a=10, c=1.4

Step-by-step explanation:

so the ratio of the side with the length 5 to the side a is 1:2(or we could say a to 2a). Because of this we now multiply 2 to 5 to get a=10(because it is a 1 to 2 ratio).The relation between the side worth 2 and the side c is a√2 to a. so we divide √2 from 2 to get √2 and this number in decimal form is 1.41421356237, so rounded to the nearest tenth is 1.4(because 1 rounds down)

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
