Evaluate the expression 42+6⋅52−33÷32
mote1985 [20]
The first step to solve this is to multiply the numbers
42 + 312 - 33 ÷ 32 
then divide the numbers
42 + 312 - 1.03125
use the addition and subtraction rules to calculate the expression
352.96875
this means that the correct answer to your question will be 352.96875.

A rectangular field is two times as long as it is wide. If the perimeter of the field is 450 feet, what are the dimensions of th
lys-0071 [83]

Hi There,

----------------------------------------

We Know:

Total Perimeter = 450 feet

Length is 2 times the width.

----------------------------------------

Solution:

Length = 150

Width = 75

75 x 2 = 150

150 + 150 + 75 + 75 = 450

----------------------------------------

Answer:

Length = 150 feet.

Width = 75 feet.

----------------------------------------

Hope This Helps :)

Use the graph of △ABC with midsegments DE, EF and DF. Show that EF is parallel to AC and that EF=1/2 AC
Vinvika [58]

According to the midsegment theorem, the midsegments are parallel to

and half the length of the opposite side.

The completed statement are as follows;

  • Because the slopes of \overline{EF} and \overline{AC} are both<u> -4</u>, \overline{EF} ║ \overline{AC}
  • EF = \underline{\sqrt{17}} and AC = \underline{2 \cdot \sqrt{17} }
  • Because \underline{\sqrt{17} } = \underline{\frac{1}{2} \cdot 2 \cdot \sqrt{17} }, EF = \frac{1}{2} \cdot AC

<u />

Reasons:

From the given graph of ΔABC, we have;

Coordinates of the points <em>A</em>, <em>B</em>, and <em>C </em>are; A(-5, 2), B(1, -2), and C(-3, -6)

The coordinates of the point D and E on \mathbf{\overline{DE}} are; D(-4, -2), and E(-2, 0)

The coordinates of the point F is; F(-1, -4)

  • Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}

\displaystyle Slope \ of \ line \ \overline{AC} = \mathbf{\frac{(-6) - 2}{-3 - (-5)}  = \frac{-8}{2}} = -4

\displaystyle Slope \ of \ line \ \overline{EF} = \frac{0 - (-4)}{-2 - (-1)}  = \frac{4}{-1} = -4

  • Length \ of \ segment,\ l = \sqrt{\left (x_{2}-x_{1}  \right )^{2}+\left (y_{2}-y_{1}  \right )^{2}}

Length of EF  = √((-1 - (-2))² + (-4 - 0)²) = √(17)

Length of AC = √((-3 - (-5))² + (-6 - 2)²) = √(4 × 17) = 2·√(17)

Therefore, we have;

Because the slope of \mathbf{\overline {EF}} and \mathbf{\overline {AC}} are both , <u>-4</u>, \overline {EF} ║ \overline {AC}. EF = \underline{\sqrt{17}}, and AC

= \underline{\frac{1}{2} \cdot 2 \cdot \sqrt{17}},. Because \underline{\sqrt{17}} = \underline{\frac{1}{2} \cdot 2 \cdot \sqrt{17}}, EF =\mathbf{ \frac{1}{2} AC}
