Suppose the original price to be x.
62%x=296.4
Divide both sides by 62% to get x=478, which is the original price.

Are the expressions x + x + 1 + x + 2 + x + 1 + x and 5x + 4 equivalent? Why or why not?

egoroff_w [7]

Answer:

yes

they are equivalent because lets say the X = 3 then you would have to answer

3 + 3 + 1 + 3 + 2 + 3 + 1 + 3

and that would = 19

and then on the other equation

5 x 3 + 4 = 19

So the both equal the same.

tekilochka [14]

Irrational numbers are numbers that can not be written as a simple fraction. An example of one would be $\pi$ . Pi is about 3.14, but it goes on forever. You can not write pi as a simple fraction.

An architectural firm wants to replicate a nearby estate with some changes. The new estate will be larger than the original by a

Oduvanchick [21]

Answer:

Option B.

Step-by-step explanation:

It is given that the new estate will be larger than the original by a scale factor of 1:10.

A section of the roof in the original estate is constructed using 45-45-90 triangles. The hypotenuse of the triangle is 10 meters long.

Two angles are equal and one angle is a right angle, it means it is an isosceles right-angled triangle.

Let $x$ be the length of the legs of the triangle for the larger estate.

The hypotenuse of larger estate = 10 × 10 = 100

Using Pythagoras triangle,

$perpendicular^2+base^2=hypotenuse^2$

$x^2+x^2=(100)^2$

$2x^2=10000$

Divide both sides by 2.

$x^2=5000$

Taking square root on both sides.

$x=\sqrt{5000}$

$x=70.71\text{ meters}$

Hence, the correct option is B.
