Answer:

lets say that the length is L and the width is W. With the given info, we can say that L=5W.

We know that the perimeter is all four sides added, so..

5W*4=20W

20W=96

W=4.8

L= 5*4.8=24

Area is equal to 24*4.8, which is 115.2

Voila! Your answer is 115.2 sq. ft!

To compute a student's Grade Point Average (GPA) for a term, the student's grades for each course are weighted by the number of

Liula [17]

Okay, here we have this:

Considering the provided information and grades, we are going to calculate the requested GPA, so we obtain the following:

Then we will substitute in the following formula:

$GPA=\frac{Grades\ast Credits}{Total\text{ credits}}$

Then:

$\begin{gathered} GPA=\frac{3.8\cdot5+1.9\cdot2+3.0\cdot5+2.8\cdot4}{16} \\ GPA=\frac{19+3.8+15+11.2}{16} \\ GPA=\frac{49}{16} \\ GPA=3.06 \end{gathered}$

Finally we obtain that the student's GPA for that term is approximately 3.06.

RoseWind [281]

Answer:

58.43%

Step-by-step explanation:

In this case we have that the probability that they are different is the opposite of the probability that they are the same, therefore, in each case it would be:

P (plain, plain) = (12/20) (11/19)

P (p, p) = 132/380

P (chocolate, chocolate) = (5/20) (4/19) = 20/380

P (ch, ch) = 20/380

P (currant, currant)= (3/20) (2/19) = 6/380

P (c, c) = 6/380

The probability that they are equal is the sum of each:

P (equal) = 132/380 + 20/380 + 6/380

P (equal) = 0.4157

Therefore, the probability that they are different is:

P (different) = 1 - 0.4157

P (different) = 0.5843 = 58.43%

It means that the probability is 58.43%

5 [a] 8cm 11cm 6cm What is the surface area

Paha777 [63]

Answer:

424 cm²

Step-by-step explanation:

8 x 11 = 88 = 1 side

88 x 2 = 196 = 2 sides

11 x 6 =66 = 3 sides

66 x 2 = 132 = 4 sides

8 x 6 = 48 = 5 sides

48 x 2 = 96 = 6 sides

196 + 132+ 96 = 424
