Determine the scale factor for the following points: (4, 2) to (16, 8)

hammer [34]

Answer:

The rule of dilation by a scale factor 4 is:

(x, y) → (4x, 4y)

P(4, 2) → (4x, 4y) = (4(4), 4(2)) = P'(16, 8)

Therefore, 4 will be the scale factor.

Step-by-step explanation:

Given the point

(4, 2)

As the image coordinates of (4, 2) are (16, 8) after the scale factor, we need to determine what could be the scale factor.

Let P(4, 2) is the original point, and P'(16, 8) is the image of the point P(4, 2).

It is clear that the coordinates of the image P'(16, 8) are 4 times the coordinates of the original point P(4, 2), which means the point P(4, 2) is dilated by a scale factor of 4.

Thus, the rule of dilation by a scale factor 4 is:

(x, y) → (4x, 4y)

P(4, 2) → (4x, 4y) = (4(4), 4(2)) = P'(16, 8)

Therefore, 4 will be the scale factor.

Pls tell me how to do it.

kkurt [141]

Lets get started :)

The ratio of juice is as follows:
orange : mango : apple
3 : 5 : 4
↑
35 bottles

5x = 35

$\frac{5x}{5} = \frac{35}{5}$
5 and 5 cancels out
x = 7

3x + 5x + 4x = total
Subsitute the value you go for x, x = 7
3(7) + 5(7) + 4(7) = total
21 + 35 + 28 = 84

Total of 84 bottles of juices :)
Your final answer will be option D

Four consecutive multiples of 6 yield a sum of 156. What are these multiples?

olga nikolaevna [1]

Let x be the first number:
1st number: = x
2nd consecutive multiple of 6 = x+6
3rd consecutive multiple of 6 = x+12
4rth consecutive multiple of 6 = x+18
Their sum = 156 → x+(x+6)+(x+12)+(x+18) = 156
4x +30 = 156
4x = 120 and x = 30

The numbers are: 30,36,42,48

If the diameter is 15.5 cm what is the circumference

tresset_1 [31]

Answer:

see below

Step-by-step explanation:

The circumference is given by

C = pi *d

C = 15.5 pi

If we approximate pi by 3.14

C = 15.5 * 3.14

C =48.67

If we use the pi button

C =48.69486813
