In the DBE 122 class, there are 350 possible points. These points come from 5 homework sets that are worth 10 points each and 3

Sliva [168]

Answer:

i) it is not possible for the student to receive an A in the class

ii) 119 points

iii) 84points

Step-by-step explanation:

Total exam scores = 350points

homework scores of 7, 8, 7, 5, and 8

Let the third exam score =y

Exam scores = 81, 80, x

i) To know if the student would get an A in class, we would find the third exam score

(Scores received by a student)/ (total scores) = least of the grade percentage to get an A

(7 + 8 + 7 +5 + 8 + 81 + 80 + x)/350 = 0.9

(196+x)/350 = 0.9

196+x = 350 × 0.9

196+x = 315

x = 315-196

x = 119

119 > 100

Since the maximum grade for each of the exam score is 100points, it is not possible for the student to receive an A in the class.

ii) Since the least of the grade percentage that would guarantee an A is 0.9, the minimum score on the third exam that will give an A = 119points

iii) (Scores received by a student)/ (total scores) = least of the grade percentage to get a B

(7 + 8 + 7 +5 + 8 + 81 + 80 + x)/350 = 0.8

(196+x)/350 = 0.8

196+x = 350 × 0.8 = 280

x = 280-196

x = 84

The minimum score on the third exam that will give a B = 84points

PLEASE HELP A QUESTION OF LIFE OR DEATH!!!!!!!

Answer: The length of the third straw is 29 centimeters.

Step-by-step explanation: Given that Anja is creating a triangle using three straws and the lengths of two shorter straws are 20 cm and 21 cm.

We are to find the length of the third straw in centimeters so that Anja will create a right triangle.

The two shorter straws will make the legs of the right-angled triangle because they are shorter.

Since the third straw will be the largest, so it will make the HYPOTENUSE of the triangle.

In a right-angled triangle, we have

Hypotenuse² = length of one leg² + length of the other leg².

Therefore, we get

$Hypotenuse^2=20^2+21^2=400+441=841\\\\\Rightarrow Hypotenuse=29.$

Thus, the length of the third straw is 29 centimeters.
