cupcakes pastries
7 2
21 6
42 8
84 10

cupcakes pastries
7 2
21 6
28 12
35 24

cupcakes pastries
7 2
21 17
42 38
84 80

cupcakes pastries
7 2
14 4
28 8
56 16

Option D is the correct choice.

Step-by-step explanation:

We have been given that the ratio of the number of cupcakes to the number of pastries in a box is 7:2. We are asked to choose the table which represents the possible amounts of cupcakes and pastries in a box, given the ratio.

We can see that the ration in first three tables are not equal.

The amounts of cupcakes and pastries in a the 4th table are in the same ratio as:

Therefore, last table is the correct choice.

step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
