=====================================================
Explanations:
Angles 1 and 2 are vertical angles because they are opposite one another in this X configuration. Vertical angles are always congruent.These angles are alternate interior angles because they are inside the parallel lines (hence the "interior") and they are on alternating sides of the transversal cut.The two angles shown here form a straight line, so that's what makes them supplementary. Supplementary angles add to 180 degrees.Angle 4 and angle 5 are on alternating sides of the transversal, but this time they are outside the parallel lines. So that's why we go for alternate exterior this time. Angles 5 and 6 are in the same southwest corner of each four-corner configuration, which makes them corresponding angles.It's the same idea as problem 4Same idea as problem 3.Same idea as problem 2.Same idea as problems 4 and 6.---------------
None of the angle pairs mentioned are consecutive interior angles. These types of angles are on the same side of the transversal, and inside the parallel lines. So we never use option 'a'. We cross off option h as well for pretty much identical reasoning. Options 'a' and h are the same thing, just slightly different wording.
We cross off option b as well because none of the angles add up to 90 degrees.

Find the value of x.
A 9
В. 18
C 45
D. 90
Answers
Answer:
they are opposite degrees so we can say that 4x=2y-x
Step-by-step explanation:
5x=2y and we complete 4x+(2y+x)=180. and then 5x+2y=180. put 2y from 5x. 4y=180 y= 45 and x= 18°
Now,
(2y + x)° + (2y - x)° = 180° ( straight angle )
or, 2y + x + 2y - x = 180°
or, 4y = 180°
◆ y = 45°
Then,
4x = 2y - x ( vertically opposite angle )
or, 4x = 2*45° - x
or, 5x = 90°
or, x = 90°/5
◆ x = 18 °

Answer:
to do this lets first solve this so
5*5*5*5=625
5^-3=0.008

Answer:
[tex]A_X=\frac{15x^2}{16}[/tex]
Step-by-step explanation:
From the question we are told that:
Base of Flower bed [tex]b=\frac{x}{2}[/tex]
Height of Flower bed [tex]h=\frac{x}{4}[/tex]
Generally the equation for Area of garden left A_X is mathematically given by
[tex]A_X=Area\ of\ Garden\ A_g\ - Area\ of\ flower\ bed\ A_f[/tex]
Where
[tex]A_f=b*h[/tex]
[tex]A_f=\frac{1}{2}*\frac{x}{2}*\frac{x}{4}[/tex]
[tex]A_f=\frac{x^2}{16}[/tex]
Therefore
[tex]A_X= A_g - A_f[/tex]
[tex]A_X=x^2-\frac{x^2}{16}[/tex]
[tex]A_X=\frac{15x^2}{16}[/tex]

Kristian buys a meal for $8.40 calculate the fraction of the $72 after buying the computer game which costed $32.40 and the meal. give ur answer in its lowest terms
Answers
Answer:
After buying the meal and the computer game, Kristian has 43.33% of his money left.
Step-by-step explanation:
Given that Kristian buys a meal for $ 8.40, to calculate the fraction of the $ 72 after buying the computer game which cost $ 32.40 and the meal, the following calculation must be performed:
72 = 100
8.40 + 32.40 = X
72 = 100
40.80 = X
40.80 x 100/72 = X
4,080 / 72 = X
56.66 = X
100 - 56.66 = 43,333
Therefore, after buying the meal and the computer game, Kristian has 43.33% of his money left.

Dado un rectángulo cuya base, lado mayor es 15 cm y cuya altura, lado menor, es 10 cm. Calcular el perímetro y el área
ayuda es para hoy doy 5 estrellas
Answers
Answer:
Área de un rectángulo = 150 cm²
El perímetro de un rectángulo = 50 cm
Step-by-step explanation:
Área de un rectángulo = largo × ancho (alto)
= 15 cm × 10 cm
= 150 cm²
El perímetro de un rectángulo = 2L + 2W
Donde L = longitud = 15 cm
W = Ancho = 10 cm
= 2 (15 cm) + 2 (10 cm)
= 30 + 20
= 50cm

25√2
Step-by-step explanation:
Since angle BAC and angle ABC are equal, AB = BC.
Let x = AB = BC
By the Pythagorean theorem,
AB² + BC² = AC²
x² + x² = 50²
2x² = 2500
x²= 1250
x = √1250
x = √(2 • 625)
x = √2 • √625
x = √2 • 25
x = 25√2
x = AB = 25√2

6x+2y=6
7x+3y=5
Answers
Answer:
x = 2, y = -3
Step-by-step explanation:
6x + 2y = 6 (multiplying by 3)
18x + 6y = 18 -----> (i)
7x + 3y = 5 (multiplying by 2)
14x + 6y = 10 -----> (ii)
Subtracting (i) from (ii)
18x + 6y - 14x + 6y = 18 - 10
4x = 8
x = 2
Substituting in (ii)
14x + 6y = 10
14(2) + 6y = 10
28 + 6y = 10
6y = -18
y = -3

Yes, it is
Step-by-step explanation:
A straight line graph is of the general form;
y = mx + b
where m is the slope and b is the y intercept
We can rewrite what we have as

y = -2x/3 + 5/3
As we can see, it can be expressed in the general form and that makes it a straight graph
Here is some information about a holiday.

8% discount if you book before 31 March
On 15 February, Naseem books this holiday for 2 people.
Calculate the total cost of his holiday.
Answers
Answer:
$625.6
Step-by-step explanation:
Information about a holiday:
7 night holiday
$340 per person
8% discount if you book before 31 March
Number of people Naseem booked the holiday for = 2
Date of booking of the holiday = 15 February
Total cost of the holiday per person = cost per person - discount before March 31
= $340 - 8% of $340
= 340 - 8/100 * 340
= 340 - 0.08 * 340
= 340 - 27.2
= $312.8
Total cost of the holiday for 2 persons = 2 × Total cost of the holiday per person
= 2 * $312.8
= $625.6

(4-x^2) is the difference of squares (2^2 - x^2)

Keegan deposited $700 into his bank account. After one year, his bank account balance was $761.60. What interest rate did he earn?

Step-by-step explanation:
We first divide the new amount by the original and close it with brackets.
Our one year will be shown as 1/1 as an indices
(761.60/700)^1/1
= 1.088
We then convert it to 0.088 and times it by 100.
0.088×100= 8.8% Compound interest rate.
This is correct as:

Sean las proposiciones p : "Cinco es mayor que diez" y q : "Dos más dos son cuatro". Escriba en lenguaje natural la proposición ∼p∧q
Answers
Answer:
"cinco es menor o igual que diez, y dos más dos son cuatro"
Step-by-step explanation:
Primero definamos los simbolos utilizados.
∧ significa "y"
∼ es el simbolo de la negación, es decir:
∼p significa "no p"
terminemos de resolver el problema para que el concepto quede claro.
si:
p = cinco es mayor que diez (5 > 10)
entonces:
∼p = cinco es menor o igual que diez (5 ≤ 10)
y
q = dos más dos son cuatro. (2 + 2 = 4)
entonces:
∼p∧q se escribe como:
"cinco es menor o igual que diez, y dos más dos son cuatro"
