Answer:

x=8.2

Step-by-step explanation:

First, figure out which trig function you are going to use.

In this problem you are dealing with the opposite side to the angle and the hypotenuse, and if you remember SOH CAH TOA, this requires sine.

sin (55) =opposite/hypotenuse

sin (55) =x/10

multiply both sides by 10 to get 10 * sin (55) = x

10 * sin (55) = 8.2

Find the following list of data calculate a demean be the maid and see mode or mothers for the following numbers listed in the p
Sholpan [36]

Answer:

Mean = 4.8875

Median = 4.6

Mode = 4.5 and 7.7

Step-by-step explanation:

Mean is the sum of total of data divided by the sample size

Sum total = 1.5 + 4.7 + 6 + 7.7 + 7.7 + 4.5 + 2.5 + 4.5

Sum total = 39.1

Sample size = 8

Mean = 39.1/8

Mean = 4.8875

To get the median we need to first rearrange

1.5, 2.5, 4.5, 4.5, 4.7, 6, 7.7, 7.7

Median = 4.5 + 4.7/2

Median = 4.6

Hence the median is 4.6

Mode is the value occuring the most. Since 4.5 and 7.7 both occurs twice, hence the mode of the data is 4.5 and 7.7

Given that 1 kilogram weighs approximately 22 pounds, rewrite 10 pounds as an equivalent number of kilograms
yaroslaw [1]

Answer:

0.4545 kgs.

Step-by-step explanation:

Given that 1 kg weighs approximately 22 pounds.

i.e. 1kg= 22 lbs.

We can use this to convert lbs into kg.

22 lbs = 1 kg

Hence 1 lb = 1/22 = 0.04545 kg

Now to find out the equivalent weight for 10lbs,

we have conversion factor as 1 lb= 0.04545 kg

Hence 10 lbs = 10(0.04545) = 0.4545 kgs

Hence 10 pounds written in equivalent kgs would be0.4545 kgs.

                                         <u>Answer and Explanation</u>

<u>__________________________________________________________</u>

<h2>The solution of the equation is 20. </h2><h3>( The value of x. )</h3>

<u>__________________________________________________________</u>

<em>The value of x is 20.</em>

<em>We can figure this out by...</em>

<u>__________________________________________________________</u>

<u></u>\frac{3x}{5}-x=\frac{x}{15}-\frac{28}{3}<em> but what does x equal?</em>

<u></u>\frac{3\cdot20}{5}-20 = -8

\frac{20}{15}-\frac{28}{3} = -8

<em>Since both are equal to -8, that means </em>\frac{3\cdot20}{5}-20 = \frac{20}{15}-\frac{28}{3}.

<em>Which means that...</em>

<em>x = 20</em>
