Which of the following expressions are equivalent to -0.5(1.7+1.7)−0.5(1.7+1.7)minus, 0, point, 5, left parenthesis, 1, point, 7

Allisa [31]

The expressions equivalent to -0.5(1.7+1.7) are -0.5(1.7) - 0.5(1.7)

and 2(-0.5(1.7))

<h3>Distributive law of expansion</h3>

Given the expression below;

-0.5 (1.7 + 1.7)

According to the distributive law;

A(B+C) = AB + AC

Expand

-0.5(1.7) + (-0.5)(1.7)

-0.5(1.7) - 0.5(1.7)

2(-0.5(1.7))

Hence the expressions equivalent to -0.5(1.7+1.7) are -0.5(1.7) - 0.5(1.7)

and 2(-0.5(1.7))

The side length of the base of a square pyramid is 30 centimeters. The height of the pyramid is 45 centimeters.

puteri [66]

Answer:

volume = 13500 $cm^{3}$

Step-by-step explanation:

For a given pyramid, its volume can be determined by:

volume of pyramid = $\frac{lwh}{3}$

Where: l is the base length, w is the base width and h id the height of the pyramid.

For the given question, l 30 cm, w = 30 cm and h = 45 cm.

So that,

volume = $\frac{30*30*45}{3}$

= $\frac{40500}{3}$

= 13500

volume = 13500 $cm^{3}$

The volume of the pyramid is 13500 $cm^{3}$ .

Given the figure below, find the values of x and z.<br> X=<br> Z=<br> (11x - 93)<br> H<br> 116<br> X

Marrrta [24]

Answer:

x = 19

z = 64

Step-by-step explanation:

Angles (11x - 93)° and 116° are vertical angles, so their measures are equal.

11x - 93 = 116

11x = 209

x = 19

Angles z° and 116° are a linear pair, so they are supplementary, and their measures have a sum of 180°

z + 116 = 180

z = 64
