so the difference is 300 - 230 = 70.

now, if we take 230 to be the 100%, what is 70 off of in percentage?

\bf \hspace{34em}|\\\\ \begin{array}{ccll} amount&\%\\ \cline{1-2} 230&100\\ 70&x \end{array}\implies \cfrac{230}{70}=\cfrac{100}{x}\implies \cfrac{23}{7}=\cfrac{100}{x} \\\\\\ 23x=700\implies x=\cfrac{700}{23}\implies x\approx 30.43

Answer:23%

Step-by-step explanation:

300-230=70

70/300=0.23(3 goes on forever)

So 23%

subtract the original with the decreased value, then divide the answer you get with 300. That should equal 0.23 or 23%

Find the mean,median and range of the following list of values and choose the correct result.
Aloiza [94]

Mean: 10.5

Median: 10.5

Range: 5

--------------------------------------------

<u></u>

To find the mean you order the numbers then add then divide.

<u>Add</u>

8+9+10+10+10+11+11+11+12+13=105

<u>Divide</u>

105÷10=10.5

Mean = 10.5

--------------------------------------------

<u></u>

Finding the median essentially involves finding the value in a data sample that has a physical location between the rest of the numbers.

Find the middle number. Put your left finger on 8 and your right finger on 13. Move your left finger to the right to 10 and move your right finger to 11.

the middle number is 10.5 so therefore it is the median.

--------------------------------------------

<u></u>

To find the range you subtract the biggest number to the smallest number.

<u>Subtract</u>

13-8=5

Therefore 5 is the range

3. Given the image below, find the measure of ZYVZ, in degrees.<br> (3x + 5)º<br> N
pashok25 [27]

Answer:

∠ YVZ = 56°

Step-by-step explanation:

∠ WVZ = 90° ( given ), thus

∠ WVY + ∠ YVZ = 90, substitute values

2x + 3x + 5 = 90

5x + 5 = 90 ( subtract 5 from both sides )

5x = 85 ( divide both sides by 5 )

x = 17

Thus

∠ YVZ = 3x + 5 = 3(17) + 5 = 51 + 5 = 56°

Y=–3x + 6y=9 What is the solution to the system of equations? (–21, 9) (9, –21) (–1, 9) (9, –1)
weqwewe [10]

ANSWER


The solution is (-1,9)

EXPLANATION

We want to solve the simultaneous equations


y=-3x+6---(1)


and


y=9--(2).


We substitute equation (2) in to equation (1), to obtain


9=-3x+6


This has now become a linear equation in a single variable x.


We solve for x  by grouping like terms.


9-6=-3x


3=-3x


We divide through by negative 3 to get;


-1=x.


Hence, the solution is (-1,9)
