Answer:

C

Step-by-step explanation:

If a line is parallel to a side of a triangle and it intersects the other 2 sides then it divides those sides proportionally.

BE is such a line , then

\frac{AE}{ED} = \frac{AB}{BC} ( substitute values )

\frac{9}{5} = \frac{9.2}{BC} ( cross- multiply )

9 BC = 46 ( divide both sides by 9 )

BC ≈ 5.1 ( to the nearest tenth )

Then

AC = AB + BC = 9.2 + 5.1 = 14.3

The area of a rectangular parking lot is 4947 m2.
Sedbober [7]

Answer:

1. width = 51 m

2. length = 84 m

Step-by-step explanation:

So remember, the area is (length * width).

It is given that the length is 97, and the area is 4947.

So plug this into a formula:

length * width = area

97 * width = 4947

Solve using inverse operations;

97 * width = 4947

/97               /97

width = 51m

The perimeter of a rectangle can be found by doing, (2 * (length + width)).

The width is given, it is 68m. The perimeter is also given, 304m. So just form an equation using this information:

2 * ( length + width) = perimeter

2 * (length + 68 ) = 304

Distribute;

2 * ( length + 68) = 304

2 length + 136 = 304

Inverse operations;

2length + 136 = 304

               -136    -136

2length = 168

/2             /2

length = 84m

A river 3m deep and 40 m wide is flowing at the rate 2km /h . how much water will fall into the sea in a minute.​
Alex

Answer:

Area of river = 3 × 40

= 120 {m}^{2}

amount of water that falls into the sea ⇒

= Area × rate

= 120 × 2 \frac{km}{hr}

= 120× \frac{2000  m}{60  min}

= 2 × 2000

= 4000 m  ^{3}

∴4000m  ^{3} of water falls into the sea permin.

Step-by-step explanation:
