Answer:

Step-by-step explanation:

Use sine.

$sine=\dfrac{opposite}{hypotenuse}$

We have:

$opposite=x\\hypotenuse=16$

$\sin40^o\approx0.6428$ look at the table in the picture

Substitute:

$\dfrac{x}{16}=0.6428$ multiply both sides by 16

$x=10.2848\to x\approx10.3$

Which two expressions are equivalent?

MariettaO [177]

Answer:

First option

Step-by-step explanation:

The result of first expression:

7(6+z) multiply 7 with inside the parenthesis

7(6+z) = 42 + 7z

the result of second expression:

since we need to do multiplying first,

7*6 = 42 and 7*z = 7z

then we add them

42 + 7z this is the same result we found for the first equation

What is the volume of this solid? A. 1104 B. 132 C. 96 D. 276

statuscvo [17]

For this case we have that the volume of the figure is composed of the volume of a prism and the volume of a pyramid:

The volume of the prism is given by:

$V = A_ {b} * h$

Where:

$A_ {b}$ : It is the area of the base

h: It's the height

Substituting: $V = 6 * 6 * 6\\V = 216 \ units ^ 3$

The volume of the pyramid is given by:

$V = \frac {1} {3} * L ^ 2 * h$

Where:

$L ^ 2:$ It is the area of the base

h: It's the height

Substituting:

$V = \frac {1} {3} * 6 ^ 2 * 5\\V = \frac {1} {3} * 36 * 5\\V = 60units ^ 3$

We add and we have:

$V = 276 \ units ^ 3$
