Please help me before 3pm est A deli sells small, medium, and large sack lunches. Each bottle of water costs $1,
and each apple costs $1. Each sandwich costs s dollars. Some customers buy
sack lunches, and some customers buy items separately.
• Amy buys 8 sandwiches and 12 waters. Her total cost is 8s + 12.
• Bob buys 8 small sack lunches. These sack lunches include 1 sandwich, 1
water, and 1 apple. His total cost is 8(s + 2).
• Cathy buys 4 medium sack lunches. These sack lunches do not include
water. Her total cost is 4(2s + 3).
Part 1
Dave buys 5 sandwiches for $31.25. Write an expression that can be used to find
the cost of x sandwiches. Show your work or explain your answer.

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

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

look at the picture i have filled out a table for it. hope this .

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
