Let

A( 5.0,2.8) B( -2.8,5.1)

we know that

The formula to find the distance between two points is equal to

d=\sqrt{(y2-y1)^{2} +(x2-x1)^{2}}

substitute in the formula

d=\sqrt{(5.1-2.8)^{2} +(-2.8-5)^{2}}

d=\sqrt{(2.3)^{2} +(-7.8)^{2}}

d=\sqrt{66.13}

d=8.13\ cm

therefore

<u>the answer is</u>

the distance between these points is 8.13\ cm

Ksivusya [100]

Answer:

1.96 smaller pizzas can fit into the larger pizza.

Step-by-step explanation:

Area of smaller pizza:

π × (10/2)^2 = π × 5^2 = 25π square inches

Area of larger pizza:

π × (14/2)^2 = π × 7^2 = 49π square inches

Ratio of area of larger pizza to area of smaller pizza: 49π / 25π = 1.96

a cargo ship arrived at Kingston Harbour carrying 403,172 kilograms of flour. All the flour was tranfered to 5 trains and 9 truc
IrinaVladis [17]

Each train carried 64141 kg of flour and each truck carried 9163 kg of flour.

Step-by-step explanation:

Let the no. of kg of flour carried by each train be 'a'

Let the no. of kg of flour carried by each truck be 'b'

Total flour = 403172 kg

No. Of trains = 5

No. of trucks = 9

a = 7(b)

5a + 9b = 403172

5(7b) + 9b = 403172

35b + 9b = 403172

44b = 403172

b = 403172/44

b = 9163

Each truck carried 9163 kg of flour.

a = 7b

a = 7(9163)

a = 64141

Each train carried 64141 kg of flour.
