The expression that lists all numbers in prime numbers would be A. All numbers here are prime numbers, and is in the simplified form, the remaining choices are not in their simplified forms and can be broken down into smaller numbers that multiply to give their value.

What is unit price ? Use in your own words . ​
dezoksy [38]

Unit price means the cost per unit.

I'll provide an example.

If 4 bars of soap cost $2.35, find the unit price. Round to the nearest cent if necessary.

Remember that the unit price is the cost per unit which in this case is the cost per bar of soap. Since $2.35 is the cost for 4 bars of soap, to find the cost per bar of soap, we divide 4 into $2.35.

When we do this, we get an answer of 0.587 which rounds up to 59 cents.

Therefore, the unit price for soap is 59 cents.

A circle has circumference 27 cm. What is the area of the circle? Use 3.14 for .
ella [17]

Circumference = 2πr = 27 cm

= 2 × 3.14 × r = 27

= 3.14 × r = 27/2

so, r = \frac{27}{2} × \frac{1}{3.14} = 4.2 cm

       What is the equation of the line that passes through (-3, 6) and has a slope of -2?

\diamond\large\blue\textsf{\textbf{\underline{\underline{Answer and how to solve:-}}}}\diamond

     

First, we need to write the equation of the line in point-slope form:-

\sf{y-y_1=m(x-x_1)}

Replace y1 with 6, m with -2, and x1 with -3:-

\sf{y-6=-2(x-(-3)}

On simplification,

\sf{y-6=-2(x+3)}

On further simplification,

\sf{y-6=-2x-6}

Add 6 on both sides:-

\it{y=-2x}

<h3>Good luck with your studies.</h3>
