Answer:
because they are congruent to the original angle
Step-by-step explanation:
they are congruent to the original triangle. nothing will change.
The two perpendicular lines will remain perpendicular because it should be congruent to the original angle.
What is congruent?The Two geometric figures should treated be congruent in the case when it should have coincided. Since the both perpendicular lines are dilated by the same factor also the same center should be used due to this, the two perpendicular lines should remain perpendicular.
Therefore, The two perpendicular lines will remain perpendicular because it should be congruent to the original angle.

Answer: (x, y)=(0, -6）
Step-by-step explanation:
To solve a system of equations there are usually 3 general ways.
- Elimination
- Substitution
- Augmented Matrix
Since the question is asked to use elimination, we are going to use it.

Jessica wants to buy 6 ounces of gluten-free edible cookie dough that costs $1.50 per ounce. Select all equations that correctly represent how much Jessica will pay for her cookie dough, y .
Answer:
9 dollars
Step-by-step explanation:
Hello you did not provide the options for me to select from. But I have gone ahead to calculate how much jessica would pay for her cookie dough.
I used this formula to arrive at this answer.
Cost of dough = quantity x price per ounce
Quantity = 6 ounces
Price per ounce = 1.5 dollars
Cost of dough = 6 x 1.50
= $9
Jessica is going to pay 9 dollars for her cookie dough
Si el máximo común divisor (MCD) de 6432 y 132 disminuye en 8, entonces será igual a: * 1 punto 6 4 -2 -6
Answer:
4
Step-by-step explanation:
Para empezar el maximo común divisor (MCD) de dos números se refiere al número en común que tienen ambos números, entre los cuales pueden ser divididos. En el caso del máximo se refiere al número más alto posible en que ambos números pueden ser divididos.
Para poder saber esto, es necesario anotar los factores en los cuales pueden ser divididos ambos números. Sin embargo, ya que son cantidades altas, puede tomar mucho tiempo determinar esto, por lo tanto nos vamos a la respuesta final.
Sabemos que el MCD de 132 y 6432 es disminuido en 8 unidades, es decir, se le resta 8 al MCD de esos números, y ese número debe coincidir con alguna de las opciones puesta ahí. Por lo tanto, lo que vamos a hacer para resolverlo rápidamente es sumarle 8 a cada una de las opciones y luego, verificaremos si el número obtenido es divisor de 132 y 6432.
Obtención del MCD original:
a) 6 + 8 = 14
b) 4 + 8 = 12
c) 2 + 8 = 6
d) 6 + 8 = 2
Con estos resultados, veamos cual de ellos es el MCD de 132 y 6432.
Para el 6432:
6432 / 2 = 3216
6432 / 6 = 1072
6432 / 12 = 536
6432 / 14 = 459,24
Podemos observar con estos resultados que el 14 queda descartado al tener un resultado decimal, por lo tanto debe ser 2, 6 o 12. Veamos la cuenta con el 132:
Para el 132:
132 / 2 = 66
132 / 6 = 22
132 / 12 = 11
Podemos observar ahora en este caso que el 132 es divisible entre 12, por lo tanto, es el MCD entre 132 y 6432, asi que se concluye que el resultado de disminuir por 8 el MCD de ambos números es:
12 - 8 = 4Exitos
Por definición de máximo común divisor,
MCDSe denomina máximo común divisor o MCD al mayor número que divide exactamente a dos o más números a la vez. Es decir, MCD de dos o más números es el mayor número que divide a todos de manera exacta.
En otras palabras, el máximo común divisor o MCD es la cifra más alta por la cual se puede dividir un conjunto de números, dando como resultado un número entero.
Recordar que un divisor puede definirse formalmente como aquel número que está contenido en otro de forma exacta una cantidad n de veces.
Cálculo de MCDPara calcular el máximo común divisor de dos o más números, en primer lugar se debe descomponer esos números en factores primos.
La descomposición de un número en factores primos es encontrar los números primos que se multiplican para formar ese número, recordando que los números primos son aquellos que solo se dividen por sí mismos y por 1.
El máximo común divisor se obtiene escogiendo solo los factores primos comunes a los números, elevados al menor exponente. Es decir, se debe elegir solo los factores comunes, y los que se repitan son elegidos elevados a la mínima potencia.
Este casoLa descomposición en factores primos es:
6432= 2⁵×3×67
132= 2²×3×11
Entonces, el MCD es calculado como:
MCD (6432, 132)= 2²×3
MCD (6432, 132)= 12
Por último, el máximo común divisor (MCD) de 6432 y 132 disminuye en 8, por lo que:
12 - 8= 4
En resumen, si el máximo común divisor (MCD) de 6432 y 132 disminuye en 8, entonces será igual a 4.

[tex](1/5k)^2=1/5^2*k^2[/tex]
[tex]1/25*k^2=\frac{k^2}{25}[/tex]
Answer: [tex]\frac{1}{25}k^2[/tex]
This is equivalent to [tex]\frac{k^2}{25}[/tex]
In decimal form, this is equivalent to 0.04k^2
==================================
Work Shown:
We have the two pieces 1/5 and k, all in the parenthesis being squared.
Square each piece
Squaring the piece 1/5 leads to (1/5)^2 = 1/25, since 5^2 = 25squaring the k value leads to k^2So overall, we end up with the answer [tex]\frac{1}{25}k^2[/tex] which is equivalent to saying [tex]\frac{k^2}{25}[/tex]
In decimal form, this is 0.04k^2 because 1/25 = 0.04

the 3rd side could be?
Smaller than 20 meters
O Larger than 13 meters
Between 13 meters & 21 meters
Larger than 21 meters
Answer:
Between 13 meters & 21 meters

Sum of two sides of a triangle must be greater than the third side and difference of two sides must be less than the third side.
Sum of two sides [tex]=17+4=21[/tex] meters
Difference of two sides [tex]=17-4=13[/tex] metres

A drawing of a surfboard in a catalog, it shows its length as 8 4/9 inches. Find the actual length of the surfboard if 1/3 inch length from the drawing corresponds to 3/8 foot of the actual surfboard.
Answer:
9.5 feets
Step-by-step explanation:
Length of drawing = 8 4/9 inches
Scale : 1/3 inch in drawing = 3/8 actual length
Length of drawing / drawing scale
8 4/9 = 76/9 inches
Number of 1/3 inches in total length of drawing :
76/9 ÷ 1/3
76/9 * 3 / 1
(76*3) /(9*1) = 228 /9 = 9 3/9 = 9 1/3
9 1/3 * 3/8 foot
(228 / 9) * (3 /8)
(228/3) * (1/ 8)
228 / 24
= 9.5 feet
Daniel filled 1/4 cup scoop 2 times with nuts for a recipe which size measuring cup could daniel have filed one time to have the same amount for the recipe.
Answer:
[tex]Size= \frac{1}{2}\ cup[/tex]
Step-by-step explanation:
Given
[tex]Size = \frac{1}{4}\ cup[/tex]
[tex]Scoop = 2[/tex]
Required
Determine the size of cup for 1 scoop
For two scoops, we have:
[tex]Recipe = \frac{1}{4}+ \frac{1}{4}[/tex]
Take LCM
[tex]Recipe = \frac{1+1}{4}[/tex]
[tex]Recipe = \frac{2}{4}[/tex]
[tex]Recipe = \frac{1}{2}[/tex]
This implies that, the amount of recipe is 1/2
If he uses a cup of size 1/2, he would only need 1 scoop.
Hence:
[tex]Size= \frac{1}{2}\ cup[/tex]

Alice's average mark for 4 Science exams is 68%. Can Alice score enough marks in a fifth exam so that her average mark increases to 75?%? Give reasons.
Answer:
It is not possible for Alice to score an average of 75% because what she needs to score in the fifth exam exceeds the maximum possible score.
Step-by-step explanation:
She scored an average 68% in all 4 exams.
This means; (68% + 68% + 68% + 68%)/4
Now, a fifth exam is added and we want to know if her average can now be 75%.
Thus, let the score in the 5th exam be x and we now have;
(68% + 68% + 68% + 68% + x)/5 = 75%
Multiply both sides by 5 to get;
(68% + 68% + 68% + 68% + x) = 375%
272% + x = 375%
x = 375% - 272%
x = 103%
The maximum score is 100% and therefore it is impossible for her to score 103%. Therefore it is not possible for Alice to score an average of 75%
