Answer:

  • True, True, False, False, True

Step-by-step explanation:

Trapezoid ABCD was dilated to create trapezoid A'B'C'D'.

Scale factor is 1/2 according to the coordinates.

<h3>The answer options</h3>

<u>The length of side AD is 8 units.</u>

  • AD = 4 - (-4) = 8
  • True

<u>The length of side A'D' is 4 units.</u>

  • A'D' = 2 - (-2) = 4
  • True

<u>The image is larger than the pre-image.</u>

  • False. It is 2 times smaller.

<u>Sides CD and C'D' both have the same slope, 2.</u>

Slopes of CD and C'D' are same: m = (0 - 4)/(4 - 2) = -4/2 = -2

  • False

<u>The scale factor is One-half.</u>

  • True

A 55m and 35m broad park is surrounded by a 2.5m wide path.
daser333 [38]

Step-by-step explanation:

☄ \underline {\underline{ \text{Given}}} :

  • Length of a park ( l ) = 55 m
  • Breadth of a park ( b ) = 35 m
  • Width running outside the park ( d ) = 2.5 m
  • Rate of paving the path with stones = Rs 120 per sq.metre

☄ \underline{ \underline{ \text{To \: find}}}:

  • Area of the park
  • Cosy of paving the path with stones at Rs 130 per sq.metre

☄ \underline{ \underline{ \text{Solution}}} :

Part 1 : \boxed{\text{Area \:of \:a \:path \: running \:outside = 2d(l + b + 2d)}}

plug the known values and simplify :

⟹ \sf{2 \times 2.5(55 + 35 + 2 \times 2.5)}

⟹ \sf{5  \times 95}

⟹ \sf{475 \:  {m}^{2} }

Part 2 : \boxed{ \sf{Total \: cost = Area \: of \: paths \:  \times  Rate}}

⟹ \sf{475  \times 120}

⟹\sf{Rs \: 57000}

\purple{ \boxed{ \boxed{ \sf{ \tt{⟿ \: Our \: final \: answer : (i) = 475 \:  {m}^{2}   \:  and \: (ii ) = Rs \: 57000}}}}}

Hope I helped ! ♡

Have a wonderful day /night ツ

a car can travel 476 miles on 14 gallons of gas. Write an equation relating the distance d to the number of gallon g. How many g
ch4aika [34]

miles per gallon (x) = d/g

x = 476/14 = x = 34 miles per gallon

so d/x = g

578/34 = 17 gallons are needed
