Step-by-step explanation:

Answer:

2 cm, 9 cm, 10 cm

Step-by-step explanation:

To know if a combination is a triangle all you have to do is see if the combinations add up to 180

(2)(9)(10)=180 therefore it is a triangle.

All the other angles do not add up to 180 so they can't be triangles!!

(4)(10)(3) =120

(5)(6)(11) =330

(4)(5)(7) =140

Answer:boy

Step-by-step explanation:boy

Mr. Smith exercises for between 10 and 40 minutes on 77.45 percent of the days in a year.

Given that his exercising time follows a normal distribution with a mean of 30 minutes and a standard deviation of 10 minutes.

Here we have to find the percentage of days in a year that Mr. Smith exercises for between 10 and 40 minutes,

First, we need to standardize the values of 10 and 40 minutes using the formula,

⇒ z = (x - μ) / σ

where x is the value we want to standardize,

μ is the mean,

And σ is the standard deviation.

For x = 10:

⇒ z = (10 - 30) / 10

       = -2

For x = 40:

⇒ z = (40 - 30) / 10

      = 1

Now, we need to find the probability of Mr. Smith exercising between -2 and 1 standard deviations from the mean.

We can use a standard normal distribution table or a calculator to find this probability.

Using a standard normal distribution table,

we can find the probability of z being between -2 and 1 is about 0.7745. This means that on approximately 77.45% of the days in a year, Mr. Smith exercises for between 10 and 40 minutes.

Therefore,

Mr. Smith exercises for between 10 and 40 minutes on approximately 77.45% of the days in a year.

f = v + at

f - v = at

(f-v)/t = a

Answer:

(f - v) / t = a

Step-by-step explanation:

Solving for the equation for a means taking all integers or values on the other side of the equation for a

To do this we must do it mathematically.

f = v + at

f - v = at

Answer:

0.512 ; - 0.538

Step-by-step explanation:

Using the standard linear regression relation :

y = bx + c

b slope ; c = intercept ; y = dependent ; x = independent variable.

For finalist between 2004 - 2014 ;

y = 0.024x - 0.328

x = 35

y = 0.024(35) - 0.328

y = 0.512

For finalist between 1990 - 2014 ; with 14 winners ; change in daily circulation :

y = -0.015x - 0.328

x = 14.

y = -0.015(14) - 0.328

y = - 0.538

Answer:

a) Lateral area of the solid = 2011.43 [tex]cm^{2}[/tex]

b) Surface area of the solid = 2544 [tex]cm^{2}[/tex]

Step-by-step explanation:

a) Lateral area of the figure = 2[tex]\pi[/tex]rh

where; r is the radius of the cylinder, and h is its height.

Lateral area of the figure = 2 x [tex]\frac{22}{7}[/tex] x 10 x 32

                                          = 2011.43 [tex]cm^{2}[/tex]

b) The surface area = 2[tex]\pi[/tex]r(r + h) - 2([tex]\frac{1}{2}[/tex] x b x h)

                                 = 2[tex]\pi[/tex]r(r + h) - (b x h)

The height of the isosceles triangle can be determined by applying the Pythagoras theorem to have,

[tex]10^{2}[/tex] = [tex]6^{2}[/tex] + [tex]h^{2}[/tex]

100 = 36 + [tex]h^{2}[/tex]

[tex]h^{2}[/tex] = 100 - 36

   = 64

h = [tex]\sqrt{64}[/tex]

  = 8

h = 8 cm

The surface area of the solid = 2 x [tex]\frac{22}{7}[/tex] x 10 (10 + 32) - 12 x 8

                                                = 2640 - 96

                                                = 2544

The surface area of the solid is 2544 [tex]cm^{2}[/tex].

2.collect the like terms 3x+8x=11x

3. Then final answer is 11x+3.

Answer:

11x + 3 is the simplest form

Step-by-step explanation:

1/4 (12x + 12) + 8x

First distribute the 1/4 to both terms in the parentheses

= 3x + 3 + 8x

then combine like terms

= 11x + 3

We can't solve for x, only simplify this equation.

Answer:

80

Step-by-step explanation:

Let servings be s and the bag be b

s = 1/8 b

multiply both sides by 8

8s = b

For 10 bags, it will be 10*8s = 80s which is 80 servings.

Answer:

Step-by-step explanation:

W = 2L + 3, and:

P = 2W + 2L = 192

Substituting 2L + 3 for W, we get:

P = 2(2L + 3) + 2L = 192, or

4L + 6 + 2L = 192, or:

6L = 186

L = 186/6 = 31

The length is 31, the width is 62 + 3, or 65

Therefore, the perimeter P is P = 2(31) + 2(65) = 130 + 62  = 192 (OK!)

ASK A RABBIT

Step-by-step explanation:

Answer:

y = 0.2(0.5)^x

Step-by-step explanation:

Exponential function are of the form

y = ab^x

----------------------

To find "a" plug in x = 0 y = 0.2

0.2 = a(0.2)^0

0.2 = a

-------------------------

To find "b" plug in another point and a = 0.2

using x = 2, b = 0.05

0.05 = 0.2b^2

Divide both sides by 0.20

.25 = b^2

Take the square root of both sides

0.5 = b

-----------------------------

With a = 0.2 and b = 0.5 the equation becomes

y = 0.2(0.5)^x

Answer:

what did percent or fraction did she give Kendall?

Step-by-step explanation:

Answer:

The correct solution is "x=3 or x=9".

Step-by-step explanation:

The given equation is:

⇒  [tex]x^2 - 12x + 49 = 22[/tex]

On subtracting "22" from both sides, we get

⇒  [tex]x^2-12x+49-22=22-22[/tex]

⇒          [tex]x^2-12x+27=0[/tex]

On factorizing the above equation, we get

⇒  [tex]x^2-9x-3x-27=0[/tex]

By taking common, we get

⇒  [tex]x(x-9)-3(x-9)=0[/tex]

⇒          [tex](x-3)(x-9)=0[/tex]

⇒                        [tex]x-3=0[/tex]

                                 [tex]x=3[/tex]

Or,

⇒                        [tex]x-9=0[/tex]

                                [tex]x=9[/tex]
