Find the distance between the two points rounding to the nearest tenth (if necessary).

iris [78.8K]

Step-by-step explanation:

Distance between (−3,6) and (−9,−2):

$(x_1, y_1)$

= coordinates of the first point

= (-3,6)

$(x_2, y_2)$

= coordinates of the second point

= (-9,-2)

$d = \sqrt{(x_2 - {x _1) }^{2} + (y_2 - {y _1) }^{2}}$

$d = \sqrt{ (- 9 - ( - 3) {)}^{2} + ( - 2 + 6 {)}^{2} }$

$d \: = \sqrt{ (- 6 {)}^{2} +( 4 {)}^{2} }$

$d = \sqrt{36 + 16}$

$d = \sqrt{52}$

$d = \sqrt{13 \times 2 \times 2}$

$d = 2 \sqrt{13}$

Carol is sixty-two inches tall. This is twenty inches less than two times Mindy's height. How tall is Mindy?

choli [55]

You would add 20 to 62= 82. Then divide that by 2 to get Mindys height. Mindy is 41 inches tall. :)

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
