14)

check the picture below... so.. is just a semi-circle and a rectangle, nothing fancy, get their area, sum them up.

15)

so... the voter turnout, is referring to, what's the percentage that voted, which year has the highest percentage... well, we simply check the percentage of the value provided from the total eligible voters, keeping in mind that, all eligible voters are the 100%

so.. for 1944

\bf \begin{array}{ccllll}
amount&\%\\
------&----\\
86,607,000&100\\
47,976,670&x\\
\end{array}\implies \cfrac{86,607,000}{47,976,670}=\cfrac{100}{x}
\\\\\\
x=\cfrac{100\cdot 47,976,670}{86,607,000}\implies x\approx 55.39583405498

for 1984

\bf \begin{array}{ccllll}
amount&\%\\
-----&-----\\
167,727,000&100\\
92,659,000&x
\end{array}\implies \cfrac{167,727,000}{92,659,000}=\cfrac{100}{x}
\\\\\\
x=\cfrac{100\cdot 92,659,000}{167,727,000}\implies x\approx 55.2439380660239

If you were to use the substitution method to solve the following system, choose the new
mestny [16]

Answer:

23x = -115

Step-by-step explanation:

In the substitution method, you must solve for 1 variable in 1 equation to replace it in the other equation. For the system:

2x - 7y = 4

3x + y = -17

Solving for y in the second equation:

y = -17 - 3x

Replacing y in the first equation:

2x - 7(-17 - 3x) = 4

2x + 119 + 21x = 4

23x = -115

This is the new equation after use the substitution method.

Write 12 ten thousands, 8 thousands,14 hundreds, 7 ones in standard form
Cloud [144]
<span><u><em>The correct answer is: </em></u>
129,407.

<u><em>Explanation</em></u><span><u><em>: </em></u>
12 ten-thousands = 12*10000=120,000.
8 thousands = 8*1000=8000;
<u>this gives us</u> 120,000+8,000=128,000.

14 hundreds = 14*100=1400;
<u>this gives us</u> 128,000+1,400=129,400.

7 ones = 7*1=7;
<u>this gives us</u> 129,400+7=129,407.</span></span>

Make x the subject! urgent help
Serhud [2]

Answer:

x =  \frac{n}{b -  {t}^{2} }

Step-by-step explanation:

I supposed that is a "n".

Steps as below:

{t}^{2}  = b -  \frac{n}{x}  \\ b -  \frac{n}{x}  =  {t}^{2}  \\  -  \frac{n}{x}  =  {t}^{2}  - b \\  \frac{n}{x}  =  - ( {t}^{2}  - b) \\  \frac{n}{x}  = b -  {t}^{2}  \\ n = x(b -  {t}^{2} ) \\ x(b -  {t}^{2} ) = n \\ x =  \frac{n}{b -  {t}^{2} }

Solve 9,159 divided by 7
aniked [119]

Answer:

(9159 / 7 = 1308.429)

Step-by-step explanation:

Simply multiply the last digit by 2 and then subtract the product from the remaining digits.

If that difference is divisible by 7, then 9159 is divisible by 7.

The last digit in 9159 is 9 and the remaining digits are 915. Thus, the math to determine if 9159 is divisible by 7 using our alternate method is:

915 - (9 x 2) = 897

Since 897 is not divisible by 7, 9159 is also not divisible by 7.

Therefore, the answer to "Is 9159 Divisible By 7?" is no.

(9159 / 7 = 1308.429)
