Answer:

Z = 1

Step-by-step explanation:

Simplify the equation using PEMDAS.

4 x 2 - z = 7

8 - x = 7

- x = 7 - 8

-x = - 1

x = 1

Answer:

The answer is 600.

Step-by-step explanation:

This is because 5 percent of 800 is 40. 800+40 = 840. 15 percent of 800 is 160. 840 - 160 is 680. 10 percent of 800 is 80. 680 - 80 is 600.

I don't believe your expression is correct as is; it should be <span>100(1 + 0.4)^h.

You have not shared the possible answer choices; please do so.

Lyra's speed of travel is 6.71 feet per seconds and Lyra's direction of travel is 27 degrees north of east

<h3>How to determine the speed of travel?</h3>

The diagram that represents the scenario is added as an attachment.

Let x represents Lyra's speed of travel.

The value of x is calculated using the following Pythagoras theorem.

$x = \sqrt{3^2 + 6^2}$

Evaluate the exponents

$x = \sqrt{9 + 36}$

Evaluate the sum

$x = \sqrt{45}$

Evaluate the exponent

x = 6.71

Hence, Lyra's speed of travel is 6.71 feet per seconds

<h3>How to determine the direction of travel?</h3>

The direction (∅) is calculated using the following tangent ratio.

$\tan(\theta) = \frac 36$

Evaluate the quotient

$\tan(\theta) = 0.5$

Take the arc tan of both sides

$\theta = \tan^{_1}(0.5)$

Evaluate

$\theta = 27$

Hence, Lyra's direction of travel is 27 degrees north of east
