Answer:

a) The fact that corresponding angles are equal

b) The fact that alternate angles are equal

Step-by-step explanation:

I hope this helps

a) Measure of corresponding angles are equal.

b) Pair of alternate interior angles are of equal measure.

We know when a transversal intersects two parallel lines at two distinct points,

Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.

From the given figure the fact used to fund the measure of the angle r is

corresponding angles.

The fact that is used to find the angle t is in a parallelogram measure of opposite angles are equal.

Also, r and t are pairs of alternate interior angles so they measure the same.

Answer:D

Step-by-step explanation::

We may infer from the number line that A and B are separated by 8 units (AB).

Let AB stand for the separation between points A and B, and let AC stand for the separation between points A and C. Let B stand for the separation between points B and C. Hence:

Point B being halfway between A and C, we can infer:

AB + BC Equals AC (Postulated segment addition)

As a result, since the distance between points A and B is equal to 1/3 of AC:

AC/3 = AB = 1/3(AC)

But as shown in the accompanying image:

AC equals 16 – (–8) to 24 units.

Therefore:

AB = 1/24 = 8 unit

A and B are separated by 8 units.

1) Earth is 403,400,000 miles farther from Saturn than it is from Jupiter.

2) The total distance from Saturn to Jupiter and from Jupiter to Mars is 745,400,000 miles.

3) Saturn is 390,000,000 miles closer to Jupiter than is is to Earth.

4) Total distance from Mercury to Earth is 56,700,000 miles.

5) Venus is 22,300,000 miles closer to Earth than Mars.

6) Earth is 745,000,000 miles farther from Mars than Saturn.

Given,

1) Distance from Earth to Saturn = 793,000,000 miles

  Distance from Earth to Jupiter = 390,400,000 miles

793,000,000 - 390,400,000 = 403,400,000

That is, Earth is 403,400,000 miles farther from Saturn than it is from Jupiter.

2) Distance from Saturn to Jupiter = 403,400,000 miles

   Distance from Jupiter to Mars = 342,000,000 miles

403,400,000 + 342,000,000 = 745,400,000

Therefore, the total distance from Saturn to Jupiter and from Jupiter to Mars is 745,400,000 miles.

3) Distance from Saturn to Jupiter = 403,400,000 miles

   Distance from Saturn to Earth = 793,800,000 miles

793,800,000 - 403,400,000 = 390,400,000

So, Saturn is 390,000,000 miles closer to Jupiter than is is to Earth.

4) Distance from Mercury to Venus = 30,700,000 miles

   Distance from Venus to Earth = 26,000,000 miles

30,700,000 + 26,000,000 = 56,700,000

That is, the total distance from Mercury to Earth is 56,700,000 miles.

5) Distance from Earth to Venus = 26,000,000 miles

   Distance from Earth to Mars = 48,300,000 miles

48,300,000 - 26,000,000 = 22,300,000

That is, Venus is 22,300,000 miles closer to Earth than Mars.

6) Distance from Earth to Saturn = 793,800,000 miles

   Distance from Earth to Mars = 48,300,000 miles

793,800,000 - 48,300,000 = 745,500,000

That is, Earth is 745,000,000 miles farther from Mars than Saturn.

The equivalent expression of the given expression is 5n/4 -3/8

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Here, the given expression is :

(-2 ¹/₂n + ¹/₄) + (3 ³/₄n - 5/8)

simplifying the above expression by taking like considering like terms :

= -2 ¹/₂n + 3 ³/₄n +  ¹/₄- 5/8

= (15/4)n - (5/2)n + (2-5)/8

= (15-10)n/4 -3/8

= 5n/4 -3/8

Therefore, the equivalent expression of the given expression is 5n/4 -3/8.

Answer:

10.25

Step-by-step explanation:

Define the variable

Let x be the unknown number.

Therefore:

[tex]\begin{aligned}& \textsf{Four times a number}: \quad & 4x\\& \textsf{Twenty less than four times a number}: \quad & 4x-20\\& \textsf{Twenty less than four times a number is twenty one}: \quad & 4x-20=21\end{aligned}[/tex]

To find the number, solve the found equation for x:

[tex]\begin{aligned}\implies 4x-20&=21\\4x-20+20&=21+20\\4x&=41\\\dfrac{4x}{4}&=\dfrac{41}{4}\\x&=10.25\end{aligned}[/tex]

Therefore, the unknown number is 10.25.

As an improper fraction, this is ⁴¹/₄.

As a mixed number, this is 10 ¹/₄.

Answer:

x = 10.25

Step-by-step explanation:

Given that,

→ Twenty less than four times a number is twenty one.

The equation we form,

→ 4x - 20 = 21

Now the value of x will be,

→ 4x - 20 = 21

→ 4x = 21 + 20

→ x = 41/4

→ [ x = 10.25 ]

Hence, the number is 10.25.

Mediante la ley del seno, la longitud del faro es aproximadamente igual a 8.295 metros.

En esta pregunta nos encontramos con una sistema geométrico con dos ángulos y un lado conocidos, la configuración permite determinar la altura del faro mediante la ley del seno, cuya expresión sería la siguiente:

AC / sin B = AB / sin C = BC / sin A      

Donde BC es la longitud del faro, medida en metros, y AC es la distancia horizontal hasta la base del faro, medida en metros. Si sabemos que AC = 9.9 m, B = 53° and A = 42°, entonces la longitud del faro es:

(9.9 m) / sin 53° = BC / sin 42°

BC = 9.9 m × (sin 42° / sin 53°)

BC ≈ 8.295 m

La longitud del faro es aproximadamente igual a 8.295 metros.

The amount that should be invested is the present value of the $8,000 for the next 5 years. This amount would be the present value of an annuity due because constant payments that come at the beginning of a period are annuity dues.

Present value of annuity due = Annuity due x (Present value interest factor of annuity due, 6%, 5 years)

False, because the inequality is not less than or equal to 14 it should a bracket instead of paratheses. [3, 14]

Graph of g is a translation where g(x) = (x+2)^2 - 2x – 1

f(x) = x^2 - 2x

g(x) = f(x+2) + 3

Translation is a movement of the graph either horizontally parallel to the x-axis or vertically parallel to the y-axis. A translation is a geometric transformation that moves every point of a figure, shape or space by the same distance in a given direction. A translation can also be interpreted as the addition of a constant vector to every point, or as shifting the origin of the coordinate system. In a Euclidean space, any translation is an isometry.

Hence , g(x) = (x+2)^2 -2(x+2) + 3 = (x+2)^2 - 2x - 1. When we graph the equations, we can confirm that our answer is correct.

Answer: 24

Step-by-step explanation: HI = 2 times KL

-8x + 120 = 2(-8x + 96)

-8x + 120 = -16x + 192

x = 9

KL = -8x + 96

KL = -8(9) + 96

KL = 24

The measure of the supplementary angles are 34.3 and 145.7 degrees.

Supplementary angles are those angles that sum up to 180 degrees.

In other words, two angles are Supplementary when they add up to 180 degrees.

Therefore, the angles measures 111.4° more than the measure of it's supplementary angle.

Hence,

let

x = measure of the other angle

x + x + 111.4 = 180

2x + 111.4 = 180

subtract 111.4 from both sides

2x + 111.4 - 111.4 = 180 - 111.4

2x = 68.6

divide both sides by 2

x = 68.6 / 2

x = 34.3

Other angle  = 34.3 + 111.4 = 145.7°

Therefore, the measure of the supplementary angles are 34.3 and 145.7 degrees.

Answer:

$191.29

Step-by-step explanation:

Use the formula
[tex]A = P(1 + \dfrac{r}{100})^n[/tex]

where P is amount deposited, A the accrued amount, n number of years and r the interest rate in % compounded annually

The division by 100 is necessary to convert r% to a decimal for calculations

We have P = 850, r = 7% and n = 3

Plugging these in we get
[tex]A = 850\cdot (1 + (\dfrac{7}{100})^3\\\\A= 850\cdot(1 + 0.07)^3\\A = 850\cdot1.07^3\\\A = \$1,041.29[/tex]

Interest = A - P = 1041.29 - 850 = $191.29
