A+b+c= 3932

a=b+1330
a=c+1740 ⇒c=a-1740⇒c=(b+1330)-1740

Obt. 

b+1330 +b+(b+1330)-1740=3932 ⇒3b+2660-1740=3932⇒3b+920=3932⇒3b=3932-920⇒3b=3012⇒b=3012/3⇒\boxed{b=1004}


a=b+1330⇒a=1004+1330⇒\boxed{a=2334}

c=a-1740⇒c=23334-1740⇒\boxed{c=594}

lilavasa [31]

Answer:

I think it's 105.

Step-by-step explanation:

The wording is sort of unclear, but I drew it out and it seems that they are alternate interior angles. Alternate interior angles are congruent! If this is not the right answer, please tell me and I might be able to tell another one.

Well, technically, it has to be either 75 or 105, because all of the special relationships of triangles are either that they are supplementary or they are congruent. So if it's not 105, try 75 :)

gavmur [86]
Hopefully this helps: 16(x^2 + 6x + y^2) = 5(8y + 63)

I'm not sure where to take it from there, but hopefully someone can build off of that. :)

A scientist has discovered a new strain of bacteria. The bacteria culture initially contained 1000 bacteria and the bacteria are
Anna007 [38]

Answer:

Bacteria Culture = B

Hour = H

<u>B=1000*2^H</u>

Step-by-step explanation:

Every hour, the bacteria doubles. This means that the amount is multiplied by 2 every hour. If it was 5 hours in, the bacteria would be at 32000. You can use the equation B=1000*2^5 to get that answer.
