fgiga [73]

Here's the right way:

\dfrac{x}{\frac 3 5} = \dfrac{20}{12}

x = \dfrac{20}{12} \cdot \dfrac{3}{5} = 1

Here's the way they want you to do it:

\dfrac{x}{\frac 3 5} = \dfrac{20}{12}

12 x = 20 \times \dfrac{3}{5} = 12 \textrm{ FIRST BOX}

x = 12/12 = 1 \textrm{ SECOND BOX}

Given each of the following areas, what would be the radius of each circle? a. A = 530.66 m2 b. A = 907.46 sq. ft. c. A = 379.94
ra1l [238]
Area for a circle is A= \pi r^2.  We will fill in each area and then solve for the radius.  530.66m^2= \pi r^2 and \frac{530.66m^2}{3.14}=r^2.  ∴169=r^2 and r = 13.  For b, 907.46ft^2= \pi r^2 and \frac{907.46ft^2}{3.14}=r^2.  289=r^2, ∴ r = 17.  For c, 379.94mi^2= \pi r^2, and \frac{379.94mi^2}{3.14}=r^2.  ∴, 121=r^2 and r = 11.  For d, 1962.5cm^2= \pi r^2, and \frac{1962.5cm^2}{3.14}=r^2.  ∴, 625=r^2 so r = 25.  And there you have it!

PtichkaEL [24]

Answer:

  • $9 and $7

Step-by-step explanation:

<u>The first equation:</u>

  • x + 2y = 23

<u>The second equation:</u>

  • 2x + 3y = 39

<u>Convert to slope-intercept form:</u>

  • x + 2y = 23 ⇒ 2y = -x + 23 ⇒ y = -1/2x + 11.5
  • 2x + 3y = 39 ⇒ 3y = -2x + 39 ⇒ y = -2/3x + 13

<em>The graph is attached</em>

<u>Intersection point is (9, 7)</u>
