a rectangle has a length of x3y4 inches and a width of xy7 inches . Which expression represents the ratio of the length of the r
Oxana [17]

Answer:

A. x²/y³

Step-by-step explanation:

Given the following data;

Length = x³y⁴

Width = xy^{7}

Ratio = length/width

Ratio = \frac{x^{3}y^{4}}{xy{^7}}

Simplifying the equation by applying the law of indices (division), we have;

\frac{x^{3}}{x} = x^{3} - x^{1} = x^{3-1} = x^{2}

\frac{y^{4}}{y^{7}} = y^{4} - y^{7} = y^{4-7} = y^{-3}

Hence, rearranging the above values;

Ratio = \frac{x^{2}}{y^{3}}

<em>Therefore, the expression that represents the ratio of the length of the rectangle to the width of the rectangle is A. x²/y³. </em>

Somebody please prove if a triangle with side length of 6,8,10 is a right triangle using the Pythagorean theorem!! Will mark Bra
BabaBlast [244]
Answer:
Pythagorean’s theorem states that if a^2 + b^2 = c^2 where c is the hypotenuse and a and b are the side lengths of the right triangle

Given that we can plug in
a= 6 , b = 8 , c = 10

We get an equation:

6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100

Black_prince [1.1K]

Answer:

x = 11

Step-by-step explanation:

Using Secants ad Segments Theorem we can say;

(x + 7) (7) = (15 + 6) (6)

7x + 49 = (21) (6)

7x + 49 = 126

7x = 77

x = 11

Hope this helps!
