Dot got a 75% on her test. She missed 12 questions. how many questions were on the test

1 answer:

7 0

Well, if it was out of 50, it would be 76%.

So the answer might be 50 questions total, but maybe there was 49 questions total.

I would probably go with 50 questions total.

Step-by-step explanation:

<h3>In Solving This You Need to Change It Into Improper Fractions First;</h3>

1 2/5×3 1/2

•You then multiply the 5 by the 1 and then add it to the 2 which is then going to be;

7/5× 3 1/2

•Then you multiply the 2 by the 3 and then add it to the 1;

7/5×7/2

•Then you proceed to multiply the first numerator by the second numerator and then also multiply the first denominator by the second denominator which will be;

14/10

After this you go on to simplify which is going to be;

7/5(NB: It was divided by two)

So mixed number in it's simplest form is going to be;

1 2/5

In Decimal form would have been; 1.4

Since the question is asking for mixed number in it's simplest form it's going to be;

1 2/5

Find The Slope && Y-Intercept Of The Graph ... Y = 6x + 11

Licemer1 [7]

The slope is the term that follows the x, so...

$\boxed{\boxed{slope=6}}$

now, the interception of Y happens when the X is equal 0, then...

$y=6x+11$

$y=6*0+11$

$\boxed{\boxed{y=11}}$

Permutations!!

Advocard [28]

Since the problem specifically stated that the people gather around the table, therefore we assume a circular table hence a circular formation of gathering. Since the arrangement is important therefore we use the permutation.

nPr = n! / (n – r)!

However before we proceed with our calculation we MUST first affix a reference point since the formation is circle. Imagine that the reference point is the 1st point made when you draw a circle, so it is the both the 0 degrees and the 360 degrees.

Let us say that one of the actors is the reference point. So there are now only 8 actors which places can be interchanged. Since all actors have to sit together, hence the arrangements are:

8P8 = 8! / (8 – 8)! = 40,320

Now since there are 13 total people, therefore the arrangements of the other 4 people are:

4P4 = 4! / (4 – 4)! = 24

We multiply all to get the total number of arrangements:

Total arrangements = 40320 * 24 * 1 (1 is the reference point)

Total arrangements = 967,680
