Hello,

Your triangle XYZ is isosceles and right:

XY²=2*(9*√2)²=4*81=(2*9)²=18²
So |XY|=18

scZoUnD [109]

Answer:

Step-by-step explanation:

let x represent lemonade and y represent orange juice

the total earning is $240. 2x+3y=240 allows you to find the number of each cup you need to sell to get $240.

the total number of cups sold is 100. x+y=100 gives you the other equation necessary to find the number of cups of each sold if you told a total of 100

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

What is pi divided by 2/3?

klasskru [66]

Given:
pi is equal to 3.14

3.14 ÷ 2/3

Rules in dividing fractions.
3.14 is the 1st fraction. It has a denominator of 1. 3.14/1
2/3 is the 2nd fraction

1) get the reciprocal of the 2nd fraction.
2/3 ⇒ 3/2

2) multiply the 1st fraction to the reciprocal of the 2nd fraction
3.14 * 3/2 = (3.14*3) / 2 = 9.42 / 2 = 4.71

Pi divided by 2/3 is 4.71
