Triangle A″B″C″ is formed using the translation (x + 1, y + 1) and the dilation by a scale factor of 3 from the origin. Which eq

FromTheMoon [43]

Answer:

$B''C''=3BC$

Step-by-step explanation:

we know that

The length of segment B''C'' is equal to the length of segment BC multiplied by the scale factor

step 1

Find the length of segment BC

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have the points

B(1,-3),C(-3,-3)

substitute the values

$BC=\sqrt{(-3+3)^{2}+(-3-1)^{2}}$

$BC=\sqrt{(0)^{2}+(-4)^{2}}$

$BC=4\ units$

The segment B''C'' is equal to the segment BC multiplied by the scale factor

The scale factor is 3

so

$B''C''=BC(3)$

$B''C''=3BC$

substitute

$B''C''=3(4)=12\ units$

4a. Riley is buying things for a holiday party that she is having. She wants to make a cheese and cracker appetizer; every crack

4a.

We can get the least number by taking LCM of 24 and 16.

We list each of the numbers as prime factors and take the mutiplication of each unique prime factor that occurs the greatest number of times.

24 = 2 * 2 * 2 * 3

16 = 2 * 2 * 2 * 2

So,

2 occurs four times

3 occurs 1 times

LCM of 24 and 16 is:

2 * 2 * 2 * 2 * 3 = 48

Least number of cheese and cracker appetizer = 48

4b.

Sleeves are sold in 24.

So, to get 48, she would need to buy:

48/24 = 2 sleeves

4c.

Cheese slices comes in packages of 16. So she needs to buy:

48/16 = 3 packages of cheese
