A 25-foot long ladder is propped against a wall at an angle of 18° with the wall. Which diagram correctly represents this scenario? A ladder is propped against a 25 foot tall wall. The angle between the ladder and the ground is 18 degrees. A 25 foot ladder is propped against a wall forming an 18 degree angle. A ladder is propped against a wall forming an 18 degree angle. The distance between the bottom of the ladder and the wall is 25 feet. A 25 foot ladder is propped against a wall. The angle between the ladder and the ground is 18 degrees.

step-by-step explanation:

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)

did u ever get the answers? i need
