LCM=2*32*47=3008
while doing LCM u should take all the numbers (common numbers and remaining numbers)
But in HCF only common numbers are take for eg .here,HCf is 2because 2 is the only number that divides both the number.

% of 400,000 = 100,000
Answer:
25%
Step-by-step explanation:
100,000/400,000 x 100
= 1/4 x 100
= 25%
Hence, 100,000 is 25% of 400,000
Feel free to mark this as brainliest :D
Answer:
x/100 x 400,000 = 100,000
x100 x100
400,000x = 10,000,000
Divide by 400,000 on both sides:
X = 25%

outside the court ard is 120 m“, find the width of the path.
A square garden has an area of 441 m². If the path of uniform width surrounding inside the
garden is 216 m², find the width of the path.
Answer:
Area of a square garden = 2, 500 m².
Length of the side of the garden = √2,500 = 50 m.
Width of the path = 2.5 m.
Path is inside the garden.
Width of the garden that is inside (enclosed) by the path:
50 - 2 * 2.5 = 45 m.
Length of the garden inside by the path : = 45 m.
So the area of garden inside the path = 45 * 45 m²
= 2, 025 m².
Area of the path = 2, 500 - 2, 025
= 475 m².
Cost of laying the path = Rs 25 /m² * 475 m²
= Rs 11, 875.

How to find circumference
A line passes through the point (8,-4) and has a slope of 5/4
Answer:
y = 5/4x - 14
Step-by-step explanation:
Given:
Passes through (8, -4)
Slope (m) = 5/4
Slope-intercept equation:
y - y1 = m(x - x1)
y - (-4) = 5/4(x - 8)
y + 4 = 5/4x - 10
y = 5/4x - 14
The text book store sold a combined total of 326 history and chemistry textbooks in a week. The number of chemistry textbooks sold was 86 less than the number of history textbooks sold. How many textbooks of each type was sold?
Answer:
The sentence
"The Number of Chem textbooks sold is 86 less than the number of History textbooks"
This seems to be the confusing part.
Now look at it this way...
'If CHM text is 86 less than History text... It also means that History Text is 86 More than CHM'
This expression can be written as
Let History Text be "H"
Let CHM text be "C"
C - 86 = H
or
C=H + 86.......1
First line of this question is interpreted thus
H + C = 326.......2
From eqn 1... C=H+86
Substitute into Eqn 2
H + C=326
H + (H+86)=326
H+H=326-86
2H=240
H=240/2
H=120.
C=H+86
C=120+86
C=206.
This answer is correct... Why?
The key statement says .. The Number of CHM sold is 86 less than History...
Also interpreted as
The Number of CHM – 86 = History
206 - 86 =120.
Have a great day!!!

A radioactive substance decays to 30% of its original mass in 15 months. Determine the half-life of this radioactive substance to the nearest tenth. Show your work.
please help
Answer:
The half-life of this radioactive substance is of 8.6 months.
Step-by-step explanation:
Exponential decay of an amount:
The equation that models an amount after t units of time, subject to exponential decay, is given by:
[tex]A(t) = A(0)(1-r)^t[/tex]
In which A(0) is the initial amount and r is the decay rate, as a decimal.
A radioactive substance decays to 30% of its original mass in 15 months.
This means that [tex]A(15) = 0.3A(0)[/tex]. We use this to find 1 - r.
[tex]A(t) = A(0)(1-r)^t[/tex]
[tex]0.3A(0) = A(0)(1-r)^{15}[/tex]
[tex](1-r)^{15} = 0.3[/tex]
[tex]\sqrt[15]{(1-r)^{15}} = \sqrt[15]{0.3}[/tex]
[tex]1 - r = (0.3)^{\frac{1}{15}}[/tex]
[tex]1 - r = 0.9229[/tex]
So
[tex]A(t) = A(0)(0.9229)^t[/tex]
Determine the half-life of this radioactive substance to the nearest tenth.
This is t for which A(t) = 0.5A(0). So
[tex]A(t) = A(0)(0.9229)^t[/tex]
[tex]0.5A(0) = A(0)(0.9229)^t[/tex]
[tex](0.9229)^t = 0.5[/tex]
[tex]\log{(0.9229)^t} = \log{0.5}[/tex]
[tex]t\log{0.9229} = \log{0.5}[/tex]
[tex]t = \frac{\log{0.5}}{\log{0.9229}}[/tex]
[tex]t = 8.6[/tex]
The half-life of this radioactive substance is of 8.6 months.

The odds of winning a contest are approximately 5:1476. How many winners are there likely to be if there are 50000 participants?
Answer:
Approximately 169
Step-by-step explanation:
Set up as fractions and use cross multiplilcation to solve for the unknown.
These are our fractions from the information we are given; the winners represent the numerators (and x is the unknown, becuase we don't yet know how many winners there will be with 50000 participants). Note that the denominator on the first fraction is (1476 + 5) because we want it to represent TOTAL amount of particpants in the ratio:
[tex]\frac{5}{1481} = \frac{x}{50000}[/tex]
Now cross multiply by multiplying numerators and denominators that are ACROSS from each other, so 5 * 50000 and 1481 * x; now we have:
250000 = 1481x
Now to isolate x (to know its value) we need to divide both sides by 1481, and we are left with:
168.8 = x
But I rounded up to 169.

Answer:
y = 5 sin (2x) + 4
Step-by-step explanation:
this is sines function,
the amplitude is [9 - (-1)]/2 = 10/2 = 5
the period is 2πx/π = 2x
the x-axis of actual function is at y = 4
so, the function is :
y = 5 sin (2x) + 4
A clothing vendor estimates that 78 out of every 100 of its online customers do not live within 50 miles of one of its physical stores. Using this estimate, what is the probability that a randomly selected online customer does not live within 50 miles of a physical store? .78 .50 .28 .22
Answer:
[tex]p' = 0.22[/tex]
Step-by-step explanation:
Given
[tex]p = \frac{78}{100}[/tex]
Required
Probability that a [tex]customer[/tex] does [tex]not[/tex] live [tex]within[/tex] [tex]50[/tex] miles
To do this, we make use of complement rule;
Which states that:
[tex]p + p' = 1[/tex]
Make p' the subject
[tex]p' = 1 - p[/tex]
So, we have:
[tex]p' = 1 - \frac{78}{100}[/tex]
Express fraction as decimal
[tex]p' = 1 - 0.78[/tex]
[tex]p' = 0.22[/tex]

What are the coordinates of the foci of the conic section shown below?
Answer:
((y + 2) ^ 2)/25 - ((x - 3) ^ 2)/4 = 1 O A. ( (3, - 2 plus/minus sqrt(21)) B. (3, - 2 plus/minus sqrt(29)) O B. O c. D . (3 plus/minus sqrt(21), - 2); (3 plus/minus sqrt(29), - 2)
The foci of the hyperbola will be (3, -2 + √29) and (3, -2 - √29). Then the correct option is B.
What is a hyperbola?The hyperbola is the locus of a point such that the difference of distance from point P to two non-movable points. These two points are called foci of hyperbola.
The hyperbolic equation is given as,
(y - k)² /a² - (x - h)² /b² = 1
Then the foci of the hyperbola are given as,
(h, k + c) and (h, k - c)
The equation of the hyperbola is given below.
(y + 2)² /25 - (x - 3)² / 4 = 1
Compare the equations, then we have
(h, k) = (3, -2)
a² = 25
b² = 4
Then the value of 'c' is given as,
c² = a² + b²
c² = 25 + 4
c² = 29
c = √29
Then the foci of the hyperbola will be (3, -2 + √29) and (3, -2 - √29). Then the correct option is B.
