Briyana has $150, and she needs to save at least
$560 for a spring break trip. if she can save $45
per week, how long will it take her to save enough
money?
let w = weeks saving money. write an inequality
to describe the situation.

150+45w≥560

Step-by-step explanation:

she already has 150 dollars so you add that to the amount she will earn per week she earns 45 dollars per week or 45w she needs at least 560 dollars so she needs to earn greater than or equal to 560 dollars by solving this problem you know she needs to work 10 hours or more

ok

step-by-step explanation:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
