Answer:

[tex]x = \frac{57}{29} \ , \ y = \frac{12}{29}[/tex]

Step-by-step explanation:

                            2x + 5y = 6     --------( 1 )

                            5x - 2y = 9     --------( 2 )

                        _____________

     ( 1 ) x 5 =>     10x + 25y = 30   -----------( 3 )

     ( 2 ) x 2 =>    10x - 4y = 18       ----------- ( 4 )

                       ______________

    ( 3 ) - ( 4 ) =>    0 +  29y = 12

                                   [tex]y = \frac{12}{29}[/tex]

Substitute y in ( 1 ) =>

                            [tex]2x + (5 \times \frac{12}{29}) = 6\\\\2x + \frac{60}{29} = 6\\\\2x = 6 - \frac{60}{29}\\\\2x = \frac{174 - 60}{29}\\\\x = \frac{114}{29 \times 2}\\\\x = \frac{57}{29}[/tex]

Answer:

The answer is below

Step-by-step explanation:

The ramp has the form of a triangle. The height of the ramp is the vertical side of a triangle, the top of the frame is the hypotenuse while the length of the ramp is the base side of the triangle.

Let the hypotenuse be b, length be a and height be c Hence:

b² = a² + c²

b² = 3² + 5²

b² = 9 + 25

b² = 34

b = 5.83 feet

B) The plywood needs to be 5.83 feet long

C) Since the top of the ramp is 10 feet, let us assume the height of the ramp to be 6 feet, hence, the length of the ramp a is:

10² = a² + 6²

100 = a² + 36

a² = 64

a = 8 feet

Answer: [tex]x=2[/tex]

Step-by-step explanation:

Let's solve your equation step-by step

[tex]3(4-2x)=x-2[/tex]

First we need to use the distributive property

[tex](3)(4)-(3)(2x)=x-2\\-6x+12=x-2[/tex]

Now let's subtract x from both sides

[tex]-6x+12-x=x-2-x\\-7x+12=-2[/tex]

Next let's subtract 12 from both sides

[tex]-7x+12-12=-2-12\\-7x=-14[/tex]

Finally divide both sides by -7

[tex]\frac{-7x}{-7} =\frac{-14}{-7} \\x=2[/tex]

Answer:

0.1007

Step-by-step explanation:

Given :

Average gain, μ = 0.8

Standard deviation, σ = 0.7

Number of companies, n = 20

Obtaining the standardized value ;

Zscore = (x - mean) / (σ/√n)

Zscore = (1 - 0.8) / (0.7/√20)

Zscore = (0.2 / 0.1565247)

Z = 1.27775

Using the Z probability calculator :

P(Z > 1.27775) = 0.10067

P(Z > 1.27775) = 0.1007 ( Z probability calculator)

Answer:

After the third bounce the ball reaches a height of less than 50cm.

Step-by-step explanation:

Geometric sequence:

In a geometric sequence, the quotient between consecutive terms is always the same, and it's called common ratio. The nth term of a geometric sequence is given by:

[tex]A_n = A_0(r)^{n}[/tex]

In which [tex]A_0[/tex] is the first term and r is the common ratio.

A ball is dropped from a height of 5m.

This means that [tex]A_0 = 5[/tex]

After each bounce it rises to 35% of its previous height.

This means that [tex]r = 0.35[/tex]

Thus

[tex]A_n = A_0(r)^{n}[/tex]

[tex]A_n = 5(0.35)^{n}[/tex]

After how many bounces does the ball reach a Height of less than 50cm?

50cm = 0.5m. This is n for which [tex]A_n = 0.5[/tex]. Thus

[tex]A_n = 5(0.35)^{n}[/tex]

[tex]0.5 = 5(0.35)^{n}[/tex]

[tex](0.35)^n = \frac{0.5}{5}[/tex]

[tex](0.35)^n = 0.1[/tex]

[tex]\log{(0.35)^n} = \log{0.1}[/tex]

[tex]n\log{0.35} = \log{0.1}[/tex]

[tex]n = \frac{\log{0.1}}{\log{0.35}}[/tex]

[tex]n = 2.19[/tex]

Rounding up:

After the third bounce the ball reaches a height of less than 50cm.

The current population of Madagascar is 28,354,778 as of Thursday, June 10, 2021, based on Worldometer elaboration of the latest United Nations data.

Madagascar 2020 population is estimated at 27,691,018 people at mid year according to UN data.

Madagascar population is equivalent to 0.36% of the total world population.

Madagascar ranks number 51 in the list of countries (and dependencies) by population.

The population density in Madagascar is 48 per Km2 (123 people per mi2).

The total land area is 581,795 Km2 (224,632 sq. miles)

38.5 % of the population is urban (10,670,252 people in 2020)

Answer:         for the first one x>-6, for the second one x< or equal to 5

Step-by-step explanation:

Answer:

25 x 0.84 ^ h = X

After 4 hours there will be 12.45 milligrams of the medicine, and after 8 hours there will be 6.20 milligrams of it.

Step-by-step explanation:

Given that a particular medicine decays at a rate of 16% every 4 hours, if a person takes a 25 mg dose, to write a function that represents the amount of medicine after h hours, and determine how much is left after 4 hours and 8 hours, the following calculations must be performed:

100 - 16 = 84

25 x 0.84 ^ h = X

25 x 0.84 ^ 4 = X

25 x 0.4978 = X

12.45 = X

25 x 0.84 ^ 8 = X

25 x 0.2478 = X

6.20 = X

Therefore, after 4 hours there will be 12.45 milligrams of the medicine, and after 8 hours there will be 6.20 milligrams of it.

Answer:

16.0"

Step-by-step explanation:

ASSUME the pyramid is a square right pyramid.

height = 15"

base side length = 11"

(Following edited/corrected thanks to cwrw238)

Slant height

= sqrt(5.5²+15²)   using Pythagoras theorem

= sqrt(255.25)

=  15.98"

Answer:

Slant height = 15.98 in to nearest hundredth.

Step-by-step explanation:

Use Pythagoras theorem.

The triangle we want  has a height of 15 , base of 1/2*11 = 5.5 and we need the length of the hypotenuse.

h^2 = 5.5^2 + 15^2 = 255.25

h = 15.976.

Answer:

B =43.7

Step-by-step explanation:

take angle b as reference angle

using sin rule

sin B =opposite/hypotenuse

sin B =9/13

sin B =0.69

[tex]B =sin^{-1} (0.69)[/tex]

B =43.63

B =43.7

(x-4)²+(y-6)² =100 is the equation of the circle with a center of (4,6) and a radius of 10 units

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

The standard equation of a circle is (x-h)²+(y-k)² =r²

In the equation (h, k) represents the center of the circle.

r is the radius of the circle.

From given that circle with a center of (4,6) and a radius of 10 units.

We need to find the equation of the circle.

Substitute h=4, k=6 and r=10

We get  (x-4)²+(y-6)² =10²

Hence,   (x-4)²+(y-6)² =100 is the equation of the circle with a center of (4,6) and a radius of 10 units.
