Olivia scored 82 points on the first mathematics test of the year. On the second mathematics test, she scored 78 points. What is
Kryger [21]

The percent of change in the number of points she scored between the first and second tests  = 4.878 %

<h3>What is percentage decrease?</h3>

If the data is decreasing,

Decrease = Original Number - New Number.

Then: divide the decrease by the original number and multiply the answer by 100.

% Decrease = Decrease ÷ Original Number × 100.

Given that:

The score of first Math test = 82

The score of second Math test = 78

Changes occurs in marks by=78-82

                                               =-4

So, there is decrease in marks.

We have to find the decrease percentage:

Decrease%= \frac{change \;in \;value}{Original\; value} *100

                   = \frac{4}{82} *100

                   = 0.04878 * 100

                  = 4.878 %

There is 4.88% decrease in Olivia's score.

nasty-shy [4]

Answer:

81.2\:\mathrm{ft}

Step-by-step explanation:

We can form a right triangle and use basic trig for a right triangle to solve this problem:

\tan33^{\circ}=\frac{h}{125}, where h is the height of the tree.

Solving, we get:

h=125\cdot \tan 33^{\circ},\\h\approx \fbox{$81.2\:\mathrm{ft}$}.

Enter the degree of the polynomial below.<br> 6x^6+ 9x^3+ 3x^2 - 4x^10 - 9x^5 – 5x^6
mafiozo [28]

The degree of a polynomial is simply the monomial with a coeficient that has the highest degree.

6x^6 = 6 degree

9x^3 = 3 degree

3x^2 = 2 degree

-4x^10 = 10 degree

-9x^5 = 5 degree

-5x^6 = 6 degree

Because -4x^10 has the highest degree, the degree of this polynomial is 10.
