Which expression is represented by the model below?

A student earned grades of B, B, A, C, and D. Those courses had these corresponding numbers of credit hours: 4, 5, 1, 5, 4.

antiseptic1488 [7]

Answer:

Step-by-step explanation:

Let the five courses with their corresponding credit hours be represented as shown;

FST 201 = 4

FST 203 = 5

FST 112 = 1

FST 219 = 5

FST 223 = 4

If a student earned grades of B, B, A, C, and D respectively in those courses with the following grading system A =4, B =3, C =2, D =1, and F =0, before we can get the student GPA, we need to know the total credit point for the five courses.

Credit point for each course = Number of credit hour * point for each grade

FST 201 = 4 * 4 = 16points (A)

FST 203 = 5 * 4 = 20points (A)

FST 112 = 1 * 4 = 4points (A)

FST 219 = 5 * 4 = 20points (A)

FST 223 = 4 * 4 = 16points (A)

Total credit point = 16+20+4+20+16 = 76points

Total credit point gotten by the student is calculated as thus;

FST 201 = 4 * 3 = 12points (B)

FST 203 = 5 * 3 = 15points (B)

FST 112 = 1 * 4 = 4points (A)

FST 219 = 5 * 2 = 10points (C)

FST 223 = 4 * 1 = 4points (D)

Total credit point gotten by the student = 45points.

student's Grade Point Average (GPA) = Total credit point/Total credit point gotten by the student = 76/45 = 1.69 (to 2dp)

The regular octagon has a perimeter of 122.4 cm. Which statements about the octagon are true? Check all that apply.

Papessa [141]

Answer:

The length of segment XY can be found by solving for a in

$20^2-7.65^2=a^2$

The measure of the central angle $\angle ZXW$ is $45\degree$ .

Step-by-step explanation:

If the regular octagon has a perimeter of 122.4cm, then each side is $\frac{122.4}{8}=15.3cm$

The measure of each central angle is $\frac{360\degree}{8}=45\degree$

The angle between the apothem and the radius is $\frac{45}{2}=22.5\degree$

The segment XY=a is the height of the right isosceles triangle.

We can use the Pythagoras Theorem with right triangle XYZ to get:

$a^2+7.65^2=20^2$

$a^2=20^2-7.65^2$

Therefore, the correct options are:

The length of segment XY can be found by solving for a in

$20^2-7.65^2=a^2$

The measure of the central angle $\angle ZXW$ is $45\degree$ .

podryga [215]

Answer:

Step-by-step explanation:

8x² + 2(x²-1) = 8x² + 2*x² - 2*1

= 8x² + 2x² -2

= 10x² -2

Steven bought a new computer at the end of a sale. The price of the computer was $52 on the day he bought it. The next day it ha

den301095 [7]

Answer:

$72.80

Step-by-step explanation:

You would multiply 52 with .40 to get 20.8. This is how much the price increased by. Then you would add the 20.8 to your original price of 52 to get 72.80.

(Also you use .40 initially because percent means out of 100. So 40% is the same as .4)

A certain drug is made from only two ingredients, there are five milliliters of part a and four milliliters of part b. If a chem

patriot [66]

You will have to divide 353 millimeters by 4:

353 ÷ 4 = 88.25

now we have to multiply 88.25 by 9 (5+4), the total millimeters of only one portion of this drug

88.25 x 9 = 794.25

So he will make 794.25 millimeters of drug (that is if he has the part a too)

(If you should round 88.25 to 88, the answer would be 88 x 9 = 792)
