Step-by-step explanation:Communative property.

Answer:

The correct option is (3) 40/9.

Step-by-step explanation:

Consider the right angled triangle attached below.

The angle FDE is the right angle.

Using the trigonometric identities for right angled triangles compute the tangent of the measure of angle DFE as follows:

tan (DFE) = DE/DF

                = 40/9

Thus, the correct option is (3) 40/9.

Answer:

C. 40/9

Step-by-step explanation:

Answer: Not a solution of the System

Step-by-step explanation:

Plug in 0 for x and 2 for y for both equations.

Note, if only one of the equations is a true statement

(0.2) is not a solution. If either one of the equation is not true, the ordered pair is not a solution.

0+3(2)=4

3*2=6

0+6=6

6≠4

This was only the first equation but it was not true.

The equation is not true, so (0, 2) is not a solution of the second equation.  Therefore, (0, 2) is not a solution of the system of equations.

To determine graphically whether the ordered pair (0, 2) is a solution of the system of equations, we can plot the two equations on a graph. If the point (0, 2) lies on both lines, then it is a solution of the system.

The first equation is x + 3y = 4.  To plot this equation, we can first solve for y:

y = -(1/3)x + 4/3

This equation has a slope of -1/3 and a y-intercept of 4/3.  So, the line will rise 1 unit for every 3 units it moves to the left.  The y-intercept is 4/3, so the line will pass through the point (0, 4/3).  Three units to the left of (0, 4/3) is (-3, 7/3), so the line will also pass through this point.

The second equation is 3x + y = -2.  To plot this equation, we can first solve for y:

y = -3x - 2

This equation has a slope of -3 and a y-intercept of -2.  So, the line will fall 3 units for every 1 unit it moves to the right.  The y-intercept is -2, so the line will pass through the point (0, -2).  One unit to the right of (0, -2) is (1, -5), so the line will also pass through this point.

We can  check this algebraically.  Substituting (0, 2) into the first equation, we get:

0 + 3× 2 = 4

6 ≠ 4

This equation is not true, so (0, 2) is not a solution of the first equation.  Substituting (0, 2) into the second equation, we get:

3  × 0 + 2 = -2

2 = -2

This equation is also not true, so (0, 2) is not a solution of the second equation.  Therefore, (0, 2) is not a solution of the system of equations.

Answer:

b = a + 2 or b = 2 - a

Step-by-step explanation:

Solve for b:

-4 + a^2 + 4 b - b^2 = 0

The left hand side factors into a product with two terms:

(2 + a - b) (-2 + a + b) = 0

Split into two equations:

2 + a - b = 0 or -2 + a + b = 0

Subtract a + 2 from both sides:

-b = -a - 2 or -2 + a + b = 0

Multiply both sides by -1:

b = a + 2 or -2 + a + b = 0

Subtract a - 2 from both sides:

Answer:

b = a + 2 or b = 2 - a

Answer:

y - x = - 5

Step-by-step explanation:

Applying the rule gives

x = [tex]\frac{1}{3}[/tex] × 36 + 9 = 12 + 9 = 21

y = [tex]\frac{1}{3}[/tex] × 21 + 9 = 7 + 9 = 16

Answer:

Option C

Step-by-step explanation:

=> 4p + 2 = 8

Subtracting 2 to both sides

=> 4p = 8-2

=> 4p = 6

Dividing both sides by 4

=> p = 1.5

Answer:

The answer is C.

Step-by-step explanation:

First, you have to subtract 2 to both sides :

[tex]4p + 2 = 8[/tex]

[tex]4p + 2 - 2 = 8 - 2[/tex]

[tex]4p = 6[/tex]

Next, you have to divide it by 4 :

[tex]4p = 6[/tex]

[tex]p = 6 \div 4[/tex]

[tex]p = 3 \div 2[/tex]

[tex]p = 1.5[/tex]

Answer:

The measure of angle a is 43 degrees.

Step-by-step explanation:

Angle P is congruent to Angle R. A triangle's angles add up to 180 degrees. 47*2=94. 180-94=86 degrees. 86/2=43 degrees.

Answer: 43°

Step-by-step explanation:

The degree of a triangle adds up to 180. We are given an angle of 47 and there is a right angle of 90

We now have 90 + 47 + a = 180

137 + a = 180

a = 43

Answer:

- 156250

Step-by-step explanation:

Find the ratio of the geometric sequence.

-10/2 =  -5

50/-10 = -5

The common ratio is -5.

Apply the formula.

an = ar^(n-1)

Where a is the first term and r is the ratio.

a8 = 2(-5)^(8-1)

a8 = 2(-5)^7

a8 = 2(-71825)

a8 = -156250

Answer:

78 red apples

Step-by-step explanation:

Set up the equations

r + y + g = 130

y = 3g

r = 2y

If r = 2y and y = 3g, then r = 6g

Plug in the two equations, y = 3g, and r = 6g

6g + 3g + g = 130

10g = 130

g = 13

Plug in 13 as g in the equation r = 6g

r = 6(13)

r = 78

There were 78 red apples

Step-by-step explanation:

Simple Interest = PTR/100

=1000* 30* 6/100

=1800.

Amount= Principal + Interest

= 1000+1800

= $2800

The amount of money that has at the of 30 years is $​2800.

Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time.

Unlike compound interest, which adds the interest from the principal of prior years to determine the interest of the following year, the principal amount in simple interest remains constant.

As per the given,

Principle amount P = $1000

Rate of interest R = 6%

Time span T = 30 years.

Total amount = Principle amount + Interest

Total amount = P + (PRT)/100

Total amount = $1000 + (1000 x 6 x 30)/100

⇒ $2800

Hence "The amount of money that has at the of 30 years is $​2800".

Answer:

35 acres

Step-by-step explanation:

We have 15.8 happys per acre and the we have exactly 553 happys living in happy land.

To calculate the number of acres, we just need to divide the number of happys we have by the number by the number of happys per acre

Mathematically, that would be 553/15.8 = 35 acres

Happyland have 35 acres of Land.

Given to us:

Population of Happyland = 553 Happys

Population of Happyland per acre = 15.8 Happys per acre,

Land with Happyland in acres:

[tex]\rm {Land with Happyland in acres =\dfrac{ Total\ number\ of\ Happys}{Population\ of\ Happyland\ per\ acre}}[/tex]

Putting in the value we get,

[tex]\rm {Land with Happyland in acres =\dfrac{ Total\ number\ of\ Happys}{Population\ of\ Happyland\ per\ acre}}\\\\\rm {Land with Happyland in acres =\dfrac{553}{15.8}}\\\\\rm {Land with Happyland in acres = 35 acres[/tex]
