Answer:

Side GI= 2

Step-by-step explanation:

Photo attached, used SOH CAH TOA method.

The  difference between two positive numbers is 7 and the difference between these  cubes is 805. If 'A' represents their product and 'B' represents the sum of their squares,

So,

Let the number be n and m

A = n × m = nm

B = n² + m² = (n + m)²

Now

n³ - m³ = 805

(n - m) (n² + m² + nm) = 805

Since difference is 7

7 × n² + m² + nm = 805

n² + m² + nm = 805/7

n² + m² + nm = 115

(n² + n) + (m² + m) = 115

A + B = 115

Now

On squaring the first eq.

(n - m)² = (7)²

(n - m)² = 49

B - 2A = 49

Now

A + B - B + 2A = 115 - 49

A + 2A = 66

3A = 66

A = 66/3

A = 22

By using 2

B - 2(22) = 49

B - 44 = 49

B = 49 + 44

B = 93

A - B = 22 - 93 = -71

Answer:

y = 20

x = 120

Step-by-step explanation:

2x + 3y = 300

3x + 5y = 460

mutliply eqn 1 by 3 and 2 by 2

6x + 9y = 900

6x + 10y = 920

y = 20

x =

Both values have the same exponent ( they are both 10^20) so first subtract the numbers:

8.64 - 7.83 = 0.81

You would now have 0.81 x 10 ^20

But to be in scientific notation you need a number to the left of the decimal.

0.81 would become 8.1 and because you move the decimal 1 place to the left, you would subtract 1 from the original exponent so 10 ^20 would become 10 ^19

The answer is 8.1 x 10 ^ 19

Answer:

B = 0.81 x 10^ 20

Step-by-step explanation:

=(8.64 x 10^ 20)- (7 83x 10^20)

=8.1 x 10^19

which is also written as

= 0.81x 10^20

Answer:

9.64797292×10^28

Step-by-step explanation:

Answer:

$45.90

Step-by-step explanation:

Multiply without the decimal points, then put the decimal point in the answer: 85 x 54 = 4590

8.5 has 1 decimal place

5.4 has 1 decimal place

Therefore, the answer has 2 decimal places

= 45.90

Refine: 45.9

The answer is 45.9

Answer:

y= -1/4x+2

Step-by-step explanation:

y=mx+b is the slope intercept form.

We first must isolate y by adding 1/2x on both sides.

-2y=-4+1/2x

next we multiple by -1/2 to get rid of the -2

y=2-1/4x

y=-1/4x+2

Answer:

x= [tex]5\sqrt{5}[/tex]

Step-by-step explanation:

To solve this problem we first observe the Pythagoras equation. If a= 10 and b =5 are the lengths of the legs of a right triangle and c= x is the length of the hypotenuse, then the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.

This relationship is represented by the formula:

[tex]a^{2} + b^{2} = c^{2}[/tex] =>[tex]10^2 +5 ^2 = x^2[/tex]

=> 100 + 25 = [tex]x^2[/tex]

=> [tex]\sqrt{125}[/tex] = x => [tex]\sqrt{25} \sqrt{5}[/tex] = x

=> x= 5[tex]\sqrt{5}[/tex]

Answer:

the answer is altitudes.

Step-by-step explanation:

i am not much sure of that.

Answer:

Triangle :

Step-by-step explanation:

        The altitude of triangles,

Three altitudes :

Every triangle has three bases (any of its sides) and three altitudes (heights). Every altitude is the perpendicular segment from a vertex to its opposite side (or the extension of the opposite side).

         The heights. of triangle,

The three heights of a triangle :

Triangles each have three heights, each related to a separate base. Regardless of having up to three different heights, one triangle will always have only one measure of area. In some triangles, like right triangles, isosceles and equilateral triangles,

Answer:

68:76.5

Step-by-step explanation:

create the ratio 68/x=8/9, then simplify the side you can so get 68/x=.8888... then multiply both sides by x to get rid of the fraction, 68=.8888...x. now divide both sides by .8888... to get x by itself, 76.5=x

Answer:

Step-by-step explanation:

1) y = 50x + 2500

2) y = 200x + 1000

if we build a system with the two equations, we have:

50x+2500 = 200x + 1000

150x = 1500

x = 10

y = 2000 + 1000 = 3000

3) 10

4) $3000

Answer:

It is not a right triangles because 15^2 + 13^2 is NOT EQUAL to 19^2

let x, y, and z be the angles inside the triangle.

Law of cosines says:

19^2 = 13^2 + 15^2 - 2(13)(15)cos x

361 = 169 + 225 - 390 cos x

-33 = -390 cos x

-33/-390 = cos x

11/130 = cos x

x = inverse cosine (11/130)

= 85.14609471338569.....

Per law of sines:

sin x/19 = sin y / 13

(13/19)sinx = sin y

inverse_sine ( (13/19) sin x) = y

y = 42.9810733896016548....

Per law of sines

sin x/19 = sin z / 15

z = inverse_sine( (15/19) sin x)

= 51.8728352950227805....

So it is an acute triangle and yes, these angles add up to 180

Answer:

3 triangles

Step-by-step explanation:

Perimeter of triangle = a + b + c

Given that :

P = 12

and a, b, c are natural numbers

Let :

Side A = a

Side B = b

Side C = 12 - (a + b)

Side A + side B > side C - - - (condition 1)

a + b > 12 - (a + b)

a + b > 12 - a - b

a + a + b + b > 12

2a + 2b > 12

2(a + b) > 12

a + b > 6

Side A - side B < side C

a - b < 12 - (a + b)

a - b + a + b < 12

2a < 12

a < 6

b < 6 (arbitrary point)

Going by the Constraint above :

The only three possibilities are :

(2, 5, 5)

(3, 4, 5)

(4, 4, 4)

Total number of triangle = 3

Equilateral triangle (all 3 sides equal) = (4, 4, 4) = 1

Isosceles triangle (only 2 sides equal) = (2, 5, 5) = 1

Answer:

96

Step-by-step explanation:

To get 5 digit numbers using the digits 0,1,2,3,4 exactly once = 4*4*3*2*1 = 96.

Step 1:

1st digit can be 1, 2,3,4 ( it can't be 0) so there are 4 choices.

Step 2:

2nd digit = 4 choices.

Step 3:

3rd digit = 3 choices

Step 4:

4th digit = 2 choices

Step 5:

5th digit = 1 choice .

So the number of different 5 digit number is 4*4*3*2*1 = 96
