PLease somebody help me

y = 0.35x

Step-by-step explanation:

Jane:

Cost of 3 postcards= $1.05

Cost of 1 post card = 1.05 ÷ 3

                              = $ 0.35

Rosi:

Cost of 5 postcards= $1.75

Cost of 1 post card = 1.75 ÷ 5

                              = $ 0.35

Tanya:

Cost of 8 postcards= $2.80

Cost of 1 post card = 2.80 ÷ 8

                              = $ 0.35

As unit rate is same, Cost and number of postcards are in proportion.

Cost of cards = 0.35 * number of cards

y = 0.35*x

y = 0.35x

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.
