each music class sings 8 songs a week. how many songs does each class sing in 5 weeks? 6 weeks? 7 weeks?

Dvinal [7]

The correct answers are:

40 songs;

48 songs; and

56 songs.

Explanation:

Since each class sings 8 songs per week, to find the number of songs for any given number of weeks, we multiply:

8 songs per week * 5 weeks = 40 songs

8 songs per week * 6 weeks = 48 songs

8 songs per week * 7 weeks = 56 songs

Triangle HJK is transformed to similar triangle H’J’K’: A coordinate plane is shown. Triangle HJK has vertices H at 8 comma 8, J

Serggg [28]

We are given coordiates of vertices of triangle ΔHJK as H(8,8), J(8,4), K(4,4)

and coordinates of transformed triangle ΔH’J’K are H'(2,2), J'(2,1), k'(1,1).

We can clealry see that if we divide each value in coordinate by 4, we get the coordinates of the transformed triangle.

Let's see, what's dilation being applied there : H(8,8) ---> 1/4 (8,8) = H' (2,2) ,

J(8,4) ---> 1/4(8,4) = J'(2,1) and

K(4,1) ---> 1/4 (4,4) = K'(1,1).

So, we can clearly see that each coordinate is being multiplied by 1/4.

So, we can say the scale factor of dilation is 1 over 4, that is 1/4.

Y is inversely proportional to X. When y 20, x = 2 Work out y when x = 5

Oliga [24]

Answer:

When x = 5, y = 8.

Step-by-step explanation:

y is inversely proportional to X.

This means that we solve this using the rule of three for inversely proportional variables, that is, we apply line multiplication instead of cross multiplication.

y = 20, x = 2

Work out y when x = 5

20 - 2

x - 5

Applying line multiplication

$5y = 40$

$y = \frac{40}{5}$

$y = 8$

When x = 5, y = 8.
