Answer:

A=17.99\ in^2

Step-by-step explanation:

Given that,

A triangle with side lengths 6 inches, 6 inches, and 8.5 inches.

We need to find the area of the cloth.

The side lengths form an isosceles triangle. The formula for the area of the isosceles triangle is given by :

A=\dfrac{1}{2}\times b\times h

Where

h=\sqrt{a^2-\dfrac{b^2}{4}}

So,

A=\dfrac{1}{2}\times b\times \sqrt{a^2-\dfrac{b^2}{4}}

Put a = 6 and b = 8.5

So,

A=\dfrac{1}{2}\times 8.5\times \sqrt{6^2-\dfrac{8.5^2}{4}}\\\\A=17.99\ in^2

So, the area of the cloth is equal to 17.99\ in^2.

Which product is modeled by the number line below?
Gnoma [55]

Answer:

(B)(negative 2) (4)

Step-by-step explanation:

The arrow on the number line ended at negative 8 (-8).

Given the options:

(A) (negative 3) (4) =(-3)(4)=-12

(B)(negative 2) (4) =(-2)(4)=-8

(C) (2)(4)=8

(D)(3)(4)=12

The expected product is -8 since that is where the arrow ended. Therefore, the product that is modeled by the number line is that which gives a result of -8. The correct option is B.

(B)(negative 2) (4) =(-2)(4)=-8
