Casey is completing an experiment that requires 300 ml of potassium chloride (kcl) at a concentration of 0.2 m. but casey's lab only stores potassium chloride at concentrations of 0.1 m and 0.5 m. how much 0.1 m kcl will casey have to mix with 0.5 m kcl to make 300 ml of 0.2 m kcl?

i am currently in the exact same situation rn. algebra2/adv algebra is killing

step-by-step explanation:

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
