The length of a line is y centimetres write down an expression in terms of y for the length of the line in millimeters

10y

Step-by-step explanation:

First and foremost, we should note that: 1 centimeter = 10 millimeters.

Since the length of the line is y centimetres, the expression in terms of y for the length of the line in millimeter will be:

= y × 10

= 10y

For example, if the length is 3cm, it'll then be: = 10y = 10 × 3 = 30 millimeter

250

step-by-step explanation:

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
