in a class test (+ 5) marks are given for every correct answer and (-3) marks are given for every incorrect answer.
a) Anu gets 8 correct answer and 12 incorrect answers what is her score?
b) Sam answered all the questions and scored 28 marks though he got 11 correct answers.
How many incorrect answers had he attempted?
● Please answer my question and I do not need any links
Answer:
a. 4 marks b. 9 questions
Step-by-step explanation:
a) Anu gets 8 correct answer and 12 incorrect answers what is her score?
Since Anu got 8 correct answer and 12 incorrect answers, and + 5 marks is given for every correct answer and (-3) marks are given for every incorrect answer, the total score for correct answers is number of correct answer × marks for correct answer = 8 × (+ 5) = 40.
Also, the total score for incorrect answers is number of incorrect answer × marks for incorrect answer = 12 × (- 3) = -36.
Anu's total score = total score for correct answers + total score for incorrect answers = 40 + (-36) = 40 - 36 = 4 marks.
So, Anu scored 4 marks.
b) Sam answered all the questions and scored 28 marks though he got 11 correct answers. How many incorrect answers had he attempted?
Let x be the number of incorrect answers. Since the marks for incorrect answers is -3, then his total score for incorrect answers is -3x.
Since Sam got 11 correct answers and is given + 5 marks for each correct answer, then his total score for correct answers is 11 × (+5) = +55.
Since he gets a total of 28 marks, we have that total score for incorrect answer + total score for correct answer = 28.
So, -3x + 55 = 28
Solving for x, we have
-3x = 28 - 55
-3x = -27
x = -27/-3
x = 9
Since x = 9, Sam attempted 9 incorrect questions.

In ΔQRS, the measure of ∠S=90°, QS = 12, RQ = 13, and SR = 5. What is the value of the tangent of ∠R to the nearest hundredth?
Answer:
2.40
Step-by-step explanation:
From the triangle QRS
RQ is the hypotenuse 13
QS is the opposite = 12
SR is the adjacent = 5
According to SOH CAH TOA
tan <R = opp/adj
Tan <R = qs/sr
Tan <R = 12/5
Tan <R = 2.40
What is the factored form of 25x2 – 20x + 4?
A. (5x – 2)2
B. (5x + 2)2
O C. (5x + 1)(5x – 4)
D. (5x + 2)(5.x - 2)
Answer:
Step-by-step explanation:
This factors using a perfect square trinomial. You can recognize this by several characteristics. First off, the leading coefficient is a perfect square (25); second, the constant is also a perfect square (4). Third, the second sign is a + which means that both the signs inside the parenthesis are the same and they are both whatever the first sign is, - . Factoring this then, is the (square root of the leading coefficient times x - square root of the constant):
(5x - 2)(5x - 2) which simplifies down to

What is slope? Describe it and provide an real life example.
Answer:
The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Answer: Unlock code = 76
==========================================================
Explanation:
Use a factor tree to find the prime factorization of each value
22 = 2*11
30 = 2*3*5
Both values have '2' in common and this is the largest such value. Therefore, the GCF of 22 and 30 is 2.
So E = 2
----------------------------
Since 3 and 8 have no factors in common (other than 1), this means the LCM is 3*8 = 24
We can say that F = 24.
If the numbers had some larger number in common, then we'd have to do a bit more work to find the LCM.
----------------------------
As the hint suggests, we'll use the distributive property to show that
3*(7+10) = G + 30
3*7 + 3*10 = G + 30
21 + 30 = G + 30
21 = G .... subtract 30 from both sides; they cancel and go away
G = 21
----------------------------
Use the same idea for the other equation as well
5*(3 + H) = 15 + 45
5*3 + 5*H = 15 + 45
15 + 5H = 45
5H = 45 ............ subtract 15 from both sides; they go away
H = 45/5 ......... divide both sides by 5
H = 9
------------------------------
The unlock code is
E+F+G+H = 2+24+21+29 = 76

Step-by-step explanation:
74+47=x(sum of two interior opposite angle is equal to the exterior angle formed)
121=x
What are the x intercepts and y intercept
the x intercepts would be the right and left number (-5.196,0) (5.196) usually most of times the x intercepts would have negative and positive same answers and they usually run vertically while they y intercepts is where the the x and y intercepts meet they usually meets in the y axis so that would be (0,5.4) that is my way of explaining it.

p. s x= 110
y=120
Step-by-step explanation:
Let's take the blank space between y° and 40° as n°. Then let's solve angle AFC, and remember x is given, 110°.
x°+ n°+ 50° = 180°
110°+50°+n°=180°
160°+n° =180°
n = 180° - 160°
n = 20°
Remember that angle y, angle 40° and angle n are on a straight line, which means they add up to 180°. So
y + n°+ 40°=180°
y +20° +40° = 180°
y+ 60° =180°
y = 180° - 60°
y = 120°

Step 1: –10 + 8x < 6x – 4
Step 2: –10 < –2x – 4
Step 3: –6 < –2x
Step 4: ________
What is the final step in solving the inequality –2(5 – 4x) < 6x – 4?
x < –3
x > –3
x < 3
x > 3
Answer:
The process of solving the inequality will be: -2(5 - 4x) < 6x - 4 8x - 10 < 6x - 4 -6 < -2x x > 3 This is in accordance to the rule of solving inequalities which states that whenever we multiply or divide by a negative number while solving an inequality, we must reverse the inequality sign.
