Contact [7]3 years ago
4 0

answer:

70/100x = 63

step-by-step explanation:

so first we must turn 70% into a fraction-

70/100

and since we know that 63 is the answer

that must mean that x is being multiplied by 70/100

therefore making the equation 70/100x=63

good luck :)

i hope this helps

brainliest would be highly appreciated

have a nice day!

The area of the house is the amount of space on the house.

  • The length of the addition is x + 20
  • The area of the original house is x^2 + 30x + 200

<h3>The length of the addition</h3>

The area of the addition is given as:

Area = x^2 + 10x - 200

Expand

Area = x^2 + 20x - 10x - 200

Factorize

Area = x(x + 20) - 10(x + 20)

Factor out x + 20

Area = (x -10)(x + 20)

The width of the addition is x - 10.

Hence, the length of the addition is x + 20

<h3>The area of the original house</h3>

The dimension of the original house is

x + 20 by x + 10

So, the area is:

Area =(x + 20)(x + 10)

Expand

Area =x^2 + 20x + 10x + 200

This gives

Area =x^2 + 30x + 200

Hence, the area of the original house is x^2 + 30x + 200

Answer:

? = 13.6

Step-by-step explanation:

the angle between a tangent and the diameter = 90°

Then the triangle is right with legs 2 × 6 = 12 and 6.4

using Pythagoras' identity in the right triangle.

the square on the hypotenuse is equal to the sum of the squares on the legs , that is

? ² = 12² + 6.4² = 144 + 40.96 = 184.96 ( take square root of both sides )

? = \sqrt{184.96} = 13.6

Step-by-step explanation:

distance = \sqrt{(8-9)^{2} +(3-0)^{2} }

=\sqrt{1^{2}  +3^{2} }

=\sqrt{1+9}

=\sqrt{10}

=3.16
