Answer:
a 25 questions, 4 points b 19 questions
Step-by-step explanation:
a 96:100 = 24 : x
x = (100 x 24)/96 = 25 questions
100 : 25 = 4 points
b 76:100 = x : 25
x = (76 x 25)/100 = 19 questions
Answer:
Question 1:
There are 25 questions on the test.
Each question is worth 4 marks each.
Question 2:
Your friend answered 19 questions correctly
Step-by-step explanation:
Question 1:
question answered = 24
percent earned = 96%
total number of points = 100%
[tex]\frac{questions answered }{percentage earned}[/tex] x 100
[tex]\frac{24}{96}[/tex] x 100 ⇒ 0.25 x 100 ⇒ 25
there are 25 questions on the test
[tex]\frac{100}{25} = 4[/tex]
each question is 4 marks each
Question 2:
percent earned by your friend = 76%
(percent earned by your friend x total number of question) ÷ 100
76 x 25 ÷ 100
1900 ÷ 100
= 19

An equilateral triangle with side length 9 cm is shown in the diagram, work out the area of the triangle.
Give your answer rounded to 1 DP.
The answer is 35.1 cm².
Hope this helps; have a great day!
Question:-
Find the area of an equilateral triangle with side length = 9cm correct upto one decimal place.
_______________________________________________
Solution:-
In an equilateral triangle all sides are equal.
Let s = side length = 9 cm
Then, area of equilateral triangle is given as:
A = (√3/4)s²
Putting the value of s here,
A = (√3/4) * (9 cm)²
=> A = (√3/4) * 81 cm²
=> A = √3 * 20.25 cm²
We know that, √3 = 1.732
=> A = 1.732 * 20.25 cm²
=> A = 35.073 cm²
Rounding to one decimal place,
=> A = 35.1 cm²

Mr. Tajpuriya paid Rs 6,780 for a television with a discount of 20% including 13% VAT.what is the marked price of the television?
Answer:
I'm not really sure about the marked price but you could choose between these
Step-by-step explanation:
6780×13=881.4
6780-881.4=R5898.6 (the price with out the VAT)
6780×20%=1356
6780-1356=R5424 (the price with out the discount)
6780-1356-881.4=R4542.6 (the price without the discount and VAT)

Two straight lines are shown.
Answer:
(3,20)
Step-by-step explanation:
so O must be 0,0 and A is a midpoint of OB
This means B must be (14,12)
B is the midpoint of TS.
This means that the distance of SB is equal to the distance of BT.
This must mean that the coordinate of T must be (3,20)
O: (0,0) x coordinate increases by 7. y coordinate increases by 6.
A: (7,6)
B: (14,12)
S: (25,4) x coordinate decrease by 11. y coordinate increases by 8.
B: (14,12)
T: (3,20)
The coordinates of T are (3, 20).
What is Straight Line?A straight line is an endless one-dimensional figure that has no width.
From the figure, A is the midpoint of OB and B is the midpoint of TS
The coordinates of O are (0, 0) and Coordinates of A are (7,6)
We can find coordinate of B.
(7, 6)=(0+x/2, 0+y/2)
(7,6)=(x/2, y/2)
x/2=7 and y/2=6
x=14 y=12
So the coordinates of B are (14, 12)
Now we can find the coordinates of T.
(14, 12)=(X+25/2, Y+4/2)
X+25=28
x=3
Y+4=24
Y=20
So the coordinates of T are (3, 20)
Hence, the coordinates of T are (3, 20).

Find the Value of X???
Answer:
x = 5
Step-by-step explanation:
Given two intersecting chords
Then the product of the parts of one chord is equal to the product of the parts of the other chord, that is
2x × 12 = 15(x + 3) , that is
24x = 15x + 45 ( subtract 15x from both sides )
9x = 45 ( divide both sides by 9 )
x = 5
