona que gana $2460000, invierte 35% en arriendo, 20% en alimentación, 25% en diversión y el resto para los demás gastos.

Primero, debemos determinar cuanto gasta en cada item:

Arriendo= 2.460.000*0,35=861.000

Alimentación= 2.460.000*0,20=492.000

Diversión= 2.460.000*0,25= 615.000

Total= $1.968.000

Ahora, lo que gasta en "demás gastos":

Demas gastos= 2.460.000 - 1.968.000

Demas gastos= $492.000

Step-by-step explanation:

The x-intercept is at (-3, 0). To find the slope of the perpendicular line, let's rewrite the equation to its slope-intercept form, which is

y = (2/3)x + 2

This means that the perpendicular line has a slope m = -3/2. So the slope-intercept form of this new line is

y = -(3/2)x + k. Since this line passes through (-3, 0), we cal solve for k:

0 = -(3/2)(-3) + k or k = -9/2

So our equation becomes (slope-intercept form)

[tex]y = - \frac{3}{2}x - \frac{9}{2} [/tex]

or in its standard form,

[tex]3x + 2y + 9 = 0[/tex]

Answer: G

Step-by-step explanation:

Data: Point which has the coordinates of (-2.5, 5.5)=x

Only step, find those two coordinates on the table

Explanation: Since the question is asking you to find  which point has those two coordinates, all you have to do is instead of finding all the coordinates of the points, just search for the coordinates provided and see what point it lands on.

For this problem, it lands on Point G so the answer is Point G(or just G)

Answer: The number of people can be expected to have cold = 34

Step-by-step explanation:

Given: The ratio of people who actually have the flu to the people who have flu-like symptoms is 1:6.

If a doctor sees 40 patients, then the number of people can be expected to have cold = [tex]40\times\dfrac{6}{1+6}[/tex]

[tex]=40\times\dfrac6{7}[/tex]

[tex]=\dfrac{240}{7}\\\\=34.29\approx34[/tex]

Hence, the number of people can be expected to have cold = 34

Answer:

$5.20

Step-by-step explanation:

A dozen is 12, so multiply by two.

2.60 * 2 = $5.20

Answer:

5.20 for 12

2.60 for 6

2.60*2=12

5.20 for 12

Answer:

$45

Step-by-step explanation:

If it looses it value of 14 % every year, by the end of 5 years, the value would go down by 70%.  So, 150x0.7= 105, 150-105=45, so it would be. worth. 45% in 5 years.

Answer:

Option (3)

Step-by-step explanation:

Since, flowerbed is in the shape of a right triangle,

By applying Pythagoras theorem in the given right triangle,

(Hypotenuse)² = (leg 1)² + (leg 2)²

(Hypotenuse)² = (12)² + (12)²

(Hypotenuse)² = 144 + 144

Hypotenuse = √288

Hypotenuse = 16.97

                     ≈ 17 ft

Perimeter of the triangle = Sum of the measures of three sides of the triangle

= 12 + 12 + 17

= 41 ft

Therefore, Option (3) will be the correct option.

Answer:

41ft

I think this the answer

Step-by-step explanation:

The Thousand Bolts factory has an order for 3,140 bolts. How can it pack the order using the fewest packages?

Answer:

Because X (10) repeats

Step-by-step explanation:

A function has no repeated X but here in your x variable 10 is there twice so therefore it is NOT a function

You can use the pencil test also in a graph, align your pencil vertically and see if there are multiple points that have the same X and if there isn't any repeated its a function.

Answer:

The function is a relation between two sets that associates to each element of the first set exactly one element of the second set.

We have x = 10 twice with different f(x) associated, 5 and 20.

If we plot those points they will be on same vertical line, thus the vertical line test is failed.
