Answer:

The number of seashells he have in his collection all together is 140.

Step-by-step explanation:

Given:

Stanley has a collection of seashells. He found 35% of his collection on Florida beaches.

Stanley has 49 seashells from Florida.

Now, to find the number of seashells of his collection altogether.

Let the number of seashells all together be x.

Percentage of seashells found on Florida beaches = 35%.

Number of seashells found on Florida beaches = 49.

Now, to get the number of seashells altogether we put an equation:

35\%\ of\ x=49.

⇒ \frac{35}{100} \times x=49

⇒ 0.35\times x=49

⇒ 0.35x=49

Dividing both sides by 0.35 we get:

⇒ x=140.

Therefore, the number of seashells he have in his collection all together is 140.

(X to the fourth power) squared equals
Viktor [21]

Answer:

(x^4)^2=x^8

Step-by-step explanation:

Because of the power of a power property, which states that (x^n)^m=x^{n\times{m}}, where m and n are real numbers, the expression you mentioned can be simplified by applying this property like this: (x^4)^2=x^{4\times2}=x^8

If one root is the square of the other in the equation 8+mx+27x²=0,find the value of m​
aleksklad [387]

Answer:

The value of m is -30.

Step-by-step explanation:

Let 27\cdot x^{2}+m\cdot x +8 = 0, we notice that expression is a second order polynomials. We can rearrange the polynomial and use factorization to calculate all roots:

x^{2}+\frac{m}{27}\cdot x + \frac{8}{27} = 0 (1)

-x^{2}-x = \frac{m}{27} (2)

x^{3} = \frac{8}{27} (3)

From (3) we find the least root:

x = \sqrt [3]{\frac{8}{27}}

x = \frac{2}{3}

By (2) we have the value of m:

m = -27\cdot (x^{2}+x)

m = -30

An airplane can seat up to 175 passengers. The airline has already sold 87 tickets for a flight on the airplane. Which
spayn [35]

The inequality is solved, and then, the graph is given at the end of this question.

------------------

  • 87 tickets have already been sold.
  • x can still be sold.
  • In total, the number of tickets sold is 87 + x.
  • The airplane can seat 175 passengers, thus, the total can be at most 175, that is:

87 + x \leq 175

x \leq 175 - 87

x \leq 88

  • The solution is given on a graph at the end of this answer.
