Yes these kind of questions often confuse us ! Anonymouses should ask the question more nicely!

Just do what the question says.

1% of 1225100

=1/100 * 1225100

You could be correct, rosala...I thought it was an equation....either way, he/she has two different answers to choose from - depending upon what was meant !!!

2 hrs + 50 min = 170 min

170 x 62 = 10540 min / 60 min = about 176.66 hrs. = about 7.3 days

CPhill I think anonymous means x=90 

You have used a trial and error method to solve this.   (Even though you only had one trial)  Your answer is correct.

Try  watching how other questions like this are solved and you will learn the high school method. 

Some questions are just too difficult to use trial and error  

x=90(x/100 + 1/3)    distribute the 90 across the terms in the parentheses

x = (9/10)x + 30       subtract (9/10)x from both sides

(1/10)x = 30             multiply both sides by 10

x = 300

You have the set-up correct.....!!!

(20 - 8)Q - 70000 = (20-10)Q    simplify this

12Q - 70000 = 10Q                

2Q = 70000

So the break-even point is 35000 units.....

If the company can sell more than this, they should produce the product themselves.

Does this make sense??

I assume we have

Pm=(15-5.50)Q-20000=(15-6.50)Q-0=Pb

Simplifying, we have

9.5Q - 20000 = 8.5Q    so

Q = 20000 and this is the break-even point

What i have so far: Pm=(20-8)Q-70000=(20-10)-0=Pa  theirfor Q=  

Not sure if correct though now sure how to work through this equation

y = 9sin[(1/3)(x +1/4)] = 9sin[(4x + 3)/12]

Here's the graph

You are left with 10 lollies

yum dont eat them all at once. . . 

Both 43 and 97 are prime numbers, so this fraction is not capable of being reduced.

3.2x^3.2 = .9x^.9     divide both sides by 3.2

x^3.2 = (.9/3.2) x^.9  divide both sides by x^.9

x^3.2-.9 = (.9/3.2)

x^2.3 =   (.9/3.2)   take the log of both sides

log x^2.3 = log(.9/3.2)      and by a log property, we can write

2.3 log x  = log (.9/3.2)   divide both sides by 2.3

log x   =  [log(.9/3.2)]/2.3   and in exponential form, we can write

10 ^{[log(.9/3.2)]/2.3} = x  = about .576

At 2000 units at a price of $80, the profit is given by

2000(80-45) - 40000 = $30000

At 1500 units at a price of $100, the profit is given by

1500(100-45) - 40000 = $42500

Selling at the higher price generates more profit.

Here you go....

I will take it from there.

$$4(x+2)=5x$$

Now, substitute the $$x$$, but I will start with 8.

$$4(x+2)=5x\Rightarrow4(8+2)=5(8)\Rightarrow4(10)=40\Rightarrow40=40\\\\\mbox{We\;can\;now\;see\;that\;the\;equation\;is\;true,\;so\;}x=40.$$

Is there a value for q?

$$\mbox{q}=?$$

Nice answer Melody! I need more info. in the simplifying part.

$${\sqrt{{\mathtt{20}}}}$$  is called an irrational number.  That means that it cannot be expressed as a fraction or as a decimal.

Ansy answer that your calculator gives you is just an estimate.  All the digits on your calculator will be used up because the digits just keep going on for ever and there is never any pattern.   

You can simplify it to  

 $${\sqrt{{\mathtt{4}}{\mathtt{\,\times\,}}{\mathtt{5}}}} = {\mathtt{4.472\: \!135\: \!954\: \!999\: \!579\: \!4}}$$

$${\sqrt{{\mathtt{4}}}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{5}}}} = {\mathtt{4.472\: \!135\: \!954\: \!999\: \!579\: \!4}}$$

$${\mathtt{2}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{5}}}} = {\mathtt{4.472\: \!135\: \!954\: \!999\: \!579\: \!4}}$$

Are there any questions that I could solve?

$${\mathtt{\,-\,}}{\frac{{\mathtt{18}}{\mathtt{\,\times\,}}{\mathtt{3}}}{{\mathtt{4}}}} = {\mathtt{\,-\,}}{\frac{{\mathtt{27}}}{{\mathtt{2}}}} = -{\mathtt{13.5}}$$

$$-\frac{27}{2}=13\frac{1}{2}$$

Be someone in life! That's to be an ultimate swagger. If your a gangster, you're not an ultimate swagger.

I am on a phone so can't see your pic nicely and not can understand what your questions real meaning but tho I'll do my bit to help u so equations are formed by expressions and they have two expressions on each side of the equal sign and those expressions r of the same value . An example of an equation is 

5 + 10 =10+5 

 Or 

x +10 = 10+5

in the above equation u could see that both the sides have the same value

I don not get this conversation.
