Class A has 12 pupils and class B has 29 pupils.
Both classes sit the same maths test.
The mean score for class A is 52.
The mean score for both classes is 24.
What is the mean score (rounded to 2 DP) in the maths test for class B?
Answer:
The mean score in the maths test for class B was 12.41 points.
Step-by-step explanation:
Given that Class A has 12 pupils and class B has 29 pupils, and both classes sit the same maths test, and the mean score for class A is 52 while the mean score for both classes is 24, to determine what is the mean score in the maths test for class B the following calculation must be performed:
52 x 12 + X x 29 = 24 x (12 + 29)
624 + 29X = 24 x 41
624 + 29X = 984
29X = 984 - 624
X = 360/29
X = 12.41
Therefore, the mean score in the maths test for class B was 12.41 points.
Help Pls. Find the radius of Circle Q.
The radius of the given circle is 13 unit.
What is a chord of a circle?
The chord of a circle can be defined as the line segment joining any two points on the circumference of the circle.
What is radius of a circle?A radius is a measure of distance from the center of any circular object to its outermost edge or boundary.
What is Pythagoras theorem?Pythagoras theorem states that "the square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides".
According to the given question
We have a circle with center Q and two chords AD and BC.
And, AD = 4x + 4 and BC = 6x -6
Since, both the chords are at the same distance from the center of the circle, so their lengths will same.
⇒ AD = BC
⇒ 4x + 4 = 6x -6
⇒ 4 + 6 = 6x -4x
⇒ 10 = 2x
⇒ x = 5
Therefore,
AD = 4x + 4 = 4(5) + 4 = 20 +4 =24
and, BC = 6x - 6 = 6(5) - 6 = 30 -6 = 24
Also, AP = AD/2 = 24/2 = 12
Now, in right angle triangle QPA we have
[tex]AQ^{2} =QP^{2} +AP^{2}[/tex] ( By Pythagoras theorem)
⇒ [tex]AQ^{2} = 5^{2} +12^{2}[/tex]
⇒[tex]AQ^{2} = 25 + 144[/tex]
⇒[tex]AQ^{2} = 169[/tex]
⇒[tex]AQ =\sqrt{169}[/tex]
⇒ AQ = 13
Hence, the radius of the given circle is 13 unit.

A 525ft cable runs from the top of an antena to the ground. The angle of elevation made by the ground to the top of an antena 25°
How tall is the antena ??
Answer:
221.87 feet
Step-by-step explanation:
Given that,
A 525 ft cable runs from the top of an antenna to the ground.
The angle of elevation made by the ground to the top of an antena 25°
We need to find the height of the antenna.
Using trigonometry,
Hypotenuse, H = 525 ft
θ = 25°
So,
[tex]\sin\theta=\dfrac{P}{H}\\\\P=H\sin\theta\\\\P=525\times \sin(25)\\\\P=221.87\ ft[/tex]
So, the height of the antenna is equal to 221.87 feet.

The volume of a pyramid that fits exactly inside a cube is 10 cubic feet. What is the volume of the cube? (5 points)
30 cubic feet
100 cubic feet
300 cubic feet
1000 cubic feet
Answer:
30 cubic feet
Step-by-step explanation:
volume of a pyramid is (l*w*h)=3
assuming it is a pyrmaid where l=w=h, volume = x^3/3 = 10
x^3=30
x=30^(1/3)
volume of a cube is l*w*h, with our assumption, that translates to x*x*x
Volume = 30^(1/3)*3 = 30 cubic feet
The volume of the cube, in relation to the given pyramid is: 30 cubic feet.
What is a Cube?Volume of a pyramid = 1/3(l × w × h)Volume of a cube = l × w × hRelating both volumes, we would have:
Volume of cube = 3(volume of pyramid)
Volume of pyramid is given as 10 cubic feet, therefore:
Volume of the cube = 3(10)
Volume of the cube = 30 cubic feet.

The area of the room is 147.5 square feet so Michelle's reasoning was incorrect.
Step-by-step explanation:
Step 1:
To calculate the area of the given room, we divide the unknown shape into known shapes.
The room's shape is made of 2 rectangles.
The area of a rectangle is the product of its length and its width.
One rectangle has a length of 10 feet and a width of 12 1/2 feet.
The other rectangle has a length of 15 - 10 = 5 feet and a width of 4 1/2 feet.
Step 2:
The area of the first rectangle = (10)(12 1/2) = (10)(12.5) = 125 square feet.
The area of the second rectangle (10)(4 1/2) = (5)(4.5) = 22.5 square feet.
The total area of the room = 125 + 22.5 = 147.5 square feet.
Answer:
147.5ft²
Step-by-step explanation:
10 × 12¹/₂ = 125
5 × 4¹/₂ = 22¹/₂
Total area = 125 + 22¹/₂
Total area = 147¹/₂ = 147.5

Explanation:
8 jars need 1.8 kg of caster sugar.
Cut each value in half to see that 4 jars need 0.9 kg of caster sugar.
Convert 0.9 kg to grams to get 900 grams (multiply by 1000 to go from kg to grams).
Jayne needs 900 grams of caster sugar. She has 860 grams already, which means she needs an additional 900-860 = 40 grams
The speed of an electron in an orbit around hydrogen atom is 2.2*10^6 ms^-1.It takes 1.5*10^-16 s for the electron to complete one orbit. Calculate the radius of the orbit. please help me ASAP!!
Answer:
5.3×10⁻¹¹ m
Step-by-step explanation:
Applying,
v = 2πr/t................ Equation 1
Where v = speed of the electron in the orbit, r = radius of the orbit, t = time, π = pie
make r the subject of the equation
r = vt/2π................ Equation 2
From the question,
Given: v = 2.2×10⁶ m/s, t = 1.5×10⁻¹⁶ s
Constant: π = 3.14
Susbtitute these values into equation 2
r = (2.2×10⁶×1.5×10⁻¹⁶)/(3.14×2)
r = (3.3×10⁻¹⁰)/6.28
r = 5.3×10⁻¹¹ m
Hence the radius of the orbit is 5.3×10⁻¹¹ m
Answer:
The radius of the orbit is: [tex]R=0.525 \AA[/tex]
Step-by-step explanation:
The period of a circular motion is the time to complete one orbit, then:
[tex]T=1.5*10^{-16}s[/tex]
Now, let's recall the tangential speed can be written as:
[tex]v=\frac{2\pi R}{T}[/tex]
R is the radius of the motion.
Let's solve the above equation for R.
[tex]R=\frac{vT}{2 \pi}[/tex]
[tex]R=\frac{2.2*10^{6}1.5*10^{-16}}{2 \pi}[/tex]
[tex]R=\frac{2.2*10^{6}1.5*10^{-16}}{2 \pi}[/tex]
[tex]R=5.25*10^{-11} \: m[/tex]
Therefore, the radius of the orbit is: [tex]R=0.525 \AA[/tex]

Answer:
Step-by-step explanation:
8x-9+2+9x=180 degree(being co interior angles)
17x-7=180
17x=180+7
x=187/17
x=11 degree
Answer:
11
Step-by-step explanation:
consecutive interior angles always equal to 180 degrees, so you would add both equations together and equal it to 180 degrees. you would then simplify and solve.
8x-9 + 2+9x = 180
-7 + 17x = 180
-7+7 180+7 = 187
17x = 187
17x/17 = 187/17
x=11
