♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Suppose the number of students in one of the classes is :

x

So ;

Mr.Lopez \:   \: had \:  \:  \frac{92.5}{100}x \\

_________________________________

Mrs.Foster \:  \: had \:  \:  \frac{19}{20} x \\

So :

Mrs.Foster \:  \: had \:  \:  \frac{19 \times 5}{20 \times 5} x \\

Mrs.Foster \:  \: had \:  \:  \frac{95}{100}x \\

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Ms.Kelly \:  \: had \:  \: 0.9x

Ms.Kelly \:  \: had \:  \:  \frac{9}{10} x \\

Ms.Kelly \:  \: had \:  \:  \frac{90}{100} x \\

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Compare :

\frac{95}{100} x >  \frac{92.5}{100} x >  \frac{90}{100} x \\

Thus :

Mrs.Foster’s  \:  \: class \:  > \: Mr.Lopez’s \:  \:  class \:  >  \: Ms.Kelly’s \:  \:  class \\

Find the volume of the composite figure. Round to the nearest tenth. The base of each pyramid is a square with a side length of
nataly862011 [7]

Answer:

75 cubic inches

Step-by-step explanation:

Given:

The base of each pyramid is a square with a side length of 5 inches

Height of of pyramid is 9 inches.

To find: volume of the pyramid

Solution:

As the base of each pyramid is a square with a side length of 5 inches,

length of the pyramid (l) = base of the pyramid (b) = 5 inches

Height of of pyramid (h) = 9 inches

Volume of the pyramid (V)=\frac{lbh}{3}

On putting values of l, b and h, we get

V=\frac{5\times 5\times 9}{3}=75 cubic inches

Which of the following statements best describes the "grouping method" of factoring trinomials?
Masja [62]

Answer:

  • <em>B. The grouping method of factoring trinomials involves rewriting the bx term into the factors that fit the particular trinomial, and factoring these four terms using grouping</em>

Explanation:

The description may be better explained by applying it to an example.

Example:

  • trinomial: x² - x - 30

  • the general form of a trinomial is a x² - bx - 30

  • comparing with x² - x - 30 the <em>bx term </em>is - x

  • then you must <em>rewrite the bx term, - x,</em> into two terms whose coefficients are factors of 30:

          Two numbers which add up - 1 and multipled are - 30. Those numbers are - 6 and + 5, because -6 + 5 = - 1 and (-6) × (+5) = -30.

           Hence, the two terms are -6x and 5x, and the expression rewritten is:

            x² - 6x + 5x - 30

  • <em>factor these four terms using grouping</em>:

            (x² - 6x) + (5x - 30)

            x(x - 6) + 5(x - 6)

            (x - 6) (x + 5)

Hence, the factored trinomial is (x - 6) (x + 5)
