the volume of a rectangular pyramid is 1.32 cubic inches. the height of the pyramid is 1.1 inches and the length of the base is

worty [1.4K]

Work:

V = l × w × h

1.32 = 1.2 × w × 1.1

1.32 = 1.32 × w

1.32 ÷ 1.32 = 1

Answer:

1 inch = width

<em>Correct Question:</em>

<em>Type the correct answer in the box. Use numerals instead of words. Consider this expression. </em> $\sqrt{a^2} - 7 + |b|$ <em> </em><em> When a = 2 and b = -4, the value of the expression is</em>

Answer:

$\sqrt{a^2} - 7 + |b| = -1$

Step-by-step explanation:

Given

$a=2$

$b = -4$

Required

Determine $\sqrt{a^2} - 7 + |b|$

To solve this, we simply substitute the values of a in the given expression

$\sqrt{a^2} - 7 + |b|$

$\sqrt{a^2} - 7 + |b| = \sqrt{2^2} - 7 + |-4|$

Express 2² as 4

$\sqrt{a^2} - 7 + |b| = \sqrt{4} - 7 + |-4|$

Express square root of 4 as 2

$\sqrt{a^2} - 7 + |b| = 2 - 7 + |-4|$

$|-4| = 4$

So, we have

$\sqrt{a^2} - 7 + |b| = 2 - 7 + 4$

$\sqrt{a^2} - 7 + |b| = -1$

<em>Hence, the result of the expression is -1</em>
