Drag each tile to the correct box. label each statement with its corresponding type of scientific knowledge. law theory fact hypothesis the melting point of ice is 0°c. arrowright repeated observations have consistently shown that oppositely charged objects attract each other. arrowright when the elements carbon and nitrogen are mixed at 1500°c, they will react with each other. arrowright atoms are made of protons, neutrons, and electrons. although we can’t directly see these particles, this structure explains many experimental observations.

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60

sorry

step-by-step explanation:

sorry, but im pretty sure its a now that i look at it

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)

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
