100-50=50.

There are 50 apples left over

251.86 is the answer

The square root is 10

I have assigned my best agents to this investigation. A full report will follow soon.

In the mean time, I know there is a lack of moderation, because I am on my third double.

Draw each triangle, label all three angles, and put in the measurements that you know.

Circle the angle that you want to find. In relation to this angle, label the three sides as "opp" (for "opposite"), "adj" (for "adjacent", and "hyp" (for "hypotenuse").

If you know the two sides opp and hyp, use sin:  sin(angle) = opp/hyp.

If you know the two sides adj and hyp, use cos:  cos(angle) = cos/hyp.

If you know the two sides opp and adj, use tan:  tan(angle) = opp/hyp.

You are finding the area of a triangle, using the formula:  Area  =  0.5·a·c·sin(B)

You know the values of all the variables that you need:    Area  =  0.5·5·6·sin(11.8)

Enter this into your calculator, and you will have the answer.

(2·22) / 2²

I would do what's inside first:  2·22 = 44

44 / 2²

I would handle the exponent next:  2² = 4

44 / 4  =  11

$$\left({\mathtt{9}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{50}}}{{\mathtt{60}}}}\right){\mathtt{\,\times\,}}{\mathtt{7}} = {\frac{{\mathtt{413}}}{{\mathtt{6}}}} = {\mathtt{68.833\: \!333\: \!333\: \!333\: \!333\: \!3}}$$

i think that you mean 'trial and improvement"

Given that X lies between 5 and 6 use trail and improvement to solve X^3- 6X=126.

0=x^3-6x-126

try x=5.5

$${{\mathtt{5.5}}}^{{\mathtt{3}}}{\mathtt{\,-\,}}{\mathtt{6}}{\mathtt{\,\times\,}}{\mathtt{5.5}}{\mathtt{\,-\,}}{\mathtt{126}} = {\frac{{\mathtt{59}}}{{\mathtt{8}}}} = {\mathtt{7.375}}$$

try 5

$${{\mathtt{5}}}^{{\mathtt{3}}}{\mathtt{\,-\,}}{\mathtt{6}}{\mathtt{\,\times\,}}{\mathtt{5}}{\mathtt{\,-\,}}{\mathtt{126}} = -{\mathtt{31}}$$

So it is between 5 and 5.5

Try 5.2

$${{\mathtt{5.2}}}^{{\mathtt{3}}}{\mathtt{\,-\,}}{\mathtt{6}}{\mathtt{\,\times\,}}{\mathtt{5.2}}{\mathtt{\,-\,}}{\mathtt{126}} = {\mathtt{\,-\,}}{\frac{{\mathtt{2\,074}}}{{\mathtt{125}}}} = -{\mathtt{16.592}}$$

So it is between 5.2 and 5.5

try 5.4

$${{\mathtt{5.4}}}^{{\mathtt{3}}}{\mathtt{\,-\,}}{\mathtt{6}}{\mathtt{\,\times\,}}{\mathtt{5.4}}{\mathtt{\,-\,}}{\mathtt{126}} = {\mathtt{\,-\,}}{\frac{{\mathtt{117}}}{{\mathtt{125}}}} = -{\mathtt{0.936}}$$

So it is between 5.4 and 5.5

Try 5.45

$${{\mathtt{5.45}}}^{{\mathtt{3}}}{\mathtt{\,-\,}}{\mathtt{6}}{\mathtt{\,\times\,}}{\mathtt{5.45}}{\mathtt{\,-\,}}{\mathtt{126}} = {\mathtt{3.178\: \!625}}$$

So it is between 5.4 and 5.45

So to 1 decimal place it is 5.4

Thanks Chris  :))

$${\frac{{\mathtt{37}}}{{\mathtt{100}}}}{\mathtt{\,\times\,}}{\mathtt{3\,851\,799}} = {\mathtt{1\,425\,165.63}}$$

Example

$$7\frac{2}{3}\;=\;\frac{7*3+2}{3}\;=\;\frac{21+2}{3}\;=\;\frac{23}{3}$$

Thank you Gino for providing this web address.

I hope to put it to good use in the future.  :)

To answer this question you go wher Gino sent you

$${\frac{{\mathtt{3\,851\,799}}}{{\mathtt{1.37}}}} = {\mathtt{2\,811\,532.116\: \!788\: \!321\: \!167\: \!883\: \!2}}$$

Very nice, Melody........no Calculus required !!!!

Yes - but yours is more impressive.  :)

$$y=a^2+6a-7$$

This is a concave up parabola  (I can explain why if you ask)

$$y=(a+7)(a-1)$$

The roots are a=-7 and a=1

The axis of symmetry is  a=(-7+1)/2 = -3

The minimum value

$$\\y=(-3)^2+6*(-3)-7\\
y=9-18-7\\
y=-16$$

The minimum value is -16

ALTERNATIVELY

It would have been easier to solve this using calculus.   

$$\\\frac{3k}{5}-\frac{1k}{10}=\frac{1k}{2}+1\\\\
10\left(\frac{3k}{5}-\frac{1k}{10}\right)=10\left(\frac{1k}{2}+1\right)\\\\
\frac{30k}{5}-\frac{10k}{10}=\frac{10k}{2}+10\\\\
6k-k=5k+10\\\\
5k=5k+10\\\\
0=10\\\\

what is the % of 4000000.897 in 4000000.897?

4000000.897/4000000.897*100  

then write the percent sign at the end.

Use the site calc on the home page. :)

a*10=8090045757667635534544660

a=809004575766763553454466

I just took the zero off the end.  :)
