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 ?

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\pmb{ C's \: 1 \: day's \: work = \dfrac{1}{15}}[/tex]

[tex] \small\sf{ (A + B + C)'s \: 1 \: day's \: work = \frak {\dfrac{1}{10}+\dfrac{1}{12} + \dfrac{1}{15}}}[/tex]

[tex] \longrightarrow \small\frak{ \dfrac{6 + 5 + 4}{60} } [/tex]

Step-by-step explanation:

3 2/5

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

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.

Answer:

  D  The new line would be less steep than the original line.

Step-by-step explanation:

Assuming the slope is change from 3 to 1/3, the new line would be less steep.

__

The steepness of a line increases as the magnitude of the slope increases. The slope 1/3 is less than 3, so a line with that slope is less steep than a line with a slope of 3.

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

(0, 11200)

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

Answer:

x > 0

Step-by-step explanation:

Given :-

And we need to find the value of x for which the expression is defined . The expression is ,

[tex]:\implies[/tex] √[3x²] ÷ √[4x]

As we can see that x is inside the squareroot. So for defining the expression the value of x should be Greater than 0 . As negative inside the squareroot will give rise to imaginary numbers.

Solution :-

[tex]:\implies[/tex] x > 0

In interval notation :-

[tex]:\implies\bf x \in ( 0 , \infty) [/tex]

Therefore x should be Greater than 0 .

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

Hope this helps!
