in a long jump competition, peter jumped 0.13 m further than roy. sam jumped
0.27 shorter than peter. the three boys jumped a total distance of 4.34 m. how far
did sam jump?
si

Sam jumped 1.31 m

Step-by-step explanation:

We can start by writing a system of equations.

Peter = Roy + 0.13

Sam = Peter - 0.27

Peter + Roy + Sam = 4.34

Then, we can rewrite the equations so that we have them in term of Peter, p.

Peter- p = p

Roy- r = p - 0.13

Sam- s = p - 0.27

Now, we can plug this into the equation

s + p + r = 4.34.

Take out the parentheses

Combine liketerms.

Add 0.4 to both sides.

Divide both sides by 3.

Now, we can plug that into Sam's equation.

may i see the picture? it would a lot, xox

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
