Dan spends 2 5 of his wages on rent and 1 2 on food. If he makes ?430 per week, how much money does he have left?

BartSMP [9]

Answer:

Dan would be left over with $43 a week.

Step-by-step explanation:

$\frac{2}{5}$ = 40%

$\frac{1}{2}$ = 50%

Rent: $430 - 40% = $172

Food: $430 - 50% = $215

$215 + $172 = $387

$430 - $387 = $43

Find the distance between the two points (-10,3) and (0,27)

crimeas [40]

Answer:

26 units

Step-by-step explanation:

$\boxed{distance \: between \: 2 \: points = \sqrt{ {(x1 - x2)}^{2} + {(y1 - y2)}^{2} } }$

Using the formula above,

distance between (-10, 3) and (0, 27)

$= \sqrt{ {( - 10 - 0)}^{2} + {(3 - 27)}^{2} }$

$= \sqrt{ {10}^{2} + ( - 24) {}^{2} }$

$= \sqrt{100 + 576}$

$= \sqrt{676}$

= 26 units
