Marcus is making cookies. the recipe says 2 1/4 cups of flour are needed for each batch. marcus wants to make 3 batches of cookies.

how many cups of flour will marcus use?

3/4 cups

1 1/3 cups

5 1/4 cups

6 3/4 cups

6 3/4

Step-by-step explanation:

Multiply 2.25 with 3: 2.25 · 3 = 6.75 = 6 3/4

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.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
