8 0

Answer:

y=4

Step-by-step explanation:

<h3>The triangle is divided further into 2 right triangles. So ignore the left one.</h3><h3>We know the angle of elevation is 30° and the hypotenuse is 8.</h3><h3>Looking at SOH CAH TOA we use the sine ratio in trigonometry because we have to find the side opposite to the angle given and we know the hypotenuse. </h3><h3>It is: sin 30 = y/8</h3><h3>y= 8 sin 30</h3><h3>y=4</h3>

A medical plan requires a patient to pay a $25.00 copay plus 20% of all charges incurred for a medical procedure. If the average
miss Akunina [59]
Let the original bill be x, then the final bill after the charges been added are 1.2x+25, where 1.2 is the increase in the bill by 0.2 (100%+20% = 120% = 1.2)

The range of the original bill is 
200 < 1.2x+25 < 800, subtract each term by 25
175 < 1.2x < 775, divide each term by 1.2
145.83 < x < 645.83

Hence, the range of the original bill is between $145.83 and $645.83

percentage error = 7.92

HEnce  the percent error in the weight of the package is 7.92%

Perform the indicated operation.<br><br> 4/11 · 10/8<br><br> 4/11<br> 5/11<br> 6/11
Dimas [21]
4/11 * 10/8

Multiplying fractions
1) multiply the numerators: 4 * 10 = 40
2) multiply the denominators: 11 * 8 = 88
3) simplify the fraction
40/88 ⇒ 10/22 ⇒ 5/11

40 ÷ 4 = 10
88 ÷ 4 = 22

10 ÷ 2 = 5
22 ÷ 2 = 11

4/11 * 10/8 = 5/11

Alexandra [31]

Answer: -b - 9

Step-by-step explanation:

First, since the a cancel eachother out we are left with (4-b) + (-6-7)

Second, you want to add the -6 and -7 to get -13, so (4-b) - 13

Finally, add the 4 to the negative 13 to get (-b - 9)

Hope this helps.
