Answer:

\displaystyle a = \frac{1+vh}{v}

Step-by-step explanation:

we want to figure out a value of a for the following condition

\displaystyle va - vh = 1

to do so factor out v;

\displaystyle v (a - h )= 1

divide both sides by v which yields:

\displaystyle  \frac{(a-h) \cancel{(v)}}{ \cancel{v}}=  \frac{1}{v}

therefore,

\displaystyle a-h =  { \frac{1}{v}}

now,add h to both sides:

\displaystyle a =  \frac{1}{v}+h

further simplification if necessary:

\displaystyle a =\boxed{   \frac{1+vh}{v}}

<h2>Given:-</h2>
  • \sf{va-vh=1   }

<h2>To find:-</h2>

  • \sf{ value~ of ~a  }

<h2>Solution:-</h2>

  • \sf{ va-vh=1  }

factor out of v

  • \sf{v(a-h)=1   }

Dividing both sides by (v)

  • \sf{\dfrac{v(a-h)}{(v)}=\dfrac{1}{(v)}   }

cancel out (v)

  • \sf{\dfrac{\cancel{v}(a-h)}{\cancel{(v)}}=\dfrac{1}{(v)}   }

  • \sf{ a-h=\dfrac{1}{v}  }

add h in both sides

  • \sf{a-h+h=\dfrac{1}{v}+h   }

cancelout h

  • \sf{a-\cancel{h}+\cancel{h}=\dfrac{1}{v}+h   }

  • \sf{a=\dfrac{1}{v}+h   }

  • \boxed{\sf{a=\dfrac{1+vh}{v}  } }

\sf{   } \sf{   }

<h3><u>Therefore</u><u>:</u><u>-</u></h3>

the value of a if va- vh is equals to 1 is \bold{\dfrac{1+vh}{v}   }

y^2\sqrt[8]{8}

Step-by-step explanation:

\sqrt[8]{8*y*y*y*y*y*y*y*y*y*y*y*y*y*y*y*y}

Since there are eight y's in two groups we can take them out which turns into

y^2\sqrt[8]{8}

Which expression can be used to find the volume of the sphere?
Kryger [21]

Answer:

They used 3.14 for pi:

V=\frac{4}{3} \pi r^3

V=\frac{4}{3} (3.14)(5)^3

Step-by-step explanation:

V=\frac{4}{3}\pi r^3 is the volume of a sphere with radius r.

I think that is the diameter given in the picture.

The radius is half the diameter.

So the radius is 5 since the diameter is 10.

Plug in this gives you:

V=\frac{4}{3} \pi (5)^3

The number of responses to a survey are shown in the Pareto chart. The survey asked 1052 adults how they would grade the quality
Goryan [66]

Answer: (a) P(no A) = 0.935

              (b) P(A and B and C) = 0.0005

              (c) P(D or F) = 0.379

              (d) P(A or B) = 0.31

Step-by-step explanation: <u>Pareto</u> <u>Chart</u> demonstrates a relationship between two quantities, in a way that a relative change in one results in a change in the other.

The Pareto chart below shows the number of people and which category they qualified each public school.

(a) The probability of a person not giving an A is the difference between total probability (1) and probability of giving an A:

P(no A) = 1-\frac{68}{1052}

P(no A) = 1 - 0.065

P(no A) = 0.935

b) Probability of a grade better than D, is the product of the probabilities of an A, an B and an C:

P(A and B and C) = (\frac{68}{1052})(\frac{258}{1052})(\frac{327}{1052})

P(A and B and C) = \frac{5736888}{1164252608}

P(A and B and C) = 0.0005

c) Probability of an D or an F is the sum of probabilities of an D and of an F:

P(D or F) = \frac{269}{1052} +\frac{130}{1052}

P(D or F) = \frac{399}{1052}

P(D or F) = 0.379

d) Probability of an A or B is also the sum of probabilities of an A and of an B:

P(A or B) = \frac{68}{1052} +\frac{258}{1052}

P(A or B) = \frac{326}{1052}

P(A or B) = 0.31

What is the balue of x in the proportion 2 1/4 / x= 1 1/2/3/35?
never [62]

Answer:

5 2/5

Step-by-step explanation:

(2 1/4) / x = (1 1/2) / (3 3/5)

so

x = (2 1/4) * (3 3/5) / (1 1/2)
