This percentage can be calculated as part / whole:
p =  \frac{900000000}{3500000000} \\ p = 0.257

Approximately 25.7 percent.

If we are going to find the percentage of a total body that a specific group of something makes up, we are going to want to divide the frequency of the specific body by the frequency of the total body. Essentially, divide the specific number by the total number. After you have done this, multiply by 100 and add a % sign.


In this case, the specific number would be 900 million, since that is representing the frequency of the smaller group. The total number would be 3.5 billion. Dividing will give us:

\dfrac{900,000,000}{3,500,000,000} = \dfrac{9}{35}


Multiplying by 100 will give us:

\dfrac{9}{35} \cdot 100 = \dfrac{900}{35} \approx 25.7 \,\%


Our answer is 25.7%.

For any perfect square trinomial (quadratic), the constant term (last term) must be positive.
Ronch [10]

Answer:

For the perfect square trinomial (quadratic) i.e. \left(x\:+\:3\right)^2, the constant term (last term) is positive.

Step-by-step explanation:

"Perfect square trinomials" are termed as the quadratics that are the outcomes of squaring binomials.

For example:

\left(x\:+\:3\right)^2

\mathrm{Apply\:Perfect\:Square\:Formula}:\quad \left(a+b\right)^2=a^2+2ab+b^2

a=x,\:\:b=3

=x^2+2x\cdot \:3+3^2

=x^2+6x+9

Therefore, for the perfect square trinomial (quadratic) i.e. \left(x\:+\:3\right)^2, the constant term (last term) is positive.

Find the coordinates of the point <br> 3/10 of the way from A to B.
meriva
The horizontal distance from A to the point = 3/10 * 14 = 4.2, so the c coordinate of the point is -3+ 4.2
= 1.2.
Vertical distance = 3/10 * 12 = 3.6
So the y coordinate = -5+ 3.6
= -1.4.
Answer is (1.2, -1.4)

The number of marbles of different colors stored in a hat is listed below:
ivann1987 [24]

Answer:

12.5%

Step-by-step explanation:

I warn you, I'm not positive I'm correct.

First I added 8+10+6 and got 24

I divided that by 3 and got 8

I divided 100 by 8 because if you cross multiply 1/8 and x/100 you would get 8x = 100

100 ÷ 8 = 12.5

So I got 12.5%

Which of the following shows the best way to set up the product of (2x - 5) and<br> (4 - 3x + 4.)?
masha68 [24]

Answer:

  C

Step-by-step explanation:

It usually works best to use the polynomial with fewer terms as the multiplier. A row of partial products is written for each term of the multiplier, so the fewer terms will result in fewer rows of partial products.

In order to keep like terms together, it is preferable to allocate a separate column of the multiplication tableau to each power of the operands or product. This means we want to make note of the fact that the cubic multiplicand has a coefficient of 0 for its x^2 term.

The best setup is the one shown in the attachment.
