The least common multiple is divisible by both a and b and it is the smallest positive integer divisible by both. The same food last for 4 girls will last 12 days.
What is LCM?The least common multiple that is divisible by both a and b is the smallest positive integer, lowest common multiple, or smallest common multiple of two numbers a and b, generally indicated by LCM.
The relationship between work and time is given by,
W = R × M × T
where W is the work, R is the rate of work, T is the time taken to do the work, and M is the number of people doing the work.
Given that 8 girls have enough food for 6 days. Therefore, the amount of food that a girl needs for a day is,
Amount of food that the girls need for a day = 1/(8×6) = 1/48
Now, if the same food is available then the time for which the food will last is,
[tex]\rm Time = \dfrac1{(4 \times \frac1{48})}[/tex]
= 12 days
Hence, the same food last for 4 girls will last 12 days.

if -2x+ y =6 and -7x-4y=-8 are true equations what would the value of -9x-3y
Answer:
[tex]-\frac{106}{5} or -21.2[/tex]
Step-by-step explanation:
First we would have to get x and y-values by solving systems of equations:
isolate one of the variable from any of the first 2 equations given:
-2x+ y =6 would be y = 2x + 6 when y is isolated.
now plug this equation in for the y given in the second equation:
-7x -4(2x + 6) = -8
Now solve to get the x-value,
-7x - 8x - 24 = -8
-15x - 24 = -8
-15x = 16
x = [tex]-\frac{16}{15}[/tex] or -1.06
To solve for y-value, substitute the gotten x-value in any of the 2 equations and solve:
y = 2([tex]-\frac{16}{15}[/tex]) + 6
y = [tex]\frac{58}{15}[/tex] or 3.86
Now that we have the x and y-values, substitute them in for the 3 equation given:
-9([tex]-\frac{16}{15}[/tex]) -3( [tex]\frac{58}{15}[/tex])
=> [tex]-\frac{106}{5}[/tex] or -21.2 = Final Answer

a can do a piece of work in 10 days, B in 12 days and C in 15 days how long will it take them it together to complete it.
Answer:
that would depend on how long the project is
A can do a piece of work in 10 days, B in 12 days and C in 15 days. How long will it take them it together to complete it ?
Explanation -:We observe here that A can do the work in 10 days; B can do the same work in 12 days whereas C can do the same work in 15 days. We are asked to calculate how much time will it take if three of them will work together.
We will solve this problem with traditional method.
Let us solve the question.
[tex] \small\pmb{ A's \: 1 \: day's \: work = \dfrac{1}{10}}[/tex]
[tex] \small\pmb{ B's \: 1 \: day's \: work = \dfrac{1}{12}}[/tex]

[tex] \small\sf{ (A + B + C)'s \: 1 \: day's \: work = \frak {\dfrac{1}{10}+\dfrac{1}{12} + \dfrac{1}{15}}}[/tex]
L.C.M of 10, 12 and 15 is 60[tex] \longrightarrow \small\frak{ \dfrac{6 + 5 + 4}{60} } [/tex]
[tex] \longrightarrow \small\frak{ \dfrac{15}{60} = \dfrac{1}{4} } [/tex]
Hence A,B and C can finish the work in 4 days.[tex] \rule{40mm}{3pt}[/tex]

The volume of this sphere is 904.32 cubic inches. What is the surface area of this sphere?
Use a 3.14 and round your answer to the nearest hundredth.
Answer:
A = 4 pi R^2 V = 4/3 pi R^3
A / V = 3 / R
Also, R = (3 * V / 4 * pi)^1/3 = (3 * 904.32 / (4 * pi))^1/3 = 6 in
So A = 3 / 6 * V = 1/2 * 904.32 = 452.16 in^2
The surface area of the sphere is S = 452.39 inches²
What is a Sphere?A sphere is symmetrical, round in shape. It is a three dimensional solid, that has all its surface points at equal distances from the center. It has surface area and volume based on its radius. It does not have any faces, corners or edges.
The Surface Area of a Sphere = 4πr²
The Volume of a Sphere = ( 4/3 ) πr³
where r is the radius of the sphere
Given data ,
Let the volume of the sphere be V = 904.32 inches³
Let the surface area of the sphere be S
And , Volume of a Sphere = ( 4/3 ) πr³
In this case, we are given that the volume of the sphere is 904.32 cubic inches, so we can set up an equation:
904.32 = (4/3)πr³
Solving for r:
r³ = (3/4) x (904.32 / π)
r ≈ 6.0 inches (rounded to one decimal place)
Now that we know the radius, we can use the formula for the surface area of a sphere:
A = 4πr²
Plugging in the value of r:
A = 4 x 3.14 x 6.0²
A ≈ 452.39 inches² (rounded to two decimal places)
Hence , the surface area of the sphere is approximately 452.39 square inches.

Option C is the only table that represents a data set that could be fit to a normal distribution curve.
In a normal distribution, the data is symmetrically distributed around the mean, and the percentages decrease as you move away from the mean.
Option C exhibits this characteristic, where the percentages are highest at the mean values (5, 6, 9, 10) and decrease as you move away from the mean.
Where as the tables in options A, B, and D do not exhibit the characteristics of a normal distribution as the percentages do not decrease symmetrically away from the mean values.

In ΔNOP, n = 800 inches, ∠P=97° and ∠N=32°. Find the length of o, to the nearest inch.
9514 1404 393
Answer:
1173 in
Step-by-step explanation:
The measure of angle O is ...
O = 180° -N -P = 180° -32° -97° = 51°
The law of sines tells you ...
o/sin(O) = n/sin(N)
o = n·sin(O)/sin(N) = (800 in)·sin(51°)/sin(32°)
o ≈ 1173 in
5. Zhao purchased a used car for $11,500. This make and model used car
straight line depreciates to zero after 9 years. (a) Identify the coordinates
of the x and y intercepts. *
Answer:
(9, 0)
(0, 11200)
Step-by-step explanation:
The x - intercept is the value of x when y = 0 ; similarly, the y - intercept is the value of y, when x = 0
From the given relation :
y = price, x = number of years
Price after 9 years of usage, the price of car is depreciated to 0
Hence,
x = 9, y = 0
(9, 0)
At purchase, the value of car is 11,200 ;
At this price, the number of years of usage of car is 0
Hence ;
x = 0 ; y = 11200
