Iwill give ! what is the volume of a sphere with a diameter of 14 centimeters? use 3.14 for pi. round your answer to the nearest hundredth. (4 points) select one: a. 1077.02 cm3 b. 1436.03 cm3 c. 1975.43 cm3 d. 11,494.04 cm3

bearing in mind that, if the diameter is 14, then its radius is half that, or 7.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

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)
