Hey there! I'm happy to help!

Let's represent Tom's money as T, Ulrika's as U, and Harriet's as H. Let's put the information we have in a system of equations and solve the problem.

H=3U                       (Harriet has 3x as much as Ulrika)

H=T+304                      (Harriet has 304 more than Tom)

T=U                          (Tom has same amount as Ulrika.)

We see that 3U and T+304 are equal because they both equal H.

3U=T+304

Since T and U are interchangeable because they are equal, we can replace the U with T to solve for T, which is also the answer for U.

3T=T+304

We subtract T from both sides.

2T=304

We divide both sides by 2.

T=152

This also means that U=152.

So, Ulrika has $152.

Have a wonderful day!

Describe one error that was made in the preparation of the
pashok25 [27]

Answer:

  the axis labels are inconsistent with the graph title

Step-by-step explanation:

The independent variable is described as "% protein digested", and the dependent variable is described as "time." The graphed values suggest that these are reasonable descriptors for the data being plotted.

The title, however, says the data points are "percentage digestion per hour". This is in disagreement with the axis labels, and is inconsistent with the shape of the curve. (If the title is to be believed, the digestion rate is such that more than 100% of <whatever> has been digested after 10 hours.)

<em>Additional comment</em>

Another error is the vertical axis is graduated as though it were linear, but it is decidedly non-linear. Equivalent distances on the graph are shown for differences of 10%, 5%, 10% and 25%. That is the scale varies by a factor of 5 from one part of the graph to another.

Which relation is a function
lesantik [10]

Answer:

option 2nd

Step-by-step explanation:

You've selected wrong one

it's first row, last one

to find the graph is a function or not, it should pass vertical line test.

Draw a vertical line through each graph. It should not cut your graph more than once.

2nd graph from first row is passing vertical line test. so it is a function b
