Answer:
[tex]1.8[/tex]
Step-by-step explanation:
Since the time for the pot of water to boil is inversely proportional to the cooker setting, H, as one goes up, the other must go down:
[tex]T\propto \frac{1}{H}[/tex]
Convert 5 minutes to seconds:
[tex]5\cdot 60=300\:\mathrm{s}[/tex]
Therefore, from the initial data given (When H=6, T=90), the new time is [tex]\frac{300}{90}=3\frac{1}{3}[/tex] larger. Therefore, H must be [tex]3\frac{1}{3}[/tex] times smaller for them to be inversely proportional.
[tex]H=\frac{6}{3\frac{1}{3}}=\boxed{1.8}[/tex]

0=(x-8) (3x-5) show all work
Answer:
x = 8
[tex]x=1\frac{2}{3}[/tex]
Step-by-step explanation:
0 = (x - 8)(3x - 5)
(x - 8)(3x - 5) = 0
x(3x - 5) - 8(3x - 5) = 0
3x² - 5x - 8(3x - 5) = 0
3x² - 5x - 24x + 40 = 0
3x² - 29x + 40 = 0
[tex]x=\frac{-b±\sqrt{b^{2}-4ac } }{2a}[/tex]
Ignore the A before the ±. It wouldn't let me type it correctly.
3x² - 29x + 40 = 0
a = 3
b = - 29
c = 40
[tex]x=\frac{-(-29)±\sqrt{(-29)^{2}-4((3)(40)) } }{2(3)}[/tex]
[tex]x=\frac{-(-29)±\sqrt{841-4((3)(40)) } }{2(3)}[/tex]
[tex]x=\frac{29±\sqrt{841-480} }{2(3)}[/tex]
[tex]x=\frac{29±\sqrt{361} }{2(3)}[/tex]
[tex]x=\frac{29±19 }{2(3)}[/tex]
[tex]x=\frac{29±19 }{6}[/tex]
Two separate equations
[tex]x=\frac{29+19 }{6}[/tex]
[tex]x=\frac{48 }{6}[/tex]
x = 8
[tex]x=\frac{29-19 }{6}[/tex]
[tex]x=\frac{10 }{6}[/tex]
[tex]x=\frac{5 }{3}[/tex]
[tex]x=1\frac{2}{3}[/tex]

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.

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

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.

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

x= 44.1
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hypotenuse
sin 27 = 20/x
x sin 27 = 20
x = 20 / sin 27
x= 44.05378529
Rounding to the nearest tenth
x= 44.1
At the book fair 32 books were sold in the first 2.5 hours. At this rate, how many books will be sold in the 10 hours of the book fair?
Answer:
128
Step-by-step explanation:
set up a proportion of # books sold/hours = # books sold/hours
let 'b' = # books sold
32/2.5 = b/10
cross-multply to get:
2.5b = 320
b = 320/2.5
b = 128
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]

Describe the symmetry of the figure. Identify lines of symmetry, if any. Find the angle and the order of any rotational symmetry. HELP AS SOON AS POSSIBLE!!!
Answer:
No line of symmetry no angle and order of rotational symmetry
There is no line of symmetry, no angle, and order of any rotational symmetry so option (C) will be correct.
What is symmetry?If two figures look an exact shape but their size could be small or big then both figures are called similar figures.
When anything has identical pieces facing one another or revolving around an axis, it is said to be symmetrical.
For example, a square with a side of 10 cm and another with a side of 20 cm both square will be similar.
Given the figure and axis for symmetry
If we fold across the line of symmetry then we can see that neither party can fully cover another
Hence the given figure will not have any symmetry.

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
