Evaluate (491) square in the form of (a-b) square
Tomtit [17]

Step-by-step explanation:

(491)^{2}  \\  \\  = (500 - 9)^{2}  \\  \\  = ( {500})^{2}  - 2 \times 500 \times 9 + ( {9})^{2}  \\  \\  = 250000 - 9000 + 81 \\  \\  = 16000 + 81 \\  \\  = 16081 \\  \\    \huge\purple{ \boxed{\therefore (491)^{2}= 16081}}

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.

The area of the rectangular floor in Tamara’s room is 9556 square feet. The width of the room is 813 feet. Part A Round each mea
denis23 [38]

Answer:

Area of Tamara room

=9556 square feet

Width

=813 feet

Length= 11.75 feet

Total area= 19794 square feet

480 square feet will not be enough

Step-by-step explanation:

Dimensions of Tamara's room to the nearest whole numbers

Area of Tamara room

=9556 square feet

Width

=813 feet

For the length

Length*width= area

Length= area/width

Length= 9556/813

Length= 11.75

To the nearest whole number = 12 feet

The ceiling is 12 feet high

Let's calculate for the area of the combination

1)Height and width two times

2)Height and length two times

1).area = 12*813

= 9756

Then 9756*2= 19512

2). area= 12*11.75

= 141

Then 141*2= 282

Total area = 282+19512

Total area= 19794
