Answer:

1.Corresponding angles theorem

2.Linear postulate

3.By the definition of supplementary angles

Step-by-step explanation:

We are given that  

[tex]w\parallel x \ and \ y[/tex] is a transversal.

We have to prove [tex]\angle 3[/tex] and [tex]\angle 5[/tex] are supplementary

Proof:

1.Given that [tex]w\parallel x \ and \ y[/tex] is a transversal.

We know that [tex]\angle 1\cong \angle 5[/tex]

Reason:Corresponding angles theorem

Therefore, [tex]m\angle 1=m\angle 5[/tex]

by the definition of congruent.We also know that, by definition, angle 3 and angle 1 are a linear pair.

Therefore, they are supplementary by linear pair postulate

By the definition of supplementary angles

[tex]m\angle 3+m\angle 1=180^{\circ}[/tex]

Now, we can substitute [tex]m\angle 5=m\angle 1[/tex]

Then, we get

[tex]\m\angle 3+m\angle 5=180^{\circ}[/tex]

Therefore, by the definition of supplementary angles,angle 3 and angle 5 are supplementary

Answer:

1. Corresponding angles theorem

2. Linear pair postulate

3. Definition of supplementary angles

Answer:

a.114.4kg

b. 486kg

Step-by-step explanation:

Firstly , we want to know the value with which the apples weigh more than the oranges

To calculate this, we simply subtract the weight of the oranges from that of the apple

Mathematically, that would be ;

300.2-185.8 = 114.4kg

The total weight of the things bought is calculated by adding both weights together

That would be 185.8 + 300.2 = 486 kg

Answer:

15 inches

Step-by-step explanation:

We can solve this problem using the Pythagorean theorem. The formula is:

[tex]a^{2} + b^{2} = c^{2}[/tex]

where 'c' is the hypotenuse (the longest side) and 'a' and 'b' are the legs (the other sides).

First, draw a diagram for the problem. (See the photo attached below)

We know the other leg is 8 and the hypotenuse is 17. 'a' is the missing side.

a = ?

b = 8

c = 17

Substitute the values into the equation.

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex]a^{2} + 8^{2} = 17^{2}[/tex]

Rearrange to isolate 'a'

[tex]a^{2} = 17^{2} - 8^{2}\\[/tex]               Square root both sides

[tex]a = \sqrt{17^{2} - 8^{2}}[/tex]             Square each number

[tex]a = \sqrt{289-64}[/tex]             Subtract under the root

[tex]a = \sqrt{225}[/tex]                     Find the square root

[tex]a =15[/tex]                          Final answer

Therefore, the TV is 15 inches tall.

Answer:

314.16 m

Step-by-step explanation:

The distance across the track is 100 metres. This means that the diameter is 100 m.

The track is circular, so, we need the circumference.

The circumference of a circle is given as:

C = πD

where D = diameter

Therefore, the circumference of the track is:

C = π * 100 = 314.16 m

She walked a distance of 314.16 m

Answer:

20 days.

Step-by-step explanation:

In this case we must make an inverse proportionality rule, it is inverse because the fewer people there are, the more days must survive. In other words, we know that 2000 people can resist for 15 days, now, if there are no longer 2000 people, but 500 less, that is, 1500 (2000 - 500) how many days can they resist.

people    days

 2000       15

 1500         x

x = 2000 * 15/1500

x = 20

That is, they could last 20 days.

I don't know what general 5' form means, but I'm guessing that means slope-intercept form, the easiest form of a linear equation. So we can use the equation for this is y = mx+b. M being slope, and b is the y-intercept. So that means that we will get an answer of:

y = 1x+5, you spelled 1 wrong so I just correct it.

The exponential function represented on the graph is f(x) = (1/3)[tex].^x[/tex]. The correct option is B.

The mathematical expression f(x)=exp or e^x denotes the exponential function. The word, unless specifically stated differently, normally refers to the positive-valued function of a real variable, though it can be extended to complex numbers or adapted to other mathematical objects like matrices or Lie algebras.

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

The given graph is representing the exponential function f(x) = (1/3)[tex].^x[/tex] The graph is attached with the answer below. The graph is showing the inverse fraction of ( 1/3).

Answer:

2250m

Step-by-step explanation:

Step 1

Since

Hence,

tan x = 3/4

tan y=5/7

tan x = BA/ CA where BA = height and CA = distance

3/4 = h/ d

4h = 3d

h = 3d/4.......... Equation 1

tan y = BA / DA + 150m

5/7 = h/d + 150

7 × h = 5(d + 150)

7h = 5d + 750............ Equation 2

Since h = 3d/4

7(3d/4) = 5d + 750

21d/4 = 5d + 750

Multiply both sides by 4

21d = 4(5d + 750)

21d = 20d + 3000

21d -20d = 3000

d = 3000

Distance (d) = 3000m

Substitute 3000m for d in equation 1

h = 3d/4

h = 3 × 3000/4

h = 2250m

Answer:

Step-by-step explanation:

[tex]tangent=\dfrac{opposite}{adjacent}[/tex]

We have:

[tex]\tan x^o=\dfrac{3}{4}\\\\\tan y^o=\dfrac{5}{7}[/tex]

By definition of tangent, we have:

[tex]\tan x^o=\dfrac{AB}{AC}\\\\\tan y^o=\dfrac{AB}{AC+150}[/tex]

Therefore we have the system of equations:

[tex]\left\{\begin{array}{ccc}\dfrac{AB}{AC}=\dfrac{3}{4}&(1)\\\\\dfrac{AB}{AC+160}=\dfrac{5}{7}&(2)\end{array}\right[/tex]

From (1)

[tex]\dfrac{AB}{AC}=\dfrac{3}{4}[/tex]             cross multiply

[tex]3AC=4AB[/tex]         divide both sides by 3

[tex]AC=\dfrac{4AB}{3}[/tex]

Substitute it to (2):

[tex]\dfrac{AB}{\frac{4AB}{3}+150}=\dfrac{5}{7}\\\\\dfrac{AB}{\frac{4AB}{3}+\frac{3\cdot150}{3}}=\dfrac{5}{7}\\\\\dfrac{AB}{\frac{4AB}{3}+\frac{450}{3}}=\dfrac{5}{7}\\\\\dfrac{AB}{\frac{4AB+450}{3}}=\dfrac{5}{7}\\\\AB\cdot\dfrac{3}{4AB+450}=\dfrac{5}{7}[/tex]

[tex]\dfrac{3AB}{4AB+450}=\dfrac{5}{7}[/tex]            cross multiply

[tex](3AB)(7)=(5)(4AB+450)\\\\21AB=(5)(4AB)+(5)(450)[/tex]

[tex]21AB=20AB+2250[/tex]         subtract 20AB from both sides

Answer:

Answer:

x = -2

y = 3

Step-by-step explanation:

You are given a system of two linear equations:

-2x + 3y = 13

3x + 4y = 6

One of the good ways to solve this system is trying to eliminate one variable (x or y), calculate the remaining variable and substitute the calculated variable back into system to solve for eliminated variable.

Here, we will manipulate the original system, so that we can easily eliminate x.

Let's multiply both sides of the first equation by 3 and the second equation by 2 (this manipulating step does not change the original system of equations).

3*(-2)x + 3*3y = 3*13

2*3(x) + 2*4y = 2*6

<=>

-6x + 9y = 39

6x + 8y = 12

Now, we add up two equations, left side + left side, right side + right side, we obtain:

-6x + 9y + 6x + 8y = 39 + 12

or

17y = 51

We divide both sides of equation by 17, to get y.

=> y = 51/17 = 3

Substitute y = 3 back into the first equation of system (or the second equation, it doesn't matter, here we choose the first one).

=> -2x + 3*3 = 13

=> -2x + 9 = 13

=> -2x = 4

=> x = -2

=> The solution of this system is (x, y) = (-2, 3)

Hope this helps!
