(B) Talia is correct. The lateral area can be found by approximating one large triangle, which can be found using the expression 4 (one-half (8) (6.9))

Step-by-step explanation:

Base of the Pyramid = 8 Inches

Height of the Triangular Face = 6.9 Inches

In any solid shape, the Lateral surface area is the sum of all sides except its top and bottom bases.

Since the four triangles are congruent:

Lateral Surface Area = 4 X Area of One Triangle

Area of a Triangle = $\frac{1}{2}$ X Base X Height$

Area of one Triangular Face $= \dfrac{1}{2}(8)(6.9)$

Therefore:

Lateral Surface Area $= 4\left(\dfrac{1}{2}(8)(6.9)\right)$

Therefore, Talia is correct.

Fernando bought 8 pints of milk. How many fluid ounces of milk did Fernando buy?

nordsb [41]

Answer: 128 fluid ounces

Step-by-step explanation:

First and foremost, we need to realize that:

1 pint = 16 ounces

Therefore, since Fernando bought 8 pints of milk, to convert it to ounces, we just have to multiply 16 by 8. This will be:

= 16 ounces × 8

= 128 ounces

What is the exact value of cos 45° ?

Georgia [21]

Let the two sides of a right triangle be equal to one, which means that the hypotenuse is √2

Since cosa=adjacent side / hypotenuse

cos45=1/√2

We can rationalize the denominator by multiplying numerator and denominator by √2

√(2)/2

or if you prefer: √(1/2)
