Area circle = 50.27 (50)

Area square = 32.3 (32)

Area circle minus area square = 50.27-32.3= 17.97 (18)

18/50 = 9/25 = 0.36

AnnZ [28]

Answer:

Step-by-step explanation:

Divide 50 by 2/3. Division is the same as asking "how many times can i subtract 2/3 from 59?"

$50 \div \frac{2}{3}$

Dividing by a fraction is the same as multiplying by the reciprocal.

$50 \times \frac{3}{2} = 75$

You can subtract 2/3 from 50, 75 times

A small craft in lake Ontario sends out a distances signal. The coordinates of the boat in trouble are (57,64). One rescue boat

KatRina [158]

Answer:

The coast guard craft will get to the distressed boat the fastest.

Step-by-step explanation:

The coordinates of boat are (57,64).

The coordinates of rescue boat are (67,83).

The coordinates of coast guard craft are (65,46).

Both rescue crafts travel at the same rate. One of them will get to the distressed boat the faster, whose distance from the boat is least.

Distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

The distance between boat and rescue boat is

$d_1=\sqrt{(67-57)^2+(83-64)^2}=21.4709105536\approx 21.47$

The distance between boat and coast guard craft is

$d_2=\sqrt{(65-57)^2+(46-64)^2}=19.6977156036\approx 19.70$

Since the distance between boat and coast guard craft is least, therefore coast guard craft will get to the distressed boat the fastest.
