ivan scores 56 out of 80 marks in a maths test
what is his score as a percentage

F. Square root of 39

Step-by-step explanation:

Value of [tex]\boldsymbol{x}[/tex] is [tex]\boldsymbol{\sqrt{39}}[/tex] units.

Option F. is correct.

Two triangles are said to be similar if their sides are proportional and their corresponding angles are equal.

[tex]\bigtriangleup ABD \sim \bigtriangleup CAD[/tex]

[tex]\boldsymbol{\frac{AD}{CD}=\frac{BD}{AD} }[/tex]

  [tex]\frac{x}{13}=\frac{3}{x}[/tex]

  [tex]x^2=39[/tex]

   [tex]x=\sqrt{39}[/tex] units.

Value of [tex]\boldsymbol{x}[/tex] is [tex]\boldsymbol{\sqrt{39}}[/tex] units.

Option F. is correct.

Answer:

Step-by-step explanation:

a)  

4x - 3 = 2x + 7

4x - 2x = 7 + 3

2x = 10

x = 10 / 2

x = 5

b)

2x + 6 = 7x - 14

6 + 14 = 7x - 2x

20 = 5x

x = 20 / 5

x = 4

Answer:

7

Step-by-step explanation:

Answer:

x = 13

Step-by-step explanation:

x = hypotenuse which is c in the Pythagorean theorem

c = √a^2 + b^2

c = √12^2 + 5^2

c = 13

Answer:

Vertical change= 1

Horizontal change= 2

Rate of change=  1/2

Step-by-step explanation:

The vertical change is how many units you go up on the triangle and the horizontal change is how many units you go left or right on the triangle. The rate of change is the vertical change over the horizontal change. So that is why 1/2 is the rate of change. Have a great day!

2[tex]x^3[/tex] - 7[tex]x^2[/tex] + 8x -3

Step-by-step explanation:

To multiply a binomial (2 terms) by a trinomial (3 terms):

Multiply the first term of the binomial by the each term of the trinomial.

Multiply the second term of the binomial by each term of the trinomial.

Combine the expressions and simplify.

(2x-3)*([tex]x^2[/tex]-2x+1)

(2x * [tex]x^2[/tex]) + (2x * -2x) + (2x * 1)

Answer:

0.0576 ft2

Step-by-step explanation:

If the scale factor between a front door's blueprint and the actual front door is 0,04 The front door's actual area is 36 ft2, while its area on the blueprint will be 1.44 ft².

The ratio among comparable dimensions of an object and a model with that object is known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.

It is given that, the scale factor of the blueprint of a front door to the actual front door is 0.04. The area of the actual front door is 36 ft².

Scale factor =Area of the new shape ÷ Area of the original shape

0.04= Area of the front door on the blueprint÷36 ft²

Area of the front door on the blueprint=0.04×36

Area of the front door on the blueprint=1.44 ft²

Thus, if the scale factor between a front door's blueprint and the actual front door is 0,04 The front door's actual area is 36 ft2, while its area on the blueprint will be 1.44 ft².
