Hiro painted his room. After 3 hours of painting at a rate of 8 square meters per hour, he had 28 square meters left to paint.

Let y represent the area (in square meters) left to paint after xxx hours.

Which of the following information about the graph of the relationship is given?
A
Slope and xxx-intercept

(Choice B)

B

Slope and yyy-intercept

(Choice C)

C

Slope and a point that is not an intercept

(Choice D)

D

xxx-intercept and yyy-intercept

(Choice E)

E

yyy-intercept and a point that is not an intercept

(Choice F)

F

Two points that are not intercepts

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
