A^2+b^2=c^2 so c^2=12^2+16^2 which then simplifies to c^2=144+256 then simplify that to c^2=400. After that take the square root of c^2 and the square root of 400. So your answer is c=20

Which set of equations would have infinitely many solutions? JUSTIFY your answer in #4.
Ierofanga [76]

Answer:

2nd option: 2y=6x+8 and y=3x+4

Step-by-step explanation:

If you divide the first by 2, you get the second equation.

This means that both equations plot an identical line (they lie on top of each other /also known as "coincide"). This means, that there are infinitely many solutions.

In 2D (x-y plane for example), straight lines can have no solutions if they have the same gradient/slope/ they are parallel and different y-intercepts, because they will never cross.

Here, they have same gradient and y-intercept so all points on the line are valid solutions to the equation

Another project on Kickstarter for an iPad stylus raised 1,253% of their goal, raising a total of $313,490 from 7,511 supporters
SpyIntel [72]

Answer:

The original goal is $25019.154 .

Step by step Explanation:

Let us assume that the origianl goal be x .

As given

Another project on Kickstarter for an iPad stylus raised 1,253% of their goal, raising a total of $313,490 .

1253% is written in the decimal form .

= \frac{1253}{100}

= 12.53

Than the equation becomes

12.53 × x = 313490

12.53x = 313490

x = \frac{313490}{12.53}

x = $ 25019.154

Therefore the original goal is $25019.154 .
